US Classification:

305201, 305118, 305198

Abstract:

A bushing for use in a tracked undercarriage of a track-type machine includes a first end and a second end disposed opposite the first end. An outer surface extends between the first end and the second end and is shaped to engage a sprocket of the tracked undercarriage. The bushing also includes an annular inner surface disposed between the first end and the second end defining an internal cavity shaped to receive a track pin. An innermost portion of the inner surface forms a crown having a radius less than or equal to (PL)/[(24EπDR)(1−cos [(PL)/(16EπDR))] where L is the length of the bushing, P is the weight of the track-type machine, E is the Modulus of Elasticity of the bushing, and Ris a radius of the innermost portion of the annular internal cavity.

International Classification:

F16P 1/00

US Classification:

305203000

Abstract:

A cartridge bearing assembly for a track chain of a track type work machine is provided. The cartridge bearing assembly includes axial/radial load bearing insert members positioned about a pin, and a rotatable bushing positioned therebetween. Crowned sleeve bearings are disposed between the insert members and the pin, as well as between the pin and the rotatable bushing. Collars are disposed at opposite ends of the pin and fixedly coupled thereto, trapping the other components of the cartridge assembly therebetween. A method of operating a track type work machine is further provided, including reducing wear between coupled track links by reacting axial loads via insert members positioned about a track pin.

US Classification:

403119, 277503

Abstract:

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.

Abstract:

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, at least in part, an axially-extending 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 member and the second member. At least one of a load ring engagement surface of the first member and an axial segment of a first member engagement surface of the load ring includes a convex rounded portion extending over at least half the axial length thereof.
