四、变位係數的选擇方法变位係數选擇時,不但要能正確地选擇齒輪的变位係數,以提高齒輪的使用寿命,充分地發揮变位齒輪的优越性能;並且还要能計算簡捷,最好能有現成的圖表,以便設計時参考。目前,变位係數的选擇方法已有很多种,但是能完全符合上述选擇原则的方法,至今还几乎没有。今將目前較为通用的幾种变位係數的选择方法介紹如下: (1)苏联國家标準(2185-43)直齒圓柱齒輪变位係數选擇法这种变位係數的选擇方法,係由下列公式决定。
Fourth, the coefficient of choice choice Displacement coefficient selection, not only to be able to correctly select the gear displacement coefficient in order to improve the service life of gear, gear to give full play to the superior performance of the gear; but also to be able to Computation is simple, it is best to have ready-made charts, in order to design reference. At present, there are many ways to choose the coefficient of variation, but there are few methods to completely meet the above selection principle. Now some of the more common selection of the coefficient of variation are described below: (1) the Soviet Union National Standard (2185-43) spur gear selection method of displacement coefficient of this choice coefficient of variation, the Department The following formula to decide.
