Safety clutches
Avoid downtimes due to overloading
Safety is a particularly important requirement for large systems. Downtimes caused by overloads can quickly become expensive. This is where R+W safety clutches can help.
Wear-free and robust mechanical connecting elements ensure safe, fast and reliable separation between the input and output sides. R+W has years of experience and expertise in design.
Safety clutches are used in many different areas of mechanical engineering. In the event of an overload, they guarantee reliable separation between the input and output sides and ensure precise torque limitation. Safe and fast overload protection is essential, especially for large and heavy systems used in applications such as rolling mills, wind turbines, shovel excavators, extruders, steelworks, shredders and tunnel boring machines, as damage to components of these dimensions can result in expensive repairs or cause a complete system shutdown. Machine safety is therefore the be-all and end-all in a crash situation.
A question of milliseconds
All mechanical safety clutches from R+W work according to a spring-loaded ball detent principle and serve as an emergency stop element for machines. ST series industrial safety clutches transmit torques of 200 to 250,000 Nm even in the standard version in indirect and direct drives. They can be set to the required torque at the factory and can also be adapted to changing requirements. Thanks to the variable installation options, a safety clutch can also be used precisely where the probability of an overload is greatest in the drive train.
