Rotor Clip Company, Inc., a leading manufacturer in retaining rings, hose clamps and related products has improved upon the method of eliminating endplay-vibration in a pump application. The bearing of an automobile power steering pump was being retained by a threaded nut to eliminate vibration caused by endplay. Additional labor was required to machine complementary threads on the housing so the nut could be installed.
The nut also required a certain torque during installation for each unit, also resulting in increased labor and costs. Endplay vibration is now eliminated by the use of a beveled retaining ring from Rotor Clip.
Machining a simple groove into the application allows the complementary angle of the beveled ring to assume the function of the more costly and cumbersome nut. Once installed, the retaining ring eliminates the need for additional labor to torque the part or machine threads on the housing. Also, the cost of the beveled ring is far less than the nut originally used.
