Low-friction efficient cycloid hydraulic motor

The invention relates to the technical field of hydraulic transmission system execution elements, in particular to a low-friction efficient cycloid hydraulic motor which comprises a front cover, an output shaft, a body shell, a rotor, a stator and a rear cover. The low-friction efficient cycloid hydraulic motor is composed of a front cover, an output shaft, a body shell, a rotor, a stator and a rear cover, a linkage shaft is arranged between the output shaft and the rotor, combined lateral driving tooth heads are arranged at the two ends of the linkage shaft, and an internal adjusting locking mechanism used for controlling the combined lateral driving tooth heads is arranged in the linkage shaft. The device can be adjusted and locked, and is convenient to disassemble; the arc-shaped limiting transmission grooves matched with the combined type lateral driving tooth heads are formed in the inner side faces of the inner transmission tooth holes and the inner transmission tooth grooves, the rotor and the output s
