842,516. Toothed gearing. GLEASON WORKS. March 31, 1958 [March 29, 1957], No. 10294/58. Class 80 (1). Compensation for backlash in a spiral bevel or hypoid gear drive 13, 12 from a driving shaft 15 to a driven shaft 11 is effected by a secondary drive pinion 14 on to the gear 12 which is driven from the shaft 15 through a pair of helical gears 24, 37 and a spring coupling 42, 43. The coupling is adapted to be loaded in one direction or the other according to the direction of drive by adjusting the axial position of gear 37 relative to gear 24. The spring coupling 42, 43 has springs acting in both directions from each member of the coupling but if rotation in only one direction is necessary the coupling need only have single acting springs. |
