Easily removable gear coupling. Teeth make use of high-frequency hardening and Gear Couplings Inner Hub And Ring Gear surface uses chromate plating for high longevity. Tooth type uses crowning machining and can be utilized up to a maximum of 5°. Pilot hole products and shaft hole comprehensive products with keyway and tap available
Gear couplings transmit the highest quantity of torque and the highest amount of torque in the smallest 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 with each other. Gear couplings support angular and axial misalignment by the rocking and sliding of the crowned equipment teeth against the mating sleeve tooth. Parallel misalignment is usually accommodated by having two adjacent hub/sleeve flex factors. Gear couplings require periodic lubrication depending on the application. They are sensitive to lubrication failures but if correctly installed and managed, these couplings have a service life of three to five 5 years and in some cases they can last for many years.
Gear Couplings’ triple-crowned teeth are crowned upon the main, tip and encounter 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 tools from damaging loads.
