Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] see figure 1 , figure 2 , image 3 and Figure 4 , described a kind of helical bevel gear hard tooth surface milling method, its steps are as follows:

[0019] The first step is to process the spiral bevel gear blank 2, which is carried out on the spiral bevel gear milling machine. The spiral bevel gear blank will be made with 20CrMnTi or 20CrMnMo, the meshing coloring and the length direction of the meshing surface should be controlled to account for 50% ± 10%. The surface height direction accounts for 70% ± 10%, and the tooth thickness reserves 0.2 ~ 0.3mm allowance;

[0020] The second step is to increase the angle of relief on the tip of the milling cutter head, and it is carried out on the spiral bevel gear milling machine to process the effective angle of relief for the tooth root of the spiral bevel gear blank (see image 3 );

[0021] The third st...

Abstract

The invention relates to a method for milling a hardened gear surface of a spiral bevel gear. The method includes the steps of firstly, processing a spiral bevel gear blank; secondly, processing a cutter relieving contact angle; thirdly, performing heat treatment; fourthly, subjecting a gear ring to hole grinding on an inner hole grinding machine; fifthly, milling the hardened gear surface; sixthly, using a bevel gear lapping machine to grind a gear surface of a processed gear; and seventhly, checking a finished product. The method for milling the hardened gear surface of the spiral bevel gear is capable of guaranteeing high accuracy of the spiral bevel gear, improving production efficiencies and reducing manufacturing costs.

Description

technical field [0001] The invention relates to a gear processing method, in particular to a method for milling a hard tooth surface of a spiral bevel gear. In the method, milling is used instead of grinding, which improves production efficiency and reduces manufacturing costs. Background technique [0002] Due to the rapid development of my country's gear industry, the market demand for spiral bevel gears has increased, and the quality and accuracy requirements for spiral bevel gears have also continued to increase. However, at present, high-precision spiral bevel gears are mainly processed by imported spiral bevel gear grinding machines. As a result, its processing cost is very high and its efficiency is extremely low. Therefore, exploring new processing methods to improve the quality and accuracy of spiral bevel gears, expand production capacity, improve production efficiency, and meet the ever-increasing market demand has become a top priority for the gear industry. Con...
