The invention discloses a crane wheel device which comprises a wheel, a wheel shaft, a first disc bearing and a second disc bearing, the first disc bearing and the second disc bearing are sequentially installed in an inner hole of the wheel from a shaft shoulder of the wheel shaft in the axial direction of the wheel shaft, and the inner circumferential face of the inner hole of the wheel serves as a bearing outer ring; a spacer ring is arranged on the portion, located in an inner hole of the wheel, of the wheel axle in a sleeving mode and located between a bearing inner ring of the first disc bearing and a bearing inner ring of the second disc bearing. Bearing check rings are fixed to the positions, corresponding to the first disc bearing and the second disc bearing, of the two sides of the wheel. The two side ends, extending out of the inner hole of the wheel, of the wheel shaft are sleeved with shaft end baffle structures. According to the crane wheel device, the overall width and size are reduced, and the diameter of the wheel is reduced under the same wheel bearing pressure, so that the crane wheel device is particularly suitable for small and medium-sized cranes.

    本发明公开了一种起重机车轮装置,包括车轮、车轮轴、第一盘轴承、第二盘轴承,其中,所述第一盘轴承和所述第二盘轴承从所述车轮轴的轴肩开始沿车轮轴轴向顺次安装在所述车轮的内孔中,以车轮内孔的内周面作为轴承外圈;所述车轮轴的位于车轮内孔中的部分上套置有隔环,所述隔环位于所述第一盘轴承的轴承内圈和所述第二盘轴承的轴承内圈之间;所述车轮的两侧在对应于所述第一盘轴承和所述第二盘轴承的位置固定有轴承挡圈;在所述车轮轴的伸出车轮内孔的两个侧端套装有轴端挡板结构。本发明的起重机车轮装置减小了整体宽度和体积,并且在相同车轮承压下车轮直径得以减小,从而特别适用于中小型起重机。
