Abstract

1,270,588. Gear cutting. SKODANARODNI PODNIK. 26 Dec., 1969 [29 Dec., 1968], No. 62855/69. Heading B3K. Apparatus for machining a globoid worm 1 comprises a disc-shaped rotary tool 4 mounted on a table 20 which is arranged to rotate about the axis of a shaft 17 in meshing relation with the worm to be machined, a rack 19 being mounted on the table and arranged to mesh with a stationary pinion 18 whereby on rotation of the table the rack is displaced and this displacement is used to actuate a cam 16, the profile of which, through suitable transmission elements including Selsyn motors 10, 7 controls means for modifying the angular disposition of the tool shaft relative to the worm 1 in dependence upon variations in the lead angle of the worm helix.
