摘要
齿轮的温度主要受到滑动摩擦、润滑油冷却以及环境温度的影响。齿轮在传动过程中如果环境温度、转速、转矩发生了变化,齿轮的温度也会有明显的变化。当齿轮温度升高时,会造成润滑油膜的破裂,使齿面磨损加剧,引起胶合;过高的温度还会使齿轮产生热变形,造成齿轮承载能力的下降。利用有限元分析软件ANSYS建立变位斜齿圆柱齿轮的有限元模型,并对模型加载、求解,最后通过对温度场云图的分析找出齿轮温度随着环境温度、转速、转矩的变化而变化的规律。
The temperature of gear is mainly affected by sliding friction,oil cooling and ambient temperature.If the ambient temperature,rotational speed and torque changed,the temperature of gear will also be changed obviously.The finite element modal of modefied helical gear is established by finite element software ANSYS.Through loading,solving the modal and analyzing the temperature field cloud picture,the regulation of how gear temperature changes with the change of ambient temperature,rotational speed and torque is obtained.
