在风动手工具类产品上,常采用行星轮系减速。在这种减速机构中,都有一个内齿轮零件(如图1)。过去,一直沿用传统的插齿刀在插齿机上加工。这种插齿法生产效率低,工件的表面质量与操作者的技术水平有一定联系,远远不能满足生产飞速发展的要求,成为生产中的一个薄弱环节。我们研究决定改变这种加工方法,采用拉削加工。拉削加工生产效率高,比插齿法高十余倍甚至数十倍,加工质量稳定,零件精度决定于刀具精度,与操
In the pneumatic hand tools, planetary gear train is often used to slow down. In this deceleration mechanism, there is an internal gear parts (Figure 1). In the past, traditional shaper cutters have been used to machine shaper machines. The low efficiency of this gear generation method, the surface quality of the workpiece and the technical level of the operator have a certain connection, far from meeting the requirements of the rapid development of production has become a weak link in the production. We study the decision to change this processing method, the use of broaching. Broaching production of high efficiency, more than ten times the gear shaper or even a few times, processing quality and stability, parts accuracy depends on the accuracy of the tool, and operation
