建立了铁磁性流体自密封润滑滑动轴承静动特性的计算模型,用差分法对轴承的油膜压力方程、温度方程以及轴瓦导热方程进行了联立求解,计算和分析了该模型轴承在不同偏心率和不同长径比等工况下的静动特性。结果表明,在小偏心率和小长径比条件下,采用该模型轴承是可行的,轴承油膜温度比有端泄轴承的相应值高,轴承转速是影响油膜温度的主要因素。设计更加有效合理的密封形式是这种轴承发展和广泛应用的关键
The calculation model of static and dynamic properties of ferrofluid self-sealing lubricated sliding bearing was established. The differential pressure method was used to solve the pressure equation of the oil film, the temperature equation and the heat conduction equation of the bearing. The influence of eccentricity And different long diameter ratio and other conditions under the static and dynamic characteristics. The results show that this model bearing is feasible under the conditions of small eccentricity and small aspect ratio. The bearing oil film temperature is higher than the corresponding value of end-leak bearing, and the bearing speed is the main factor affecting the oil film temperature. Design more effective and reasonable seal form is the key to the development and widespread application of this kind of bearing
