The purpose of this paper is to introduce a high-speed rolling bearing test rig supported by sliding bearing and its first experimental results.,Through analyzing the disadvantages of using rolling bearing as supporting bearing, the bottlenecks that need to be resolved urgently in the development of rolling bearing experimental technology, and the advantages of the sliding bearing, this study used the sliding bearing as the supporting bearing for the high-speed rolling bearing test rig for the purpose of prolonging the service life, increasing the load capacity and promoting the operating stability.,The experimental results show that the high-speed rolling bearing test rig supported by sliding bearing could stably rotate at 70,800 rpm without installing the test bearing; the temperature of the sliding bearing is increasing with the rotating speed and the maximum is less than 95°C. Moreover, the new test rig, installing an angular contact ball bearing as test bearing, could also stably rotate at 54,000 rpm with 2 kN axial load and 1 kN radial load; the temperature of the sliding bearing is increasing with the rotating speed and the maximum temperature is less than 97°C.,Rolling test rig has been established.,This paper proposes a high-speed rolling bearing test rig supported by sliding bearing, which greatly prolongs the service life, increases the load capacity and promotes the operating stability, moreover, reduces the risk of supporting bearing failure before the test bearing. This paper can also provide a new idea and reference for the design of similar bearing test rig.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-03-2020-0085/

滑动轴承支撑的高速滚动轴承试验台

滑动轴承温度随转速升高而升高，最高不超过95℃。此外，新试验台安装角接触球轴承作为试验轴承，在2kN轴向载荷和1kN径向载荷下也能以54,000rpm的速度稳定旋转；滑动轴承的温度随着转速的升高而升高，最高温度小于97℃。,建立了滚动试验台。,本文提出了一种滑动轴承支撑的高速滚动轴承试验台，极大地提高了滚动轴承的温度。延长使用寿命，增加承载能力，促进运行稳定性，同时降低了试验轴承前支撑轴承失效的风险。本文也可为类似轴承试验台的设计提供新的思路和参考。
