一引言在现代工业中机器的速度不断提高,而最常用的滚动轴承随着转速的提高,动应力迅速增大,虽然采用高级的轴承材料及高的加工精度,轴承的使用寿命仍很短,一般只有30～40小时。滑动轴承因没有滚动体,而代以润滑层,可避免高速旋转时所产生的离心力,此时限制转速的提高是润滑油高的粘度,在高速旋蒋下摩擦力矩大大地增加,产生很多的热量,破壤轴承的正常工作。
I. INTRODUCTION In the modern industry, the speed of the machine continues to increase, and the most commonly used rolling bearing with the speed increase, dynamic stress rapidly increased, although the use of advanced bearing materials and high machining accuracy, the bearing life is still very short, general Only 30 to 40 hours. Sliding bearing because there is no rolling body, and replaced by the lubricating layer, to avoid the centrifugal force generated when the high-speed rotation, this time to limit the increase in speed is the high viscosity of lubricating oil, spin at high speed Jiang greatly increase the friction torque, resulting in a lot of Heat, broken soil bearing the normal work.
