Abstract: 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.

Abstract: 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.

Abstract: A seal includes an annular body defining a radial direction, an axial direction, and a circumferential direction; and further defines a cross-sectional area including a perimeter. The perimeter may comprise a first axial extremity, a second axial extremity, an outer radial extremity, and an inner radial extremity. The perimeter may include a first axial extremity defining surface and a second axial extremity defining surface, a first concave arcuate surface interposed between the inner radial extremity and the second axial extremity, and a second concave arcuate surface interposed between the outer radial extremity and the second axial extremity.

Abstract: A face seal includes first and second members which are mounted together, a seal member, and a backup ring. The first member extends along a longitudinal axis and defines an interior cavity. The first and second members each includes a respective sealing surface that extends radially relative to the longitudinal axis. At least one of the sealing surfaces defines an annular groove. The seal member is disposed within the annular groove and is in sealing contact with the sealing surfaces. The backup ring is disposed within the annular groove such that the seal member is radially inward of the backup ring. One sealing surface is movable relative to the other sealing surface in response to increased interior cavity pressure, thereby defining a gap therebetween. The backup ring is interposed between the seal member and the gap such that the backup ring occludes an opening to the gap.
Abstract translation: 面密封件包括安装在一起的第一和第二构件，密封构件和备用环。 第一构件沿着纵向轴线延伸并限定内腔。 第一和第二构件各自包括相对于纵向轴线径向延伸的相应的密封表面。 密封表面中的至少一个限定环形凹槽。 密封构件设置在环形槽内并与密封表面密封接触。 支撑环设置在环形槽内，使得密封构件在备用环的径向内侧。 响应于增加的内腔压力，一个密封表面可相对于另一个密封表面移动，由此在它们之间形成间隙。 支撑环插入在密封构件和间隙之间，使得支撑环封闭到间隙的开口。

Abstract: A sealing comprises a seal portion and a plate portion fixed to the seal portion. The seal portion can have an undulating configuration of at least one peak and at least one valley, and the plate portion can circumferentially surround the seal portion. The seal portion can be made of a first material and the plate portion can be made of a second material more rigid than the first material. The seal portion can have a radially inward facing contact surface that defines a central opening of the sealing.
