Gear Couplings Inner Hub and ring gear
Easily removable gear coupling. Teeth use high-frequency hardening and surface uses chromate plating for high durability. Tooth type uses crowning machining and can be used 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 smallest diameter of any flexible coupling.
Each coupling consists of two hubs with crowned external 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 gear teeth against the mating sleeve teeth. Parallel misalignment is accommodated by having two adjacent hub/sleeve flex points. Gear couplings require periodic lubrication depending on the application. They are sensitive to lubrication failures but if properly installed and maintained, these couplings have a service life of 3 to 5 years and in some cases they can last for decades.
