通过低温条件下的热导试验得出：传热温差对热导测定影响较小，轴承载荷一定时，轴承的热导随载荷增大而变大，在液氮温度到200K的温度范围内．不锈钢球轴承的热导主要取决于球的热导。给出了静态热导与轴承载荷和温度的关系。附图6幅，参考文献6篇。
The result of the thermal conductivity test at low temperature shows that the heat transfer temperature difference has little effect on the thermal conductivity measurement. When the bearing load is constant, the thermal conductivity of the bearing becomes larger with the increase of the load, which is within the temperature range of liquid nitrogen to 200K. The thermal conductivity of stainless steel ball bearings depends mainly on the ball’s thermal conductivity. The relationship between static thermal conductivity and bearing load and temperature is given. Figure 6, reference 6 articles.
