The invention relates to a walking device, and particularly relates to a walking wheel assembly which comprises a walking wheel, transparent covers, spline shafts, sealing rings and bearings. The transparent covers are symmetrically arranged on the left side and the right side of the walking wheel, one end of the transparent cover on each side is connected with a rack plate, the bearings are embedded in the other ends of the transparent covers, and the transparent covers are rotatably connected with a center shaft of the walking wheel through the bearings; one end of each spline shaft penetrates into the central shaft and is in key connection with the central shaft, the other end of the spline shaft is connected with the motor speed reducer, and a torque is provided by the motor speed reducer; and a protruding shaft shoulder is arranged between the rim on each side of the walking wheel and the center shaft, sealing rings are arranged between the protruding shaft shoulder and the other end of the transparent cover and at the position, located on the outer surface of the inner ring of the bearing, in the transparent cover, a closed cavity is formed between the two sealing rings, and lubricating grease for providing lubrication for the bearing is stored in the closed cavity. The assembly is light in weight, compact in structure and capable of saving energy; the middle closed oil cavity can prolong the bearing lubrication period and prolong the service life of the bearing; and maintenance is convenient, and manufacturing cost is reduced.

    本发明涉及行走装置,具体地说是一种行走轮组件,包括行走轮、透盖、花键轴、密封圈及轴承,行走轮的左右两侧对称设有透盖,每侧透盖的一端与机架板相连,另一端内部镶嵌有轴承,透盖通过轴承与行走轮的中心轴转动连接;花键轴的一端穿入中心轴内,并与中心轴键连接,花键轴的另一端与电机减速机相连,由电机减速机提供转矩;行走轮每侧的轮缘与中心轴之间均设有凸起轴肩,凸起轴肩与透盖的另一端之间以及透盖内部位于轴承内圈外表面处均设有密封圈,两处密封圈之间形成封闭腔室,封闭腔室内存储有为轴承提供润滑的润滑脂。本发明重量轻、结构紧凑,能够节约能源;中部封闭油腔能够延长轴承润滑周期,提高轴承使用寿命;方便维护,降低制造成本。
