Forging Spur Gear

Hot Forging SAE1045 Precision Steel Spur Gear.



Products Performance is challenging to meet the requirements of transmission components withstanding cyclic loading and fatigue resistance in the long term. The traditional processing method of gears is made by forging blanks by hobbing, gear shaping, milling, planning, and other methods. This method has low material utilization, long processing time, high production cost, and has particular environmental pollution. The precision forging process can quickly produce high-quality gears, which solves many of the deficiencies of the traditional machining methods of gears and fully meets the requirements of gears against fatigue performance of long-term periodic loads during the transmission of power. Quantification and high intensity have produced a better impetus.

Forging is a method of machining mechanical parts or part blanks using a tool or die under the action of impact or pressure. Compared with other processing methods, the forging process has high productivity; the forged shape and dimensional stability are good and have the best comprehensive mechanical properties. The most significant advantages of forgings are high toughness, reasonable fiber structure, and small change in performance between pieces; the internal quality of forgings is related to the processing history and will not be exceeded by any metal processing technology.

Manufacturing Technology. There are many types of forging. Gear precision forging technology is one; the gear is called developing spur gear. Precision forging refers to gears whose teeth are directly obtained from the blank through precision forging. The tooth surface does not require cutting or only a small amount of finishing. Compared with the traditional cutting process, the gear precision forging process has the following characteristics:

1, Precision forging makes the fiber structure of metal materials uniformly and continuously distributed along with the tooth shape, refined grains and microstructures, and a few micro-defects. Therefore, the performance of precision forged gears is superior, and the bending strength, contact fatigue strength, and impact resistance of the teeth are significantly higher than cutting. Gear.

2, Improved production efficiency and material utilization. Through precision forging, the precision of the gear can reach the precision tolerance standard, and no or only a small amount of subsequent finishing is required. That is, it can be heat-treated or directly put into use, with high productivity and material utilization.

3, The precision-forged gear reduces the deformation of the tooth profile during heat treatment, improves the wear resistance of the teeth and the smoothness of the gear meshing, and improves the service life of the gear.
