    摘要:

    在实际工况中,轴承各个组成部件间以及润滑剂的相互摩擦发热,导致轴承系统温度过高,严重降低了轴承的精度和寿命。针对该问题,选取轴承外圈这一特定轴承组件为分析对象,建立轴承温升模型,结合workbench软件仿真和实验,探索轴承在不同工况下,轴承外圈的温度场分布情况。在workbench的热稳态分析中,轴承外圈的温度分布不是一维的,而是与径向尺寸、周向角度相关的二维温度场。在实验中,改变轴承的转速和径向载荷力,当轴承系统温度稳定时,通过测试系统获取了轴承外圈温度数据,结果表明:外圈温度沿周向角度上有差异,靠近载荷区的温度略高,温差最大达到了1.6℃。最后仿真数据和实验数据误差控制在5%以内。

    Abstract:

    Under actual working conditions, heat is mainly generated by the friction among the various components of the bearing ,and lubricant can also generate some.That heat causes bearing system temperature high, severely reducing the accuracy and life of the bearing system. To solve this problem, firstly a resonable model about heat spread in the system was bulit , then bearing outer ring was selected for the analysis. For the example of deep groove ball bearing outer ring , some results about temperature distribution of the bearing outer ring were gotten when the speed and radial load force were changed. In the software Woekbech solution, the bearing outer ring temperature distribution was not a one-dimensional field,but radial dimension and circumferential angle were involved. In the experiment, as the speed and radial load bearing force change, the bearing outer ring temperature data was acquried.when the bearing system temperature was stable , a temperature difference arosed along the circumferential direction, the temperature near the loading zone was slightly higher, the maximum temperature difference reached 1.6 ℃. Finally, simulation and experimental data error was controled in less than 5%.
