The utility model relates to a kind of motor, particularly be a kind of in the ring-type rotary piston explosive motor.
Interior ring-type rotary piston engine, still the category that belongs to internal combustion power mechanism, be applicable to every field such as automobile, motorcycle, internal combustion locomotive, aviation, boats and ships and combustion power generating, because simple in structure, volume is little, in light weight, power is big, efficient is high, pollutions is little, being used as power such as automobile, motorcycle, aviation, boats and ships has special meaning.
Rotary engine concerning conventional reciprocating formula piston engine, almost is technical revolution.No matter from structural principle, or thermal efficiency aspect, great breakthrough is all arranged.Here be briefly described nineteen fifty-five West Germany's wankel company proposition and (generally be called wankel rotary engine or triangle rotary engine in China's nineteen fifty-nine scientific research climax by the outstanding wheel of universally acknowledged length spoke bank face triangle rotary engine, in order to narrate conveniently, to call the wankel rotary engine in the following text), its structural principle is as shown in Figure 3.When engine start, if main shaft 21 rotates along direction shown in the arrow, the external gear 22 that is installed on the main shaft 21 also rotates along same direction with main shaft 11, is contained in main shaft 21 (throw of eccentric
Oo1=e part) the cambered surface triangle piston 23 on the eccentric shaft is being with around the O axle by main shaft 21 and is being revolved round the sun.But be fixed on the cambered surface triangle piston, with O
1Be the internal gear 24 of axis, because of with external gear 22 in engagement, so be with along same direction rotation by gear 22.Thereupon, cambered surface triangle piston is also around O
1The axis rotation.Theoretical calculation proves, as two gear velocity ratio i=z
3: z
5=2: 3 o'clock, if selected initial position condition as Fig. 3, the track that three summits of cambered surface triangle piston are walked was the outstanding wheel of a length width of cloth line shown in Figure 3, and three summits are nonslipping rollings on the outstanding wheel of length spoke line.If load onto at one of its recess and to cut tool, can process correct cambered surface triangle piston 23.Because cambered surface triangle piston is positioned at the outstanding wheel of length width of cloth line middle part, so two parts about the outstanding wheel of length width of cloth line is divided into form air-breathing, compression and burning expansion, exhaust work chamber respectively.Cambered surface triangle piston system shown in Figure 3 is in burning expansion, exhaust, air-breathing, compression end, enters the state of next work cycle, so four processes are finished simultaneously.Allow axle rotate a circle, cambered surface triangle piston is wanted work done three times, finishes three work cycle, is equivalent to three of air displacement four-stroke conventional engines.And inlet and outlet freedom unimpeded (resistance is very little), there are not bent axle, connecting rod and cam mechanism, demonstrate incomparable advantage, still, the development test since half a century proves that this structural principle exists the technical problem that is difficult to overcome.
1. as can be seen from Figure 3; in order to form this special track of the outstanding wheel of length spoke line; the cambered surface triangle piston of working under High Temperature High Pressure must be made complicated high-speed motion; extremely difficulty is carried out liquid lubrication; cause attached side sealing element 25 thereon with producing violent vibration in the 27 cylinder wall sliding frictions of the outstanding wheel of length spoke line cylinder; cause the seal element that machinery, physical property frequency domain lost efficacy under the High Temperature High Pressure; lost efficacy rapidly or damage; having lost to have sealability, even the scratch casing wall causes shutdown.Radial seal element 26 though be nonslipping rolling with casing wall theoretically, only is to seal by a Line of contact, so sealing effect also is difficult to guarantee.Add factor affecting such as foozle, running vibration, High Temperature High Pressure, sealing effect is just poorer.
2., single stage compression is than little, only suitable Spark ignition type is gasoline, natural gas engine, for requiring the bigger compression ignition engine of compression ratio, as diesel engine etc., then need carry out the secondary compression, make machine construction become very complicated, lose the due advantage of rotary engine.
In view of above reason, the purpose of this utility model be for provide a kind of simple in structure, volume is little, in light weight, power is big, the thermal efficiency is high, the interior ring-type rotary piston explosive motor of long service life.
