挤齿工艺有单轮、双轮和三轮挤压三种形式,在我厂生产中均有应用。在精度控制方面,以单轮最好,其余两种次之。这是因为挤轮的制造和装配都很难达到理想的精度以及调整困难之故。单轮受力情况不佳,作用力不能互相抵消,对机床的刚性要求较高。为了减小单轮挤齿时的作用力,在国外有的把挤轮的齿面做成和剃齿刀一样的带槽齿面,相邻同名齿面的沟槽互相错开,以保证齿轮齿面都受到同等机率的挤压。我厂的单轮挤压的挤轮没有开
Tooth extrusion technology has a single wheel, double wheel and three wheel extrusion in three forms, both in our factory production applications. In precision control, the best single wheel, the remaining two followed. This is because it is difficult to achieve the desired precision in the manufacture and assembly of crowded wheels and the difficulty of adjustment. Single-wheel force is not good, the force can not cancel each other, the rigidity of the machine requires a higher. In order to reduce the force when the single-wheel squeeze, in some foreign countries to squeeze the wheel gear made of the same gear and razor blade grooved face, adjacent to the tooth surface of the same groove offset each other to ensure that the gear teeth Face are subject to the same chance of squeezing. I plant a single squeeze squeeze wheel does not open
