Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of simple in structure, compact, reliable operation, the thermal efficiency high, discharge low, to adapt to the pluralities of fuels such as gas and oil, rock gas, oil gas at night, shale gas, coal-seam gas Spark ignition type three stroke garden disk rotor motors.
The invention provides a kind of three stroke garden disk rotor motors, it comprises cylinder body 1, garden disk rotor (outer Yuan Zhoushangyou working room pitting) 2, front cover 3, rear end cover 4, main shaft 5, central diaphragm 6, residual gas removing device 7, and the air inlet system and exhaust system of conventional engine (only part), fuel supply system, electronic control system (containing igniting subtense angle), rotor dynamic output mechanism is characterised in that: the torque that rotor is done garden Zhou Yundong generation is to be integrated (seeing Fig. 3) by main shaft 5 with rotor 2 is direct-connected, by main shaft output power, its association is positioned at by cylinder body 1, front cover 3, rear end cover 4, in the cavity volume that (as being that multi-cylinder engine also should install central diaphragm 6 additional between every two cylinders) formed (seeing Fig. 1), 1 of cylinder body is fixed on support (sees Fig. 2).
The invention provides a kind of three stroke garden disk rotor motors, the feature of its working principle is: form a work cycle by three strokes, that is: intake stroke 1., expansion space stroke 2., exhaust stroke 3., see Fig. 2.
Described cylinder body 1 (seeing Fig. 2 cylinder body 1), on the week of Qi Wai garden, be furnished with two suction ports, spark plug mouth, two waste gas rows mouthful.
Described cylinder body 1, rotor 2, front cover 3, rear end cover 4, central diaphragm 6, all belong in order to gain in strength, rigidity is beneficial to cooling and is distributed with the cavity body of stiffening rib.Wherein rotary piston inner chamber with oil pump through main shaft oil duct supplying machine oil be used as cooling, also do pressure lubrication for all seal rings of main bearing 5-1 and the outer garden of rotor simultaneously.Cylinder body 1, front cover 3, rear end cover 4, central diaphragm 6, etc. adopt recirculated cooling water mode cooling.
Described 2 Wai garden weeks of rotor, to meet Fig. 1, rotor 2 and the interior garden of cylinder body 1 contactless in the upper working room that forms one or more airtight slips by or N special type pitting and the interior garden of cylinder body 1 side face, remain setting gap, eliminated piston and the fricative heat of cylinder body and reduced the power consumable of motor.
Described three stroke rotary engine rotation power outputting mechanism, it is characterized in that: rotation power outputting mechanism is made up of with main shaft 5 is direct-connected rotary piston 2, see Fig. 3, main shaft 5 and rotor 2 form one in the assemblying body of cylinder body 1, front cover 3, rear end cover 4, see that Fig. 1, main shaft 5 are sleeved in main bearing 5-1, rubbing surface is implemented pressure lubrication.
Described three stroke rotary engine working principles are characterised in that: by intake stroke 1., expansion space stroke 2., exhaust stroke 3., form a work cycle, often a circled work cycle, working room of rotor 2 made a merit.The details of its work done are shown in Fig. 2: the air entering after stroke 1.-1, at this moment supercharging in the time that rotor 2 Wai Yuanzhoushang working rooms arrive A place is subject to ECU instruction directly to spray into working room, along with the B place rotating, working room arrives stroke 1.-2, at this moment according to ECU command fuel sparger pressure direct injection fuel to working room and on request, thereby completing stroke twice in-cylinder pressure 1. directly sprays, so far, the straight throw order of air inlet completes.Thereafter, working room goes to C place and enters stroke 2., make mixture combustion, expansion working according to ECU instruction high-energy sparking plug energising arcing, and its kinetic energy is directly exported by the main shaft 5 being integrally connected with rotor.While approaching cylinder body D place (stroke 3.-1) along with rotor, just start to scavenge fast, waste gas is got rid of substantially during by D place.The inhibition that can circulate to working room's combustion reaction at next for eliminating a small amount of residual gas, therefore turn round to cylinder body E place in working room, (be stroke 3.)-2 o'clock waste gas sweeping devices 7 just exclude residual gas automatically, and this is most important to improving natural gas engine performance.Like this, working rotor chamber has just completed a work cycle through B place, C place, D place, E place from cylinder body A place, that is: stroke 1. directly spray intake stroke 2., 3. exhaust stroke (referring to Fig. 2) of expansion working stroke.
