Zero-Max Torq-Tender Overload Safety couplings 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.
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.
These couplings are simple to operate. 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 2- to 3000 in.-lb, these couplings have tamper proof preset torque settings. The precision torque settings do not require costly and potentially risky calibration procedures.
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 in.
They are available in many standard sizes. From the smallest, TT1X (torque ranges 2 to 60 in.-lb) to the largest TT4X (torque ranges 750 to 3000 in.-lb), there are many precision preset factory torque ratings available.
