Abstract
An improved generally annular split sealing ring includes generally curved radially inner and outer surfaces and opposed first and second axial surfaces extending between the inner and outer surfaces. The sealing ring has an axially extending, radially centered axis and a cut extend therethrough from the inner radial surface to the outer radial surface to create a gap to facilitate installation and removal of the sealing ring. The cut extends through the sealing ring along a single continuous cut plane. The orientation of the cut plane is determined by establishing a first reference plane extending radially through the sealing ring and generally parallel to and through the axis. A second reference plane extends generally perpendicular to the first reference plane and midway between the first and second axial surfaces to establish a first generally radially extending reference line. A third reference plane extends generally perpendicular to the first and second reference planes and midway between the inner and outer radial surfaces to establish a second generally axially extending reference line and a third reference line. The cut plane is oriented at a first predetermined angle with respect to the second reference plane and the first reference line and at a second predetermined angle with respect to the third reference plane and the third reference line.
