The invention discloses a production method of an automobile gear. The production method of the automobile gear comprises the following steps of (S1) blank machining, specifically, normalizing treatment is performed on a gear forge piece blank, the inner circle, the outer circle and the two end surfaces of a gear ring are machined after normalizing treatment, chamfering is carried out on the two side edges of the outer circumference of the gear ring after the machining is completed, and then tooth-shaped rough machining is carried out on the gear ring. According to the production method of theautomobile gear and an automobile gear drilling device, the structure is compact, operation is convenient, the occupied space is small during use, and the gear punching operation can be carried out quickly and efficiently; the collection of scrap iron is facilitated due to the arrangement of a collecting tank; the position of the gear is conveniently fixed by combining a U-shaped supporting platewith a positioning stud; and the lifting adjustment of a motor is facilitated by the arrangement of a first hydraulic telescopic rod, an arc-shaped clamping plate can be pushed out by a second hydraulic telescopic rod, the gear can be supported and positioned by the arc-shaped clamping plate, a third hydraulic telescopic rod extends to push out a triangular clamping block, and the triangular clamping block can be used for clamping and positioning the gear.

The invention provides a gear processing technology for improving gear grinding efficiency. The gear processing technology comprises the steps that a tooth profile of a gear part is obtained from a blank through a hobbing or gear shaping technology; the gear deformation amount is calculated according to gear materials, sizes and an adopted heat treatment technology; according to the calculated deformation amount, the tooth surface of a gear is shaved by a gear shaving machine; the gear processed by shaving is subjected to a heat treatment process; and the gear obtained after heat treatment isfinished by a gear grinding machine. According to the gear processing technology for improving the gear grinding efficiency, the gear is subjected to heat treatment pretreatment according to the geardeformation amount by using the gear shaving technology, then heat treatment and gear grinding shaping are carried out, since the efficiency of the gear shaving process is 10 times or more of that ofgear grinding, the gear grinding efficiency can be significantly improved, and the machining accuracy and quality of the gear are ensured.
