Crown wheel pinion gear set technology situation in China and on abroad

Existing processes:

General forging Isothermal normalizing Turning, drilling

Full gear early cut Fine pulling teeth Carburizing

With research

Characteristics and advantages of near-net shape forging process crown wheel pinion gear set

Forging process ：

Forging (forging tooth) Isothermal normalizing Turning, drilling After forging tooth in the case of a very small portion of the initial allowance incisor Fine pulling teeth Carburizing With research

Process advantages

After forging teeth, ensuring the integrity of the metal flow lines, improving strength, after proveing, life expectancy increased more than 70%. 精 后 形保 了完整的金属流 ，强度提高， ，齿轮 锻 齿 证 线 经验证寿命提高 70% 以上。

Saving material 15-20%, while saving 15-20% costs of heating and forging isothermal normalizing. 精 后 原材料锻 节约 15~20% ，同 造加时节约锻

和等温正火加 用的热 热费 15~20% 。

After precision forging,compared with the traditional process,tooth surface allowance is minimal,cutting residual stress is almost negligible. Subsequent heat deformation small, the yield increase 1-3%. 精 后 面锻 齿加工余量 小，切削残余 力与 工 相比，几乎可以忽略不 。极 应 传统 艺 计后 理 形小，成品率提高续热处 变 1~3% 。

After precision forging, cutting teeth on the high-speed gear cutting machine, high efficiency and low cost of parts.

Project1.The project participants and the division

Henan University of Science and Technology, led by Deng allegiance to the president's team of experts in charge of manufacturing technology research and production and some critical equipment.

Anyang Forging Press Machinery Industry Co., Ltd. is responsible for forging equipment manufacturing.

Anyang Lianda CNC Precision Forging Co,Ltd responsible for product testing and production.

Asia‘s largest manufacturer of crown wheel pinion gear set Zhuzhou gear company has signed underwriting agreement with Lianda company and spread the final products to the domestic and international markets together

2.the project has already started in the company and will reach 150,000 units of production capacity during the year.
