Abstract A toothed tool for the roll-working of toothed workpieces. There is provided a toothed tool having spaced serrations along the length of a tooth, said serrations extending from the dedendum to the addendum of the tool teeth whereby said serrations define a plurality of spaced ribs on the tool teeth. Said serrations are arranged in such a manner that the ribs are off-set on one tooth with respect to the corresponding ribs on an adjacent tooth. The relative width and spacing of the serrations and ribs are such that the sum of widths of the ribs on one tooth flank is equal to the sum of the width of ribs on all, or at least most, of the other tool flanks facing in the same direction.
In a toothed tool for working of gears by rolling which is provided with serrations extending from addendum to dedendum, ribs forming the tool tooth flanks being adjacent and defined by said serrations and being arranged offset with respect to one another on the successive teeth, the improvement comprising the sum of the widths of the ribs in axial direction on one circumferentially facing side of a tool tooth equals the sum of the widths of the ribs on the same circumferentially facing side of at least the majority of the other teeth of the tool.

A toothed tool according to claim 1, wherein the sum of the widths of the ribs in axial direction of the teeth on said one circumferentially facing side equals the sum of the widths of the ribs on both circumferentially facing sides of at least the majority of the other teeth of the tool.
Claim 4
Dependent Claim
17 words
A toothed tool according to claim 1, wherein the width of each of said ribs is equal.
Claim 5
Dependent Claim
66 words
A toothed tool according to claim 1, wherein the combined width of one of said ribs and one adjacent serrations thereby defining a mutually adjacent pairing is equal to the fraction of 1/N in relationship to the width of said tool where N equals the total number of mutually adjacent pairings axially across the tooth of said toothed tool and thereby the width of said tool.
