Abstract

441,535. Gear cutting. LECHESNE, G., 77, Rue Kleber, Montreuil sous Bois, Seine, France. July 29, 1935, No. 21475. [Class 83 (iii)] In a machine for hobbing worm wheels, a wheel 7 to be cut is mounted on a table 5 rotated from a driving shaft 28 by worm gearing 36 and 47, the shaft 28 also driving the cutter spindle 15 through worm gearing 34. The shaft 37 which carries the worm wheel 36 passes through a sleeve 36a carrying the worm 47 and drives the spider 37a, Fig. 3, of a differential gear, one of whose sun-wheels 37b is secured to the sleeve 36a. The other sun-wheel 37c is driven, to compensate for the axial generating motion of the cutter, by worm gearing 41 and a shaft 42 connected to a gear box (not shown), on the machine bed. This gear box also feeds the cutter slide 11 along its horizontal guides 10, for producing the axial generating motion, by means of worm gearing 50a and a screw 51. The reduction ratio of the worm gearing 36 is the same as that of the gearing produced, but the ratio of the gearing 47 is double that of the gearing produced to compensate for the increase in speed effected by the differential gear. The shaft 28 is driven by a belt from a motor 27 and carries a flywheel 29. The horizontal slide 2 carrying the work table 5 is adjusted on the bed 1 at right angles to the cutter spindle axis by means of a screw 17 hand operated at 18.
