摘要
鉴于润滑油对机床主轴系统温升影响较大,现分别采用2种不同润滑油给轴承润滑,分析主轴在不同转速下温度和热应变变化情况,利用Workbench有限元分析软件对高速轧辊磨床主轴进行热-结构耦合分析,得出主轴在不同转速下的温度场分布云图和热应变云图,为进一步研究机床的热误差提供了理论依据。
In view of lubricating oil has great influence on the temperature rise of the machine tool spindle system. Separately using two different lube oil lubricates bearing. The spindle is analysed by the change of the temperature and thermal strain which it is under different rotational speed. The Workbench finite element analysis software is used to analyse the heat-structure coupling from the high speed roll grinder spindle. It is concluded that the spindle under different rotational speed of map of tire temperature field and thermal strain contours, and it also provides an important theoretical support for the thermal error of machine tool.
