采用变位齿轮,可不必附加任何材料消耗和复杂的工艺过程,亦不需专用的设备和刀具,即能提高齿轮的接触强度和弯曲强度,减少轮齿的“点蚀”和磨损,以及解决一系列的几何设计问题。但为了完满地达到上述要求,设计者必须选出最合理的变位系数。为此,要求设计变位齿轮时应该验算有关的参数(如齿顶厚度、 The use of variable gear, without having to add any material consumption and complex process, and without special equipment and tools, which can improve the contact strength and bending strength of the gear to reduce gear “pitting” and wear and tear, As well as solve a series of geometric design problems. However, in order to fully meet the above requirements, the designer must select the most reasonable coefficient of variation. To this end, the design requirements of gears should be checked when the relevant parameters (such as tooth top thickness,
