Abstract

Tapered roller bearings are often used to support pinions in gear units of electric trains. On the other hand, recently, the application of cylindrical roller bearings with ribs has also been proposed, in which the internal clearance changes little depending on the operating conditions. This study aims to elucidate the effect of differences in just these two types of pinion bearings on the performance of gear units and thereby verify the applicability of cylindrical roller bearings with ribs to railway gear units. Tapered roller bearings and cylindrical roller bearings with ribs of the same dimensions were subjected to rotational tests in the same gear unit. The results showed that the effects of the atmospheric temperature on the maximum temperature, the maximum rate of temperature rise, and the torque of the bearings were not significantly different between the tapered roller bearings and the cylindrical roller bearings with ribs. As the atmospheric temperature decreases, the maximum temperature decreases, and the maximum rate of temperature rise and the torque increase. On the other hand, the endplay values had a significant effect on these values in the tapered roller bearings, while they had little effect on the cylindrical roller bearings with ribs.

齿轮装置小齿轮用圆锥滚子轴承和圆柱滚子轴承在旋转试验中的性能比较

圆锥滚子轴承通常用于支撑电气列车齿轮单元中的小齿轮。另一方面，最近也有人提出应用带肋的圆柱滚子轴承，这种轴承的内部游隙随工作条件变化很小。本研究旨在阐明这两种小齿轮轴承的差异对齿轮装置性能的影响，从而验证带肋圆柱滚子轴承在铁路齿轮装置中的适用性。相同尺寸的圆锥滚子轴承和带挡边圆柱滚子轴承在同一齿轮装置中进行了旋转测试。结果表明，大气温度对轴承的最高温度、最大温升速率和扭矩的影响在圆锥滚子轴承和带挡边圆柱滚子轴承之间没有显著差异。随着大气温度的降低，最高温度降低，最大温升速率和扭矩增加。另一方面，端隙值对圆锥滚子轴承的上述值有显著影响，而对带挡边的圆柱滚子轴承影响不大。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
