Torque Limiter TL Selection
If using the Torque Limiter with human transportation or lifting devices, take the necessary precautions with equipment to avoid serious injury or death from falling objects.
- (1) From the machine's strength and load, as well as other information, set the trip torque at the point where it should not go any higher. This torque is the Torque Limiter slip torque.
If the limit value is not clear, calculate the torque based on the rated output power of the motor and the rpm where the torque limiter is installed, and then multiply the result by 1.5 to 2.0 times. This is the Torque Limiter slipping torque. - (2) When determining the size of the torque limiter, make sure that the slip torque is within the range of the rated torque of the torque limiter.
- (3) Using the dimension table, verify that the maximum allowable bore diameter of the Torque Limiter is larger than the installation shaft diameter. If the installation shaft diameter is bigger, use a Torque Limiter one size larger.
- (4) Determine the appropriate bushing length based on the thickness of the center member in the Torque Limiter. Select a bush by referring to the bush length in the dimension table. Use a single bush or a combination of bushes, whichever is longest without exceeding the thickness of the center member.
