Easily removable equipment coupling. Teeth make use of high-frequency hardening and surface area 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 finish items with keyway and tap available
Gear couplings transmit the highest quantity of torque and the best quantity of torque in the smallest diameter of any flexible coupling.
Each coupling includes 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 gear teeth against the mating sleeve the teeth. Parallel misalignment is definitely accommodated by having two adjacent hub/sleeve flex factors. Gear couplings require periodic lubrication based on the application. They are delicate to lubrication failures but if correctly installed and taken care of, 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 on the root, 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 might help protect gear from damaging loads.
