Easily removable gear coupling. Teeth use high-frequency Gear Couplings Inner Hub And Ring Gear hardening and surface uses chromate plating for high durability. Tooth type uses crowning machining and can be used up to a maximum of 5°. Pilot hole items and shaft hole total items with keyway and tap available
Gear couplings transmit the best amount of torque and the highest quantity of torque in the smallest diameter of any flexible coupling.
Each coupling includes two hubs with crowned external equipment 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 teeth. Parallel misalignment is definitely accommodated by having two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication depending on 
the application. They are delicate to lubrication failures but if correctly installed and taken care of, these couplings have a service life of 3 to 5 5 years and in some cases they can last for many years.
Gear Couplings’ triple-crowned teeth are crowned upon the root, tip and face to articulate freely and minimize wear due to misalignment. Through the elimination of tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth can help protect products from damaging loads.
