Abstract:

Relates to a method of arranging worm gearing. The driven shaft B, Figs. 1 and 2, has a number of worm-wheels A', A<2>, &c. which are driven by a corresponding number of worm shafts C<1>, C<2>, &c. The ends of the worm shafts are enclosed in thrust bearings D<1>, D<2>, the end thrusts being balanced by an arrangement of levers H', H', G. The lever G is pivoted at F and secured by a bolt f to the bed - plate. In the collar thrust bearing shown in Fig. 1, the half-bushes D<4> are nested in the sliding sleeve D<2>, which in turn is fitted in the bed-plate or headstock E of the driving- gear. Arrangements of levers are also deecribed for three or four worm shafts so that each worm similarly acts as the support or abutment of the other. In an alternative hydraulic compensating arrangement, the ends of the sleeves D<1> &c. project into a pressure box G, Fig. 5, kept full of oil or other liquid by means of a pump &c. through the pipe G'. The arrangements may be used with racks in lieu of worm-wheels, and they may be applied to planing-machines.
