Abstract
Endless track laying work machines are provided with a pair of track laying assemblies positioned on opposite sides of the work machine. Each track laying assembly includes an endless rubber belt entrained around a drive wheel, an idler wheel, and a plurality of mid-rollers. The present mid-roller includes a rotatable member that is positioned between individual roller segments and the guide blocks that are positioned on the inner surface of the endless rubber belt. With the rotatable member in this position, the differential angular velocity between points of contact between the rubber belt and the mid-rollers is compensated for by rotating the rotatable member independent of the individual roller segments. Thus, increasing the life of the individual drive components.
