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).

A ground-engaging track system includes a track roller having a roller shell with an outer tread surface, and a roller shaft supporting the roller shell for rotation and cantilevering the track roller to a track roller frame. The track roller is positionable in the track system to contact only one of a first track rail or a second rail in a ground-engaging track.

A rotating assembly for a machine is disclosed herein. The rotating assembly includes an annular support structure and a shaft assembly. The annular support structure includes a bore therethrough and protrusion extending helically around a portion of the bore. The shaft assembly includes a shaft and a collar coupled to the shaft. The collar includes a plurality of grooves located at the outer surface of the collar. The collar is positioned within the bore of the annular support structure such that the plurality of grooves are adjacent to the protrusion. As the annular support structure rotates, the protrusion rotates and is configured to move debris and mud out of the rotating assembly.

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 sleeve and the first track shoe and/or the pin.

An undercarriage assembly for a rope shovel includes a crawler frame having a roller component that is disposed at least partially below a crawler body between a first leg and a second leg. The roller component has a lateral roller component bore therethrough. A first crawler frame bushing having a first flanged end is disposed in and through a first lateral crawler frame bore. A roller component bushing-having a first flanged end is disposed in and through the lateral roller component bore, and the first flanged end of the first crawler frame bushing abuts the first flanged end of the roller component bushing.

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.

A track link assembly comprises a plurality of link subassemblies. Each link subassembly may include a pair of links coupled together. Each link may include a first aperture and a second aperture, and the second aperture of each link may be larger than the first aperture. The track link assembly may include a pin element extending through the first aperture of a first link and the second aperture of a second link in each link subassembly. The track link assembly may include a bushing element with a central opening. The bushing element may surround a portion of the pin element and extend through the second aperture of the second link of each link subassembly. The bushing element may include at least one hole configured to couple a track shoe to the bushing element.

The invention relates to a protective covering (4) for sealing a flat spiral spring housing (2), to a flat spiral spring housing arrangement having a protective covering (4), and to a vehicle having a flat spiral spring housing arrangement of this type. The protective covering (4) has a first housing part (2A) and a second housing part (2B) which forms a housing cover, the first housing part (2A) forming, with the second housing part (2B), a receiving space for a flat spiral spring (3), and the two housing parts (2A, 2B) being rotatable with respect to one another. To this end, the flat spiral spring housing (2) has a gap between the first housing part (2A) and the second housing part (2B). The protective covering (4) has an annular disc (9) which extends in the radial direction, and a wall section (10) which adjoins an outer edge of the annular disc (9) and extends in the axial direction, it being possible for the protective covering (4) to be connected to the flat spiral spring housing (2) in such a way that, in a functional state in which it is connected to the flat spiral spring housing (2) to form a flat spiral spring housing arrangement, the protective covering (4) covers the gap between the first housing part (2A) and the second housing part (2B) of the flat spiral spring housing (2) from the outside.
