摘　　要：为研究轴速、前后唇角、接触宽度、抱轴力等参数对油封摩擦面上温度最大值的影响,文章利用FLU-ENT建立了唇形油封的二维轴对称模型,并进行计算。结果表明:随着轴速的增加,摩擦面上的温度最大值逐渐增加;前唇角的变化对摩擦面上的温度最大值影响较小,在轴速较低时几乎没有影响;后唇角的变化对摩擦面上的温度最大值几乎没有影响;随着接触宽度的增加,摩擦面上的温度最大值逐渐降低,且轴速越高,降低幅度越大;随着抱轴力的增加,摩擦面上的温度最大值逐渐增大,且增加的幅度随着抱轴力的增加而增加。轴速、接触宽度和抱轴力能显著改善摩擦面的温度。To research the influence of shaft speed, low-angle and high-angle, contact width and tackling force on the maximum temperature of friction area of seal, a two-dimensional axisymmetrical model of rotary lip seal was established and calculated by FLUENT. The results showed that the maximum temperature of friction area experienced a gradually increase with the rising of shaft speed. The influence of low-angle on the maximum temperature of friction area was not obvious, even little at lower speed. While the influence of high-angle on the maximum temperature was little at all tested speed. As the contact width increased, the maximum temperature of the friction area decreased, and the higher shaft speed, the greater the reduction rate. With the increase of axle force, the maximum temperature of the friction area increased, and the rising rate climbed with the axle force＇s increasing. Shaft speed, contact width and axle force can alter temperature of friction area effectively.
