Coupling, half, gear, FST type, FST130, 22000 Nm, 4350 RPM, esco.

The F type gear coupling is a torsionally rigid grease filled coupling consisting of two hubs with external multicrown and two flanged sleeves with straight internal teeth. The flanged sleeves are bolted together with high strength corrosion protected fitted bolts and nuts. The sleeve is at the opposite side of the flange executed with an endcap (internal for small and screwed for big size couplings) in which the o-ring is located for sealing purposes. The gear coupling has been designed to transmit the torque between these two flanges through friction avoiding fretting corrosion between these faces. The teeth of hub and sleeve are continuously in contact with each other and have been designed with the necessary backlash to accommodate angular, parallel and axial misalignment within their misalignment capacity.
