Abstract

The invention discloses axial series ultra whole-revolution swing hydraulic motors, which comprise a primary stator, a primary stator blade, a primary rotor blade, a secondary stator, a secondary stator blade, a secondary rotor blade, a rotating shaft and a cover board. The secondary stator, the secondary stator blade, the secondary rotor blade, the rotating shaft and the cover board form a secondary swing motor. The primary stator, the primary stator blade, the primary rotor blade and the secondary swing motor form a primary swing motor. The primary and secondary two swing motors in the invention are axially arranged. The axial series ultra whole-revolution swing hydraulic motor has simple and compact structure and is favorable for reduction of a rotary inertia. Hydraulic circuits are connected in series. The oil distribution is simple. The superposition of rotating angles of the rotating shaft is realized, the problem that the rotating angle of the conventional swing hydraulic motor is limited to the range of less than 360 degrees is solved. And the motors are suitable for a direct drive hydraulic servo power mechanism requiring the rotating angle more than one revolution and less than two revolutions.

Description

technical field [0001] The invention relates to an axial tandem super full-circle swing hydraulic motor, which belongs to hydraulic servo drive technology. Background technique [0002] Hydraulic drive has the advantages of high power-to-weight ratio and large force (moment)-to-mass (inertia) ratio, and is suitable for high-power and strong (torque) drives. Hydraulic servo control enables high response, wide speed regulation and low steady rate performance. Therefore, hydraulic drive and its servo control technology are widely used in aerospace, marine vehicles, construction machinery and other fields. [0003] Although conventional plunger motors, vane motors, and gear motors can achieve continuous rotation, they are not suitable for servo drives due to their complex structures, large moment of inertia, and the existence of rotational speed and torque pulsations. Swing hydraulic motors are usually used in hydraulic servo drive applications for rotary motion, such as in ap...
