Example Embodiment

[0010] The present invention will be further described below in conjunction with the drawings and specific embodiments to help understand the content of the present invention.

[0011] As shown in Figure 1, it is a schematic diagram of the gear tooth surface finishing device. It includes a first gear support shaft 1 mounted with a shaving cutter 4, a second gear support shaft 2 for mounting a gear 5 to be machined, and a third gear support shaft 3 mounted with a standard gear 6 to make the gear 5 to be machined It is meshed with the standard gear 6 and the shaving cutter 4. A mesh insulation layer (omitted in the figure) with a thickness of about 0.2mm is uniformly arranged on the standard gear 6 so that the metal surfaces of the two will not directly contact to avoid short circuits. It can also pass through the electrolyte. The first gear support shaft 1 is the driving shaft, the second gear support shaft 2 and the third gear support shaft 3 are driven shafts; the second gear sup...

Abstract

The invention discloses an electrolysis exquisite processing method of gear surface, which is characterized in that the convex part of the gear surface after heat treatment is passivated to reduce the hardness through electrolysis processing. The passivated part is processed by a gear shaving knife through the gear shaving processing. The invention also discloses a processing device. The method can remarkably improve the exquisite processing efficiency and quality and reduce the processing cost, therefore, the invention is in particular applicable to exquisite processing of small modulus gear.

Description

technical field [0001] The invention relates to a processing method of a gear tooth surface, a method for auxiliary processing of a gear tooth surface by electrolysis, and a processing device. Background technique [0002] At present, the commonly used gear processing methods are: gear hobbing and gear shaping processing. The processing accuracy (GB10095-2001) reaches 7-8 grades, and then 6-7 grades can be achieved through shaving. Since the gear needs to be heat treated after the shaving process is completed, the accuracy grade of the gear tooth surface after heat treatment will usually drop by 1 to 2 grades with the thermal deformation. For finishing, the usual finishing method is to grind the hard tooth surface of the gear, but the cost of grinding the gear is high, and it is difficult to do the grinding of the small modulus gear, resulting in low production efficiency of the gear and making the processing higher cost. Contents of the invention [0003] In view of the...
