Easily removable equipment coupling. Teeth make use of high-frequency hardening and surface uses chromate plating for high sturdiness. Tooth type uses crowning machining and can be utilized up to a optimum of 5°. Pilot hole items and shaft hole full items with keyway and tap available
Gear couplings transmit the highest amount of torque and the best quantity of torque in the tiniest diameter of any Gear Couplings Inner Hub And Ring Gear flexible coupling.
Each coupling includes two hubs with crowned exterior gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted collectively. Gear couplings support angular and axial misalignment by the rocking and sliding of the crowned equipment teeth against the mating sleeve teeth. Parallel misalignment is definitely 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 preserved, 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. By eliminating tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth can help protect tools from damaging loads.
