Problems solved by technology
[0003] The requirement for the intermediate shaft to be two helical gears is that the positions of the tooth grooves on the first gear and the second gear correspond to each other, which makes the teeth on the first gear and the second gear It is very difficult for the tooth grooves to correspond to each other, and there is no ready-made processing technology that can be used. Therefore, a new method is needed to complete the alignment to meet the design requirements

Embodiment Construction
[0025] The process of preparing the intermediate shaft A with counter teeth is: forging → rough turning → normalizing → finishing turning → rolling out the first helical gear 1 → rolling out the second helical gear 2 → chamfering → heat treatment → grinding the outer end surface → Grind the first helical gear 1 → Grind the first helical gear 1 → put the finished product into storage. After rolling out the first helical gear 1 and before rolling out the second helical gear 2, it is necessary to use the following method to make the tooth grooves of the second helical gear 2 correspond to the tooth grooves on the first helical gear 1. The tooth space on 1 is used as a reference to determine the tooth space of the second helical gear 2 to be processed:
[0026] Such as Figure 1 to Figure 3 As shown, the method for hobbing the helical teeth of the intermediate shaft of the present invention includes the following steps:
[0027] Step 1. The first helical gear 1 is obtained by hobbing...

The invention discloses a gear hobbing method for intermediate shaft helical tooth alignment. A first section line of a first helical gear is scribed along the circumferential face of the first helical gear, a second section line is scribed at the position, where a second helical gear is to be machined, on an intermediate shaft, and the first section line is intersected with a first gear groove notch to obtain a first intersection point and a second intersection point; a height gauge is used for conducting scribing on the position, where the second helical gear is to be machined, on the intermediate shaft, the line is intersected with the second section line, and a third intersection point is obtained; the height gauge is used for conducting scribing on the position, where the second helical gear is to be machined, on the intermediate shaft, the line is intersection with the second section line, and a fourth intersection point is obtained; the height gauge is used for conducting centerline scribing on the position, where the second helical gear is to be machined, on the intermediate shaft, and the third intersection point and the fourth intersection point are symmetric about the center line; and the third intersection point, the fourth intersection point and the center line are adopted as the gear hobbing standard, and the second helical gear is obtained at the position, wherethe second helical gear is to be machined, on the intermediate shaft through gear hobbing. The gear hobbing method has the beneficial effects that the process is simple, and the machining period is short.
Description
Technical field [0001] The invention relates to the technical field of gear-to-tooth processing on an intermediate shaft, and in particular to a gear hobbing method for helical gear-to-tooth processing of an intermediate shaft. Background technique [0002] The counter-tooth first gear and the second gear with the first gear and the second gear on the counter shaft of the existing transmission assembly are formed by hobbing. The counter-tooth on the existing counter shaft is a straight tooth structure. This kind of straight tooth machining technology is very mature. However, for the transmission needs, it is necessary to design a method so that the gear teeth on the first gear and the second gear on the intermediate shaft are helical teeth, the helix angle β1 of the first gear is left-handed, and the helix angle β2 of the second gear is left-handed . [0003] The requirement for the intermediate shaft to be two helical gears is: the cogging positions on the first gear and the sec...
