Abstract

A track wheel has an axially extended hollow hub with internally directed gear teeth capable of receiving an outer toothed driving shaft. The hub is supported by roller bearings in a bearing box from which the wheel may not be inadvertently removed once the box halves have been welded together. The sides of the bearing box have bores in appropriate locations which serve to allow the box to be fastened in a variety of configurations to the element to be transported by the track wheel. The side surfaces of the two halves of the bearing box are provided with recesses for flush and precise arrangement of the roller bearings such that the box can be flushly mounted to other elements. The roller bearings are secured within the recesses by means of snap rings which fit into annular slots located on the outer cylindrical surfaces of the hub.
