Overload coupling ratchet design DK:Any engagement after an overload. After eliminating the overload, the balls re-engage automatically with the next following ball indentation.Overload coupling synchronous design SR:Synchronous engagement after an overload. After eliminating the overload, the balls re-engage automatically after a rotation of 360°. Driving and driven side are always placed in the same position to each other. Other degrees of reengagement, e. g. 180°, are possible.
Overload coupling idle rotation versionWhen reaching the torque set the overload coupling releases. Driving and driven side keep separated due to the idle rotation mechanism, the resulting flywheel mass can slow down in idle state. After eliminating the overload, the coupling can be re-engaged. Re-engagement takes place either manually or via a device.Overload coupling fail-safe design SGR:The fail-safe design is purely intended for torque measurement without any slipping operation. In case of overload a signal is generated by a limit switch along with mechanical separation of driving and driven side = ratcheting is not possible.
