More Information
Summary:A split seal ring having end faces that self-align in both the axial and radial directions is prepared by forming an opposing first pair of angled grooves extending from an inner edge partway across the seal ring inner diameter, and a second pair of angled grooves extending from the inner edge partway across the seal ring rear surface. In embodiments, corresponding grooves meet to form V- shapes. Additional grooves can extend from the outer edge partway across the inner diameter. Corresponding grooves extending from the outer and inner edges on the inner diameter can terminate at locations that are offset radially and/or angularly. By applying an outward force, the seal ring is split at the groove locations into split ring sections having mating end faces. The resulting end face geometry is sufficiently complex to cause both radial and axial realignment as the seal ring halves are mated together.
