Precision forging process and die design of spur bevel gear

Spur bevel gears are widely used in the differentials of automobiles, tractors, motorcycles, tanks and other walking machinery. They have a wide range of applications, large demand and easy wear. Using traditional machining method to produce spur bevel gear has the advantages of slow speed, low efficiency and poor...

Tooth profile design of bevel gear hot forging

The tooth profile of hot forging bevel gear is the basis for designing and inspecting the tooth profile of die cavity. It is obtained by considering the thermal expansion of forgings. According to whether the temperature field in the forging is uniform at the end of forging, the thermal...

Design of precision forging die for spur bevel gear

When forming spur bevel gears by “one fire and two forging”, the surface of the die cavity is in direct contact with the high-temperature gear blank. After the forgings bear high thermal load are out of the die, they need to use water-soluble graphite to cool and lubricate the...

Forging design of planetary gear and half shaft gear

Fig. 1 shows the forging drawing of planetary gear and half shaft gear. When formulating the forging drawing of bevel gear, the following aspects should be considered: (1) When determining the parting surface of open die forging bevel gear, the parting surface is composed of back cone parting surface...

Elastic mechanics method for strength analysis of spur gears

Because the “cantilever beam” model is quite different from the real spur gear, the material mechanics method is difficult to truly reflect the influence of complex tooth profile and transmission system on the strength and deformation of spur gear. According to the plane elasticity theory, many scholars apply appropriate...

Numerical simulation of precision forging of spur bevel gear

Gear is an important part widely used in automobile, machinery, aerospace and other industries. Gears processed by precision die forging process can be directly used due to good surface quality and high dimensional accuracy without subsequent cutting, which greatly improves the material utilization and production efficiency and reduces the...
