Easily removable gear coupling. Teeth use high-frequency hardening and surface uses chromate plating for high strength. Tooth type uses crowning machining and can be utilized up to a optimum of 5°. Pilot hole products and shaft hole finish items with keyway and tap available
Gear couplings transmit the highest amount of torque and the highest quantity of torque in the smallest diameter of any flexible coupling.
Each coupling contains two hubs with crowned exterior gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted jointly. Gear couplings accommodate angular and axial misalignment by the rocking and sliding of the crowned gear the teeth against the mating sleeve teeth. Parallel misalignment is usually accommodated by having two adjacent hub/sleeve flex points. Gear couplings need periodic lubrication depending on the application form. They are delicate to lubrication failures but if properly installed and managed, these couplings have something life of 3 to 5 5 years and in some instances they can last for decades.
Gear Couplings’ Gear Couplings Inner Hub And Ring Gear triple-crowned teeth are crowned upon the main, 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 products from damaging loads.
