Description

Rotary engine is amassed in transfiguration

Technical field:

The present invention relates to a kind of power engine that heat energy can be changed into mechanical energy, is a kind of rotary engine.

Background technique:

Using at present comparatively general power engine has petrol engine and diesel engine, and they are applied to traffic and industrial and agricultural production widely as power source.But these two kinds of motors structurally all exist piston and connecting rod, and the exhaust gas pressure that their to-and-fro motion and exhaust valve are thrown open impacts, and causes them to occur inevitably vibrating and sending very big noise at work.The vibration of motor and noise corrupted we quiet living environment and working environments.People wish that the performance of motor is better, and have made very big effort, have also obtained some achievements on the improvement in performance of part.But the connecting rod of continuing to use for these years is retained so far all the time.The motor that people wait in expectation new occurs, and has also made huge effort, and the rotary polygonal piston engine of D.B.P. (people claims the wankel machine) is an example.But why it also is not widely used and appears in face of us, is its part that also comes with some shortcomings.The motor that people also wait in expectation new occurs.

Summary of the invention:

The long-pending rotary engine of transfiguration has adopted a kind of brand-new structure, is a kind of brand-new motor that does not have connecting rod and inlet and exhaust valve.It can eliminate vibration and the noise that common motor is difficult to avoid, and removes people in traffic, life in the hope of one action, and is reached vibration of several centuries and the tribulation that noise is brought in the working environment.The present invention has also simplified the structure of common motor, can reduce the manufacture cost of motor.

The structure of the long-pending rotary engine of transfiguration mainly is: with a pair of long-pending rotor of the transfiguration that can mesh mutually in the cylinder block that is installed in, in the running the transfiguration pneumatosis cylinder that forms is offered working medium and finish heat energy to mechanical conversion of energy.Power rotor is fixed on two main shafts, bearing for spindle supporting, two main shafts with the equal gear of a pair of number of teeth control power rotor to nibbling.In the place ahead of power rotor a pair of long-pending rotor of compressed-air actuated transfiguration that is used for is housed, provides pressurized air to the firing chamber with compression rotor.Between power rotor and compression rotor, the firing chamber is set.In the firing chamber, the fuel that sprays from fuel nozzle mixes with pressurized air, and when being ignited by the electric heat ignition head, burning is just gone on continuously, kills engine unless stop fuel supply.The firing chamber can be to the combustion gas of power rotor supply pressure, and a pair of power rotor is enclosed the combustion gas in the firing chamber transfiguration pneumatosis cylinder automatically during work, and volume of cylinder constantly enlarges the heat energy of pressure gas is changed into mechanical energy.The end of two power rotor main shafts is used to power output respectively and connects actuating motor, and the place that connects actuating motor also has driving mechanism to connect mutually with speed regulator.Sealing between power rotor, compression rotor and the cylinder block seals with mazy type mechanical clearance, and seal clearance is very little.A pair of power rotor can axially move back and forth, and the method that combines with mechanical transmission mechanism with sensor and control circuit is controlled the size of seal clearance automatically.

Usually in a single day the cylinder of conventional engine leaks, and the energy of gas will lose by exhaust.Can rotary engine accomplish that effectively sealing is a this motor key of success of decision, and leakage problem at first glance of the present invention has seemed an obstacle that is difficult to go beyond into it.But the mazy type mechanical clearance sealing configuration of exemplary application of the present invention, transfiguration pneumatosis cylinder has its unique distinction: the cylinder on the power rotor has a lot, pressure in the cylinders at different levels successively decreases step by step, the reduction of pressure difference helps reducing leakage intensity, the gas energy that is leaked in higher level's cylinder, part frictional heating when the gas travels through seal clearance, this part heat raise the state temperature of gas in the cylinder along with the gas that passes can enter in the next stage cylinder; By another part energy of gas leakage with the form of pressure along with the gas that passes is transferred in the next stage cylinder, the state pressure of gas in the cylinder is raise; That part of gas energy that every grade of cylinder leaks all can be continued to be used for work done by certain percentage in the next stage cylinder.This is just as fishing with the leaky block of multiple tracks, and the fish of leaking has the chance of being caught once more, has almost been caught up to the fish of leaking.When pressure gas is enclosed transfiguration pneumatosis cylinder automatically from the firing chamber, to power rotor is terminal opened wide when entering the exhaust circuit automatically till, the cylinder progression of going through can be determined in design in advance, is in operation even can makes the pressure of exhaust reach identical with barometric pressure.This special performance of transfiguration pneumatosis cylinder of the present invention the exhaust overbottom pressure is reduced, and exhaust leaving velocity also is subjected to the restriction of power rotor, so it can reduce the waste of energy in the waste gas.For sealing problem of the present invention, have muchly as long as have a look at the moving blades of steam turbine and gas turbine and the space between the static cascade blade, the misgivings of leaking for cylinder of the present invention will subtract greatly so, and will heighten to the confidence of applicability of the present invention.

