Actuating device (see figure 1), lubricating system, cooling system.Two rotor coaxials are staggered installation of, and each rotor is all lived with N number of blade
Plug, is divided into 2N the cavity volume that works alone by cylinder body, and each vane-piston has certain thickness angle；Power cylinder 3(opening cloth
Put and see Fig. 3) with air inlet 9, air vent and lighting-up tuyere, they are fixed with the relative position of cylinder body, and air inlet is passed directly into pre-
Mixed fuel, waste gas is directly discharged into air by air vent, and both of which is without control valve；Two entrances of premixed device (see figure 1) respectively with
Fuel, air are connected, and control both flows according to the stoichiometric ratio of fuel, are passed through power after being sufficiently mixed them
Cylinder, its outlet is connected with the air inlet of power cylinder, completes air inlet, compression, burning expansion acting, the allusion quotation of aerofluxus in working chamber
Type quartastroke engine cycle of operation；Two four-bar mechanisms 15 are crank rocker, and they opposed installations, because having phase contrastπ,
Respective rocking bar can pursue with the angular velocity differential of mechanical periodicity when crank uniform rotation, and rocking barC0(see figure 4) turns with B
Son 10 is consolidated, rocking barC’0(see figure 4) is consolidated with A rotor 4；Planetary gears 16 uses external toothing herein
Form, planetary gear is consolidated with four-bar mechanism crank, and its effect essence is to raise speed to four-bar mechanism entirety, is four bar machines
Structure provides a velocity of following, it is achieved two-spool rotary oscillation；Output shaft 14 is solid with the frame (see figure 4) of four-bar mechanism
Even, utilizing fuel combustion chemical energy externally to do work, additional drive device (see figure 1) is drawn by output shaft, with certain gear ratio
Control power cylinder 3 to rotate, it is ensured that air inlet, air vent are fixed with the relative position of cylinder body with lighting-up tuyere；Four-bar mechanism moves
During to a certain position, relevant work chamber (the C chamber as in Fig. 5) volume minimizes, needed for working chamber inner pressure ratio meets fuel, and point
Ignition control system is used for the accurate control points fire time, and front and back twice firing interval isπ/N(N is vane-piston number)；As front
Described, fuel and the air mass flow of two entrances of premixed device (see figure 1) need to meet equivalent proportion requirement, need a flow-control system
System；Lubrication and cooling system is then common additional mechanism providing additional operation.
The present invention propose rotation shell type without pause rotate pendulum engine, its power transmission mechanism by energy conservation component (see
Fig. 3) constitute with differential driving assembly (see figure 4).As shown in Fig. 3 (as a example by each rotor is containing 2 vane-pistons), energy is changed
Assembly, comprises cylinder block and two rotors being arranged in cylinder block that coaxially intersect, and lives if being evenly equipped with N number of blade on rotor
Plug, two groups of vane-pistons are spaced in cylinder block, form 2N the airtight chamber that works alone altogether.Relatively transport between two rotors
Moving and pursue for differential, each working chamber volume generating period changes, and is similar to the volume of cylinder change of four reciprocating piston electromotors,
The heat energy of fuel combustion is converted into the kinetic energy of rotor, thus realizes the continuous cycle of operation of electromotor.As shown in Figure 4, differential
Assembly is driven to be combined by planetary gears and crank and rocker mechanism.Planetary gear construction makes output shaft and crank with necessarily
Gear ratio work, have phase contrast π two crank and rocker mechanisms rocking bar respectively with respective rotor be connected.They work in coordination with work
Making, two rotors being responsible in constraint cylinder make differential pursuit relative motion with the angular velocity of cyclic fluctuation, keep one simultaneously
Individual angular velocity the most forward, meets electromotor without pause kinetic characteristic.
Due to the opposed installation of four-bar mechanism, at any one time, must be that a rocking bar relative main is instantaneous forward, another
Instantaneous backward, its absolute velocity is one speed of mainshaft of respective relative velocity superposition.If given little gear is relative to output shaft
The ratio of rotational velocity and output shaft rotating speedρ, in crank and rocker mechanism crank and rocking bar speed ratio extreme value [-m,n], then both are absolute
The relative size relation of value determines the differential pursuit characteristic of two rotors.Its rule is: if the relative rollback of instantaneous rocking bar backward
Speed maximum is more than the speed of mainshaft, then electromotor two rotor replaces rollback in the course of the work；If the phase of instantaneous rocking bar backward
To rollback speed maximum equal to the speed of mainshaft, then electromotor two rotor replaces instantaneous dwell in the course of the work；If instantaneous to
The relative rollback speed maximum of rear rocking bar is less than the speed of mainshaft, then electromotor two rotor is the most forward, tool
With or without pause characteristic.There is excessive sudden change of acceleration in first two forms of motion, and mechanism without pausing time, its acceleration change becomes
In mitigation, operating is more steady, and power performance is improved.In view of four-bar mechanism without the advantage of quickreturn characteristics, electromotor sets
It is long that meter must control bar, causes its speed ratio extreme value to regulate.
Therefore, effectively changed by two kinds of methodsρThe size of value, makes electromotor two rotor have without pause characteristic: (1)
Change gear ratio；(2) central gear or gear ring rotating speed are changed.Note that, for external toothing planet circular system, gear ratio is
It is negative,ρValue will with the reverse speed ratio ratio of extreme values of four-bar mechanism relatively, i.e. according to-mRegulateρ；For internal gearing structure, gear ratio is
Just,ρValue will with the forward speed ratio ratio of extreme values of four-bar mechanism relatively, i.e. basisnRegulateρ。
Rotation shell type of the present invention rotates pendulum engine without pausing, and uses above two method to use electromotor without pausing
While characteristic, owing to mechanism's entirety rotating speed improves, the fan-shaped stroke that the inlet and outlet of power cylinder are inswept is excessive, two sectors
Face no longer has obvious crossover location, and inlet and outlet mouth, lighting-up tuyere can not be fixed with the relative position of cylinder body.The present invention is to defeated
Shaft adds attached transmission mechanism, controls engine cylinder-body rotating speed with certain gear ratio, just offsets as realizing without resting
Characteristic and change the side effect that planetary gear construction is brought, each aperture position is fixed.
Inventive engine operation principle: after engine work, engine spindle uniform rotation, differential drives assembly
Retrain two rotors to pursue with the angular velocity differential of cyclic fluctuation, make each working chamber volume periodically increase, reduce；Premixed device
Thering is provided fuel source, fuel ignition in the most ignited working chamber for engine cylinder-body, gaseous-pressure promotes two turns
Son rotates acting, and under the constraint that differential drives assembly and mechanism loading, makes engine spindle uniform rotation, externally do work.
Can refer to reciprocating-piston engine be adjusted as the starting of electromotor, deceleration, accelerator, finally make electromotor normal
Work, i.e. reaches poised state.Herein as a example by each rotor is containing 2 vane-pistons, totally 4 working chambers in cylinder body, and start
