Torque Limiters SelectionCROSS+MORSESelection Procedure1. Determine if the Torque Limiter is to be mounted on input(driver) or output (driven) shaft. Mounting on input shaft isnormally lowest cost, and spreads load on Limiter body inoverload slip, but if frequent slip occurs longer wear life offriction facings is obtained with the Torque Limiter on theoutput shaft.Dimensions6TorqueLimiterModelChain SizeModelNo.Torque Nm = H.P. x 7124 Torque Nm = kW x 9550R.P.M.R.P.M.3.

Using capacity below, confirm selection of Torque Limiter.For machines under constant supervision or with motoroverload sensors the 10 sec values should be used. Forunmanned machines combination of torque and speedshould always be within power ratings over 5 min to avoiddeterioration of components parts due to temperaturebuild-up. If necessary a larger Torque Limiter may have tobe selected to provide sufficient heat dissipation.6.

Sheargard <strong>Overload</strong> <strong>Clutches</strong>CROSS+MORSEThe Cross Sheargard clutch complements the range ofTorque Limiters by providing machinery protection onapplications where accurate torque control and shaftsynchronisation are necessary; and when in the event of anoverload, total disengagement of driving and drivenmembers is required.The design of the Sheargard <strong>Clutches</strong> provides for thetransmission of high torques (up to 125,000 Nm) with acompact, low inertia unit. Standard stock products enablesprompt delivery, at low cost of shearpin chain sprockets andflexible shaft couplings. The provision of an optional motormonitor plate enables disconnection of the power supplyand / or operation of alarm signals in the event of anoverload when used in conjunction with a limit switch orproximity switch.The basic advantages of the well proven “Howdon” wedgeshearpin, have been combined with a clutch designed foreconomic production, with component parts sized to enablethe use of the existing range of torque limiter platewheeland chain flexible coupling to enable supply from stock ofcomplete drive assemblies. For higher speed applications arubber coupling is available.In the diagram Hub “A” and Flange “B” have matchingtapered slots cut axially in their periphery, into which the“Howdon” wedge-shaped shearpins “C” are inserted andfirmly clamped by two self-locking screws. Torque istransmitted by the wedge which has a reduced diameterneck in mid-span “D”’ designed to shear when thepre-determined torque is exceeded, so allowing the sleeveto rotate freely on the hub.The Cross Sheargard by virtue of its design offers a number of advantages overalternate overload protection systemsPower Transmission Solutions1. Simple DesignIn a Shearpin the full shear strength is directly available as a frictionless driving force. The use of up to three shearpins provideshigh torque capacity within a compact unit, keeping both inertias and costs to a minimum. Several ratings of pin for eachclutch size provides over 200 stock torque ratings. The Sheargard can be used with chain sprockets, gears, belt drives or shaftcouplings. In the event of an overload, the wedge shaped shearpins are easy to locate, and quickly replaced by removal of twoself-locking screws and broken halves of shearpin, and replacement with a new wedge pin.2. Accurate Torque RatingsInaccuracy of torque setting in conventional shearpin couplings is caused by non-uniform shear necks, and poor fit of the pinwith its mating surfaces. The “Howdon Wedge” pins are precision turned to a constant form and can be expected to fracturewithin ±10% of catalogue rating. The wedge pins are rigidly located in the mating grooves so totally eliminating frettingfatigue failures, and ensuring zero backlash making it ideal for indexing and reversing drives. The clamping of the pin into thewedge angle ensures positive radial and axial location. The design also ensures load sharing is achieved when a number of pinsare used for higher torque drives, enabling different rated pins to be used in one clutch.3. ReliabilityThe “Howdon Wedge” pins are naturally “fail-safe” under all conditions. They are not affected by changes in temperature orhumidity and are tolerant of most environment conditions. Sizes 350-900SG standard pins are manufactured from brass toavoid sparking in the event of overload, thus making them suitable in volatile atmospheres. The unconventional shape of thewedge pins prevents the fitment of alien pins ensuring safety and product liability requirements are met at all times. Theperipheral location of the wedge pins enables easy inspection, and clear colour coding of the pins ensures simple checking oftorque setting.4. AvailabilityCross Sheargard <strong>Clutches</strong> and Couplings are carried in stock with minimum pilot bore. Units can be finished bored and keyedto customer’s specifications through a 48 hour rework service. A large stock of standard rated wedge pins, colour codedaccording to capacity ensures instant spares availability.5. Low Cost <strong>Protection</strong>The cost of Sheargard <strong>Clutches</strong> is kept low by volume production techniques, so providing the customer with a low costsynchronised, reliable overload protection device.9T el +44 121 360 0155 Fax +44 121 325 1079 Email sales@crossmorse.comCD ContentsCatalogue Selection INDEX<strong>Overload</strong> <strong>Protection</strong> <strong>Clutches</strong> :INDEXBACKNEXT

