Abstract:
A retaining ring comprising:a pair of arcuate interlocking members, each arcuate interlocking member having a first end, a second end, an inner wall and an outer wall;the outer wall having a first surface and the inner wall having a second surface thereby defining a thickness between the first surface and the second surface;the inner wall having a third surface thereby defining a thickness between the third surface and the first surface, wherein the thickness between the third surface and the first surface is less than the thickness between the second surface and the first surface;the inner wall having a fourth surface joining the second surface and the third surface, the thickness between the fourth surface and the first surface gradually decreasing from the second surface to the third surface to define a smooth transition therebetween;the second surface intersecting the fourth surface thereby defining a first inflection point and the third surface intersecting the fourth surface thereby defining a second inflection point;the first end including an outer latching profile having a first back angle; and the second end including a female interlocking flange.
