A lubricating structure for a gauge-changeable wheelset and a gauge-changeable wheelset. The lubricating structure comprises wheels (1), an axle (2), and sliding mechanisms. The wheels are slidably disposed at both ends of the axle, the sliding mechanisms are respectively connected to the outer sides of the wheels, and are located in the axle boxes at both ends of the axle, and the wheels are unlocked and locked by the sliding mechanisms. A sealing structure (6) is provided between the inner side of each wheel and the axle, a first cavity (7) is formed among the inner side of the wheel, the axle, and the sealing structure, a second cavity (8) is formed between the outer side of the wheel and the sliding mechanism, and a third cavity (9) is formed between the sliding mechanism and the axle box. The wheel is provided with first oil injection holes (10) leading to the joint between the wheel and the axle, and the axle box is provided with second oil injection holes (11) leading to the sliding mechanism. The lubricating structure can increase the lubrication of a friction surface, reduce the wear of key parts easy to wear, and prolong the overall life of the gauge-changeable wheelset.

    Disclosed are a lubricating structure for gauge-changing wheelset and a gauge-changing wheelset. The lubricating structure for gauge-changing wheelset comprises: wheels (1), an axle (2), and sliding mechanisms; the wheels are slidably provided at both ends of the axle, and the sliding mechanisms are respectively connected to outer sides of the wheels and are located in axle-box bodies at both ends of the axle; and the wheels are unlocked and locked by the sliding mechanisms. A sealing structure (6) is provided between an inner side of the wheel and the axle, a first cavity (7) is formed between the inner side of the wheel, the axle and the sealing structure, a second cavity (8) is formed between the outer side of the wheel and the sliding mechanism, and a third cavity (9) is formed between the sliding mechanism and the axle-box body. The wheel is provided with first oil injection holes (10) leading to a connection between the wheel and the axle, and the axle-box body is provided with second oil injection holes (11) leading to the sliding mechanism. The lubricating structure of the present application may increase the lubrication of a friction surface, and reduce the wear of the key wear-prone parts, thereby extending the overall service life of the gauge-changing wheelset.
