Construction Machinery Gear

PRODUCT PARAMETERS:

Zhejiang engineering machinery gear refers to a gear on the rim of the continuous mesh transmission of motion and power of the mechanical components. The application of gear in transmission appeared very early, and with the development of production, the smoothness of gear operation has been paid attention to. The commonly used steels for manufacturing Zhejiang construction machinery gear are tempered steel, quenched steel, carburized quenched steel and nitriding steel. The strength of cast steel is slightly lower than that of forged steel, and it is often used for larger gears. Gray cast iron has poor mechanical properties and can be used in light-load open gear transmission. Ductile iron can partially replace steel in gear manufacturing. Plastic gears are mostly used in places with light load and low noise requirements, and the gear paired with it is generally made of steel gear with good thermal conductivity. In the future, Zhejiang construction machinery gear is developing in the direction of heavy load, high speed, high precision and good efficiency, and strive to be small in size, light in weight, long in life and economical and reliable.
