The hobbing 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, its drive train consists of only four gears and its hob head is mounted to pivot around the axis of the drive shaft for the work spindle. The arrangement of the four gears together with the pivotal movement of the hob head enables the hob spindle to be inclined at a predetermined setting angle relative to the work spindle and enables the center distance between the spindles to be selectively changed. |
