某掘进机主轴轴承系统方案的仿真分析

Simulation Analysis of a Tunnelheader Spindle Bearing System

根据滚动轴承设计理论和接触力学理论,针对某掘进装备主轴轴承存在工作可靠性问题,应用Romax Designer软件对掘进机主轴轴承系统进行仿真分析,详细分析了不同方案在实际工况载荷作用下轴的弯曲变形、应力以及滚动轴承的载荷分布和应力分布,计算出了受力最大轴承滚动体所受的最大力与最大接触应力;通过对比确定了最佳主轴轴承系统方案,为该型号掘进机主轴轴承系统的设计与制造提供了的参考.

According to the rolling bearing design and contact mechanics theories,the engineering analysis software Romax Designer is applied to simulate and analyze the main shaft bearing system of the tunneling machine,and the bending deformation and stress of the shaft under the actual working load of different schemes are analyzed in detail.Aiming at the problem of working reliability of the main shaft bearing of a tunneling equipment,as well as the load distribution and stress distribution of the rolling bearing,the maximum force and the maximum contact stress of the rolling element are calculated.Through comparison,the best scheme of the main shaft bearing system is determined,which provides a reference for the design and manufacture of the main shaft bearing system of this type of tunnel header.
