Short Description:

This spur gear shaft used in construction machinery .  Gear shafts in transmission machinery are usually made of 45 steel in high-quality carbon steel, 40Cr, 20CrMnTi in alloy steel, etc. Generally, it meets the strength requirements of the material, and the wear resistance is good. This spur gear shaft was made by 20MnCr5 low carbon alloy steel ,carburizing into 58-62HRC.


Product Detail

Product Tags

The spur gear shaft is the most important supporting and rotating part in construction machinery, which can realize the rotary motion of gears and other components, and can transmit torque and power over a long distance. It has the advantages of high transmission efficiency, long service life and compact structure. It has been widely used and has become one of the basic parts of construction machinery transmission. At present, with the rapid development of the domestic economy and the expansion of infrastructure, there will be a new wave of demand for construction machinery. The material selection of the gear shaft, the way of heat treatment, the installation and adjustment of the machining fixture, the hobbing process parameters, and the feed are all very important to the processing quality and life of the gear shaft.
