Abstract: A track roller for a mobile machine is disclosed. The track roller may have a shaft defining a central axis, and a roller body connected to the shaft and configured to rotate around the central axis relative to the shaft. The track roller may also have a sealing member positioned between the shaft and the roller body, and a collar member secured to the shaft and at least partially covering the sealing member. A passageway having an opening may be defined between the collar member and the roller body. The track roller may further have a guard member secured to the shaft, the guard member having a main body and an upper rim extending from the main body towards the roller body. The guard member may also have a plurality of projections extending from the main body towards the roller body, and a plurality of openings formed between the upper rim and the projections.

Abstract: A seal packing guard is provided in a roller assembly of a machine, such as a track carrier roller of a track-type undercarriage. The roller assembly includes a roller mounted on a shaft and having a seal retaining lubricant between the roller and the shaft. A collar and an inner surface of the roller form a seal cavity placing the seal in fluid communication with an ambient atmosphere surrounding the roller. The seal packing guard is attached to an outward surface of the roller and extends over an opening into the seal cavity to reduce the amount of abrasive material entering the seal cavity and potentially compromising the integrity of the seal.

Abstract translation: 在机器的辊组件中，例如轨道式起落架的轨道承载辊上设置密封衬垫防护件。 辊组件包括安装在轴上的辊，并且在辊和轴之间具有保持润滑剂的密封件。 辊的轴环和内表面形成密封腔，其将密封件与围绕辊的环境大气流体连通。 密封衬垫防护件附接到辊的外表面，并且在开口处延伸到密封腔中以减少进入密封腔的研磨材料的量并潜在地损害密封件的完整性。

Abstract: A track link for a ground-engaging track system includes a link body having a pin bore formed in a first link strap and a bushing bore formed in a second link strap. The link body includes, upon an outboard link side, a bore peripheral surface extending circumferentially around a bore center axis, and a guide protrusion including an outer bump surface located outboard of the bore peripheral surface. The pin bore receives a track pin attached by swaging and defines a diametric plane through the bore center axis oriented parallel to an upper rail surface. At least a majority of the outer bump surface is between the diametric plane and the upper rail surface, and an entirety of the outer bump surface may be between the bore center axis and the upper rail surface. The guide protrusion protects material of the track link and/or track pin from wear that can prevent re-swaging.
