Example Embodiment

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

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

[0028] b. Roughing:

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

[0030] b2. The total length of the roughing, the large spigot and the outer circle of the tooth, reserve a machining allowance of 2~3mm, and the total surface roughness reaches Ra12.5;

[0031] c. Heat treatment: adopt modulating treatment, quenching and tempering hardness is 250-280HB, modulating method is: heat the workpiece to 880℃~900℃, hold for 30 minutes and then carry out infiltration for 3 hours, the carbon potential is 0.4, then the temperature drops to 860℃ ...

Abstract

The invention discloses an axle gear ring tray machining process which includes blank preparation, rough machining, heat treatment, semi-finishing, finish machining and product inspection. The heat treatment adopts thermal refining treatment, so that machined axle gear ring trays can be high in surface hardness and abrasion resistance, and the service life of the machined axle gear ring trays can be prolonged.

Description

technical field [0001] The invention relates to a processing technology for auto parts, in particular to a processing technology for an axle ring gear tray. Background technique [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 wea...
