Easily removable gear coupling. Teeth use high-frequency hardening and surface area uses chromate plating for high longevity. Tooth type uses crowning machining and can be utilized up to a maximum of 5°. Pilot hole products and shaft hole complete products with keyway and tap available
Gear couplings transmit the highest amount of torque and the highest amount of torque in the tiniest diameter of any flexible coupling.
Each coupling consists of two hubs with crowned exterior Gear Couplings Inner Hub And Ring Gear equipment 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 teeth against the mating sleeve tooth. Parallel misalignment is accommodated by having two adjacent hub/sleeve flex factors. Gear couplings need periodic lubrication depending on the application form. They are sensitive to lubrication failures but if properly installed and managed, 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 encounter to articulate 
freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances,HEPT triple-crown teeth can help protect tools from damaging loads.
