High accuracy end face circle-arc tooth coupling is usually used for gas engine corona, centrifuge, aero turbine engine

rotor, nuke industry pump, high-speed locomotive bogie hollow shaft, robot joint, high-end tool, major project etc.

Accuracy end face circle-arc tooth coupling possesses the following merits just like special teeth style meshing big square with higher tooth surface hardness and teeth end hardness so that could be longer service life and better stableness. This product can centre automatically with high precision which can transmit bigger torque and fractionalize complicated massive structure into

a few simple structure parts thus to be convenient for designing, making, assembling and servicing to the industrial products and just because of this reason which might be widespread using necessarily. Because of the contact surface between the teeth is concave-convex arc so there was the stress on the surface instead of the stress on the point and lines than there are no status like the collapse of the corner and the side from straight tooth with more perfect stability, in the other side, as the concave arc tooth pulls within so can get more higher speed and increase the speed-up therefore in some developed countries in European and American being put in using widely even there the centrifugal will occur during high rotation speed.
