addendum coefficient meaning in Chinese

齿顶高系数

2 . the long - addendum coefficient of pump gear must make the gear in the condition of undercut . base on these conclusions , the basic parameters of pump gear are optimum
本文提供了完整的泵齿轮最佳参数的计算公式，计算方法既能使泵齿轮参数达到最佳，而且计算简单，工艺性也较好。
After thoroughly analyzing the influence of each pump parameters on the gear pump performance , the paper developes the criterion for optimum gear parameters , which can be utilizied in practice easily for gear manufacturing using normal involute gear hob with two - fillet type . the conclutions studied by the paper are : 1 . both the addendum coefficient and the deddendum coefficient of the pump gear should be 1 . 125
以目前国内普遍使用的双圆弧头全齿高为2 . 5倍模数渐开线标准滚刀作为泵齿轮的加工刀具，通过对齿轮加工原理的分析，提出了欲使泵齿轮参数达到最佳，泵齿轮的齿顶高系数和齿根高系数都为1 . 125 ；对变位系数的确定应考虑到泵齿轮的根切、齿顶厚、重合度以及侧隙因素；泵齿轮为避免过渡曲线干涉，必然要存在根切现象。
