New torque limiters suit high powers and speeds

DSM torque limiters are modular, using three to nine spring-loaded cartridges that press a steel ball into a hardened seat. Under normal conditions the connection is backlash-free. On overload the balls ride out of the seat, pushing back the springs to a detent position where there is no longer any drive torque between input and output. The overload results in axial movement which can be sensed with a proximity switch to trigger an alarm. Subsequent re-engagement is a manual process. The release torque can be pre-set and adjusted using calibration markings on the cartridges.

In the UK sales and technical support for the DSM torque limiters is available from Techdrives. They can be mounting with a chain or belt connection suiting offset drives, or supplied with a flexible coupling for in-line mounting. DSM torque limiters suit shafts up to 140mm diameter and are maintenance free.
