Description
Technical field
What the present invention relates to is that a kind of rotation shell type rotates pendulum engine without pause.Its technology both can be used for conventional engine field, can be used as again a kind of novel micro power source power system.This technology is mainly concerned with the design of differential drive mechanism in two-gyro pendulous motor, by changing planetary gear construction velocity ratio, central gear or gear ring rotating speed, make two rotor blades do the compression and expansion forming cavity volume without the relative differential paused catches up with motion, realize the working procedure of the thermal machines such as compression, burning, expansion work thus.Because engine rotor running reduces without the impulsive load of pausing, running, it is simple that the present invention effectively can improve structure, compact dimensions, significantly loss of weight; Without large-mass member to-and-fro motion, be beneficial to high speed operation and operating life raising; Rotor makes running speed high without pause running, and output power and moment of torsion are larger, and power to weight ratio is higher.
Background technique
As dynamic origin modal in daily life, current piston engine mainly contains reciprocating-piston engine and rotary piston engine two kinds.Reciprocating-piston engine is full-fledged, structure is simple, the thermal efficiency is high, applicability is strong, apply the most widely although obtained at present, but the reciprocal inertia force of its piston can with rotating speed quadratic growth, therefore its working speed can not be too high, limit the power stage of such motor, and then cause its power to weight ratio low.Cylinder is divided into some cavity volumes by rotary piston engine, and rely on rotor to bear the external output torque of cylinder pressure, in each cavity volume, work cycle is identical with reciprocating, and rotor only does unidirectional rotary motion.Therefore, it structurally can either keep the Economy of Reciprocating engine, is easy to again break away from shuttle inertial force problem and be beneficial to speed up.Rotary piston engine has certain advantage, also been proposed kinds of schemes both at home and abroad, as at the uniform velocity type, planet-shaped, differential type.Wherein, three lobe rotor piston engine has ripe technical products and occurs, automobile and unmanned plane field have also been obtained applying to a certain degree.
Traditional reciprocating-piston engine and rotary piston engine all also exist the puzzlement that power to weight ratio is low, specific power is little, and also there are some defects in novel rotary engine scheme, as double rotor piston engine has instantaneous dwell characteristic, power performance is not good; The tightness problem that rotary polygonal piston engine produces due to linear sealing hinders it and further develops.
If but heat engine is microminiaturized, because hydrocarbon fuel energy density is high, overall engine specific power can significantly promote, and fuel source is extensive in addition, builds the micro power source power system great potential based on heat engine.In recent years, developing rapidly of micro-machining techniques, also for micropower system brings wide development space.Current, world many countries all accelerates the paces of development micro internal combustion engine, and various forms of micro internal combustion engine model machine is come out one after another, as miniature gas turbine, miniature pendulum internal combustion engine, miniature rotor internal-combustion engine etc. based on Wankel rotary engine.But output power and the efficiency of above-mentioned micro power source power system are still lower, all not yet form ripe product.
In summary, be necessary to design a kind of rotation pendulum engine without pausing, make it the unfavorable restriction that can not only break through conventional engines because not having large quality to build to-and-fro motion, and rotor operation is without pause, the defect of rotor instantaneous dwell mechanism can be overcome, running speed is higher, power to weight ratio is also higher, and is easy to microminiaturized.

