Easily removable equipment coupling. Teeth use high-frequency hardening and surface uses chromate plating for high strength. Tooth type uses crowning machining and can be used up to a optimum of 5°. Pilot hole products and shaft hole full products with keyway and tap available
Gear couplings transmit the best quantity of torque and the best quantity of torque in the tiniest diameter of any flexible coupling.
Each coupling includes two hubs with crowned exterior gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted with each other. Gear couplings accommodate angular and axial misalignment by the rocking and sliding of the crowned equipment tooth against the mating sleeve the teeth. Parallel misalignment is usually accommodated by having two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication based on the application form. They are sensitive to lubrication failures but if properly installed and preserved, 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 upon the root, tip and face to articulate Gear Couplings Inner Hub And Ring Gear freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth might help protect devices from damaging loads.