The number of cylinders that power rotor of the present invention comprises is many, and does not have idle strokes such as air inlet, exhaust, so the power of motor unit weight is very big.Example of the present invention can also structurally be made multiple change on the basis of this basic principle.For example: the position of compression rotor can be changed on the overall structure of motor.Can lead to the combustion gas of power rotor supply pressure by insulated piping after moving outside the firing chamber.Compression rotor compressed and supplied air can pass through power rotor inside, is used for absorbing the heat that cools off power rotor and improves compressed-air actuated interior energy, and then improve the thermal efficiency of motor.The type of cooling of power rotor and sealing configuration also can be made change.In order to simplify patent document, do not describe in detail respectively at this.

The rotor of undertaking power output is exactly power rotor, and the moment of output comes from the rotor helical-screw song The tangential component that face produces under the gas pressure effect. So far, the function of capacity cylinder is very clear Chu.

Fig. 5 is the operation principle schematic diagram of capacity variable rotary internal combustion engine. The a pair of pressure of cylinder block 5 internal upper parts Contracting rotor 11 is compressed-air actuated, and this can use the capacity compression rotor to rotor, perhaps with reaching Same other compression rotors that require replace. The fresh air that compressed rotor sucks is after overcompression Be sent to combustion chamber 21. In the fuel mix of combustion chamber Air and supply, in drawing of electric heat ignition head 45 The lower continuous burning of combustion. The pressure gas that burning produces is enclosed automatically by a pair of capacity power rotor 7 and 8 Capacity cylinder 23, the continuous expansion working of combustion gas changes heat energy into mechanical energy in cylinder. Burnt Waste gas is opened wide automatically at the power rotor end, and waste gas just enters the exhaust circuit and starts by the exhaust outlet discharge Machine. At engine power rotor main shaft 6 and 9 a pair of equal-sized gear 30 their teeth of expression are arranged Number equates to nibbling. Gear and power rotor are fixed at main shaft, and what represent power rotor is subjected to one to nibbling Control to gear. The power rotor main shaft passes the compression rotor main shaft, the symbolic representation power that feather key connects Rotor main shaft can move at the inner axial reciprocating of the main shaft of compression rotor, and the rotation of power rotor can be passed through Feather key drives compression rotor and finishes nibbling. The cone of power rotor and cylinder block inner chamber all are taper, they Between the gap be can with the power rotor main shaft move axially control. This control is by such as square frame 49 Shown seal clearance automatic controls is finished. The a pair of taper roller axle that the top of compression rotor fills Holding the expression compression rotor axially can not move. The end of two power rotor main shafts is used as respectively power output Be used for to connect actuating motor, the place that connects actuating motor also has speed regulator to connect mutually. Speed regulator is used for controlling The work of engine processed.