Crossgard <strong>Overload</strong> CouplingsCROSS+MORSEPower Transmission SolutionsThe Crossgard series of overload protection clutches all use sprung loaded balls locked in detents toprovide drive and overload control. The balls are random positioned in the clutch so drive can only beengaged in one relative angular position between driver and driven shafts, so ensuring fullsynchronisation of the drive at all times. In the event of an overload the balls are driven out of theirdetents to release the torque, and cause axial movement of the pressure plate which can be used toactuate a limit switch or proximity sensor to isolate the drive. All units are fitted with a torque indicatorto enable simple setting of the desired torque rating. There are three basic types of Crossgard <strong>Clutches</strong>all of which are available as flexible shaft couplings, types CG, CGX and CGZ.Crossgard Principles of OperationDuring normal operation torque is transmitted between hub and driving flange by a number of balls located in the flangeengaged in detents in the hub under load applied by disc springs. The balls are arranged in irregular angular positions to ensurere-engagement can only occur at one angular position between hub and flange. When an overload occurs the balls are driven outof their detents and then roll between the hub and pressure plate. The pressure plate moves axially a sensor plate which can beused to activate a proximity or limit switch. Torque is varied by adjusting the spring load on the pressure plate by tightening orloosening adjusting nuts.Type CG Crossgard Clutch Pages 15-17CG Crossgard <strong>Clutches</strong> are a low cost, simple designsuitable for general purpose applications. The clutchesprovide full overload protection of drives which requiresynchronisation to be maintained at all times. Followingoverload the clutches are automatically reset by slowrotation of input drive once the overload cause is cleared.Four sizes of clutch provide a torque range 10Nm to 1080Nm with operating speeds to 700rpm. Torque settings areaccurate to ±10% even after repeated tripping.Also can be supplied with roller chain or elastomericcoupling.Use CG Clutch:• For general purpose applications.• Where drives are inaccessible.• For chain and low speed belt drives.• In wrapping and packaging machines.• On bakery and bottling machines.• For conveyors and on sliding door drives.Design FeaturesCrossgard clutches have been designed to provide the customer with a reliable, simple to operate clutch, all three typesincorporating the following design features.Drive SynchronisationNon symmetrical arrangement of the drive balls and pockets allows only one angular position of engagement of drive,ensuring input and output are always synchronised.Bi-directional driveThe clutches function equally in either direction of rotation, and are suitable for reversing drives.Visual Torque MeterAll units have a scale on the adjusting nut to enable the set torque to be determined by reference to torque charts. Settingcan also be verified at any time by visual check.Simple Torque setting and adjustmentRequired torque is set by turning the adjusting nut, and setting off torque scale.<strong>Overload</strong> MonitoringAll units incorporate a sensor plate which moves axially when overload occurs to trigger a proximity or limit switch toisolate power to motor and activate failure indicators.Stock availabilityAll standard Crossgard clutches are carried in stock with pilot bore. Units can be supplied with finished bore, keyseat andsetscrews, fitted with platewheels; or complete with flexible coupling on 72 hours lead time.13T el +44 121 360 0155 Fax +44 121 325 1079 Email sales@crossmorse.comCD ContentsCatalogue Selection INDEX<strong>Overload</strong> <strong>Protection</strong> <strong>Clutches</strong> :INDEXBACKNEXT
Crossgard <strong>Overload</strong> <strong>Clutches</strong>and Selection ProcedureCROSS+MORSEType CGX Crossgard Clutch Pages 18/19High technology and precision is demanded in indexing and the positionof equipment in modern machinery. The CCX Crossgard satisfies thedemands for precision and performance and provides overloadprotection for modern machinery. CGX <strong>Clutches</strong> through their uniquedesign provide backlash free, fail-safe, overload protection. Highprecision of trip torque is obtained with settings within ±3% accuracy,and very little motion is lost during tripping. An innovative ball andwedge mechanism is used to prevent backlash, and this is furtheremployed in the coupling version to compensate for angular or parallelerror or axial displacement with no loss in torsional rigidity. Five sizes ofclutches and couplings have range 1.7 Nm to 785 Nm withmaximum shaft speeds of 1400rpm. Units automatically reset afteroverload by slow shaft rotation.Use CGX Clutch:• For precision positioning indexing drives.• For accurate mechanical overload protection.• For zero backlash drives.• On output shafts on cam boxes and Geneva mechanisms.• On servo motor drives and robotics.• In printing machinery.• On N.C. machine tools and machining centres.Type CGZ Crossgard Clutch Pages 20/21The CGX <strong>Clutches</strong> incorporate a locking mechanism which restrainsspring pressure being applied to the driving balls following anoverload. Following an overload the input drive can continue torotate freely enabling the clutch to be used for shaft speeds up to1800 rpm. After the machine has been stopped following an overloadthe CGZ can only be reset by applying an axial load on the pressureplate. The clutch can also be used as an on-off clutch. Four sizes havetorque range 2.4 Nm to 450 Nm, with accuracy ±10%. An elastomericcoupling is also available.Use CGZ Clutch:• For high speed drives - direct motor shaft.• Where manual re-engagement preferred.• As ON-OFF clutch.• For machine tool drives.• On textile and paper making machinery.14Crossgard SelectionPower Transmission SolutionsLike other overload devices,it is best to position the Crossgard nearest the driven equipment where the overload ismost likely to occur. Tripping torque should be at least 25% greater than the operating torque to compensate for motorstarting torque and intermittent, shock and reversing loads.Selection Method1. Selecting the trip torque.Trip torque should be set equal to the maximumamount of torque which can be applied based onsuch conditions as the strength of the machine andload. When it is not clear what the maximumamount of torque is, calculate the rated torque fromthe rated output and the rpm of the shaft ontowhich the Crossgard is to installed, and multiplythis figure by the service factor. The result may betaken as the trip torque.Tripping Torque= Operating x SFTorque Nm=Power kW x 9550RPM2. Select Clutch or Coupling where torque is mid rangeof rating to allow maximum on-site adjustment.3. Check shaft diameters can be accommodated, if not alarger unit will be required.4. Ensure shaft speeds are within limits of unit selected.5. For coupling check alignment requirements.6.

