KTR-SI FRE Idle rotation overload 联轴器

The core of the 过载联轴器 (safety 联轴器) 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 rotation segments are manually re-engaged so that the drive is released again. In order to set the 联轴器 to the requested release 扭矩, 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 联轴器 varies depending on the release 扭矩 specified. If requested, the overload 联轴器 can be preset by the manufacturer.
