Method for manufacturing driving wheel, involves dimensioning mold corresponding to hollow cylindrical wheel shaft based on predetermined dimensions of wheel shaft of blank

摘要

The method involves providing a mold structure comprising molds corresponding to shapes of rotationally symmetric wheel head and hollow cylindrical wheel shaft. The mold corresponding to hollow cylindrical wheel shaft is dimensioned based on the predetermined dimensions such as length, thickness and diameter of wheel shaft (2-2) of blank (11). The blank is forced into the dimensioned mold structure of wheel head and wheel shaft. An independent claim is included for blank.
