摘　　要：文章中建立了斜齿轮齿面温度有限元分析模型,模型考虑了齿面与空气和润滑油的对流换热,以及齿轮副摩擦产生的热流量.通过与实验测试得到的齿面温度对比来验证该模型.最后,利用该有限元模型分析了典型的齿轮设计参数对齿面温度的影响.结果表明,本文建立的有限元分析模型得到的温度和实验测试结果基本一致,最大误差在5.67%以内;并且,齿面温度随着齿顶高系数和齿宽的增加而增加,并随着螺旋角的增加而上下波动.本文提出的模型为高速斜齿轮抗胶合设计提供了依据.In this study, finite element （FE）model of helical gear was developed to evaluate their surface temperature. In this model, heat convection between gear tooth and air as well as lubricant was considered, and heat was generated due to gear friction. The model was validated by comparing to the measured temperature of helical gears in an existing experiment. Finally, the effect of gear design parameters on helical gear temperature was determined by the current FE model. It was shown that the predicted temperature by the current FE model is consistent with the measured temperature in experiment, and the maximum error is within 5.67%. Moreover, gear temperature was increased by increasing addendum coefficient and face width. However, gear temperature was fluctuated with the change of helix angle. This work provides aguidance for the design of high-speed helical gears.
