Movable vane swing hydraulic oil cylinder

Abstract

A movable vane swing hydraulic oil cylinder comprises a rotor (1) and a stator (2). Rotor vane supports (8) distributed in the axial direction are arranged on the outer wall of the rotor (1), a rotor vane groove (5) is formed between every two rotor vane supports (8), rotor vanes (3) are arranged in the rotor vane grooves (5), stator vane supports (9) distributed in the axial direction are arranged on the inner circumference of the stator (2), a stator vane groove (6) is formed between every two stator vane supports (9), stator vanes (4) are arranged in the stator vane grooves (6), and the outer end faces, close to the inner side wall of the stator (2), of the rotor vanes (3) are matched with the inner side wall of the stator (2). The movable vane swing hydraulic oil cylinder is compact in structure, the stator vanes and the rotor vanes can be detached and replaced conveniently, sealing effects are good, torque is output stably, controllability is good, and the movable vane swing hydraulic oil cylinder can be widely applied to all kinds of metallurgical machines, petrochemical machines, aircraft wing steering engines, ship steering mechanisms and other fields.

Description

technical field [0001] The invention relates to a hydraulic swing cylinder, in particular to a movable vane swing hydraulic oil cylinder, which belongs to the technical field of hydraulic equipment. Background technique [0002] The vane-type swing hydraulic cylinder can convert hydraulic pressure into torque, and has the advantages of compact structure, high mechanical efficiency, stable torque output, good controllability, and is not easy to be invaded by external dust. The vane isolates the oil cylinder into a high-pressure chamber and a low-pressure chamber. Using the difference in hydraulic pressure acting on the blades from the high-pressure and low-pressure chambers, the rotor blades and rotors are driven to rotate and output torque; changing the direction of the hydraulic oil can change the high- and low-pressure chambers. Rotate the rotor in reverse. The sealing effect of the vane is the key to determine the performance of the vane swing hydraulic cylinder. In the...
