The positive (ratcheting) torque limiter
SIKUMAT ST is a precision safety device for machines and installations. It operates ratcheting and backlash-free using the ball principle and is intended for compact shaft-mounted applications with an integral cone clamping element and bearing support.
Advantages- Backlash-free operation in both rotation directions
- Compact design with high power density
- Integral ball bearing to support the driven component
- Very high response accuracy due to the ball principle
- Simple, backlash-free shaft fastening with integrated cone clamping element
- Calibrated micro-adjustment of the torque setting, possible even after installation
Function- When the preset limit torque is reached, the SIKUMAT4 ratchets through
- The SIKUMAT4 automatically re-engages once the overload is removed
- Overload can be signalled by a proximity switch to stop the drive or trigger another control function
