Sikumat SU.pdfSIKUMAT® SU … Synchronous Ratcheting – Backlash free – with balls
The torque is transmitted via balls that are pressed by Belleville springs into v-shaped grooves. The grooves are arranged axially on the output side and radially on the input side, which means that torque can be transmitted backlash-free in both directions of rotation. When the preset limit torque has been reached, the groove-ring is displaced. Due to the unsymmetrical division of the grooves, re-engagement is effected synchronously after 360°, as soon as the overload has been eliminated. The negative characteristic disc springs give extremely fast, accurate and consistent overload protection.
Advantages
- Backlash free in both directions of rotation
- Compact design
- Integral ball bearing for supporting the component to be connected
- Very high response accuracy through the ball principle
- Simple and backlash-free fastening onto shaft with integral cone clamping element
- Calibrated micro-adjustment of torque setting possible, even post-installation
Function
- When the preset limit torque has been reached the SIKUMAT® ratchets through.
- Following elimination of overload automatic synchronous re-engagement of the SIKUMAT® to the starting position after 360°.
- The overload can be indicated by a proximity switch. This means that the drive can be switched off immediately or another control function can be activated.
