Motorcycle Chain Manufacturers Introduce The Technology Of Gear Processing

Motorcycle Chain Manufacturers introduce the technology of gear processing.

1. Casting billet: hot die forging is still a widely used roughcasting process for car gears. In recent years, cross wedge rolling technology has been widely promoted in shaft processing. This skill is particularly suitable for the more complex stepped shaft blanks. It not only has high precision, small subsequent machining allowances, and high production efficiency.

2. Normalizing: The purpose of this process is to obtain the appropriate hardness of the subsequent gear cutting and prepare the structure for the final heat treatment, so as to effectively reduce the heat treatment deformation. The gear steel used is generally 20CrMnTi. Normal normalizing is greatly affected by personnel, equipment, and the environment, making it difficult to control the cooling rate and uniformity of the workpiece, resulting in large differences in hardness and uneven metallographic structure. Affect metal cutting and heat treatment, after all, making thermal deformation large and irregular, and the quality of parts cannot be controlled. For this reason, the isothermal normalizing process is selected. The practice has proved that the use of isothermal normalizing has effectively changed the shortcomings of normal normalizing, and the product quality is stable and reliable.
