Inner curve radial plunger type rotary motor for rotary mechanism

The utility model relates to an inner curve radial plunger type rotary motor for a rotary mechanism. The inner curve radial plunger type rotary motor comprises an output shaft, a front shell, a rotary assembly, a track assembly, an oil distribution assembly, a rear shell, a brake shaft, a brake assembly and a double-channel oil seal structure. After the inner curve radial plunger type rotary motor for the rotary mechanism is connected into a hydraulic system, the brake assembly brakes and releases the rotary motor through the action of releasing hydraulic oil, hydraulic oil of a hydraulic loop acts on the rotary assembly through a high-pressure oil port and a low-pressure oil port in the rear shell and the oil distribution assembly to enable the rotary assembly to rotate, and the output shaft is output through spline connection. The inner curve radial plunger type motor is directly driven, use of a planetary gear speed reducing mechanism is avoided, gear transmission defects are reduced, transmission precisio
