ABSTRACT:
A method of making a robust sprocket for a tracked combat vehicle includes orming flat steel plates from stock metallurgically dissimilar to and harder than that of the track shoes, the thickness of the plates being at least 0.72 times the axial width of track shoe pockets engaging teeth of the sprocket. The sprocket's teeth are formed by water jet machining, so that the metallurgy of the sprocket and the sprocket's flatness are unaffected by the tooth formation process, and so that the bearing surfaces of the teeth are smooth. After tooth formation, selected zones of the teeth are then hardened.
