The invention discloses a wheel assembly, a universal wheel structure and a robot, and relates to the technical field of robots. The wheel assembly comprises a wheel body and an oil-containing shaft sleeve. A shaft hole is formed in the wheel body and comprises a first hole section, a second hole section and a third hole section which are arranged in the first direction, and the hole diameter of the second hole section is smaller than that of the first hole section and that of the third hole section. The oil-containing shaft sleeve penetrates through the shaft hole and is integrally formed through the powder metallurgy technology, an annular groove is defined in the outer wall of the oil-containing shaft sleeve in the circumferential direction of the oil-containing shaft sleeve, and the hole wall of the second hole section is clamped in the annular groove. According to the wheel assembly, vibration and noise are absorbed through the oil-containing shaft sleeve, the friction coefficient between the wheel body and the wheel shaft is reduced, and the situation of abnormal sound caused by movement abrasion of the wheel body is prevented.

    本申请公开了一种轮子组件、万向轮结构及机器人,涉及机器人技术领域。轮子组件包括轮体和含油轴套。轮体开设有轴孔,轴孔包括沿第一方向设置的第一孔段、第二孔段和第三孔段,第二孔段的孔径均小于第一孔段和第三孔段的孔径。含油轴套穿设于轴孔,且含油轴套由粉末冶金工艺一体成型制成,含油轴套的外壁沿其周向限定出环形凹槽,第二孔段的孔壁卡接于环形凹槽内。本申请提供的轮子组件,通过含油轴套吸收振动和噪音,降低轮体与轮子轴之间的摩擦系数,防止轮体运动磨损导致异响的情况发生。
