The invention discloses a thrust wheel axle, a thrust wheel and a crawler crane. The thrust wheel axle comprises an axle body, a first oil outlet, a second oil outlet and a lubricating oil channel, the first oil outlet and the second oil outlet are formed in the two ends of the axle surface of the axle body, and the lubricating oil channel is arranged in the axial direction of the axle body and penetrates through the axle body; and the first oil outlet is communicated with the second oil outlet through the lubricating oil channel. The first oil outlet and the second oil outlet are formed in the axle body, two-way oil outlet can be achieved, meanwhile, the lubricating oil channel penetrates through the axle body, two-way oil injection can be achieved, and lubricating operation on the axle body is more convenient.
本发明公开了一种支重轮轴、支重轮和履带起重机,包括轮轴本体、第一出油口、第二出油口和润滑油道,所述第一出油口和第二出油口设于轮轴本体的轴面的两端,所述润滑油道沿轮轴本体的轴向布设,并贯穿轮轴本体,所述第一出油口通过润滑油道与第二出油口贯通。本发明通过在轮轴本体上设置第一出油口、第二出油口,能够实现双向出油,同时通过将润滑油道贯穿轮轴本体,能够实现双向注油,使得对轮轴本体的润滑操作更方便。
