w h e n f u l l p o w e r i s n e e d e dPlanox ® - Friction ClutchesFig. 2Type PPMFig. 1Type PMDESCH Planox ® -clutches are engageable/disengageable dry-friction clutcheswhich transmit the torque by friction.These clutches permit rapid accelerationof the driven machines or machinerygroups as well as safe torque transmission.Machines connected by frictionclutches are protected against damagewhich can occur by peak torques duringoperation or during the engaging/ disengagingprocess. In the case of themechanically actuated Planox ® -clutchthe lever moves the sleeve (8) whichpresses the pressure ring (7) with theadjusting ring (6) and dished spring(29) against the pressure plate by meansof three clutch levers (9). The torque,normally transmitted via the toothedring (1) to the friction discs (27), is thentransmitted by friction via the innerdiscs (3) and the pressure plate (4) tothe hub ( 2). One friction surface of theclutch forms a unit with the hub. As allthe forces inside the clutch cancel eachother when the clutch is engaged, additionalaxial loading of the adjacent shaftbearings is excluded. The built-in discsprings provide the following specialadvantages:1. Limitation of the peak torque duringthe engaging process2. Torque accurately set and limited.3. Automatic re-adjustment over a relativelylarge wear and thus low maintenance.Fig. 3 shows the torque curve of aclutch with and without dished springs.When a correctly dimensioned clutchis engaged, there is at the same timean overload protection feature againstpeak torques coming form the drivingor driven machines.Fig. 3Fig. 4 illustrates that the torque curve ofthe clutches in the range of the automaticre-adjustment of max. 1 mm is very flat.This favourable characteristic of thecurve cannot be achieved by flexiblelevers or spiral springs.Fig. 4The Planox ®friction clutchwith bellhousing and outer bearing has beendeveloped to be fitted to diesel engines.It is available as mechanically, pneumaticallyor hydraulically actuatedclutch. The complete clutch includingbearings is accommodated in a bellhousing which forms a unit with theengine after being installed. This designis a technical and economic success.The powerfully dimensioned bearingsof the output shaft in the clutch housingpermit power take-off via flexiblecouplings or pulleys. The admissibleradial loads on the output shaft endare shown as a function of speed inthe table on page 8. The flywheel andflywheel housing connections complywith the Ameican SAE standards J 617and J 621. The connecting dimensionsof the flywheel meet the Americanstandard J 620d and the VDMA standardsheet 24 380. We have adapted theconnecting dimensions of our clutchesand bell housings to these standards.Assuming the SAE standards areobserved on the engines, the Planox ® -clutches can be mounted without theuse of spacer rings. The clutch sizes fordiesel engines were selected in collabortationwith the engine manufacturers.In the event of frequent engaging/disengagingor large masses to be accelerateda check of the thermal loading of theclutch must be made (see page 13).

Selection of clutch size accordingto mechanical loadThe torque values T S= engaging torque ofclutch (dyn.) in Nm are listed in the tables.The torque values stated can be transmittedunder constant loading. However, in the eventof varying load conditions the correspondingsafety factors „S“ must be taken into consideration:These can be found in the tables.Peak torques can occur during engagementor operation dependant on the types ofmachines being coupled. The clutch sizeshould always be orientated to the maximumload.One should distinguish between the followingcases:1. The clutch has to accelerate an insignificantmass such that nominal torque (T K) isequal to the clutch moment (T S) with regardto operating factor „S“.T K= T L· S T S[1]T K= P n· 9550 · S (Nm) [2]2. The clutch has to transmit a load torque(T L) during the engagement process itself andaccelerate a large mass.T K= T L+ T a T S[3]T K= P nSelection of clutch size according to mechanical load and friction workBesides ensuring optimum torque transmission the friction clutch must also be able to withstandthe heat generated during the engeagement process.Friction work per engagement during a on-load startQ present.

In case if power is taken from the driving machine already during acceleration, thefriction work increases in relation of the clutch torque to the load torque.Clutches for use with driving engines anddriven machines with a high coefficient ofcyclic load variation (i.e. piston engines)should be designed according to the specifictorque requirements (a torque diagram ofthe application may help).