So different from traditional combustion engine four-stroke Li Lun rotation: three stroke rotary engine reduce by a compression stroke theoretically, the in-cylinder direct injection technology that its skilful second land productivity is implemented with ECU (Electrical Control Unit) ECU, thereby the in-cylinder direct injection technology that namely Hyundai Motor generally adopts realizes working medium band straightening spirt gas, complete the compression essence of non-compression stroke.。
Three-stroke engine merges into one by air inlet and compression theoretically, directly working medium is sprayed into working room and has produced therefrom many substantive technological progresses:
1, cylinder body directly sprays fuel, air directly enter working room, its quality and density are much better than traditional machine and enter mode, working medium in cylinder by intake manifold and avoided the higher admission line of temperature and exempted thermal expansion and resistance, thereby charging efficiency significantly improves, the thermal efficiency is promoted, for example by jet in cylinder be also very effective to recovering natural gas engine power.
2, the machine is according to operating mode, by ECU dynamic adjustments sprays into working room in good time power pressure, quality, capable of dynamic adjust compression ratio (or pressure ratio), the power pressure, the quality that spray into working room by adjusting can obtain the required compression ratio of operating mode (as 10-15 or higher) thus really realize and softly adjustablely can realize Lean Burning Technique.
3, working medium high-voltage high-speed directly sprays in cylinder, can absorb heat in cylinder, reduce maximum combustion temperature, reduce the probability of improper burning, and its time is of short duration, thereby in cylinder, be extremely difficult for deflagration, so octane value is low and lead-free low trade mark gasoline also can safety, effective use, increased the selection to oil product kind.
4, when deflagration makes conventional gasoline engin mechanical wear than normal combustion large 27 times, cause that damage of components, engine life shorten, deflagration is the major obstacle that traditional igniting type engine performance further improves.The technology of the present invention makes deflagration become extremely difficult generation, has solved this difficult problem.
5, for using for CNG, three-stroke engine adopts cylinder inner high voltage spraying technique can reach higher fuel feed and the shorter air feed time for spraying of continuity, realized the matter that fuel supplies with completely and regulated.Therefore, CNG can just can enter cylinder by the large decompression of 20Mpa to 2-3kpa and use as conventionally, in fact CNG can be controlled to the high pressure of 12-16Mpa, just can realize the injection of cylinder inner high voltage gas, obtain the high thermal efficiency and effectively reduce fuel consumption, also can save the power consumption of polymer processing of many CNG.
6, for reducing NO
xdischarge, Hyundai Motor utilizes exhaust gas recirculation to reduce maximum combustion temperature in cylinder to reduce NO to reach
xdischarge.The technology of the present invention got rid of in compression stroke, cylinder mixed gas do not have compressed, in natural cylinder maximum combustion temperature lower than conventional engines, NO
xgrowing amount will be along with reducing, remove compression stroke and not only reduced as seen the power consumable of motor, to reducing NO
xdischarge also has extremely long-pending meaning.
7, improve in-cylinder combustion pressure, shortened combustion duration, combustion efficiency further improves.Data demonstration, spark-ignition engine, in the time that compression ratio brings up to 8 from 6, the theoretical circulation thermal efficiency can improve 10% left and right.And compression ratio (or pressure ratio) can change with working conditions change the three stroke rotary engine of (can reach 10-15) carry out the lean combustion thermal efficiency against higher compression ratio (pressure ratio) can be better.
8, explosive motor is more simply more reliable as dynamic power machine, its mechanism, and vitality is also stronger.Must be the most succinct rotor and output shaft the formed mechanism that is directly connected, three stroke rotary engine the simplest this motor (seeing Fig. 3) just.It substitutes the reciprocating piston of traditional machine, connecting rod with the rotor rotatablely moving, and very rational beyond doubt from mechanics, it has been got rid of bent axle, connecting rod, piston, gas and has cut down driving mechanism and supporting numerous pipelines.It does not have any high-speed motion component except rotor and main shaft, and bearing number is few, has therefore saved at work power consumable that traditional machine takies in a large number and really improved the thermal efficiency of motor.It does not have reciprocating mass, motor in any cylinder number can obtain complete equilibrium, in high load motion more reliably, more durable.Therefore, the quality of three stroke rotary engine and volume person can be declined to a great extent, and its quality, volume be not enough traditional machine 50% all.Its manufacturing process generalization, manufacture cost is only that traditional machine 30-50%, the applicable marketization are produced.
9, every piston of three stroke rotary engine circles and just makes a merit (as every piston has N working room, make merit N time), and conventional reciprocating machine crankshaft turns two weeks and only do one time merit, obviously, effective rotating speed and the power of three stroke rotary engine, much higher than traditional machine.The for example four cylinder engine of four-stroke type passenger car, in the time that per minute 5700 turn, power reaches 92kw but in the time that the condition such as swept volume of a single chamber and compression ratio is suitable, and a working room of three stroke rotary piston machine a slice rotors only per minute 3850 while turning, just can reach 92KW.During as a slice piston Shang Youliangge working room, as long as per minutely reach 1925 and just can obtain 92KW power while turning, during if any two or the work done of multi-disc rotor, that just can obtain higher effective rotating speed, larger useful horsepower.Visible, three stroke rotary engine are particularly suitable for to the internal-combustion engine future development of high-power, high rotating speed, high efficiency, low noise, low emission.
