The flexible rotor vacuum pump is simple in structure, easy to process and manufacture, high in operation efficiency and wide in energy-saving universality, and is a flexible rotor vacuum pump wide in universality.
Description
Technical field
The invention belongs to positive displacement technical field, particularly relate to a kind of flexible rotor vacuum pump; For pumping vacuum pump, compressor, the pneumatic motor of various gas medium.
Background technique
At present, domestic and international normally used vacuum displacement pump mainly contains: sliding-vane-type vacuum pump and rotary-vane vaccum pump.Higher and the inefficiency of above-mentioned vacuum displacement pump complex structure manufacture cost.
Summary of the invention
Goal of the invention: the invention provides a kind of flexible rotor vacuum pump, its objective is the problem that solution is in the past existing.
Technological scheme:
A kind of flexible rotor vacuum pump, is characterized in that: this vacuum pump comprises the pump housing, front cover and rear end cover; Front cover and rear end cover are arranged on the rear and front end of the pump housing, and pump body is cavity; Flexible rotor is provided with in this cavity; Flexible rotor radial direction is evenly distributed with multiple flexible rotor body; Multiple flexible rotor external surface and pump housing cavity inner wall tangent and form several dynamic point of contact, be formed centrally throw of eccentric in the center of flexible rotor and the pump housing; Pump housing cavity is divided into several independently chamber by the flexible rotor body of flexible rotor; Pump housing sidewall is provided with and the suction port of the cavity connects of the pump housing and exhaust port; Flexible rotor and main shaft are connected and fixed and with the central rotation of main shaft around flexible rotor.
The cavity of the pump housing is circular or oval.
Flexible rotor body is four, flexible rotor external surface and pump housing cavity inner wall tangent and form four dynamic point of contacts A, B, C, D pump housing cavity is divided into four independently chambers.

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is side sectional view of the present invention;
Fig. 3 is flexible rotor nature structural representation of the present invention;
Fig. 4 is the structural representation of the another kind of form of flexible rotor.
embodiment:
First by reference to the accompanying drawings the present invention is described further:
The invention provides a kind of flexible rotor vacuum pump, this vacuum pump comprises the pump housing 1, front cover 5 and rear end cover 6; Front cover 5 and rear end cover 6 are arranged on the rear and front end of the pump housing 1, and the pump housing 1 inside is cavity, and this cavity is circular or oval; For circular cavity, in this circular cavity, be provided with flexible rotor 2; Flexible rotor 2 radial direction is evenly distributed with multiple flexible rotor body F(herein for four); The radial equally distributed multiple flexible rotor body of flexible rotor 2, flexible rotor external surface and the pump housing 1 cavity inner wall tangent, flexible rotor 2 center O2 and the pump housing 1 center O1 forms eccentric distance e; Multiple flexible rotor external surface of flexible rotor 2 radial direction and the pump housing 1 cavity inner wall tangent and A, B, C, D of being formed in several dynamic point of contact such as figure; The pump housing 1 cavity is divided into several independently chamber as I in figure, II, III, IV by flexible rotor 2; The pump housing 1 sidewall is provided with and the suction port 4 of cavity connects and exhaust port 3; Flexible rotor 2 and main shaft 7 are connected and fixed and rotate around O2 with main shaft 7.
Embodiment: as shown in Figure 1, flexible rotor 2 is the overall structures be made by beformable body elastic material, as shown in Figure 3; Multiple flexible rotor body F outer surface of flexible rotor 2 radial direction and the pump housing 1 circular cavity tangent and form 4 point of contacts A, B, C, D; The pump housing 1 circular cavity is divided into 4 independently chambers by flexible rotor 2, is respectively I, II, III, IV, as shown in Figure 1.When main shaft 7 drives flexible rotor 2 to rotate around O2 by direction as shown, the volume of several autonomous closure chamber changes from small to big and gas medium is sucked by suction port 3 by cyclically-varying from large to small, discharges through exhaust port 4; Periodically constantly gas medium is sucked by suction port 3 by change, discharges through exhaust port 4; Realize it and working procedure is pumped to gas medium.Fig. 4 is the form of the another kind of linkage structure of the nature of flexible rotor 2, and flexible rotor body F is arranged on flexible rotor 2.
The simple manufacturing of structure of the present invention easy operational efficiency height energy-saving universal is extensive.
