用硬质合金滚刀高速滚削钢齿轮,由于滚刀经常崩刃以及价格昂贵等原因,使得在实际使用中受到很大限制。但在近两年来,已采用一系列的措施来保证在高速滚齿时避免刀齿崩刃和提高加工稳定性。其中,首先是研制了一种高刚性的特殊耐振设备,以及采用了特殊细颗粒的硬质合金作滚刀材料,本文介绍有关这方面的一些研究结果。硬质合金滚刀滚削钢制齿轮时,动态重负荷周期地作用在滚刀切削刃上。这种负荷随着切削速度的提高而增大。因此,减弱滚刀齿的冲击和减小切削时的振动是设计这种设备的基 With carbide hob hobbing high-speed steel gear, the hob often chipping as well as expensive and other reasons, making the actual use of a great restriction. However, in the past two years, a series of measures have been taken to ensure that cutting teeth do not collapse and improve the processing stability during high-speed gear hobbing. Among them, the first is to develop a special high-rigidity vibration-resistant equipment, as well as the use of special fine-grained carbide for hob material, this article describes some of the findings in this regard. Carbide hob hobbing steel gear, the dynamic load on the hob cycle cutting edge. This load increases with the cutting speed. Therefore, reducing the impact of hob teeth and cutting vibration is the basis for the design of such equipment
