When it comes to gear reducer, we must be not unfamiliar, gear reducer applied in all walks of life is an important part of the machine in all walks of life. The gear reducer is composed of what parts, the following by the precision gear manufacturer for you to explain.
1. Box body and box cover
The box body and the box cover are the support and inclusive parts of the transmission parts in the reducer. The structure is complex, and the box body bears the pressure and requires good steel degree, vibration damping and sealing. For box cover and body in small batch, grey cast iron (HTl 50 or HT 200), or carbon structural steel (Q235A), manual arc welding. In mass production, grey cast iron is used and cast by machine modeling method.

2, shaft, gear shaft and gear
Shaft, gear shaft and gear are all important transmission parts in reducer. The shaft and gear shaft have short bend and short twist, which requires good comprehensive mechanical properties; the teeth of gear shaft and gear are under large contact stress and bending stress, and shall have good wear resistance and high strength. For single production, medium carbon steel (45 steel) is formed by free forging method or tire die forging method, or cut by round steel bar of medium carbon steel. In mass production, medium carbon steel die forging method is adopted.

3. Rolling bearing
The rolling bearing in the reducer is subject to radial and axial compressive stress, which requires high strength and wear resistance. The rolling bearing is a standard part, and its inner and outer ring is forged by fluctuating bearing steel (GCrl 5), the ball is rolling bearing steel (GCrl 5) spiral inclined rolling, and the holder is made of high quality carbon structure steel (08 steel) stamping.

4. Bearing end cover
Bearing end cover is mainly to prevent the bearing movement, and play a protective role. For single piece and small batch of production, grey cast iron (HT 150) manual cast form, or carbon structural steel (Q235) round steel cutting. Mass production, using the grey cast iron machine shape casting forming.

5. Bolts and nuts
Bolts and nuts fix the box lid and box body, and the bolt rod is subject to longitudinal (axial) tensile stresses, bending stresses and transverse shear stresses. Bolts and nuts are standard parts, forged or squeezed from carbon cable structural steel (Q235A) pier.
