Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is further described;

[0021] A ring gear bracket processing technology, the processing technology includes the following steps:

[0022] 1) Rough inspection:

[0023] 2) Rough turning: a. The outer circle of the big head of the three-jaw clamp, the size of each gear of the small head of the rough turning, pay attention to the rough turning with the upper notch surface of the blank as the rough reference to distribute the rough turning allowance to both sides, and the spindle speed is 250r / min , the feed rate is 0.3mm / r; b, the U-turn clamp is the inner hole of the small head, and the dimensions of each gear of the large head are roughed (note that the error of the two clampings is not greater than 0.4mm), and the spindle speed is 250r / min, and the feed rate is 0.3mm / r; c, deburring, inspection, qualified storage.

[0024] 3) Quenched and tempered shot blasting: a. Quenched and tempered: 25~30HRC,...

Abstract

The invention provides a gear ring support machining technique. The machining technique comprises the following steps of (1) blank detection, (2) rough turning, (3), tempering and shot blasting, (4) semi-extractive turning, (5) quenching, (6) gear broaching, (7) large end face and groove turning, (8) hole drilling and notch milling, (9) hobbing, (10) orifice chamfering, and (11) cleaning and packaging. The machining technique of an inner gear ring is simple in procedure, the hardness of an obtained gear ring support is high and can reach 700-850 HV, the effective hardness depth can reach 0.50 mm, the precision is high, and the abrasion resistance is good.

Description

technical field [0001] The invention relates to a ring gear bracket processing technology, which belongs to the technical field of mechanical processing. Background technique [0002] The ring gear is a key component used in the transmission system for transmission and transmission functions. It is composed of a flange half coupling with external teeth and an inner ring gear with the same number of teeth. It is mainly used to start the motor transmission system, and it has the function of transmission and transmission according to the meshing rotation of the metal teeth. The use of the ring gear bracket is very large, and the processing technology of the ring gear bracket generally includes the following steps: blank forging - blank detection - quenching and tempering treatment - lathe processing - gear hobbing - drilling - quenching treatment - Flaw detection - high temperature tempering - testing - packaging. The existing processing technology consumes a lot of raw mater...
