【摘要】 实验研究了可倾瓦推力轴承在 2 30 0～ 51 0 0r/min的名义转速范围内时 ,空载快速启动及慢速启动过程中推力轴承油膜温度和油膜厚度的瞬态变化规律 .实验表明 ,在启动过程中 ,油膜温度随转速的提高而升高 ,不同的升速时间对油膜温度的影响也不同 ,油膜的厚度也随转速的提高而升高 .更多还原

【Abstract】 The transient thermal effects are investigated for a tilting pad thrust bearing undergoing rapid and slow start up with rotation speed from 2 300 r/min to 5 100 r/min when load is absent. For start up, the oil temperature and variation of mean oil film thickness increase with rotational speed. Increase of rotational speed has a disparate effect on the oil temperature.更多还原