The schematic of Fig. 6 shows the main structure of the long-pending rotary engine of transfiguration.Cylinder block 5 is equipped with in engine housing 3 inside, and cylinder block is made with stupalith can be high temperature resistant, can also reduce the heat transfer loss.The long-pending power rotor 7 and 8 of the transfiguration that a pair of ceramics material or other exotic materials are made is separately fixed on two combined type main shafts 6 and 9, and rotor can intermesh, and these two main shafts are exactly the power rotor main shaft.The combined type main shaft mainly is serrations 27 connections with transition fit. Main shaft 6 and 9 passes main shaft 14 inside that the rotor that contracts is overstock in two transfigurations respectively, and gap each other is very little, and the power rotor main shaft can reciprocatingly slide in its inside, and with profile of tooth feather key 12 each other moment of torsion is passed to main shaft 14.A pair of transfiguration is overstock the rotor 11 that contracts and is fixed on the main shaft 14.The gear 30 that a pair of number of teeth equates also is housed on the power rotor main shaft, and they are positioned at gear-box 1 inside, gear can guarantee simultaneously power rotor and compression rotor to nibbling requirement.Also have impeller 13 and air passageways on the compression rotor main shaft, these passages are communicated with power rotor main shaft inner chamber 25.The axial position of compression rotor is limited by end cap 15 by bearing 16, axially can not move.A pair of power rotor main shaft can axially move back and forth, and is used for controlling the seal clearance size between power rotor and the cylinder block.A pair of power rotor main shaft can axially reciprocatingly slide in the inner ring the inside of bearing 29 and 39, because gap each other is very little.The radial position of above-mentioned two kinds of rotor main shafts all is subjected to the common restriction of bearing 29,39 and 16.Above-mentioned two kinds of rotors were all done dynamic balancing and were handled, and excavation has light weight hole 4 and 18 respectively on them, can mend balancing weight (pattern omission) by replacing a damaged part in their proper site in addition.Above-mentioned two kinds of rotors are when work, and their transfiguration pneumatosis cylinder is dynamically to move to exhaust circuit direction.Power rotor main shaft 6 and 9 axial position are limited by the thrust ball bearing 38 of gear-box inside.Thread bush 37 is installed between a pair of thrust ball bearing 38, can move back and forth vertically together with bearing and main shaft, the outside thread 31 of its left end can bear the end thrust of power rotor, outside thread connects with the flange 32 usefulness screw-thread fit that have internal thread, and the end thrust of outside thread 31 is just born by flange 32.Moving axially of thread bush 37 is that worm screw 34 driven by stepper motors drives worm gear 36 rotations, and the rotation that the feather key 35 that is slidingly connected by profile of tooth drives thread bush 37 is finished.When stepper motor is done positive and negative rotation, thread bush just can be done corresponding positive and negative rotation, the axial advance and retreat that take place when thread bush 37 rotates in the internal thread of flange 32, but just the propulsion power rotor main shaft axially moves back and forth.Thereby finish the seal clearance control between power rotor and the cylinder block 5.The radial position of thread bush 37 is definite with being slidingly matched by the external diameter of the internal diameter of worm gear 36 and sliding bearing 33.(sliding bearing 33 also available radial rolling bearing replacement is finished identical functions, and use is for the simplified-file figure herein)

Can also find that in Fig. 6 sealing configuration 10 everyly need all be equipped with to the position that air-flow and lubricant oil seal in some positions on air flue position and the gear-box 1 throughout, the seal ring that various different purposes are housed is being represented in this kind signal.(do not express oil supply systems such as oil leab, oil pump among Fig. 6, can use for reference because of mature technique and be applied to this, the present invention omits.)

The end 40 of power rotor main shaft 9 is used to connect actuating motor and speed regulator, and speed regulator is used for controlling the work of motor.(mechanical transmission structure of this part and governor structure, conventional design can solve, and the present invention omits.) end 41 of power rotor main shaft 6 is used as the interface of power output, the profile of tooth splined section of only drawing herein.(remaining part omits.) but these two axle heads 40 and 41, when the seal clearance between power rotor and the cylinder block is carried out auto-control, have and move axially.

