Abstract:
A chain tensioner for a track of a track vehicle that has a track tensioning assembly including a compression spring mounted on to a shaft. The spring is captured between a pair of retainers, the outer end one of which is mounted to permit limited sliding movement of the spring during use. The limited sliding movement is provided by one of the retainers comprising a sliding block that is supported in position with a pair of cross pins that pass through cross recesses on opposite sides of the shaft to hold the block while permitting axial movement of the block between desired limits in longitudinal direction. The cross pins also to retain the block against rotation about the central axis of the shaft. The block will slide easily, and when used with hardened parts gets long wear life as well as maintaining a tension in the track as it moves.
