Abstract

947,486. Machine tool details. CROSS CO. March 14, 1960 [March 19, 1959], No. 8846/60. Heading B3B. [Also in Divisions F2 and H2] In a machine tool drive providing slow rate of feed or rapid traverse wherein a speed reducing gear 182 comprises coaxial output and primary input shafts 196, 194 and a reactionary or secondary input member 198, for low speed drive reducing through the gear 182 with the member 198 braked at 256, a motor 212 drives the primary input shaft 194 through reducing gears 208, 200; and for high speed drive, substantially at 1/1 ratio through the gear 182 with or without energization of the motor 212, a second motor 234 drives the member 198 through reducing gears 238, 236, the brake 256 being released. As shown, the output shaft 196 drives a vertical axis rotary table through a tongue- and-slot coupling 226, change-wheels and worm gearing. The speed reducing gear 182 comprises an eccentric on the primary input shaft 194 having ball-journalled thereon a planet 296 meshing both an internal ring gear 300 fast with the member 198 and an internal ring gear 202 which is integral with the output shaft 196 and has a number of teeth different from that of the internal ring gear 300. Changewheel gears 208, 200 and electric motors 212, 234 may be reached and the speed reducing gear may be reached or removed without disturbing a main housing 172, and the brake 256 may be withdrawn from a casing 262 integral with a cover 190. In Fig. 1 the output shaft linearly drives a sliding saddle through a tongue-and-slot coupling and a screw and nut remote from reversible motors and the brake. The speed reducing gear comprises a primary input cam, an internal ring gear fixed to the reactionary or secondary input shaft, and an output externally toothed planet comprising a flexible ring having one or two teeth less than the internal ring gear.
