Abstract
A single-tooth cutter for sloping the axial face of gears, in which the gear which is to be worked performs a continuous or step-by-step rotary movement whereby successive rotations of the single-tooth cutter will cause a working on successive teeth at least one sloped surface, and in which the workpiece and the single-tooth cutter after each workpiece rotation approach one another, until the desired sloped shape is reached, the chip removal occurring through the provision of at least two edges which in peripheral direction are arranged one directly behind the other. A cutter which can also be used for this has two edges which act one directly after the other, which edges can have a different distance from the axis of rotation of the cutter.
Claims8
In a single-tooth cutter for sloping the axially facing end faces of teeth of gears by a hob-milling method, said cutter being rotatably supported for movement about an axis of rotation, and having thereon a cutting tooth with a cutting edge means spaced radially outwardly from said axis of rotation, said cutting edge means extending along a side of said cutting tooth which faces said axis of rotation of said cutter for effecting a working, during successive rotations of said cutter, at least one sloped surface on said axially facing end faces of said teeth on said gears, the improvement comprises wherein said cutting edge means includes plural cutting edges, and wherein at least two individual cutting edges follow one another in a peripheral direction of said cutter and lie on the same flight circle.
In a single-tooth cutter for sloping the axially facing end faces of teeth of gears by a hob-milling method, said cutter being rotatably supported for movement about an axis of rotation and having thereon a cutting tooth with a cutting edge means spaced radially outwardly from said axis of rotation, said cutting edge means extending along a side of said cutting tooth which faces said axis of rotation of said cutter for effecting a working, during successive rotations of said cutter, at least one sloped surface on said axially facing end faces of said teeth on said gears, the improvement comprising wherein said cutting edge means includes plural cutting edges, and wherein at least two individual cutting edges of said cutting edge means follow one another in a peripheral direction of said cutter, said individual cutting edges being arranged circumferentially offset in such a manner that a leading one of said cutting edges which precedes the one of said cutting edges in the direction of movement of said cutter decisive for determining the desired shape of said slope lie a greater distance from said axis of rotation and on a greater flight circle than said leading edge.