After the long-pending rotary engine of transfiguration was started, mechanical transmission mechanism just worked.Under the common pump-absorb action of a pair of centrifugal impeller 13 and a pair of compression rotor, fresh air enters circuit through the connecting tube of air-strainer from air inlet road junction 20.Air by behind the circuit along the arrow indicated direction, concentrate at gas collection circuit 28 in the passageway 22 of crossing between cylinder block and the engine housing, continues to enter from radial direction the hollow lumen 25 of power rotor main shaft then.Have cooling hole 24 on the internal chamber wall, the structure shape of inner chamber makes the air by inner chamber produce part air ring stream, and circulation passes hole 24 cooling power rotors.The passage that the air of process inner chamber 25 passes between between centers duct and the centrifugal blade 13 enters circuit 17.The transfiguration pneumatosis cylinder 19 that constantly forms during the compression rotor running is enclosed cylinder to the air in the circuit automatically from rotor tip and is compressed; Air through overcompression is opened wide automatically from the other end of rotor, and enters firing chamber 21 continuously.Pressure when motor has just started in the firing chamber is not high, because compression rotor and power rotor are playing a part intake and exhaust simultaneously.In the firing chamber, in case burn by spirt fuel and by igniting, the temperature and pressure in the firing chamber just rises rapidly.Burning in the firing chamber is continuous, and this combustion manner can be simplified the fuel supply system of common internal-combustion engine and the ignition system of gas and oil machine greatly.The pressure gas that continuous burning produces is enclosed transfiguration pneumatosis cylinder 23 automatically by the power rotor, burns in cylinder and can also proceed.These characteristics of power rotor transfiguration pneumatosis cylinder are for very advantageous conditions has been created in the abundant burning of fuel.The a series of more bigger transfiguration pneumatosis cylinder of power rotor is when rotor turns round, and its swept volume constantly increases, so the pressure gas in the cylinder just constantly discharges its heat energy and finishes to mechanical conversion of energy.The waste gas of finishing merit amasss inblock cylinder to circuit 26 from the unlimited automatically transfiguration of the other end quilt of power rotor, and circuit communicates with outlet pipe road junction 2.

Fig. 7 is that the G-G among Fig. 6 analyses and observe, in the sectional view of Fig. 7 as can be seen the section shape of firing chamber and in Fig. 6 visible air passageway 22 be distributed in the situation of Fig. 7 periphery.Pilot chamber 42 in the firing chamber can be with the fuel and the air mixing of fuel nozzle 43 ejections, and mixed gas can be lighted with electric heat ignition head 45, and nozzle 43 usefulness are communicated with pipe joint 44 fuelings of fuel supply system.(about fuel supply system, the concrete structure of pilot chamber and firing chamber, the successful experience of aeroengine and gas turbine can be applied to this by reference, and does technical the linking with the present invention, and content is omitted.)

Fig. 8 is that the H-H among Fig. 6 analyses and observe, and the visible road junction 2 that radially connects is exactly the port of this sectional view outlet pipe 47 in Fig. 6, and outlet pipe is installed on the engine housing.Visible exhaust circuit 26 in Fig. 6 is made the end envelope of exhaust circuit with the sealing cover 48 of ceramics material in this figure.Resistant to elevated temperatures seal ring 46 is housed between sealing cover 48 and outlet pipe prevents that waste gas from leaking into intake duct.

Fig. 9 is the I enlarged view among Fig. 6, and the long-pending power rotor 8 (7) of two transfigurations is equipped with two sensor gap measuring heads (this exemplary application capacitive transducer) as shown in Figure 9 respectively with the axial corresponding position of cylinder block 5.The sheet metal that the local curved surface of two surface configurations and power rotor matches is installed in above them (herein also can with other functionally similar sensor replacements), under the less situation in gap, these two sheet metals can consist of capacitor, derivative respectively lead is exactly two electrodes 53,51 of capacitor from two sheet metals.The size of gap S can be used for reflecting the size of seal clearance between power rotor and the cylinder block.S changes when the gap, and the size of electric capacity also just changes.The electrode 53,51 (52,50) of two capacitors is drawn standby (for simplify patent document, figure omit) with lead with two respectively on the insulation commutator that power rotor is set up on cylinder block.These two electrodes are just as sensor electrode, the clearance measurement head that these two capacitors are exactly sensor.

