Constant Retaining Rings
Constant section retaining rings feature a uniform, constant section. This means that the material used to make the ring is the same width at any point along the circumference of the ring. These cost less than tapered and spiral retaining rings and provide only three point contact with the groove as shown below.
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.
