Abstract Based on the structural features of a double-row tapered roller bearing (DTRB), a test rig for multipoint temperature measurement was built to investigate the temperature filed characteristics of DTRB under different operating conditions. Firstly, the composition of the test rig and the measuring instruments are described and the loading method is introduced. Secondly, a multipoint temperature measurement method for inner and outer rings of DTRBs is introduced, including the arrangement of the sensors and the signal transmission. Finally, the influence of rotational speed and external load on the circumferential, axial, and radial temperature rise and temperature distribution in a DTRB is studied. Results show that for the stationary bearing outer ring, the temperature rise in the load zone is significantly higher than that in the non-load zone. Under combined load, there are obvious temperature differences in the axial, circumferential, and radial directions of a DTRB.

双列圆锥滚子轴承温度场的试验研究

摘要 基于双列圆锥滚子轴承（DTRB）的结构特点，搭建了多点测温试验台，研究了双列圆锥滚子轴承在不同工况下的温度场特性。首先介绍了试验台和测量仪器的组成，并介绍了加载方法。其次，介绍了DTRB内外环多点测温方法，包括传感器的布置和信号的传输。最后，研究了转速和外载荷对 DTRB 的周向、轴向和径向温升和温度分布的影响。结果表明，对于静止轴承外圈，负荷区的温升明显高于非负荷区。在复合载荷下，DTRB的轴向、周向和径向都有明显的温差。