Simplified electrical circuit diagram shown in Figure 10 is exactly from power rotor and the derivative electrode 53 of cylinder block difference among Fig. 9,51 (52,50) as the electrode of the measurement by capacitance head of sensor, the gap signal that it reflects amplifies by electron-amplifier and becomes electrical pulse, and electrical pulse is used for drive stepping motor and makes the simplification circuit diagram of positive and negative rotation.Figure 10 shows that two power rotors have sensor 55 (54) and electron-amplifier 57 (56) separately, and the electrical pulse of generation leads to the stepper motor D59 (D60) that Liang Tai is connected in parallel through behind the control circuit 58.Be connected in parallel and improve the Security of engine operation, and guarantee that the side clearance between a pair of power rotor equates to prevent mutual interference.

Figure 11 is the J enlarged view among Fig. 6, and all there is radial and axial gap at its every kind of rotor engagement position each other of signal, and U is a warp spacers, and V is an axial clearance.The gap of this reservation is the smaller the better, but interlock can not take place will guarantee work the time under maximum heat expansion situation.

Figure 12 be the cylinder surfaces among Fig. 6 K to launch to view (P that comprises rotor to, Q to, R to and the rotor conical surface launch to view).The roundlet of these dense distribution among Figure 12, the signal part surface has been done the processing of labyrinth gap sealing configuration, and roundlet is represented aperture, and (also available other hole shapes) have the more shallow degree of depth.When engine operation, between two very little part surfaces of seal clearance, air-flow will pass very difficult from these seal clearances.Air-flow passes from the gap and will bump with countless little hole walls, and produces the little eddy current of mixed and disorderly air, and the mixed and disorderly molecular bombardment of the little eddy current of air causes very big resistance to the gas that passes from the slit.Particularly between two kinds of rotors and cylinder block surface, the rotation of rotor makes that the air in the aperture of countless labyrinths bounces mutually between rotor and the cylinder block.This bouncing to gas leakage erected the resistance wall one.The combustion gas that comes from the firing chamber will enter another cylinder from a cylinder, and the leap of multiple tracks is exactly a big labyrinth on macroscopic view, has said nothing of these apertures.Clearance seal mechanism of the present invention that Here it is.

The seal leakage meeting of compression rotor when work consumes shaft work, but it leaks the merit that is consumed, and can change the heat of pressurized gas into.Heat raises compressed-air actuated temperature, and this part additional temperature major part has been transferred to the firing chamber, and the gas internal energy in the firing chamber is increased.The energy that two kinds of seal leakages of this that occurs on compression rotor and power rotor take place shifts, and each has the means of recovery and reuse.

Through above introduction to the long-pending rotary engine of transfiguration, and utilize the further specifying that the example of accompanying drawing makes can be clear, the structure of the long-pending rotary engine of transfiguration be different with other existing motors.It has following characteristics and advantage: it has cancelled requisite connecting rod of ordinary internal combustion engine and distribution device, replaces the long-pending rotor of two pairs of transfigurations; The exhaust gas pressure that it does not have explosion stroke and exhaust valve to throw open and causes impacts, thereby makes that vibration and noise that common engine produced have all been eliminated basically.This motor can also prolong the combustion process of fuel, because of combustion gas can stop the long period in transfiguration pneumatosis cylinder, allows burning carry out more fully.The long-pending rotor of the transfiguration that its is used makes the continuous air feed of motor, continuous burning, and the mode of work done is achieved continuously.Therefore it can simplify the fuel supply system of ordinary internal combustion engine and the ignition system of gas and oil machine.Its application can also reduce the requirement of motor to fuel performance, and is that motor creates favorable conditions to the transition of using gases fuel from using fuel oil.It is more that this motor participates in the number of cylinders of work done at work simultaneously, can send bigger power, therefore can significantly reduce the engine weight of unit horsepower.It is contrasted with steam turbine and gas turbine: its rotating speed is relative to low, because its labyrinth seal structure provides the condition that reduces rotating speed for it.Its exhaust overbottom pressure can be set when design as required in advance, even can accomplish to be equal to barometric pressure; It is also low than steam turbine and gas turbine that its exhaust leaving velocity is subjected to the restriction of power rotor, and this is very favourable to the thermal efficiency that improves motor.Its rotating speed is between ordinary internal combustion engine and gas turbine.
