Combined technology for milling and grinding tooth parts of spiral taper gear

Abstract

A grinding and abrading combined technology for machining the teeth of a pair of drive and driven spiral bevel gears includes such steps as forging, heat treating in advance, turning the raw teeth, grinding the primary locating position, milling spiral teeth, machining before heat treating (including tapping, chamfering and washing of driven gear and chamfering, milling spline and spiral threads and wash of drive gear, fine grinding, abrading between the drive and driven gears in a pair, and numbering them.

Description

Technical field:

[0001] The invention belongs to the gear processing technology, in particular to the processing technology for the tooth part of the spiral bevel gear used in the drive axle transmission of automobiles. Background technique:

[0002] The tooth processing technology of the driven wheel (referred to as "basin tooth") and driving wheel (referred to as "corner tooth") of the spiral bevel gear generally has the following three types. The wheels are respectively forged - pre-heat treatment - tooth blank turning - rough grinding of the main positioning part - helical tooth milling - pre-heat treatment processing (tapping, chamfering, cleaning of the driven wheel; driving wheel Chamfering, spline milling, thread milling, cleaning) - heat treatment - fine grinding (following wheel fine grinding inner hole and end face; driving wheel fine grinding main journal) - paired grinding and bruising - finished product pairing - storage. The second method adopts the process ...
