摘要
为快速有效地预测主轴-轴承系统的稳态温度场,考虑径向热应力、离心应力及装配应力的影响,利用主轴-轴承径向热力耦合热网络模型,分析了轴系的发热特性。结果表明:主轴-轴承系统在轴承处温升明显,螺旋冷却管道对降低轴承外圈温升作用明显,随着转速的升高,轴承温升加剧,冷却效果也更加显著。
In order to predict steady temperature field of spindle-bearing system quickly and efficiently,the influence of radial thermal stress,centrifugal stress and assembly stress are considered,the spindle-bearing radial thermal mechanical coupling thermal network model is used to analyze heat characteristics of bearing system.The results show that the temperature rise of bearing is obvious in spindle-bearing system,and the spiral cooling pipe has an obvious effect to lower the temperature rise of bearing outer ring.The temperature of bearing rises severely and the cooling effect is more prominent with the increase of rotational speed.
