Abstract

The invention relates to a vacuum cycloid vane motor. The vacuum cycloid vane motor utilizes the flow of air in a container to generate a pressure difference to promote the rotation of vanes and enables the torque to be axially output by a rotor. The gas pressure difference is generated by the decrease of pressures in cavities because gases in the cavities at one ends of the vanes are discharged by a vacuum pump; and gases inevitably enter the other ends of the cavities to supplement because of the presence of the atmospheric pressure, so the rotor rotates in cycles.

Description

Vacuum cycloid sliding-vane motor

Technical field

The present invention relates to a kind of vacuum cycloid sliding-vane motor, its working medium is atmosphere, vacuum system and cycloid sliding-vane motor unite two into one and consist of the pneumatic motor that is operated under the atmospheric pressure state, and motor inside is separated into the atmosphere chamber of variable volume vacuum chamber and variable volume by blade; Extract atmosphere in the vacuum chamber out cavity pressure during vacuum system work and descend, the logical atmosphere of atmosphere chamber namely can promote blade rotary.

Background technique

The air intrinsic pressure easily flows again, can produce pressure difference in the effect current downflow of external force, even the atmosphere under constant volume state has on a small quantity is discharged from, and all can cause the stressed rapid increase of container wall.

Summary of the invention

The present invention is comprised of cycloid cylinder body, built-in rotor, blade, end cap, vacuum system, the quantity such as the quantity of blade and cylinder body hypocycloid face; Blade is embedded in the rotor rollaway nest and with spring pre-tightening vane tip and cycloid face is fitted, thereby consists of several variable volume chamber: one for variable vacuum compartment through exhaust passage and vacuum system binding, one be variable atmosphere chamber its directly communicate with atmosphere; It is whole that vacuum system, cycloid sliding-vane motor are linked as a sealing with connecting piece, can also be arranged apart and use pipe link.When vacuum system starts with vacuum chamber in atmosphere discharge, the vacuum chamber internal pressure descends, atmosphere enters and promotes blade rotary in the atmosphere chamber, entirely acts on blade for making atmospheric pressure, so adopt the cycloid face to reduce the pressure loss.

Because when adopting the rotation of cycloid face blade drive rotor, blade can periodically shrink in rotor, barometric pressure is zero rotor meeting stall to blade pressure in the time of in vanes retract is advanced rotor, be zero for overcoming blade pressure, can adopt some groups of sliding-vane motors are the method that multiple angles is arranged the formation phase angle at same output shaft, so just can not make the rotor stall, output torque is larger simultaneously; Vacuum system is comprised of motor and vacuum pump, because sliding-vane motor scavenging volume is greater than vacuum pump scavenging volume several times, decades of times, when vacuum pump is worked like this, the rotating speed of motor will be lower than rotating speed several times, the decades of times of vacuum pump, because vacuum pump is operated in negative pressure state, vacuum pump can make with very low energy consumption motor output be higher than its energy consumption several times, decades of times even higher energy like this.

The present invention is implemented by following technological scheme:

A kind of vacuum cycloid sliding-vane motor

Comprise: vacuum system, organize the cycloid sliding-vane motor more and combine; The vacuum system bleeding point is combined with cycloid sliding-vane motor relief opening and is consisted of the exhaust passage, the gerotor motor suction port is logical atmosphere directly, blade is embedded in the rotor, and there is spring pre-tightening to be installed in the cycloid cylinder body, the external diameter of rotor overlaps with cycloid two arc intersection points, consists of N cavity volume, and the number of blade equates with the cavity volume number, many group sliding-vane motors separate into the phase angle with end cap and are fixed on the axle, so not only can increase moment of torsion but also can overcome the dead point.

Good effect of the present invention:

1, utilizes the atmosphere intrinsic pressure in the cavity volume of sealing, to flow and promote the blade acting;

No matter vacuum pump power, air displacement size output torque is substantially constant;

2, vacuum system is operated in negative pressure state, and energy consumes little;

3, organize the power that sliding-vane motor produces more and exported by an axle, the large pulsation of output torque is little;

4, because dynamic medium is atmosphere, the air that the frictional heat that produces during rotation is easily flowed is taken away, and can not produce high temperature;

5, all material easily obtains, processing, and it is convenient to make;

6, can be used as stationary power or mobile power.

Description of drawings

Below in conjunction with accompanying drawing to the detailed description of the invention:

Fig. 1 is structural representation of the present invention;

Fig. 2 is that the right sectional view of the A-A of Fig. 1, Fig. 3 are the left sectional view of B-B of Fig. 1;

Among the figure: 1 rotor, 2 springs, 3 blades, 4 cylinder bodies, 5 end caps, 6 seal rings, 7 vacuum chambers, 8 vacuum pumps, 9 inlet holes, 10 combination exhaust holes, 11 main pipes; 8-1 air-inlet of vacuum pump, 8-2 vacuum pump exhaust port.

Embodiment

As shown in Figure 1, 2, 3: its cylinder body 4 internal surfaces of a kind of vacuum cycloid sliding-vane motor are to intersect the cycloid face that surrounds by many cycloids to form, and blade 3 is pressed in the groove that is embedded in rotor 1 and is contained in the cylinder body 4 with spring 2 pre-tightening sleeves; Blade 3 is close to cylinder body hypocycloid face and can be stretched in rotor freely when rotor 1 rotation on its top under the effect of spring 2; The two ends that 6 sealings of end cap 5 usefulness seal rings are sleeved on the output shaft of rotor 1 also make the cylinder body 4 inner N of formation the fixed volume chambers that formed by end cap 5, rotor 1 and rotor 1 and the applying of cycloid intersection point with bolt and cylinder body 4 fastening encapsulation; Blade 3 is in that it is divided into 2N variable volume chambers atmospheric air chamber, vacuum chamber with fixing chamber volume during rotary extension in the cycloid face with rotor 1; Atmospheric air chamber directly communicates with atmosphere by inlet hole 9, and vacuum chamber 7 communicates with vacuum chamber 7 through main airway 11 by combination exhaust hole 10; The combination of many group gerotor motors is convenient to for reserving exhaust port in combination exhaust hole 10; Vacuum pump 8 connects and composes vacuum motor by vacuum chamber 7 and cycloid cylinder body, and vacuum pump 8 is by motoring.
