Problems solved by technology

[0002] The axle ring gear tray is one of the important parts of the drive axle that must be equipped with vehicles with longitudinal engines. It belongs to disc parts and is equipped with inner holes. For heavy-duty vehicles with high power output for engineering, in order to adapt to the large torque of the transmission system and ensure the structural strength of the axle ring gear tray, the axle ring gear tray is generally designed to be relatively thick and the ring gear modulus is large. Technology Quenching treatment is generally used for heat treatment in the processing technology of axle ring gear trays. The defects are: the quenching depth and carburizing potential cannot meet the requirements, the surface hardness of the workpiece is low, and the wear resistance is poor. It is easy to wear and fail during use, and the service life short

Embodiment Construction

[0026] The axle ring gear tray processing technology in this embodiment includes blank preparation, rough machining, heat treatment, semi-finishing, finishing and product inspection, specifically including the following steps:

[0027] a. Blank preparation: purchase the forging blank and inspect the material, size and appearance of the forging blank;

[0028] b. Rough processing:

[0029] b1. Rough turning small outer circle, inner hole, and end face, reserve a machining allowance of 2~3mm, and the surface roughness of all surfaces reaches Ra12.5;

[0030] b2. The overall length of the rough car, the large stop and the outer circle of the teeth, reserve a machining allowance of 2~3mm, and the surface roughness of all surfaces reaches Ra12.5;

[0031] c. Heat treatment: Modulation treatment is adopted, the quenching and tempering hardness is 250-280HB, the modulation method is: heat the workpiece to 880 ° C ~ 900 ° C, keep it warm for 30 minutes, then carry out strong infiltra...
