Easily removable gear coupling. Teeth make use of high-frequency hardening and surface area uses chromate plating for high longevity. Tooth type uses crowning machining and can be used up to a maximum of 5°. Pilot hole items and shaft hole complete products with keyway and tap available
Gear couplings transmit the best amount of torque and the best amount of torque in the tiniest diameter of any flexible coupling.
Each coupling consists of two hubs with crowned exterior equipment teeth. The hubs mesh with two internally splined flanged sleeves that are bolted collectively. Gear couplings accommodate angular and axial misalignment by the rocking and sliding of the crowned equipment teeth against the mating sleeve the teeth. Parallel misalignment is accommodated by having two adjacent hub/sleeve flex points. Gear couplings require periodic lubrication depending on the application form. They are delicate to lubrication failures but if properly installed and maintained, these couplings have a service life of three to five 5 years and in some instances they can last for decades.
Gear Couplings’ triple-crowned teeth are crowned on the main, tip and face to articulate freely and minimize wear caused by misalignment. Through the elimination of tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth can help protect apparatus from damaging loads.
