Extended Line-up

Ideal integral backstop The BR-HT series Torque Limiter model is a combination of a centrifugal lift-off cam clutch and a torque limiter function in case of unbalanced load in multi derives. The BR-HT series Tension Release model has a mechanical on-off system installed with the torque limiter function. Both models are ideal for inclined belt conveyors for safety and ease of maintenance. Application example for Torque limiter modal (Dual drive inclined belt conveyor) Features 1.Sharing of the backstop load in case of an unbalanced situation due to the backlash of gears and couplings. 2.Reduce...

1.We recommend using shaft tolerances of h6 or h7 for Cam Clutch installation. 2.Use ISO R773/DIN 6885.1 Parallel key or DIN6885.3. Ensure that the key does not move in the keyway. A loose key will damage the Cam Clutch. 3.Resolve Socket bolts and Seal washers, and then remove the Cover B with O-ring. 4.Total Indicator Reading (T.I.R.) does not exceed the value shown in right figure. 5.Install Flange A to the housing prepared by the customer. The bolts connecting for Flange A must comply with a strength class of 8.8 or 10.9 and need torque tightening to the following table using a torque tightening...

Selection Procedure 1.To calculate the setting torque, please apply 20% higher than maximum backstopping torque per one clutch. Maximum backstopping torque should include overload conditions. 2.Select the proper clutch on page 3 or 4 which satisfies the calculated setting torque. 3.Check Innerrace overrunning speed and bore size. FOR TENSION RELEASE MODEL BR-HT-TR Tension release function releases the backstop. It is absolutely necessary to pay attention on these operations. When the load is left on a coveyor, it would reverse. 1. Releasing back stopping torque (1) Make a match mark on Hexagon...
