摘要

本文介绍了X65Cr14合金钢球轴承和氧化锆陶瓷轴承在液氮降至-195℃下的内摩擦研究结果。由制造商添加的标准润滑脂，而石墨和二硫化钼粉末在测量期间用于润滑轴承。还进行了试验，以检查无润滑轴承的运行性能。测量了轴承内摩擦随温度变化的功率。二硫化钼的轴承内摩擦最小，其有效的润滑性能对两种类型的滚珠轴承进行了验证。石墨粉几乎同样有效，其优点是适合用于与食品接触的机器。

Internal Friction of Ball Bearings at Very Low Temperatures

Results of the study on the internal friction of steel ball bearings made of X65Cr14 alloy and ceramic bearings made of zirconium oxide operating at temperatures lowered by liquid nitrogen down to –195 °C are presented in this paper. Standard grease added by the manufacturer, while graphite and molybdenum disulphide powder were used for lubrication of the bearings during the measurements. Tests were also carried out to examine the performance of the bearings operating without lubrication. The power of bearing internal friction versus temperature was measured. The lowest bearing internal friction was observed for molybdenum disulphide, whose effective lubricating performance was verified for both types of ball bearings. Graphite powder was almost equally effective with the advantage of being suitable for use in machines that come into contact with food.
