摘要： The disclosed system includes a personal computer (10) having correction coefficients (±) for the correction of errors in the tooth profile and correction coefficients (²) for the correction of meshing positions, the correction coefficients being provided for each number of times the shaving cutter has been sharpened and for each shaving-cutter feature. The target tooth-profile data (Do), the tooth-profile error data (”D) which is the difference between the target tooth-profile data (Do) and the measured tooth-profile data (Dm), and the correction coefficients (± and ²) acquired in correspondence with the number of times sharpened and the cutter features are applied to the equation Dcc=Do+±”D+², to fnd the aimed tooth-profile data (Dcc). Then, the shaving-cutter tooth-profile data (ds) is found from the aimed tooth-profile data (Dcc). Thus, the shaving cutter can be sharpened appropriately, even when the outer diameter and the tooth thickness of the shaving cutter are reduced as a result of sharpening the shaving cutter.

摘要： The disclosed system includes a personal computer (10) having correction coefficients (α) for the correction of errors in the tooth profile and correction coefficients (β) for the correction of meshing positions, the correction coefficients being provided for each number of times the shaving cutter has been sharpened and for each shaving-cutter feature. The target tooth-profile data (Do), the tooth-profile error data (ΔD) which is the difference between the target tooth-profile data (Do) and the measured tooth-profile data (Dm), and the correction coefficients (α and β) acquired in correspondence with the number of times sharpened and the cutter features are applied to the equation Dcc=Do+αΔD+β, to fnd the aimed tooth-profile data (Dcc). Then, the shaving-cutter tooth-profile data (ds) is found from the aimed tooth-profile data (Dcc). Thus, the shaving cutter can be sharpened appropriately, even when the outer diameter and the tooth thickness of the shaving cutter are reduced as a result of sharpening the shaving cutter.

摘要： A tool for producing crown wheels by means of a generating process comprises a disc which is rotatable about its axis, with machining elements which are provided on the periphery thereof and the cutting edges of which lie in the outer surface of a profile determining the shape of the teeth of a crown wheel to be produced with the tool, said profile extending essentially helically over the periphery of the disc. In each cross-section of the helical profile the outer contour (25) of the cross-section is at least composed of a part of the outer contour of the tooth profile of an imaginary gear wheel (23) with involute teeth and preferably straight lines connecting thereto, in such a way that in the case of each of the teeth (22) with a tooth tip and two tooth flanks bounded by the outer contour (25) of the cross-section the distance between each of the two tooth flanks and a line at right angles to the axis of rotation of the tool and passing through the tooth tip remains the same or increases from the tooth tip to the axis of rotation of the tool.

摘要： A hob cutter (4) for machining face or crown gears comprises a disc-like cutter body having an axis of rotation (6) and a number of hob teeth groups (1, 2, 3, ...) which are uniformly distributed over the circumference and which are each bounded at the front by a cutting face (S) and at the circumferential side by a clearance face (V). The cutting face and the clearance face of each hob teeth group intersect one another in a cutting edge (9) which determines the shape of the face gear to be machined. The clearance face of each hob teeth group is made up of a number of generatrices (L, m) which are each situated in a machining plane which is determined by a line which intersects or crosses the axis of rotation (6) perpendicularly and intersects the generatrix at the position of the cutting edge. The extensions of the generatrices (L, m) determining the clearance face run at a minium spacing over the outside of the downstream hob teeth group.

摘要： A cutter for producing face gears, comprising a disc-shaped cutter body with cutting teeth (23) fitted on the periphery. The cutting edge (24) of each cutting tooth lies in a surface of revolution which is produced by turning an imaginary gear wheel of infinitely low thickness about the axis (20) of the cutter and simultaneously about its own axis. Each cutting tooth (23) of the cutter is of such a shape that the cutting tooth is re-grindable, without the shape of the cutting edge of the cutting tooth changing as a result. This is achieved through the fact that the profile of each cutting tooth shifts in planes (22, 22a, 22b...) from the cutting edge (24) of the cutting tooth to the rear side thereof in the direction of the axis (20) of the cutter.
