Abstract
The gear shaping machine is of simplified construction and is dedicated essentially to forming only a single type of gear or a narrow range of gears. To enable the machine to be of simplified construction, the drive train between the cutter and work spindles consists of only four gears in a machine for cutting internal gears and consists of only four gears and a direction-changing idler in a machine for cutting external gears. Relative infeeding of the cutter and the work blank is effected by pivoting one of the spindles relative to the other spindle with one of the drive gears walking around another one of the drive gears during such pivoting. The differential rotation of the spindles produced by the pivoting action is negated in order to keep the spindles in proper rotational relationship.
