Abstract

616,342. Toothed gearing; screw-and-nut gearing. CENTRE D'ETUDES TECHNIQUES ET D'INVENTIONS. June 6, 1945, No. 14265. Convention date, Sept. 25, 1941. [Classes 80 (i) and 80 (iii)] In a mechanism for eliminating backlash, especially in gear-cutting machinery, the member taking up the slack is similar to and driven by the driving member, and is connected thereto through a vernier adjustment so that it is always in contact with the driven member. A worm-wheel 11 is driven by a worm 10 which has a bevel 13 secured to its shaft. A second worm 15 also meshing with the wheel 11 has a freely rotatable sleeve 17 on the end of its shaft. A bevel gear 14 integral with the sleeve meshes with the bevel 13. The end of sleeve 17 is formed as a toothed ring, a second toothed ring 18 being keyed to the end of the shaft of the worm 15, between these two'rings is fitted a double toothed ring 16. The numbers of teeth in rings 17, 18 being slightly different, a vernier is formed and a worm 15 can be driven in the same direction as worm 10, but its teeth will bear constantly against the opposite flanks of the teeth of the worm-wheel 11 and so eliminate backlash. In a modification for use with screw-and-nut mechanism, a second screw, driven by gearing through a vernier, is provided on the opposite side of the main member moved, backlash being eliminated by similar opposite pressures between the screw-threads.
