A shell rotating type curve hydraulic motor consists of a stator, a centering roller bearings, a low pressure seal ring, a large end cover, an oil distribution shaft, an oil distribution sleeve, a beam rolling wheel pair, a rotor, a piston, a single row radial ball bearing, a guide rail, a cross joint, a small end cover, an O shape seal ring, a poking fork, a micro-adjusting screw. The torque is output by the shell. The oil distribution shaft is provided with two oil circuits. The oil distribution sleeve is provided with two groups of window which are mutually arranged. The oil distribution sleeve and the oil distribution shaft are fit with an interference fit. The two oil circuits of the oil distribution shaft are respectively connected with the two groups of window of the oil distribution sleeve. The window on the oil distribution sleeve is connected with the stator piston cylinder hole. the characteristics are that the torque is output by the shell, the oil distribution shaft can float freely, the running speed is slow, starting torque is big, output torque is big, stepless speed regulation is realized, low speed stability performance is good, the structure is compact, and the using life is long. The hydraulic motor can be applied in the mechanism where slow speed rotating is required, such as mining, metallurgy, ship, etc.
