The embodiment of the invention provides a carrier wheel structure of an excavator and the excavator, and relates to the field of excavators. The problem that the using performance of an existing carrier wheel is insufficient is solved. The carrier wheel structure comprises a wheel shaft, a wheel body and a bearing assembly. Two ends of the wheel shaft are mounted on a crawler frame of the excavator; the bearing assembly sleeves the wheel shaft, and the wheel body sleeves the bearing assembly, so that the wheel body can rotate relative to the wheel shaft. The excavator comprises the excavatorcarrier wheel structure. The bearing assembly is sleeved between the wheel body and the wheel shaft, so that the friction resistance is reduced, the wheel body rotates more flexibly relative to the wheel shaft, the friction between the carrier roller and the crawler belt is reduced, and the service life of the carrier roller is prolonged; meanwhile, the two ends of the wheel shaft are installed onthe crawler frame, the two ends of the carrier wheel are supported on the crawler frame, the stress condition of the carrier wheel can be improved when the excavator turns, performance is improved, and therefore the service life of the carrier wheel is further prolonged.

    本发明的实施例提供了一种挖掘机托链轮结构及挖掘机,涉及挖掘机领域。旨在改善现有的拖链轮使用性能存在不足的问题。挖掘机托链轮结构包括轮轴、轮体和轴承组件;轮轴的两端用于安装在挖掘机的履带架上;轴承组件套装在轮轴的外周,轮体套装在轴承组件的外周,使得轮体可相对于轮轴转动。挖掘机包括挖掘机托链轮结构。在轮体和轮轴之间套装轴承组件,减小摩擦阻力,使得轮体相对轮轴转动更加灵活,进而减小托链轮与履带之间的摩擦,延长托链轮的使用寿命;同时轮轴的两端安装在履带架上,托链轮的两端都支撑在履带架上,在挖掘机转弯时能够改善托链轮的受力情况,性能提升,从而进一步延长托链轮的寿命。
