Embodiment Construction

[0015] exist figure 1 In this case, the teeth 7 of the planing wheel 4 are in engagement with the teeth 5 of the wheel blank 3 . Here, the skiving wheel 4 has its deepest axial penetration position. The tool spindle 2 only needs to be reduced slightly in the neck area 11 in order to avoid a collision with the edge of the wheel blank 3 .

[0016] Depend on figure 2 with 3 It can be seen that the skiving teeth 7 of the skiving wheel 4 always engage in the tooth gap 6 between the two teeth 5 of the wheel blank 3 . exist figure 2 In the position shown, the teeth 7 of the skiving wheel 4 in positions c and e are in the engaged position. exist image 3 , the skiving tooth 7 arranged at position e is located in the deepest engagement position in the tooth gap 6 of the wheel blank 3 . In contrast to the prior art, the number of simultaneously engaged teeth 7 , 5 is reduced.

[0017] Although each tooth gap 6 is only machined every second revolution of the wheel blank 3 , a v...

Abstract

The invention relates to a device for generating teeth of workpieces (3) by hob peeling, having a workpiece spindle (1) that can be rotatably driven for accommodating the work wheel (3) to be geared, particularly internally, and having a tool spindle (2) that can be rotatably driven, said tool spindle (2) carrying a peeling wheel (4), which has a regular tooth pitch determined by the tooth spacing of the gearing of the workpiece (3). In order to improve the performance of the generic device and / or generic method, and to provide the peeling wheel suited therefor, it is proposed that the distance between at least some of the teeth of the peeling wheel (4) that are of identical shape corresponds to a multiple of the regular tooth pitch.

Description

technical field [0001] The invention relates to a device for gearing a wheel blank by hobbing, with a rotatably drivable workpiece spindle and a rotatably drivable tool spindle for receiving, in particular, internal gearing Wheel blank, tool spindle supports planing wheel with cutting teeth. [0002] The invention also relates to a method for gearing a wheel blank by hobbing, wherein the workpiece spindle, which receives the wheel blank to be geared internally, is driven in rotation and supports a cutting tool for a planing wheel with cutting teeth. The spindle is driven in rotation at a fixed rotational speed ratio relative to the workpiece spindle, and the planing wheel is advanced axially of the wheel blank by the relative movement of the tool spindle relative to the workpiece spindle. [0003] The invention also relates to a shaving wheel with a plurality of cutting teeth arranged in a gear-like arrangement about an axis of rotation. Background technique [0004] A dev...
