本文实验研究了可倾瓦推力轴承在运行过程中的不同载荷下、不同升速时间下从起始转速 80 0r/min升到截止转速 5 0 0 0r/min时油膜温度和油膜厚度变化值的瞬态变化规律。实验时 ,在瓦块进油、出油边及油膜与瓦块接触面上布置了若干根铜 -康铜热电偶和电涡流传感器。实验表明 :在运行过程中 ,转速升高时 ,不同的升速时间对油膜温度、进油边温度、出油边温度以及油膜厚度变化值的影响基本相同 ;不同载荷对油膜温度、进油边温度以及出油边温度的影响基本相同 ,但不同载荷对油膜厚度变化值的影响却不一样 ,载荷越大 ,油膜厚度变化值就越大 ;载荷越小 ,油膜厚度变化值就越小。
In this paper, the changes of the oil film temperature and the oil film thickness under different loads during the operation of the tilting pad thrust bearing are investigated experimentally from the initial rotation speed of 80 0r / min to the cutoff rotation speed of 500r / min at different speedup times Transient variation. Experiments, the pad into the oil, the oil side and the oil film and pad contact surface layout of a number of copper - Constantan thermocouple and eddy current sensor. Experiments show that: during operation, when the speed is increased, the effect of different speedup time on the temperature of oil film, the temperature of oil entering edge, the temperature of oil out edge and the change of oil film thickness are basically the same; when different loadings affect the oil film temperature, The effects of temperature and outburst temperature are basically the same, but different loads have different effects on the change of oil film thickness. The larger the load, the greater the change of oil film thickness; the smaller the load, the smaller the change of oil film thickness.
