High-rotating-speed and high-power hydraulic motor

The utility model belongs to the technical field of hydraulic motors, and particularly relates to a high-rotating-speed and high-power hydraulic motor which comprises a shell, and a plunger is arranged in the shell. The plunger is directly arranged on the shell, so that the structure of the motor is more compact, the diameter of the plunger is increased, the effect of improving the displacement of the motor is achieved, the eccentric value of the crankshaft is ensured, the distance between the mass center of the crankshaft and the rotation center of the crankshaft is reduced, rotational inertia is reduced, and the service life of the motor is prolonged. The window surface of the connecting rod body is changed into an oilless bearing structure, and the oilless bearing adopts a structure that a metal sheet is attached to a nonmetal layer, so that the connecting rod body can bear higher relative sliding speed in the process of pushing a crankshaft to rotate, the working rotating speed and the output power of the
