KTR-SI FRE with ROTEX®

Setting the release torque of the overload coupling:

In order to set the coupling to the requested release torque, a defined pre-stress is generated on the disk springs in each idle rotation element via the setting nut. The number of idle rotation elements varies depending on the release torque specified. If requested, the coupling can be preset by the manufacturer. It is also possible to adapt the coupling individually when in place.

Re-engagement of idle rotation elements of the safety coupling:

After eliminating the overload, driving and driven side are aligned to each other first. By means of a plastic hammer or a tyre lever the idle rotation elements are manually re-engaged. Re-engagement can be loudly heard. The overload coupling is ready for use again.

The core of the overload couplings (safety couplings) is formed by the idle rotation elements. They uncouple the driving and driven side in case of overload while protecting the drive train from damages. After eliminating the overload, the idle rotation segments are manually re-engaged so that the drive is released again. In order to set the coupling to the requested release torque, a defined pre-stress is generated on the disk springs in each idle rotation element via the setting nut. The number of idle rotation elements within the overload coupling varies depending on the release torque specified. If requested, the overload coupling can be preset by the manufacturer. It is also possible to adapt the safety coupling when in place.