Cross Safegard <strong>Overload</strong> <strong>Clutches</strong>CROSS+MORSEThe Safegard CS series <strong>Overload</strong> <strong>Clutches</strong> were developed toprovide overload protection for the transmission of high torqueswithin a compact unit. Directly interchangeable with other unitsin the market, this series offers low cost protection with aminimum of maintenance and long reliable service life.Safegard CS series are offered in two basic types, the standardtype, available in 6 sizes for bores up to 65mm, with torque rangeof 2.5 to 1800Nm, see pages 24/25, provide optimum speed andtorque capabilities; and the Mini type, available in 4 sizes for boresup to 45mm, with torque range 2.5 to400Nm, see pages 26/27,for a lower cost option for slower speed drives. Both types areavailable as basic clutch, and also as shaft couplings. The basicclutch is offered in three basic designs to enable alternate methodsfor connecting driven components.Four modes of drive operation are available, to suit therequirements of different applications, as outlined below, theprinciples of operation of each being detailed opposite.Power Transmission SolutionsThe Safegard CSF Clutch uses a large number of equally spaced balls to provide the drive, and the clutch ratchets from onedrive position to the next in the event of an overload. The design allows for high operating speeds, and the possibility torecapture drive in the event of an inertia created overload during starting, but do not provide any synchronisation betweeninput and output.The Synchron CSY Clutch uses 7 rollers unequally spaced to provide the drive, ensuring that there is only one position ofengagement of the drive, enabling full synchronisation between driver and driven shafts.The Safe Lift CSL Clutch has a retaining ring to prevent disengagement of the drive, but allowing sufficient movement toactuate a limit switch. This clutch is ideal on applications where components cross one another’s path, as synchronisation ismaintained even when clutch has overloaded. The clutch also controls forward inertia drives.The Contact-Free CSZ Clutch totally disengages in the event of an overload, and requires an outside force to be re-engaged.This enables the clutch to be operated at higher speeds, and also to be used on applications where it is undesirable to stop themotor quickly. The requirement of an external force to re-engage ensures the machine can be checked prior to a restart.Safegard Series <strong>Clutches</strong> offer the following operating advantages:• Long Service Life• Cater for Frequent <strong>Overload</strong>s• No Maintenance required• Standardised SizesMethod of Torque AdjustmentTorque Adjustment on Safegard series<strong>Clutches</strong> is relatively simple process by thefollowing procedure.Refer to diagram below, to adjust theTorque on a Clutch first remove screws 8 or8A to permit free rotation of adjusting nut 7.If first adjustment manually tighten theadjusting nut 7 until it is in contact with thesprings. Insert a C spanner ‘A’ into slots D,or a face wrench ‘C’ into holes D andtighten the nut clockwise to achievedesired Torque as indicated by thenumber of indents E moved.

