Abstract
Abstract A flexible coupling including a pair of juxtaposed coupling members and a flexible torque-transmitting member for transmitting torques from one of said pair of coupling members to the other is provided with intermediate auxiliary torquetransmitting layers having a high coefficient of friction to increase the strength of the frictional engagement of cooperating parts of the coupling. The above layers are formed by spray deposits of metal particles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
In a flexible coupling including a pair of juxtaposed coupling members each having a non-planar torque-transmitting surface, a flexible torque-transmitting member for transmitting torques from one of said pair of coupling members to the other of said pair of coupling members, and a pair of clamping means each having a non-planar torque-transmitting surface engaging portions of said torque-transmitting member for clamping said portions of said torque-transmitting member against said torque-transmitting surface of each of said pair of coupling members, the novel feature consisting in that said torque-transmitting surface of each of said pair of coupling members is provided with an intermediate torque-transmitting relatively thin integral sprayed-on metal overlay and in that said torque-transmitting surface of each of said pair of clamping means is provided with a relatively thin integral sprayed-on metal overlay.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
104 words
A flexible coupling include a flexible torque-transmitting member substantially U-shaped in cross-section and having a pair of flanges, a pair of coupling members having non-planar clamping surfaces engaging axially inner surface elements of said pair of flanges of said torque-transmitting member, each of said clamping surfaces of said pair of coupling members being provided with a sprayed-on metal deposit, and a pair of clamping members having non-planar clamping surfaces engaging and screwed against axially outer surface elements of said pair of flanges of said torque-transmitting member, each of said clamping surfaces of said pair of clamping members being provided with a sprayed-on metal deposit.
