Description: |
| Abstract:
In a gear generating machine of the kind in which the blank is mounted on a rotary table driven by a master worm a and worm-wheel c means are provided for imparting uniform rotary and axial movements to the master worm, the axial movement being compensated by synchronous variations of the rotary movement so that the blank rotation remains uniform. The worm shaft b is driven from a shaft r through bevel gearing p, shaft o, worm gearing m, and differential gearing d. The axial movement is imparted to the shaft b by means of a non-rotary screwed sleeve s mounted between collars on the shaft and traversed by means of a threaded nut-member u integral with a worm-wheel v which is driven from the shaft o through bevel gearing z, shaft 1, change gears 2 - - 5, shaft x, and worm w. In order to compensate for this axial movement, the casing of the differential gearing is rotated by worm gearing i driven through spur gearing 6, 7 from the shaft x. The master worm may be axially advanced or withdrawn continuously or it may be alternately advanced and withdrawn.
