Embodiment 1

[0012] Combine below figure 1 Embodiment 1 of the invention will be further described. This embodiment is a device for cyclically increasing and decreasing the volume of a closed cavity with hinged blades.

[0013] Depend on Figure 1-Figure 2 It can be seen that the inner rotor 15 is a cylinder, and the two sets of bearings and sealing device assemblies 1 and 14 matched with it are installed on the left and right end covers 2 and 13 respectively at the two ends of the axis of the cylinder; 10 sets of outer rotors and inner rotors On the outer cylindrical body, the two matching inner rings 4 and 11 of the outer rotor are annular cylinders, the outer diameter of the cylinder is the same as the inner diameter of the outer rotor end, and the outer surface of the annular cylinder is statically connected to the inner surface of the outer rotor end. Cooperate, the inner rings of the two outer rotors are respectively fixed at the two ends of the axis of the outer rotor, the inner ...

Abstract

The invention provides a double-rotor sealed cavity volume circulated increasing and decreasing device which is mainly characterized in that an inner rotor is a cylinder. Two sets of bearing and sealing device assemblies matching the inner rotor are arranged on two ends of the axis of the cylinder, and are respectively arranged on left and right end caps. The outer diameters of cylindrical sleeve rings are the same with the inner diameters of the ends of the outer rotor. The outer sides of the cylindrical sleeve rings statically match the inner sides of the ends of the outer rotor. Two inner sleeve rings of the outer rotors are respectively fixed on two ends of the axis of the outer rotor. The inner sleeve rings of the outer rotor and two matching sets of bearings are arranged on two ends of the axis of the cylinder. The axis of the inner rotor is parallel to but not coaxial with that of the outer rotor. The device has the advantages that rotor vane radial edge, outer rotor inner side wall, and inner rotor inner wall are not abraded, such that service life is long; pressure of liquid outputted by a pump can be increased by more than 3 times than that of a traditional vane pump; torque outputted by a motor can be increased by more than 3 times than a traditional vane motor. The device is used in the field of liquid pump, hydraulic motor or internal combustion engine manufacturing.

Description

technical field [0001] The invention relates to a double-rotor closed cavity volume cycle increase and decrease device, in particular to a double-rotor closed cavity volume cycle increase and decrease device separated by a plurality of hinged, jointed or elastic blades. Background technique [0002] At present, when the blades of vane pumps and motors rotate coaxially with the rotor, the outer edge of the blade must be in close contact with the inner wall of the cylindrical stator as much as possible, and slide on the inner wall throughout the process. This sliding makes the outer edge of the blade And the inner wall of the stator is worn, reducing the service life of the pump or motor; in view of the poor sealing of the volume space of the pump or motor, it is difficult to increase the output pressure of the pump and the output torque of the motor, and the performance of the pump or motor is unstable when it is running at low speed. When the piston pump, motor, and internal...
