Catalog excerpts
The safety coupling modular system consists of three standard series, as well as several special solutions for nearly every conceivable application. Various attachments can be fit to the safety mechanism, depending on the application. For indirect drives, pulley, gear, or flange connection is available. For direct drives, the safety mechanism is connected to a metal bellows or elastomer coupling. The most important criteria for selection are the required disengagement torque, torsional stiffness, shaft diameters, assembly conditions, and shaft misalignment. safety mechanism ✓ pulleys ✓...
Open the catalog to page 2Safety Couplings I Technical Information JAKOB safety couplings are designed as nominal break points or as overload protection in a direct or indirect drive train. The heart of the safety coupling is a highly precise, sturdy disengagement mechanism with steel balls as spring loaded positive locking elements. The drive torque is guided into the centrally arranged hub via a frictional, backlash-free radial clamping hub or conical bush connection. The hub is designed as a ball cage and serves for fitting the flange ring and the shift disk. Special cup springs press the balls over the shift...
Open the catalog to page 3Safety Couplings I Adjusting the Disengagement Torque The disengagement torque generally is between 40% and 100% of the nominal torque of the coupling and is adjustable steplessly. If the customer does not specify a setting value, it is set at the maximum torque (nominal torque). The set, static disengagement torque can be adjusted (on the machine) at a later date by turning the adjusting nut with a pin wrench if needed. Adjusting nuts are provided with a user friendly scale: the disengagement torque, and the reference marks for Tmin and Tmax are engraved on the face side of the adjusting...
