本文叙述以液体摩擦润滑理论为基础,运用概率论和数理统计学的计算手段,根据轴瓦和轴颈配合的概率间隙,精确设计液体摩擦滑动轴承的方法及其优越性。一、液体擦摩滑动轴承概率间隙计算公式的推导滑动轴承是由轴瓦和轴颈两个零件配合而成的,如图1a所示。由于初始的系统性误差原因和随机性误差原因的影响,使轴瓦和轴颈的实际直径尺寸总偏离于公称直径尺寸。作为一批零件,它们的实际直径
Based on the theory of liquid friction lubrication, this paper describes the method and its superiority of the accurate design of the liquid friction sliding bearing based on the calculation of probability and mathematical statistics, according to the probability gap between bearing bush and journal. First, the liquid friction sliding bearing probabilistic formula for the calculation of clearance derived from the plain bearing and journal bearings with two parts, as shown in Figure 1a. Due to the initial systematic error and random error causes, the actual diameter of the bearing bush and journal deviation from the nominal diameter size. As a batch of parts, their actual diameter
