Abstract

18,479. Maag, M. Feb. 11, [Convention date]. Dividing-engines.-For eliminating back lash in machine gears, in addition to the main gears 3, 5, an auxiliary gear 7, 9 is employed, such auxiliary gear being designed to operate the driven member at a speed slightly greater than the main drive, and excess of speed being taken up by an adjustable yielding power transmitter 10, 11. Fig. 1 shows the device applied to driving the slide block 2. In a modification, the application is shown to worm gearing in combination with toothed or bevel gearing. The arrangement is particularly applicable to the dividing-wheels of gear-cutting machines and to fine dividing-machines generally, the auxiliary driving-means relieving the main spindle of the greater part of the required effort.
