What are the advantages of a mechanical torque limiter?

Machine torque overloads can arise from various causes. Regardless of the source, R+W torque limiter couplings offer a swift and dependable disconnection between driving and driven components whenever torque exceeds a predetermined threshold. This helps prevent equipment damage, operator injury, and costly downtime.

Operating on a spring-loaded ball-detent mechanism, R+W torque limiter couplings function as overload breakaway devices. They ensure rigid, zero-backlash power transmission under normal conditions, but when torque surpasses the set limit, the balls disengage from their detents, effectively disconnecting the driveline.

The spring-loaded ball-detent system provides several advantages, including:

• Fast and precise disengagement to protect machinery from excessive torque loads.

• Zero-backlash performance, ensuring high precision in motion control applications.

• Automatic re-engagement in some designs, reducing the need for manual resetting and minimizing downtime.

• Compact and lightweight construction, making it suitable for applications where space and weight constraints are critical.

• Consistent torque limitation with minimal wear, ensuring long service life and reliability.
