Hydraulic motor crankshaft connecting rod

In order to solve the problem, the crankshaft connecting rod of the hydraulic motor comprises a base body and a first through hole penetrating through the middle section of the base body, the base body comprises a connecting tail portion of an arc-shaped blocky structure, an opening in one end of the first through hole is located in the arc-shaped face of the connecting tail portion, and a wear-resisting sliding block is detachably connected to the connecting tail portion. The wear-resisting sliding block is of an arc-shaped blocky structure matched with the connecting tail structure, and a second through hole communicating with the first through hole is formed in the arc-shaped face of the wear-resisting sliding block. According to the utility model, hydraulic oil at the top of the plunger body of the hydraulic motor can normally flow into the binding surface of the connecting rod and the crankshaft to lubricate the crankshaft, and the problem that the connecting rod is abraded and scrapped can be fundamenta
