纵轴式掘进机截割部主轴承的选型分析

Choice of Main Bearing of Cutting Part for Longitudinal Roadheader

纵轴式掘进机截割头通过主轴与主轴承刚性连接,截割头的受力主要由主轴承承受。通过对截割头的受力分析,对所选择的截割部主轴承进行对比分析,选择更适合掘进机工况的主轴承。

The cutting head of the longitudinal roadheader and the main bearing is a rigid connection, so the main bearings of the cutting part is beared by the main bearing. Compare the performance of the main bearings of the cutting part with each other by analyzing the stress performance of the cutting head, and choose the most suited one for the working environment.
