SYNTEX® backlash-free overload system

Compact overload clutch

SYNTEX®-NC is a torque-limiting, backlash-free overload system which operates using a form fit. In the event of an overload, a drop in torque to a significantly lower residual torque occurs. The SYNTEX®-NC is a non-load-holding coupling.

Highlights

• Backlash-free and torsionally rigid
• High repeat accuracy and short response times
• Direct mounting of e.g. toothed belt pulleys possible
• Can be combined with ROTEX® GS and TOOLFLEX®
• Functional description

The design of the backlash-free SYNTEX®-NC overload system is based on a spring-pre-tensioned and form-fit ball catch principle which enables a high repeat accuracy and short response times. Disk springs with a degressive spring characteristic curve are used, whose preset preload force decreases during the disengagement procedure. This causes the drive and output to be reliably separated from each other within milliseconds. At the same time, the wear on the components is reduced to a minimum.

The DK version (ratcheting version) re-engages in the subsequent depression every 15 ° in the event of an overload.

The SR version (synchronous version) only re-engages again after one revolution (360 °) in the event of an overload.

Power range

• Overload protection up to 550 Nm
