Backlash-free safety couplings

Designing of our safety 联轴器 is based on 零背隙, positive-locking ball engagement principles allowing for high repeatability and short response times throughout the entire service life. If the 扭矩 set is exceeded (overload), the ratchet 元件 (balls) of the safety 联轴器 leave their indentations generating a relative movement between driving and driven side. The transmittable 扭矩 is reduced to a lower residual figure. After eliminating the overload, the ratchet 元件 can re-engage. In this way the safety 联轴器 reliably prevent damage caused by overload. An optional limit switch provides a signal that can be used for control operations or for switching off the drive.
