Easily removable equipment coupling. Teeth make use of high-frequency hardening and surface uses chromate plating for high durability. Tooth type uses crowning machining and can be utilized up to a optimum of 5°. Pilot hole items and shaft hole finish products with keyway and tap available
Gear couplings transmit the highest quantity of torque and the best amount 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 together. Gear couplings accommodate angular and axial misalignment by the rocking and sliding of the crowned equipment tooth 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 form. They are sensitive to lubrication failures but if properly installed and taken care of, these couplings have something life of 3 to 5 5 years and in some instances they can last for many years.
Gear Couplings’ triple-crowned teeth are crowned on the main, tip and encounter to articulate freely and minimize wear due to misalignment. Through the elimination of tip-loading while Gear Couplings Inner Hub And Ring Gear reducing backlash and radial clearances,HEPT triple-crown teeth can help protect equipment from damaging loads.
