High Precision Differential Spider Gear Kit 346 353 0420 Long Using Life

Our Advantages

Raw Material
20Cr, 20CrMnti steel, from the domestic first-class steel mills(Shigang, Huaifang etc),
Normal A3 material, or from the scrap board
First-class steel mills, quality is satble.
20Cr, 20CrMnTi, be stable and high torque strength under high speed.

Forging
Using the domestic advanced forging technology, cross-shaft oil groove forging at one time.
Using rough forging oil tank, and then processing oil tank.
Use domestic advanced forging oil tank technology, and access to domestic advanced patent certificate;
One-time precision forging oil tank, can prevent re-processing cracks, increase product life, the use of the process is not easy to be broken.

Heat Treatment
Use the domestic advanced mesh belt furnace treatment and computer-controlled quenching process, and use international (Kunlun) quenching liquid.
Normal ordinary pit furnace to do heat treatment, or use cold water.
Make sure the product is not easy to deformation and the balance of vertical;
Stable operation, uniform heating to ensure that the product hardness and carburizing layer;
Oil quenching and annealing can ensure the flexibility of the product without easy to be damaged.

Product Testing
Use advanced magnetic particle testing equipment, the finished product differential cross shaft detection.
None
Use domestic advanced heat treatment equipment and processing technology, the product is not easy to deformation, to ensure that the product of the balance of vertical.

Stable operation, heating evenly to ensure that the product hardness and carburizing layer.

Oil quenching can ensure product flexibility.
