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 (13, 16) consists of only four gears in a machine for cutting internal gears and consists of only four gears (65, 67, 80, 84) and a direction-changing idler (81, 82) in a machine for cutting external gears. Relative infeeding of the cutter (12) and the work blank (11) 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.

Abstract: The hobbing machine (20) 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, its drive train consists of only four gears (66, 67, 70, 71) and its hob head (50) is mounted to pivot around the axis (65) of the drive shaft (63) for the work spindle (24). The arrangement of the four gears (66, 67, 70, 71) together with the pivotal mounting of the hob head (50) enables the hob spindle (23) to be inclined at a predetermined setting angle relative to the work spindle (24) and enables the center distance between the spindles to be selectively changed.
