Torque limiting couplings from Voith protect all components in the driveline, allowing your equipment to work at a maximum level. In the event of a catastrophically high torque occurrence, the couplings interrupt the power flow in the driveline. This means that consequential damage and production downtime remain at a minimum. Special designs provide additional advantages to the production process.
The main part of a SafeSet consists of a twin-walled pressure sleeve. Subsequently a pressure cavity is created inside the coupling. By pressurizing oil in the pressure sleeve, it will compress around the shaft and a perfect defined friction grip is created. In an overload situation, when the set torque is exceeded, the SafeSet releases instantly and the shear tube shears off.
The immediate reaction saves the driveline from serious damage and the coupling rotates freely on the bearings until standstill. The sheared shear tube is fast replaced and the coupling is re-pressurized, so that the drive system can go into operation again.
