Table of Contents◗FUNCTION EXAMPLES“Air Champ” ®ACCURATE POSITIONING:A brake or clutch/brakeprovides very precise andrepeatable stopping.Tight tolerances are held incut-to-length systems, fillingoperations, and machiningcycles, with limit switches,photo electric cells orproximity switches accuratelysense position.◗ SELECTION CONSIDERATIONS:Transmitted horsepowerRPMTorque◗ EXAMPLEA clutch-brake is necessary to accuratelyposition a turntable carrying bins whichrotate under a feeder head. The feederhead dumps a predetermined amount ofmaterial into the bins at regular, timedintervals.The motor is a 5 horsepower, 1800 RPM,184TC frame.D01133438◗ “AIR CHAMP”PRODUCT CONSIDERATIONS:S, T, TSE450–1400CALIPER BRAKESDB, BC, BD,VC500, SPC◗ UNIT SELECTED:A modular MDB-1125 based on themotor frame size only. THe MDB-1125consists of an MBU=1125,Product Number 935200and an MDU-1125,Product Number 935100.◗ CONTROL CIRCUITA proximity switch energizes the 4-wayclutch-brake control circuit.4-WAY SINGLE SOLENOID SPOOL CON-TROL INTERNAL PILOTED — N.C.

Table of ContentsOVERLOAD PROTECTION:Protects expensive machinery orproducts from jam-ups and overloading.Air <strong>clutches</strong> excel at this functionbecause (1) torque level is easilyand accurately set by air pressure,and (2) torque to start the load(often two to three times thedesired protective torque) iscompensated for a dual pressurecontrol circuit.“Air Champ” ®◗ SELECTION CONSIDERATIONS:Transmitted horsepowerRPM at the clutchTorque◗ EXAMPLEA device is required to provide overloadprotection for the drive componentswhich include a 1/2 horsepower, 900RPM motor and a 100:1 reducer. Thisdrive is powering a continually runningconveyor which is feeding parts onto aheat treating oven.The unit is mounted on the reducer outputshaft which rotates at 9 RPM.DO2135445This application is classified as an occasionalstart. Select a Torque Limiterbased on the transmitted horsepowerand RPM.◗ “AIR CHAMP”D01135444FUNCTION EXAMPLESPRODUCT CONSIDERATIONS:BW–XHWF–450L–600M–800H–1000MODULAR CLUTCHMDO625–1375TORQUE LIMITERTorque = 63000(.5) = 3500 in. lbs.9◗ UNIT SELECTED:A TL40-A, Torque Limiter,Product Number 801522.◗ CONTROL CIRCUITA dual pressure circuit is used to provideD0413544765 PSI for starting the conveyor and 30PSI running pressure. See diagrampage 111.D05135448If and overload occurs, the TorqueLimiter Interfaces separate, moving thecylinder to the outer position. This movementis detected by the limit Switch,which de-energizes the 3-way Air InletMount Solenoid Valve, thus exhaustingair to the Torque Limiter. Internal springsprovide assistance for total TorqueLimiter release.All of the drive components down to themotor are protected from an overload.D03135446DPC9T–15TDFE, QFE1150–2500379
