The invention belongs to the field of crane wheels, and particularly relates to a rim self-lubricating combined type heavy crane wheel which comprises a wheel working sleeve, a wheel inner ring, a lubricating assembly, a first tensioning assembly and a second tensioning assembly. The inner ring of the wheel inner ring is in interference fit connection with a wheel shaft of the crane through a first tensioning assembly; the outer ring of the wheel inner ring and the inner ring of the wheel working sleeve are in interference fit connection through a second tensioning assembly; a lubricating assembly is installed on the outer ring of the wheel working sleeve and used for achieving lubrication. Compared with the prior art, the service performance of the wheel tread working layer can be improved, the wheel working layer can be independently, rapidly and efficiently replaced, assembled and disassembled on the premise that an axle is not disassembled, and the impact load before the wheel flange makes contact with the side face of a track and the friction generated when the wheel flange makes contact with the side face of the track are reduced.

    本发明属于起重机车轮领域,特别是一种轮缘自润滑组合式重型起重机车轮,包括车轮工作套、车轮内圈、润滑组件、第一涨紧组件和第二涨紧组件;车轮内圈的内圈与起重机的车轮轴通过第一涨紧组件实现过盈配合连接;车轮内圈的外圈与车轮工作套的内圈之间通过第二涨紧组件实现过盈配合连接;车轮工作套的外圈上安装有润滑组件,用于实现润滑。与现有技术性相比,本发明可以实现改善和提高车轮踏面工作层使用性能,在不拆卸车轴的前提下实现车轮工作层的单独快速、高效更换与装拆,减少轮缘与轨道侧面接触前冲击载荷和轮缘与轨道侧面接触时的摩擦。
