Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it is not intended to limit the protection scope of the present invention.

[0017] A processing method for improving the contact quality of the bevel gear pair of the K series reducer. The specific steps are as follows: the method of pre-adjusting the contact area is adopted, and the relevant parameters are pre-adjusted before the heat treatment, taking into account the tooth shape change rule after heat treatment. The eccentric angle is reduced by 20 minutes, so that the heat-treated tooth profile is in the ideal position on the tooth surface. The processing method can effectively modify the tooth surface contact area and improve the contact quality. The noise of the bevel gear pair processed by this processing method is 2-4db lower than that of the bevel gear pair processed by the traditional method of grinding and correcting the contact area. After usi...

Abstract

The invention belongs to the field of bevel gear pair deep processing, and especially relates to a processing method capable of improving the contact quality of a bevel gear pair of a K series speed reducer. According to the method, a contact area pre-adjusting method is adopted, an after-heat-treatment tooth shape change rule is taken into account; related parameters are adjusted in advance before a heat treatment; and the eccentric angle is reduced by 1/3 degree so that a tooth shape is arranged on an ideal position of a tooth surface after the heat treatment. The change rule of a contact area of a K series speed reducer is researched before and after a heat treatment, wherein the gear ratio of the bevel gear pair of the K series speed reducer is 8:33. The contact area is corrected in advance so as to improve the contact quality. The tooth surface contact area is effectively corrected, and the noise is reduced.

Description

technical field [0001] The invention belongs to the field of deep processing of bevel gear pairs, and in particular relates to a processing method for improving the contact quality of bevel gear pairs of K series reducers. Background technique [0002] Under normal meshing operation conditions of a pair of bevel gear pairs, the actual contact part on the tooth surface is commonly called "contact area", also known as "contact spot". There is a direct impact, so the contact area of ​​the tooth surface becomes one of the important signs to measure the meshing quality of the bevel gear. In the GB11365-89 bevel gear accuracy standard, different requirements are put forward for the contact area of ​​gears with different accuracy grades. In the ISO17485-2009 bevel gear accuracy standard, the quality of the contact area is not related to the accuracy grade, but according to the processing practice Experience and customer requirements to meet end use are used as the basis for judgin...
