Abstract

1,248,931. Toothed gearing. N. WADDLETON (Koyo Seiko Co. Ltd.). 26 Sept., 1968, No. 14497/68. Heading F2Q. In a variable ratio steering gear comprising a nut 4 mounted on a helical groove 2, formed in a steering shaft 1, by circulating balls 6, and a toothed sector 9 on an output shaft 8 meshing a rack 7 formed on the nut 4, teeth on each side of a central tooth of the sector 9 have a pitch diameter which progressively increases in accordance with angular displacement of the sector from its neutral position to provide uniform variation of the gear ratio, and the change in pitch diameter is accompanied by a similar symmetric increase in the number of teeth, i.e. the number of teeth the sector would have if it were a complete circular gear. The pressure angles on the right- and left-flanks of the rack teeth meshing with the sector may be unequal in order to increase the thickness of the dedendum of the neutral tooth in the middle portion of the sector.
