ABSTRACT:
Multiarc (multi-truss) retaining ring adapted for assembly in a circumferential groove provided for its reception on or in a carrier-member surface, such as that of a shaft, spindle and the like or a housing bore, thereupon to form an artificial machine-element (part) retaining and/or locating shoulder on or in said carrier member, the outer and inner edges of the ring body, rather than being continuous, each comprising the arcuate edges of a plurality of short-length circumferentially spaced-apart arcuate "beams," the inner-edge arcuate "beams" being staggered, i.e. non-radially related, with respect to the outer-edge arcuate "beams" and said outer- and inner-edge "beams" being each trussed by ring-body portions (arms) extending non-radially (divergently) therebetween, the aforesaid arrangement of outer-edge and inner-edge "beams" and ring-body connecting portions of arms or such that the ring body has configuration in plan corresponding to a plurality of serially-connected upright and inverted queen trusses having common connecting arms extending between the outer-edge and inner-edge arcuate "beams" thereof, and the length and inclination of the said connecting arms being such that circumferential stresses acting around the ring body as an incident to its being expanded or compressed (contracted) will cause an elastic circumferential lengthening or compression of the ring body to a significant degree.
