ABSTRACT:
A split beveled retaining ring and method for constructing the same is characterized by a beveled groove seating flange being formed by bending the radially inner or outer edge portion of a split ring body at an angle to the plane of the ring body. A grinding operation may be employed to remove protruding material from the bent annular flange on the side of the ring opposite the groove seating surface thereon to provide a flat bearing shoulder normal to the ring axis while permitting enough of the beveled flange to be received in the groove for safe part retention. Alternatively, the part abutment surface of the ring body may be maintained in substantially the same plane as the terminal portion of the bent beveled flange either by indenting the ring body to form a new part abutment surface or by bending the groove seating flange twice in opposite directions.
