采煤机在井下使用过程中需要定期维护保养,齿轨轮轴承则需要每周进行注油保养。为提高采煤机行走机构在复杂地质条件下工作的可靠性,研究了免维护轴承在采煤机齿轨轮组中的应用,免维护轴承的齿轨轮组,其结构简单,设计合理,可与原齿轨轮组完全互换,使用操作便捷,尤其是在井下工作面有限的空间里,使工人免于反复对轴承注油保养,降低了工人劳动强度,同时又能保证其使用寿命和过煤量,减少了采煤机的生产成本,提高了工作效率。
Shearer needs regular maintenance during downhole use and gear wheel bearings require weekly oiling and maintenance. In order to improve the reliability of shearer working under complex geological conditions, the paper studied the application of maintenance-free bearings in the shearer gear set and the wheel set of maintenance-free bearings. The structure is simple, the design is reasonable, It can be completely interchangeable with the original rack and wheel set and is easy to use and operate. Especially in the limited space of the underground working face, workers are prevented from repeatedly lubricating the bearings, reducing the labor intensity of workers and at the same time guaranteeing their service life and Over the coal, reducing the production costs of shearer, improve work efficiency.
