Example Embodiment

[0083] The following is a detailed description of the 9-step process specific embodiments of the anti-fatigue manufacturing method of the curved bevel gear of the present invention with reference to the accompanying drawings:

[0084] 1. Press attached figure 1 The material for the given parts drawing of curved bevel gears is 42Cr2Mo, and the forging ratio should be ≥3, using one-time forming die forging process.

[0085] 2. After the blank is demolded, it enters the forging waste heat isothermal normalizing process, and its heat treatment process curve is in accordance with the attached figure 2 Process curve execution in zone I. The isothermal temperature of 42Cr2Mo steel is 680 ±5 ℃, the hardness value is 180~190HB, the average grain size is 6 grade.

[0086] 3. After the rough turning of the tooth blank, it is transferred to the fine turning of the CNC lathe to meet the technological requirements.

[0087] 4. The tooth blank is semi-finished at the tooth feeding part on the lar...

Abstract

The invention relates to a novel composite surface-enhanced spiral bevel gear production process system based on a current anti-fatigue manufacturing method system and integrating induction quenching and gas nitriding. The invention aims to provide a composite surface-enhanced cyclo-palloid spiral bevel gear manufacturing method with heated precision of 4 to 6 levels and achieving the purpose that the theory contact zone meshed strength is meshed with carburizing and quenching strength. The invention aims to further provide a new spiral bevel gear production technology which can not only embody the current anti-fatigue high-end gear manufacturing method purpose, but also agree with the complete software and hardware match of a roadmap of heat treatment technology development in China.

Description

technical field [0001] The invention belongs to a gear manufacturing method, in particular to an anti-fatigue manufacturing method of a curved bevel gear. Background technique [0002] In the existing technology, due to the urgent need for long-life and high-reliability gears in high-end fields such as aviation, aerospace, automobiles, wind power, high-speed rail, and ships, people started from the reverse thinking of anti-fatigue and proposed and constructed a gear based on material technology. The core is a gear anti-fatigue manufacturing method system that uses heat treatment as a means to obtain quantitative indicators of high fatigue performance. [0003] In the prior art, although the production technology of curved bevel gears has gone through a hundred years, in actual production, especially in the field of the automobile industry, which uses the largest number of curved bevel gears, its manufacturing method still stays in the forming and manufacturing stage. The sa...
