Abstract
965,499. Gear-cutting. NATIONAL BROACH & MACHINE CO. July 11, 1963 [June 25, 1962], No. 24268/62. Heading B3K. [Also in Division F2] A gearhobbing machine comprises a hobhead swivelling on a headstock movable for feed and traverse, an electric motor 5 mounted on the headstock driving a main shaft 4 through change-speed gears 8 and connected to a power input shaft 15 of the hob-head through a first reduction gear consisting of a small face gear 12 on the main shaft meshing with a radially disposed long spur gear 13 mounted on the headstock with its axis substantially parallel to the work axis, the spur gear 13 also meshing with a larger face gear 14 fixed to the power input shaft 15 which drives the hob through a pair of bevel gears 16, 17 and a pair of spur gears 19, 20 forming a second reduction gear. The headstock is adjustable in the direction D and carries the hob head traversable in the direction B and angularly adjustable in the direction C about the axis of the gear 16, the hob being axially adjustable in the direction A. The direction of hob feed can be parallel to the work axis or at the helix angle thereto.
