SEAL ASSEMBLY FOR TRACK PIN JOINT ASSEMBLY OF UNDERCARRIAGE

摘要

A seal assembly can be incorporated into a track pin cartridge assembly of an undercarriage of a track-type machine. The seal assembly can include a track pin defining a longitudinal axis and first and second members both coaxial with the track 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. A radial segment of a first member engagement surface of the load ring is radially offset, measured along a radial axis perpendicular to the longitudinal axis, from a radial segment of a seal ring engagement surface of the load ring.
