The invention relates to the technical field of engineering machinery, in particular to a walking device and engineering machinery. The walking device comprises a crawler belt, a trolley frame and thrust wheels, and the trolley frame is arranged in the crawler belt; the track roller is arranged in the track and located at the bottom of the trolley frame, the track roller comprises a roller body, a roller shaft and an end cover, the roller shaft penetrates through the roller body, a first sealing structure is arranged between the roller shaft and the roller body, the end cover comprises a first main body and a second main body, and the first main body and the second main body are both in interference connection with the roller shaft. The first body and the second body are arranged at intervals in the axial direction of the axle, and the first body is arranged between the first sealing structure and the second body. The temperature of the first main body is reduced compared with the second main body, the temperature of the wheel shaft and the wheel body transmitted by the first main body is attenuated again, in addition, the first sealing structure is arranged between the wheel shaft and the wheel body, so that the actual temperature of the first sealing structure is smaller compared with the external temperature, and the influence of high temperature on the first sealing structure is reduced.
本发明涉及工程机械技术领域,尤其涉及一种行走装置及工程机械。行走装置包括履带、台车架和支重轮,台车架设置于履带内;支重轮设置于履带内,支重轮位于台车架的底部,支重轮包括轮体、轮轴和端盖,轮轴穿设于轮体,轮轴与轮体之间设置有第一密封结构,端盖包括第一主体和第二主体,第一主体与第二主体均与轮轴过盈连接,且第一主体与第二主体沿轮轴的轴向方向间隔设置,第一主体设置于第一密封结构与第二主体之间。第一主体的温度会相较于第二主体而降低,第一主体传递个轮轴和轮体的温度会再次衰减,此外第一密封结构设置于轮轴与轮体之间,这样第一密封结构的实际温度相较于外界温度而言较小,减少高温对第一密封结构的影响。
