摘要： In some implementations, a bushing may include a cylindrical body having an at least partially annular configuration. The cylindrical body may define a radial axis and may include an inner circumferential surface, an outer circumferential surface, a first end, and a second end. The inner circumferential surface may be configured to rotatably receive an outer surface of a pin of a track link joint. The outer circumferential surface may be configured to be rotatably received within a first counterbore of a first track link of the track link joint. The bushing may include at least one groove extending radially into the outer circumferential surface around the radial axis. The at least one groove may be configured to receive a first seal of the track link joint. The first seal may form a first radial seal between the outer circumferential surface and a first inner surface of the first counterbore.

摘要： The invention relates to a deflector arrangement (100) for a tracked vehicle (V). Said tracked vehicle (V) comprises at least one track assembly (T1, T2) comprising two end wheels (1, 2) in the form of a front wheel (1) and a rear wheel (2), and further a plurality of road wheels (3) there between. At least one of the front wheel (1) and rear wheel (2) is a drive wheel (1) and at least one of the front wheel (1) and rear wheel (2) is a tension wheel (2). The track assembly (T1, T2) further comprises an endless track (4) disposed around said end wheels (1, 2) and plurality of road wheels (3). Said deflector arrangement (100) is configured to reduce ingestion of undesired material from the ground (G) into said track assembly (T1, T2) and remove such undesired material from said track assembly (T1, T2). Said deflector arrangement (100) is associated with an end wheel (1, 2) and is resiliently suspended and biasedly arranged so as to strive towards the inner surface (4a) of the endless track (4).

摘要： A seal assembly for sealing a lubricant space that is formed between a pin, a track shoe pressed-on onto one end of the pin, and a sleeve of a track. The sleeve is pushed onto the pin and is swivelable on the pin. The track further includes at least one second track shoe pressed onto one end of the sleeve. The seal assembly provides a first seal ring for sealing the lubricant space between the sleeve and the first track shoe, and an elastic ring for applying pressure to the first seal ring. The seal assembly further provides a second seal ring for sealing the lubricant space between the sleeve and the first track shoe and/or the pin.

摘要： A link assembly includes a first member, a second member opposing the first member and being rotatable around a rotating shaft, a seal housing formed between the first and second members, and a seal assembly disposed inside the seal housing. The seal assembly has a seal ring and a load ring. The seal ring has a support ring and a lip ring. The seal ring is disposed between the first member and the load ring. The load ring is disposed between the seal ring and the second member. The lip ring abuts the load ring. The lip ring has a first lip part that abuts the first member and protrudes in an axial direction of the rotating shaft, and a second lip part that abuts the second member and protrudes in a radial direction perpendicular to the rotating shaft.

摘要： A seal protection mechanism for a shaft seal of a land-based vehicle is described. The seal protection mechanism comprises a fixed part and a rotary part. The fixed part is fixed relative to the vehicle. The rotary part is rotatable relative to the fixed part about an axis. The rotary part is configured to rotate with a shaft about which the shaft seal is disposed. One of the fixed part and the rotary part comprises an axial opening. The other of the fixed part and the rotary part is at least partly received in the axial opening. The fixed part and the rotary part define a passageway. At least one of the fixed part and the rotary part comprises a debris breaking portion. The debris breaking portion is disposed in the passageway. In use, rotation of the rotary part relative to the fixed part causes the debris breaking portion to break apart any debris passing through said passageway towards the shaft seal. The seal protection mechanism therefore acts to protect the shaft seal by breaking apart debris before said debris can reach the shaft seal. This is beneficial because the shaft seal is a vulnerable component which can be damaged by debris.

摘要： A track roller for an undercarriage system includes a roller shell with a first inner surface forming a larger diameter shaft bore and a second inner surface forming a smaller diameter shaft bore coaxially arranged with the larger diameter shaft bore. A roller shaft having a first shaft end and a second shaft end supports the roller shell for rotation and has an oil reservoir formed therein. A first sleeve bearing and a second sleeve bearing are positioned upon the roller shaft, and an axially extending oil passage is formed by the second inner surface of the roller shell forming the smaller diameter shaft bore and an outer bearing surface of the second sleeve bearing. The oil reservoir in the roller shaft is confined in its extent to the second shaft end of the roller shaft.

摘要： A track chain assembly includes a first track pad including a first pair of lugs defining a gap therebetween, and a second track pad including an intermediate lug disposed in the gap. The first pair of lugs and the intermediate lug each define a concentric bore, defining an axis of rotation for a pinned joint of the track chain assembly, and the concentric bore of one of the first pair of lugs is in communication with the gap with a first blend disposed axially between the gap and the concentric bore.

摘要： A wheel of a track system for traction of a vehicle (e.g., an agricultural vehicle) may be configured to protect against (e.g., prevent) accumulation of unwanted ground matter, such as mud, debris, water, etc., within the wheel, while enhancing visual appearance of the wheel. This may help to avoid or minimize mud buildup that may otherwise need to be drilled out before removing the wheel (e.g., for replacement or maintenance) and/or rust that may otherwise arise.

摘要： A mining machine includes a frame having a guide rail, the guide rail having a central portion. The mining machine also includes a shoe having a recessed area that defines a roller path, the shoe further having a drive lug, wherein the central portion of the guide rail is configured to be disposed within the recessed area. The mining machine also includes a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool.
