Gear ring processing method

Abstract

The invention relates to a gear ring processing method, which is characterized by comprising the steps of: firstly, carrying out carburization prevention treatment on a welding line part of a slave cylindrical gear and neighboring surfaces thereof, positioning and clamping a gear ring on a welding end face of a carburization-free layer of the slave cylindrical gear by adopting a special clamp as required, and carrying out laser welding on the gear ring and the slave cylindrical gear by using a titling-type numerical control rotary table and a light guide system of a reflection type focusing structure; wherein 3-11 short welding lines are discontinuously and uniformly distributed along a gear ring welding circumference, each welding line is 2-15mm in length, 0.5-2mm in width and 2-8mm in weld penetration. In the invention, the laser cutting precision on an ABS (Acrylonitrile Butadiene Styrene) gear ring is high, the ABS gear ring is welded on a cylindrical gear through laser, the connection strength is high, the influence of welding heat is low and the deformation is small; and the entire system has compact structure and light weight, is simple and reliable, is easy for the arrangement of the whole machine and free of maintenance, and can prevent gear ring from falling.

Description

technical field [0001] The present invention relates to a ring gear processing method, in particular to an automotive portal drive axle or portal steering drive axle (including independent suspension and non-independent suspension) built-in ABS ring gear and driven cylindrical gear through laser welding A connection method; belongs to the technical field of laser welding. Background technique [0002] Due to the limited space, the ABS ring gear and the driven cylindrical gear cannot be manufactured in an integrated structure, and can only be manufactured separately and then connected into one. The wall of the ABS ring gear is thin, and the area of ​​the connecting part with the gear is narrow , It is very difficult to ensure the reliable connection between the ABS ring gear and the gear, high precision, and small deformation, which cannot be realized by conventional processes. Contents of the invention [0003] The purpose of the present invention is to provide a method f...
