摘要： A sprocket segment includes a body with an attachment web including a first circumferential end and a second circumferential end. A sprocket region extends radially outwardly from the attachment web, including a plurality of lugs. The first circumferential end includes a dovetail recess including a first side flat surface extending circumferentially and radially from the first circumferential end, a second side flat surface extending circumferentially and radially from the first circumferential end, and an arcuate bottom surface extending radially between the first side flat surface and the second side flat surface.

摘要： 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.
