Protect machines from overload damage

KBK overload clutches mechanically disconnect both parts of the driveline if the torque is exceeded. This prevents or at least significantly reduces overloads and the resulting damage to the drive.

As users can freely select the release torque and set it precisely on the clutch, the machine performance can be optimally utilized. KBK uses disk springs with a degressive characteristic curve and balls as locking elements for the safety clutches. This design means that torque transmission is interrupted within milliseconds when the release torque is reached, reducing the risk of damage to a minimum. The product range includes overload clutches with roller bearings (0.2 to 1,400 Nm), plain bearings (0.2 to 500 Nm), metal bellows (0.2 to 1,400 Nm) and gear rims (3 to 500 Nm). In terms of functional systems, there is a choice between overload clutches with synchronous engagement, ratchet engagement and disengagement as well as a locked version. Clutches with synchronous engagement automatically re-engage once the overload has been removed, locked safety clutches are mechanically locked a few degrees after disengagement and disengaging models permanently separate the input and output lines from each other without torque.
