Abstract

712,243. Toothed gearing. ARON, E., and PULMAN, W. E. R. May 2, 1952 [May 2, 1951], No. 10332/51. Class 80 (1) An arrangement of gearing for transmitting a drive between two shafts with axes disposed at right angles and spaced apart. in order to allow of' relative movement in the direction of one of the axes, comprises a gear 19 with straight teeth on one shaft 20 which meshes with a helical idler gear 16 on an oblique axis 17 which meshes also with a gear 14 on the other shaft 11. Movement of the shaft 11 together with the idler gear 16 along the direction of the axis of shaft 20 is allowed by the sliding of the helical teeth of gear 16 along the straight teeth of gear 19 which is made sufficiently long for the purpose. The invention is particularly applicable to indexing mechanism for a machine tool turret such as described in Specifications 712,242, 712,244 and 712,245, [all in Group XXII], the shaft 11 forming the turret spindle mounted together with the idler gear 16 on the turret slide 13 and the shaft 20 being an intermediate shaft for driving the turret through the gears 19, 16, 14.
