Filed: 1949-12-19
Abstract: 663,508. Gear-cutting. FELLOWS GEAR SHAPER CO. Dec. 19, 1949 [Feb. 9, 1949], No. 32474/49. Class 83 (iii). A gear-shaping machine comprises a back-off sleeve 15 having one internal bearing 18 eccentric to, and another 17 concentric with, its axis of rotation, and a tool-spindle 10 mounted for rotation and reciprocation in the eccentric bearing 18, the reciprocating means for the spindle comprising an oscillating gear sector 31 and a rack section 33 formed on a sleeve 32 mounted in the concentric bearing 17 in the sleeve 15. The spindle is rotated by a wormwheel 21 and is controlled by the usual straight or helical guides 22, 23. The centre a<SP>2</SP> of the sleeve 32 is displaced from the centre a<SP>1</SP> of the spindle in the direction of the line of cutter-and-work centres A-A. Thus, oscillation of the sleeve 15 about its centre a causes the spindle to be backed away from the work, its centre travelling along an arc a<SP>1</SP>-a<SP>2</SP>. The oscillation is imparted by a cam 39 which rocks a sector lever 41 against the force of a spring 50 coacting with a rack-plunger 46 contained between plugs 48, 49. When cutting internal gears, the plugs 48, 49, plunger 46 and sector 41 are reversed in position. To compensate for the additional rotation imposed on the cutter spindle by the rolling of its driving worm-wheel 21 on the driving worm 57, Fig. 5, a cam 75 rocks an arm carrying a planet 63 engaging a driven wheel 65 on the worm-shaft. This corrective movement also prevents rubbing if the cutter and work-piece are in overlapping relationship. In a modification, the sleeve 32 and the sector 31 are provided with two rows of interengaging teeth.
