Easily removable gear coupling. Teeth use high-frequency hardening and surface uses chromate plating for high longevity. Tooth type uses crowning machining and can be used up to a optimum of 5°. Pilot hole products and shaft hole comprehensive products with keyway and tap available
Gear couplings transmit the highest amount of torque and the highest quantity of torque in the smallest diameter of any flexible coupling.
Each coupling contains two hubs with crowned Gear Couplings Inner Hub And Ring Gear external gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted together. Gear couplings support angular and axial misalignment by the rocking and sliding of the crowned gear teeth against the mating sleeve tooth. Parallel misalignment can be accommodated by having two adjacent hub/sleeve flex points. Gear couplings require periodic lubrication depending on the application form. They are sensitive to lubrication failures but if correctly installed and maintained, these couplings have a service life of three to five 5 years and in some cases 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. By eliminating tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth might help protect products from damaging loads.
