What are the processes for gear machining in Shenyang?

1. Casting and forging still remain widely used blank casting processes for automotive gear components. In recent years, wedge rolling technology has been extensively promoted in the processing of shaft components. This technology is particularly suitable for producing complex stepped shafts, as it not only offers high precision and small machining allowances but also has high production efficiency. 2. Normalizing The purpose of this process is to achieve a hardness suitable for subsequent gear cutting processing and to prepare the structure for final heat treatment, effectively reducing thermal deformation during heat treatment. The gear steel material used is generally 20CrMnTi. Normalizing is significantly affected by personnel, equipment, and environmental factors, making it difficult to control the cooling rate and uniformity of the workpiece, resulting in large hardness variations and uneven metallographic structures, which directly affect metal cutting processing and final heat treatment, leading to significant and irregular thermal deformation, making it difficult to control the quality of the parts. Therefore, isothermal normalizing technology is adopted. Practical experience has shown that isothermal normalizing effectively addresses the shortcomings of conventional normalizing, resulting in stable and reliable product quality. The basic requirement for cage design is to meet the maximum load capacity and rotational precision and speed of the bearing within a certain space and structural strength. The guiding method for the inner and outer diameters or rolling elements can be determined based on the operating conditions of the bearing in the main machine and the requirements for guiding clearance, thus confirming the structure and main parameters. When rolling bearings operate, heat and wear are generated due to sliding friction, especially under high-speed conditions. The effects of centrifugal force and inertial force accelerate the collision and friction wear and heating of the rolling elements, inner and outer rings, and cage. In severe cases, this can lead to cage burning and cracking, causing the bearing to fail to operate normally. Cage damage accounts for a significant proportion of bearing failure modes, and the quality of the cage material is one of the main reasons for cage damage. Therefore, the material for bearing cages is required to have excellent mechanical strength, dimensional stability, and outstanding plasticity and machinability, among other functions.
