Groove depth: The height of the groove's wall. Retained parts may have a radius or chamfer where they contact the retaining ring. For example, retaining ring grooves may have a small radius where the bottom and the wall of the groove meet. Radius or chamfer: A curve or transitional edge at the interface between two edges. Side clearance: The gap between the retained part and the wall of the housing.Įdge margin: The distance between the end of a shaft or housing and the groove into which the ring is fitted.įree diameter: The diameter of a retaining ring before it has been installed. Housing diameter: The diameter of the housing containing the retained part. Both rings and grooves have a maximum thrust load capacity that depends on the materials used, size, and other factors. They are the forces a retaining ring absorbs to keep the retained part in place. Thrust load capacity: Thrust loads act along the axis of a housing or shaft. The parts of the ring’s circumference surrounding the gap are called free ends. Lugs allow a tool to compress or expand the ring during installation.įree end: Many retaining rings feature a gap to allow for expansion or compression. Lug: A lug is the widened section of an axially installed retaining ring, usually featuring holes or notches for tool attachment. This category includes round wire rings and square wire rings, among others. This category includes snap rings and housing rings.Ĭonstant section retaining ring: A ring in which the section is the same around its circumference. Tapered retaining ring: A ring with a section (see below) of varying depth. This category includes housing rings, snap rings, and spiral rings. This category includes E-clips, snap rings, and poodle clips.Īxially installed retaining ring: A ring installed along the axis of a shaft or housing. Radially installed retaining ring : A ring installed by clipping it over the outside of a shaft. We’ll go into greater depth about these in the next section, but first, it is helpful to understand some of the language used to describe retaining rings. Multiple factors impact the design of a machine assembly that uses retaining rings, including how the ring will be installed, the measurement and machining of the groove, and the relation of the ring to the housing and the retained part. The most widely used of these rings are snap rings, housing rings, and spiral rings, all of which fit into a machined groove on a shaft or in a bore, but there are many other varieties, each with a specific role. Retaining rings reduce manufacturing complexity and cost, providing an easy-to-install alternative to a machined shoulder. Retaining rings are a broad category of components used to create an internal or external shoulder to retain parts in housings and on shafts.