Cross Safegard CS Clutch TypesCROSS+MORSESafegard CSFDuring normal operation the drive is transmitted by thesliding hub 2, which is connected by a spline to the mainhub 1, and via a ring of balls 4a to the output flange 3.Drive is maintained by the springs 6 exerting pressure onflange 2, so keeping the balls in their respective indents inflange 2 & 3.When an overload occurs the balls ride up the indentspushing flange 2 back which will actuate limit switch 9.During overload conditions plain bearing 5 maintainsconcentricity and ensures free running. The balls willre-engage in the nearest indents when the overload isremoved. Torque adjustment is by rotation of nut 7.Safe Lift CSLThe Safelift clutch is of identical design and operation tothe Synchron clutch with the addition of a restricting ring10 which prevents full dis-engagement of the clutch in theevent of an overload; thus maintaining drive at all times.An overload still causes the rollers to ride up the detentssufficient to activate the limit switch 9, but they areprevented from totally disengaging. On these units it isessential that a limit switch is used to turn off the drive.These units are ideal when high inertia loads are involvedto prevent on running of the driven equipment, also theycan be electrically isolated during starting to ignoretripping at that time.Torque adjustment is by rotation of nut 7.Synchron CSYPower Transmission SolutionsThe Synchron clutch functions in much the same way asthe Safegard, and has similar construction in except theballs 4a are replaced by seven rollers 4b. The rollers areunequally spaced so the clutch will only engage drive inone angular position, providing full synchronisation of thedrive.When an overload occurs the rollers ride up the indentspushing flange 2 back which will actuate limit switch 9.During overload conditions plain bearing 5 maintainsconcentricity and ensures free running. The rollers willre-engage in the nearest indents when the overload isremoved. Torque adjustment is by rotation of nut 7.Contact Free CSZThe Contact-free clutch is based on the Synchron clutchwith modification to the outer flange 2, and the addition oflocking assembly parts 10/11/12. In normal drive mode thepressure from the spring is conveyed to the flange 2 via thepressure plate 11and locking ball race 12. In the event of anoverload the flange 2 is still pushed back, but this actionalso forces the locking balls inwards forcing the pressureplate 11 to move back from the locking ring 10. In thetripped condition the locking balls 12 apply no axial load tothe outer flange 2 and thus the clutch will not re-engage,but instead runs totally free. To re-engage drive the outerflange 2 and output flange 3 must be correctly aligned,andthen a light axial load applied to the outer flange to moveit back into engagement.T el +44 121 360 0155 Fax +44 121 325 1079 Email sales@crossmorse.com23CD ContentsCatalogue Selection INDEX<strong>Overload</strong> <strong>Protection</strong> <strong>Clutches</strong> :INDEXBACKNEXT

Series CZ Safegard <strong>Overload</strong> ClutchCROSS+MORSEZero backlash <strong>Overload</strong> <strong>Clutches</strong> and Couplings, series CZ,available in 8 different basic types, and 5 basic sizes, for shaftdiameters from 8mm to 60mm; providing <strong>Overload</strong> <strong>Protection</strong>for Torque values from 5Nm to 740Nm.The CZ series Safegard overload clutches were developedto provide a totally backlash free transmission of power witha very responsive overload protection. These compact unitsare directly interchangeable with existing designs in the marketproviding a cost advantage with long reliable service life.Two basic modes of operation are available, the basic CZFSafegard ratchetting design with the driving balls equallyspaced so that clutch can re-engage after a small angle ofrotation, and the Synchron CZY design with the balls unequallyspaced so that clutch can only re-engage after a full revolutionso providing full synchronisation between driver and driven.Responsive overload reaction is obtained by the use of negativefunctioning Disc Springs to apply drive load. In the event of anoverload the spring load actually decreases, allowing fasterdis-engaging of the drive, and minimal pressure on the drivingsurface in the dis-engaged mode, reference diagrams below.Power Transmission SolutionsENGAGED DISENGAGED ENGAGED DISENGAGEDAt Maximum Torque SettingAt Minimum Torque SettingMethod of OperationDuring normal operation the CZ <strong>Overload</strong> Clutch transmitsthe torque from the Hub (1) to the Flange (3) by a numberof hardened steel balls (4) located in pockets in the Hub,and forced into matching seats in the Flange by the DiscSpring (6) applying load to the Pressure Flange (2).In the event that the Driving Torque exceeds the pre-set value,the reaction forces on the Steel Balls exceeds the force appliedby the Pressure Flange, and the Balls start to ride-up out of theirseats in the Flange (3). This action reduces the spring load, soallowing the Balls to quickly come out of their seats, so releasingthe drive. The action of the Balls dis-engaging moves the PressureFlange to the right so activating the stop switch (9).Re-engagement is automatic once the torque level drops below thepre-set value. The Synchron design re-engages only at one angularposition to keep Hub and Flange accurately synchronised at all times.The Disc Springs work only in the negative area of their characteristicsso unscrewing the Adjusting Nut (7) increases the axial load of the Springs,so increasing dis-engaging torque. When desired Torque setting is achieved the Adjusting Nut is locked by the Bolt (8)being screwed into the locking Collar (10).T el +44 121 360 0155 Fax +44 121 325 1079 Email sales@crossmorse.com28CD ContentsCatalogue Selection INDEX<strong>Overload</strong> <strong>Protection</strong> <strong>Clutches</strong> :INDEXBACKNEXT
