Abstract

The invention belongs to the technical field of gear machining and particularly discloses a machining process of the end faces of a gear. The process comprises the following steps of (1) forging; (2)normalizing, wherein forged pieces are subjected to normalizing treatment; (3) rough turning, wherein a large number of machining residues on the two end faces are removed, and preliminary molding ofthe two end faces is achieved; (4) finish turning, wherein finish turning is carried out on the two end faces in place, hard turning residues on the two end faces are reserved, and annular countersunkgrooves are formed in the two end faces through turning; (5) punching, wherein a plurality of through holes are formed in the annular countersunk grooves; (6) heat treatment, wherein carburizing andquenching are carried out; (7) shot blasting, wherein shot blasting is conducted on the forged pieces, the two end faces are cleaned, and the surface tissue and the surface strength are improved; (8)hard turning after heating, wherein hard turning is conducted on the two end faces in place, and the annular countersunk grooves are eliminated; (9) cleaning. According to the scheme, direct contact between a cutter and the through holes is avoided in the processes of rough turning, finish turning and hard turning, so that problems are avoided, the service life of the cutter is prolonged, there isno need to select the cutter with high hardness, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of gear processing, and in particular relates to a processing technology of a gear end face. Background technique [0002] For the main deceleration and driven gears, most of them now use screw-fixed connection structures, which usually require 8-12 positioning holes on the positioning surface, as well as a number of weight-reducing holes. Due to the relatively high requirements for the positioning end face, it is generally necessary to carry out the process of hard turning the end face after heat treatment. Due to the reasons for the positioning hole and the weight-reducing hole and the relatively high hardness (HRC58-62), during processing, each time the positioning hole or There will be a pause when the weight-reducing hole is used, and the end face of the gear cannot be processed continuously, but only intermittently, and the processing efficiency is very low; moreover, in order to prevent the tool from ...
