ROTOR CLIP CAN CREATE SPECIAL DESIGNS TO MEET YOUR UNIQUE APPLICATIONS!
Rotor Clip Engineers can work with customers to produce a special retaining ring to accommodate their unique applications. Here is an example.
A customer was looking for a retaining ring to take up endplay and eliminate unwanted noise and vibration in an assembly. The customer decided on an external beveled retaining ring
Beveled retaining rings are similar in construction to the standard internal and external types, except the groove-engaging edge is beveled to a 15° angle. (The bevel is located around the outer circumference of the internal rings, and around the inner circumference of the external rings.) ...
Beveled retaining rings are similar in construction to the standard internal and external types, except the groove-engaging edge is beveled to a 15° angle. (The bevel is located around the outer circumference of the internal rings, and around the inner circumference of the external rings.)
The groove is machined with a corresponding 15° bevel on the load- bearing groove wall. When a beveled ring is installed in the groove, it acts as a wedge between the outer groove wall and the part being retained. The rings spring action causes the fastener to seat more deeply in the groove and compensate for the endplay.
However this customer had a unique problem: the beveled ring had to fit over a larger diameter shaft than the ring could accommodate. The ring would be stretched beyond its elastic limit when installed and take a permanent set, which meant the ring would not return to its original size and grip the groove properly. This would have certainly led to the failure of the application.
Rotor Clip engineers deigned a special beveled ring (Figure 2). This design allowed the ring to be installed over the larger shaft without taking a permanent set, ensuring its proper functioning in the application.

Technical Considerations for the Selection of Retaining Rings
Design engineers are challenged daily to come up with economical designs that reduce weight, size, raw materials, and labor. This competitive mandate affects every facet of the design, including the fasteners needed to hold components in place. One style of non-threaded fastener that has been widely used to accomplish these goals is the retaining ring. Knowing which ring to use in a given fastening situation can greatly contribute to the overall effectiveness and economy of a design.
Calculating Endplay Take-Up for Beveled Retaining Rings
The article discusses how beveled retaining rings are the obvious choice in high speed production over shims and washers. The article is broken down to show how the retaining rings are designed, calculated and manufactured for maximum endplay take up while still being cost effective for both consumer and manufacturer.
