Problems solved by technology

In order to avoid the formation of secondary burrs, it is also possible to resharpen the cutting edges of the deburring tool more frequently, however, especially since an intervention must always be carried out sufficiently early before secondary burrs start to form, which is associated with time and cost expenditures Associated

Embodiment Construction

[0039] exist Figures 1A to 1C A schematic perspective view of a bevel gear 10 is shown in , wherein the basic steps of the invention will be explained on the basis of these three figures. The elements and terminology used in this document are also based on Figures 1A to 1C to define.

[0040]In the mentioned figure only a part of the main body of the bevel pinion 10 can be seen in schematic form. A single tooth gap 14 is represented in the material of the body. The example shown is a bevel gear 10 with curved tooth flank longitudinal lines, as can be seen from the profiles of the teeth 15.r and 15.l. However, the invention can also be applied to other bevel gears 10 . In the example shown, the bevel pinion 10 has a body defined by two frusto-cones with corresponding conical side surfaces. Precisely, these conical side surfaces are frusto-conical side surfaces. The two truncated cones are arranged coaxially with respect to the workpiece spindle axis B. The workpiece sp...

Abstract

The invention relates to a bevel gear cutting machine and method for chamfering bevel gear tooth edges. A bevel gear cutting machine (200) having multiple numerically-controllable axes includes a workpiece spindle (205), which accommodates a bevel gear (10) coaxially in relation to a workpiece spindle axis (B), and a deburring device (50) having a deburring spindle (51) for accommodating at leastone first deburring tool (60). The bevel gear cutting machine (200) may chamfer tooth edges of the bevel gear (10) in two passes, where, in a first pass, first chamfers are provided on the tooth edgesby using the first deburring tool (60), and, in a second pass, second chamfers are provided in the region of the first chamfers by using the first deburring tool (60) or by using a second deburring tool in a continuous procedure, in which the bevel gear (10) and the first or second deburring tool (60) rotate in a coupled manner while engaged with one another.

Description

technical field [0001] The present invention relates to a bevel gear cutting machine and to chamfering the tooth edges of bevel gears in a continuous process. The invention also relates to a method for chamfering the tooth edges of bevel gears. Background technique [0002] In the manufacture of bevel gears, burrs (herein also referred to as primary burrs) are generated, for example, at the ends of the outer teeth due to cutting work. Due to the high risk of injury and due to the risk of complete hardening of the bevel gear during hardening, these tooth edges are often removed by chamfering in the area of ​​the chamfering. [0003] During the described chamfering process, depending on the configuration, secondary burrs are produced on the bevel gear during the removal of the primary burr. If the primary deburring is performed with a deburring tool, the cutting edge of the deburring tool is guided outwards from the tooth gap, thus creating a secondary burr on the outer circ...
