Introduction



By precision grinding of Curvic Coupling, there are a big contact area occurred after meshing to be higher hardness of the tooth surface and end therefore by transferring bigger torque to increase the wear-life and be better stability of the production.

Because of the contacting surface of the Curvic coupling is the concave- convex shape, there is the arc surface stress instead of a point or line’s position, so there will not occur the appearance just like the corner chipping , edge breaking, vibration from one way up-warp.

There is the centrifugal force occurred during high rotation speed however as the concave arc tooth can pick up inside to equip with higher rotate speed as well as increase the speed.

The production can center automatic automatically with high precision which can divide the complex massive structure into a few simple parts to be convenient to the designing, manufacturing, assembling and maintaining as well as reducing the weight and the boundary dimension, therefore which was widely used by the aerospace Companies and institutions of Europe and America developed countries.

The application area of XiongMing’s production is as bellow:

1, The precision index location: servo or oil pressure tool turret, rotating table, universal cutter head, robot, soft unit professional machinery equipment etc.

2, High speed huge twist institution, air-turbine motor, locomotive nuke industry pump, centrifuge turbo -compressor, heavy loading helicopter etc.