Technological scheme of the present invention is further described below in conjunction with accompanying drawing:
Fig. 1, gives rotation shell type and rotates pendulum engine general structure schematic diagram without pause.Concrete structure as shown in Figure 2,
The rotation shell type that the present invention proposes rotates pendulum engine without pause and adopts dual-rotor structure form, the hollow shaft of the corresponding large radius of left side B rotor 10, the solid shaft of the corresponding minor radius of right side A rotor 4.Its general structure mainly comprises a pair rotor, A rotor 4, B rotor 10, ram 3, a pair fourbar linkage 15, planetary gears 16, control system, premixed device (see figure 1), additional drive device (see figure 1), lubrication system, cooling system.Two rotor coaxials are staggered installation of, and each rotor is all with N number of vane-piston, and cylinder body is divided into 2N the cavity volume that works alone, each vane-piston has certain thickness angle; Ram 3(aperture arrangement is shown in Fig. 3) with suction port 9, relief opening and lighting-up tuyere, the relative position of they and cylinder body is fixed, and suction port directly passes into premixed fuel, and waste gas is directly entered air by relief opening, and both are all without the need to control valve; Premixed device (see figure 1) two entrances are connected with fuel, air respectively, both the stoichiometric ratio control flow of based on fuel, ram is passed into after they are fully mixed, its outlet is connected with the suction port of ram, completes the typical quartastroke engine work cycle of air inlet, compression, burning expansion acting, exhaust in active chamber; Two fourbar linkages 15 are crank rocker, and their opposed installations, because having phase difference
π, respective rocking bar can catch up with the angular velocity differential of mechanical periodicity when crank uniform rotation, and rocking bar
c0(see figure 4) and B rotor 10 are consolidated, rocking bar
c ' 0(see figure 4) and A rotor 4 are consolidated; Planetary gears 16 adopts outer gearing form herein, and planet wheel and fourbar linkage crank are consolidated, and its effect essence is to the speed-raising of fourbar linkage entirety, is fourbar linkage and provides a velocity of moving space, realize two-spool rotary oscillation; Output shaft 14 is connected with the frame (see figure 4) of fourbar linkage, fuel combustion chemical energy is utilized externally to do work, additional drive device (see figure 1) is drawn by output shaft, controls power cylinder 3 rotate with certain velocity ratio, ensures that the relative position of suction port, relief opening and lighting-up tuyere and cylinder body is fixed; When fourbar linkage moves to a certain position, relevant work chamber (the C chamber as in Fig. 5) volume reaches minimum, and active chamber inner pressure ratio meets needed for fuel, and Iganition control system is used for the accurate control points fire time, and twice, front and back firing interval is
π/
n(N is vane-piston number); As previously mentioned, fuel and the air mass flow of premixed device (see figure 1) two entrances need meet equivalent proportion requirement, need flow control system; Lubrication and cooling system is then common additional mechanism providing additional operation.
The rotation shell type that the present invention proposes rotates pendulum engine without pause, and its power transmission mechanism is made up of energy conservation component (see figure 3) and differential driven unit (see figure 4).As shown in Fig. 3 (for each rotor containing 2 vane-pistons), energy conservation component, comprise cylinder block and coaxially intersect two rotors be arranged in cylinder block, if rotor is evenly equipped with N number of vane-piston, two groups of vane-pistons are spaced in cylinder block, form the individual airtight chamber that works alone of 2N altogether.Between two rotors, relative movement is that differential catches up with, each working chamber volume generating period change, and being similar to the piston-engined volume of cylinder change of four-stroke, is the kinetic energy of rotor by the thermal energy of fuel combustion, thus realizes the continuous operation circulation of motor.As shown in Figure 4, differential driven unit is combined by planetary gears and crankrocker mechanism.Planetary gear construction makes output shaft and crank with certain velocity ratio work, and the rocking bar with two crankrocker mechanism of phase difference π is connected with respective rotor respectively.Their collaborative works, two rotors be responsible in constraint cylinder catch up with relative movement with the angular velocity of cyclic fluctuation as differential, keep an angular velocity forward all the time simultaneously, meet motor without pause kinetic characteristic.
Due to the opposed installation of fourbar linkage, at any one time, must be that a rocking bar relative main is forward instantaneous, another be backward instantaneous, and its absolute velocity is that respective relative velocity superposes a spindle speed.If the speed of autorotation of the relative output shaft of given small gear and the ratio of output shaft rotating speed
ρ, in crankrocker mechanism crank and rocking bar speed ratio extreme value [-
m,
n], then the differential that the relative size relation of absolute values both determines two rotors catches up with characteristic.Its rule is: if the relative rollback speed maximum value of instantaneous rocking bar is backward greater than spindle speed, then motor two rotor replaces rollback in the course of the work; If the relative rollback speed maximum value of instantaneous rocking bar backward equals spindle speed, then motor two rotor replaces instantaneous dwell in the course of the work; If the relative rollback speed maximum value of instantaneous rocking bar is backward less than spindle speed, then motor two rotor in the course of the work all the time forward, has without pause characteristic.There is excessive sudden change of acceleration in first two forms of motion, and mechanism is without when pausing, and its acceleration change is tending towards relaxing, and running is more steady, and power performance is improved.Consider the advantage of fourbar linkage without quickreturn characteristics, the necessary controlling rod of engine design is long, causes its speed ratio extreme value to regulate.
Therefore, effectively changed by two kinds of methods
ρthe size of value, makes motor two rotor have without pause characteristic: (1) changes gear ratio; (2) central gear or gear ring rotating speed is changed.Notice: for outer gearing planetary gear train, velocity ratio is negative,
ρvalue will with the reverse speed ratio ratio of extreme values of fourbar linkage comparatively, namely according to-
mregulate
ρ; For internal gearing structure, velocity ratio is just,
ρvalue will with the forward speed ratio ratio of extreme values of fourbar linkage comparatively, i.e. basis
nregulate
ρ.
