Problems solved by technology

[0002] The transmission shaft is a rotating body with high speed and few supports, so its dynamic balance is very important. Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and adjust it on the balancing machine. For a wheel-driven car, it is the shaft that transmits the rotation of the transmission to the final reducer. It can have several sections, and the sections can be connected by universal joints; some existing transmission shafts have relatively simple processing technology, and In the process of processing, the precise size cannot be guaranteed, and the efficiency is low; therefore, it is of great application significance to develop a high-precision process for high-speed drive shafts that can improve work efficiency, improve machining performance, and improve workpiece size accuracy.

Embodiment 1

[0042] A high-precision process for a high-speed transmission shaft, comprising the following steps:

[0043] 1) Material preparation: forgings;

[0044] 2) Rough turning: processing according to the process sketch;

[0045] 3) heat treatment;

[0046] 4) Finishing: clamp the φ50 outer circle at the right end, and align the outer circle at the left end and the F surface;

[0047] ①Grind 0.3~0.4 and surface A of the outer circle φG of the car to ensure that there is a margin in the total length, and the grate teeth will not be processed temporarily;

[0048] ②For the φF and F surfaces of the outer circle of the car, ensure that there is a margin on the E surface, and the grinding amount of the two outer circles is 0. 3 to 0. 4, and the 13. 5° inclined plane and the tooth are not processed temporarily;

[0049] ③ Drill M24 × 1. 5 bottom hole, φ 22. 5 deep 185 , inner hole φD grinding amount 0. 2 ~ 0. 3. φE will not be processed temporarily, φD hole finish chamfering 2 × 60°; ...
