Embodiment Construction

[0047] see figure 1 With the shown machine tool, the following is a description of the machine tool axes relevant to the invention. On the right side of machine bed 10 (see figure 1 ), the workpiece table 6 is arranged in a horizontal plane and is conventionally configured for holding the workpiece 2 (in figure 1 not shown), such as external gears. Thus, the gear axis Z is oriented vertically, which has the same orientation as the direction of movement of the axial carriage 3 (to be described below). The direction of rotation of the gear 2 about the gear axis Z will be denoted C.

[0048] According to the design known per se, it is arranged on the left side of the frame 10 (see figure 1 ) The radial carriage 1 is configured to move linearly relative to the workpiece table 6 . A radial direction X is defined by a movement in a radial direction relative to the gear 2 clamped to the workpiece table 6 . In one embodiment of the method according to the invention, the radial p...

Abstract

The invention relates to a method for machining gear teeth whose tooth faces deviate from their specific geometry by a machining allowance, wherein the machining allowance is removed by feeding in at least two feed steps, each The feed steps are followed by a machining stroke with a forming tool rotating around the tool axis, for which operation the tool is set in a position relative to the gear according to the angle of inclination of the plane of rotation orthogonal to the tool axis and the gear axis Afterwards, the profile tool engages the gear teeth and after each feed step material is removed in the final mating area of ​​the tool and after the last feed step and due to the angle determined by the design angle of the profile tool Angle of inclination, the tool mating area extends over the entire tooth flank height so that the next machining pass removes the amount of material required to obtain the specified geometry, wherein, in at least one infeed step before the final infeed step, the forming The tool is set at an inclination angle that deviates from the angle designed for the tool and results in an enlarged tool engagement area in the height direction of the tooth flank compared to setting at the designed angle.

Description

technical field [0001] The invention relates to a method for machining gear teeth whose tooth faces deviate from their prescribed geometric shape by an allowance, wherein the allowance is removed with an infeed of at least two feed steps, each Each feed step is followed by a machining pass with a profile tool rotating around the tool axis, for which operation the profile tool has been set at an angle inclined to the gear axis according to its plane of rotation orthogonal to the tool axis Whereas relative to the position of the gear thereafter engages with the gear teeth and after each feed step the material in the final mating area of ​​the tool is removed and after the last feed step and due to the design of the forming tool With defined profile tool inclination settings, the tool counter area extends over the entire tooth flank height, so that subsequent machining strokes remove the amount of material required to obtain the defined geometry. Furthermore, the invention relat...
