摘　　要：利用有限元方法计算分析了余弦齿轮的轮齿刚度,并将计算结果与相应的渐开线齿轮进行比较,结果表明余弦齿轮的轮齿刚度要高于相应的渐开线齿轮。在此基础上,分析了余弦齿轮设计参数对轮齿刚度的影响,余弦齿轮的轮齿刚度随着齿数、模数和压力角的增加而增大,但当齿数比较大时,轮齿刚度基本不变。The stiffness of cosine gears was calculated by using finite element methods （FEM）, and the results were compared with those of involute gears. The influences of design parameters including the number of teeth, the modulus and the pressure angle on the stiffness were studied. The results show that the stiffness of cosine gears is better than that of involute gears, and it increases with the growth of the pressure angle, the modulus and the number of teeth, but it is nearly not change when the number of teeth is large enough.
