Vehicle drive axle spiral bevel gear near net shape forging

Projects

First: Application and market capacity of Spiral bevel gear Vehicle drive axle spiral bevel gear have two part : the main and

passive gear, known as bevel gear, as a set.

Application:

1. to change the direction of the torque transfer

2 .decelerating growth from role

Market Capacity: According to Chinese pots angle gear market research report

in 2013,Expect 2014-2015, basin angle gear market capacity up to 10 million units/year,Loading and accessories market is about 50% each.

Second, spiral bevel gear technology situation in China and on abroadExisting processes:

General forging Isothermal normalizing Turning, drilling

Full gear early cut Fine pulling teeth Carburizing

With research

Disadvantage of existing process :

1.low intensity, short life

2. high energy consumption, supplies

3.Final heat deformation, high rejection rate

4.High cost of machining

Third,characteristics and advantages of near-net shape forging process sprial bevel gear 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

Advantage of forged teeth bevel gear

1. Will keep the whole mental flow line, life span increases 70%.

2. Lower 20% cost material , heating and isothermal normalizing.

3. Lower machining allowance and high precision.

Forged teeth crown wheel,analysis from AAM.

Lianda bevel gear 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 spiral bevel gear 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 Lianda and will reach 150,000 units of production capacity during the year.

Lianda bevel forged teeth processing

1.Owned ISO9001:2008 and TS 16949

2. Material and size accept customed

3. Will keep the whole mental flow line, life span increases 70%

4. Lower machining allowance and high precision

5. Price a little different with general blank type

Fouth:Process advantages

After forging teeth , ensuring the integrity of the metal flow lines, improving strength, after proveing, life expectancy increased more than 70%.

Saving material 15-20%, while saving 15-20% costs of heating and forging isothermal normalizing .

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%. .

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