我厂生产的手扶拖拉机的转向轴,其上有三角形花键齿。最初采用成型铣刀在铣床上加工,生产率低,后改用滚轮在液压滚丝机上滚压成型。滚轮设计是参照有关资料设计的,滚压中废品率太高,长期得不到解决。后对滚轮的设计进行了改进,使废品率大大降低,收到了很好的效果,现将滚轮的设计原理及没计步骤介绍如下。 I plant the walking tractor steering shaft, which has triangular spline teeth. The first use of milling cutter in milling machine processing, low productivity, after the switch to the roller rolling machine in the hydraulic roll forming. Roller design is based on the design of the information, the rolling rate is too high, long-term can not be resolved. After the design of the wheel has been improved so that the rejection rate is greatly reduced, received a very good effect, now the wheel design principles and no steps are described below.
