Abstract

1,189,175. Rolling gear-wheels. VICKERS Ltd. 19 Feb., 1969 [1 Dec., 1967], No. 54793/67. Heading B3M. A gear-wheel is cold-formed from a cylindrical blank by two series of tool projections, the projections causing metal from the two edges of the blank periphery to be displaced axially inwardly during the cold-forming. The projections can be formed in a platen 3, 4, with two such platens being reciprocated on opposite sides of the blank to roll teeth into its periphery. Projections 2 are provided at the edges of each platen and are formed in groups which gradually increase in size from the leading end 3 of the platen. The projections are tapered inwardly, and progressively extend towards each other until continuous teeth 2<SP>1</SP>, 2<SP>11</SP>, and finally 2<SP>111</SP>, are formed.
