Patent number: 8721213Abstract: A seal assembly can be incorporated into a track pin joint assembly including a pin defining a longitudinal axis, a first member and a second member both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining a seal cavity disposed in proximal relationship to the second member. A seal assembly including a seal ring and a load ring is disposed in the seal cavity and sealingly engages the first and second members. An axial segment of a seal ring engagement surface of the load ring extends over at least half the length, measured along the longitudinal axis, between a radial segment of the seal ring engagement surface and a radial segment of a first member engagement surface of the load ring. At least one of a load ring engagement surface of the first member and an axial segment of the first member engagement surface of the load ring includes a convex rounded portion.Type: GrantFiled: March 30, 2011Date of Patent: May 13, 2014Assignee: Caterpillar Inc.Inventors: Eric J.
