Overload safety couplings



Zero-Max Torq-Tender Overload Safety couplings are designed to protect critical rotating power transmission components from torque overloads. Torq-Tenders serve both as a safety device and as a coupling in a power transmission system.

Protecting motor and drive systems from jam-ups and excessive overloading, Torq-Tenders can be manufactured for systems requiring frequent washdowns, such as food manufacturing and packaging applications. With the addition of an O-ring seal and simple housing modifications, Torq-Tenders resist contamination and are easily washed, the company says.

How does it work? When a power transmission system’s load exceeds the preset precision-tempered torque spring rating, the Torq-Tender’s drive mechanism pivots out of an engagement slot, disengaging the prime mover from the load, providing overload protection.

When the overload is removed and the speed is reduced, the Torq-Tender resets itself automatically. The single position re-engagement point maintains equipment timing and positioning. Available in torque ranges from two to 3,000 in-lbs., Torq-Tenders provide tamper-proof preset torque settings. As a coupling, the Torq-Tender can handle up to 1.5 degrees of angular misalignment and a maximum parallel misalignment of 0.005 to 0.015 inch.
