我厂在测绘国外高压齿轮泵时,发现该泵所用的齿轮是双模数、双压力角非对称型齿轮。据有关资料报道,这种齿轮泵是国外七十年代末和八十年代初才开始发展起来的新型结构齿轮泵,它与普通高压齿轮泵相比,在不增加齿轮泵的体积条件下,增加了泵的排量,减少了脉动,降低了噪音,增加了平稳性,提高了效率,是值得推广的一种新型结构。非对称齿形的加工和刀具设计目前尚无专著介绍。作者根据齿轮展成原理,参考对称齿形齿轮加工刀具设计原理,设计了非对称齿形齿轮滚刀,经使用证明达到设计要求。设计计算过程如下。
I plant in the mapping of foreign high-pressure gear pump and found that the pump gear used is a double modulus, double pressure angle asymmetric gear. According to the information reported, this kind of gear pump is a new type of structural gear pump that began to develop in the late 1970s and early 1980s. Compared with the ordinary high-pressure gear pump, the gear pump is increased without increasing the volume of the gear pump The pump displacement, reducing the pulsation, reducing noise, increased stability, increased efficiency, is worth promoting a new structure. Asymmetric tooth processing and tool design there is no monograph. According to the principle of gear development, the author designs the asymmetrical gear hob with reference to the design principle of the symmetrical gear tooth cutting tool, which has been proved to meet the design requirements by using. Design calculation process is as follows.
