Abstract
The clamp apparatus transmits torque forces between a shaft and a hub. The clamp apparatus comprises conical rings, each having a conical surface together with a cylindrical inner or outer circumferential surface. The conical rings are drawn together by axial straining screws, thereby radially expending the clamp apparatus. Surface channels are provided on at least one of the conical surfaces into which a flowable lubricant may be forced under high pressure.
Claims7
A method of clamping elements together which transmits torque forces between an inner structural element having a cylindrical outer circumferential surface and an outer structural element having a cylindrical inner circumferential surface, said method comprising:
- resting a first conical ring having a cylindrical outer surface against an inner circumferential surface of the outer structural element, said first conical ring having a sloping conical inner surface;
- cooperating a second conical ring with said first ring by resting said second conical ring having a cylindrical inner surface against an outer circumferential surface of the inner structural element and a sloping conical outer surface complementary to said sloping conical inner surface;
- drawing at least one of said conical rings axially relative to each other such that said sloping conical surfaces ride along each other and said rings exerting radical clamping forces while sliding over the sloping conical inner and outer surfaces;
- placing a plurality of surface channels with a small cross section formed on at least one of said surfaces;
- connecting said surface channels with a source of a flowable lubricant under a high pressure when said conical rings are drawn axially relative to each other for reducing friction during clamping.
