Abstract

1,043,717. Gear-cutting. LIGHTNING FASTENERS Ltd. Oct. 30, 1964 [Aug. 16, 1963], No. 32504/63. Headings B3K and B3T. [Also in Division F2] A machine for cutting worms or threads of non-constant helix angle or tools for cutting them comprises means for rotating a worm blank 3 or hob at a constant angular velocity and a differential mechanism having an output shaft 9<SP>1</SP> for rotating the generating cutter 11 or a worm-wheel blank, and a cam 21 rotatable at an angular velocity fixed relatively to the angular velocity of an input shaft 9 of the differential mechanism, the cam being operable to rotate the cage 14 of the differential so that the output shaft of the differential has a variable angular velocity. The hour-glass worm 3 is carried on a slide 5. The cutting surface of the cutter 11 is in line with the work axis. The cam 21 oscillates the cage 14 through a lever 17. The cam may be designed to produce a linearindexing cam gear having dwell periods. The cam may further be designed to rotate only one for several revolutions of the work. A wormwheel having teeth as shown in Fig. 1 may be cut.
