基于材料力学方法,分析了轮齿刚度的变化规律。在此基础上,分析误差大小对轮齿刚度的影响。结果表明,随着误差的增大,其对轮齿刚度的影响也逐渐增加,且对齿根处刚度的影响远大于齿顶处。在相同误差情况下,对主动轮轮齿刚度的影响比对从动轮的影响大。

英文摘要：

Incorporating the error into the tooth stiffness model of spur gear, the variety law of gear stiffness was obtained based on material mechanics method, and the effects of the error on the gear stiffness were analyzed. The mechanical method was employed to compute the tooth stiffness instantaneously. The tooth stiffness was calculated as an effective function, which also include the effect of error by the difference of the y-axis. The method was illustrated via two error examples, and the effects of the error on the stiffness of different plots on the tooth were examined analytically. The results show that the effects of the error on the stiffness increases with the increase of error, the influences of the error on the dedendum stiffness is more evident than that on the addendum, and the influences on stiffness of the driving gear is greater than that of the driven gear under the same error.
