The invention relates to the technical field of engineering machinery, and provides a crawler wheel, a crawler walking device and an operation machine.The crawler wheel comprises a wheel shaft; the axis of the wheel body is parallel to the axis of the wheel shaft, the wheel shaft penetrates through the wheel body, the wheel body is in clearance fit with the wheel shaft, a first through hole with the controllable on-off state is formed in the wheel body, one end of the first through hole penetrates through the outer surface of the wheel body, and the other end of the first through hole communicates with a gap between the wheel body and the wheel shaft; the end covers are fixedly connected to the two ends of the wheel shaft respectively and make sealing contact with the ends of the wheel body, second through holes with the controllable on-off state are formed in the end covers, one ends of the second through holes penetrate through the outer surfaces of the end covers, and the other ends of the second through holes are communicated with the gap between the wheel body and the wheel shaft. Through the arrangement, the problem of oil leakage caused by increase of metal powder in the crawler wheel in the prior art is solved.
本发明涉及工程机械技术领域,提供一种履带轮、履带行走装置及作业机械,其中,履带轮包括轮轴;轮体,轴线与轮轴的轴线平行,轮轴贯穿轮体,且轮体与轮轴间隙配合,轮体上设置有通断状态可控的第一通孔,第一通孔的一端贯穿轮体的外表面,另一端连通于轮体与轮轴之间的间隙;一对端盖,分别固定连接于轮轴的两端,且与轮体的端部密封接触,端盖上设置有通断状态可控的第二通孔,第二通孔的一端贯穿端盖的外表面,另一端连通于轮体与轮轴之间的间隙。如此设置,解决了现有技术中的履带轮因其内部金属粉末的增加导致的漏油的问题。
