■ Overrunning ■ Indexing ■ Backstop Clutch used in this application allows overrunning of large inertia loads upon stopping and prevents backdriving damage of drive system. In the process, an electric motor and geared motor will be involved, through a single shaft connection to drive the machine. Essentially, implementing a low speed geared motor engages clutch whereas electric motor results in overrunning. In this application, clutch is used to convert reciprocating linear motion to incremental rotary motion for conveyor or material feed application. A suitable application example is the feeding roller. Clutch is intact onto the roller and torque arm connected to clutch. They transform reciprocal motion into intermittent rotation. Clutch is used to back-stop (prevent reverse rotation) incline conveyor in material handling application. With the outer race anchored to a stationary postion, inner race can freely overrun in one direction of rotation. This prevents revervse rotation by automatic engagement of clutch. ● Overrun freely in one direction ● Reverse rotation prevented by automatic engagement of clutch The Ratchet Type Able to see operation of clutch Low durability High noise pollution The Roller Type Ease on manufacturing Low efficiency rate under high speed performance The Cam type High speed performance Back rash protection High precision Advantage : Disadvantage : Advantage : Disadvantage : Advantage : Disadvantage : (1) Using the formula below, calculate the torque of cam clutch T = 9550 x kW (2) Conclude operation mode Overrunning, indexing, backstopping (3) Conclude service factor Refer to table 1(a) and 1(b) (4) Calculate design torque Torque x Sevice Factor (5) Calculate bore size (6) Conclude the max. overrunning speed and cycle time of operation (7) Clutch selection vary by: (a) Design torque (b) Bore size (c) Mode of operation (d) max. overrunning speed (8) Indicate name of model, bore size and direction of inner race drive (oil reservoir and clutch type) ● Table 1(a) For Overrunning S.F 1 - 1.5 1.5 -2.5 2 - 3 4 - 6 ● Table 1(b) For Indexing S.F 1.56 - 2 2 - 3 2 - 3 3 - 4 More than 150 θ < 90º Less than 150 θ ≥ 90º More than 150 θ ≥ 90º Shock load Heavy shock load Load cycle / minute Degree / Load cycle Less than 150 θ < 90º Selection Procedure n² Service Factor Load type No shock load Moderate shock load Calculation of torque Belt Conveyor : Legend : 1.

Maximum load and greater torque capacity Cams made with special alloy steel provides maximum load transmitting members per given diameter. Results in greater torque capacity than other clutches. 2. Longer life shell Roller clutch abrasion of inner raceway occurs at same point of roller clutch lands. Dimpling of cam clutches are distributed around inner raceway, not concentrated. Hence there is assurance on long wear resistance and longer life shell. 3. High precision and silent operation Cam clutch has more load bearing points as there are constant changing contact point on both races. These has high precision without backlash and silent operation. Pre-lubricated with grease ( BS30K - BS135K ) No lubrication maintenance required. ( Special grease for low temperature: below -10 ºC ) Grease lubricated type ( BS160K - BS350K ) Use four plugs on clutch outer race for grease fill, level checked and drained. For grease level check, detach plugs and pour grease through grease filter hole (top) until grease flows out from level check hole (middle), then attach plugs and screw tightly. Grease to be added on 3 months interval after initial grease fill. Change whole grease at six months interval. When draining old grease, clean inside of clutch and fill up the clutch with new grease. Oil-lubricated oil reservior type ( BS160RK - BS350RK ) Detach oil plug installed on oil reservoir and pour oil into oil reservoir up till blue line of oil gage. Regular check is essential to maintain that oil level remains above red line of oil gage. Oil should be completely replaced once a year to ensure longer life performance of cam clutch.