10, three stroke rotary engine, can realize high compression ratio, Lean Burning Technique and utmost point non-detonating, can be applicable to veritably various Spark ignition type fuel, both also suitable single-fuel of suitable dual-purpose fuel, was particularly suitable for rock gas, and liquid gas, shale gas, that coal-seam gas is made single-fuel is special.This novel machine not only compression ratio can improve, and in cylinder, charging efficiency can large panel height.The physicochemical characteristic of green energy resource rock gas, shale gas, coal-seam gas also can be not fully exerted, and burns complete, satisfactory for result.Originally the output power of natural gas engine does not reach the output power of gasoline engine, but the rock gas dedicated mode increasing for compression ratio, the thermal efficiency but improves approximately 9% than petrol engine, harmful matter CO discharge decline 20% above NO compared with petrol engine in rock gas tail gas
xdischarge decline 40-50%, NO
2reduce by 25% left and right.
11, when three stroke rotary engine are worked, Zhou Shang working room, rotor garden high-temperature fuel gas of burning expansion in work done is to be ejected into garden face in cylinder body along the tangent direction in garden week, and powerful reaction force obtains the torque of rotor to maximize, also can obtain the maximization of power stage with the main shaft of the direct-connected one of rotor simultaneously.
The technique effect that the present invention has is: the direct-connected one of garden of the present invention disk rotor and main shaft, composition power transmission mechanism, greatly simplified conventional engines power take-off mechanism, it got rid of bent axle, connecting rod, piston, valve actuation mechanism and supporting pipeline saved they be in operation a large amount of engine power consumables that take and the expensive real estate taking, effectively improved engine thermal efficiency.Therefore, three stroke rotary engine quality and volume reduce to not enough traditional machine 50% like a cork, and manufacture cost is only traditional machine 30-50%.
What when working rotor of the present invention, carry out is circular movement, and it does not have reciprocating mass, is exactly any cylinder while counting, and motor can obtain complete equilibrium.Between garden disc rotor and cylinder body, do not contact, remain the gap of design and implement engine oil pressure lubricated, eliminate friction and heating and owing to having removed numerous traditional machine high-speed motion component, as connecting rod, piston, distribution device etc., also just eliminated the main vibratory source of noise.Even such structure in high loaded process still more reliably, more durable, the therefore very small more environmental protection of the vibration of new work engine and noise, the long working life of motor.Due to significant improvement and the innovation of new structure, it does not have the distribution device of the such a set of complexity of reciprocating engine, do not need to adjust valve clearance and grind valve, between cylinder body and end cap, do not add head gasket, can be as reciprocating engine yet, time have a situation that washes out head gasket, owing to there is no to-and-fro motion, there is no piston rod, just there is no cylinder liner often by the phenomenon of " scuffing of cylinder bore ", therefore, maintenance load can greatly reduce, and becomes easily simple.
The present invention adopts cylinder inner high voltage to spray gas technology (domestic successful technology), can reach higher fuel feed and continuity shorter in the gas jet period, has realized the matter that fuel supplies with completely and has regulated.Therefore CNG can just can enter cylinder use to 2KPa-3Kpa by the large decompression of 20Mpa, and through technical finesse, can remain between 12-16Mpa and directly spray into firing chamber work, just can save thus the manufacture energy of the CNG of many preciousnesses.
The present invention is Spark ignition type three stroke garden disk rotor motors, and the compression stroke that it has got rid of quartastroke engine adopts the general ECU (Electrical Control Unit) (ECU) of Hyundai Motor and then realizes the two-in-one intake stroke of in-cylinder pressure direct injection fuel, air.Due to uncompressed stroke, and the in-cylinder pressure carrying out directly sprays, has substantially eliminated the generation of deflagration phenomenon, because the raising of this type machine compression ratio (or pressure ratio), the raising that can realize reliably the raising of lean burn technology, the fuel consumption that has reduced widely petrol engine, its volumetric efficiency and the ratio of compression make fuel economy improve 25% left and right, and greatly improved the exhaust emissions level of petrol engine, Economy and the power output of fuel all can be improved a lot.
The present invention's three stroke rotary engine, adopt ECU controlled medium directly to spray to in-cylinder pressure, and can in time regulate according to operating mode ECU (Electrical Control Unit) ECU the power pressure that sprays into working room, quality, and by regulating the quality of working medium, pressure, dynamically adjust compression ratio (or pressure ratio) really realize compression ratio (or pressure ratio) soft adjustable and can reach higher compression ratio (as 10-15 or more than), thereby improve maximum combustion pressure in cylinder, shorten the duration of burning, combustion efficiency will further improve that (for example compression ratio brings up to 8 from 6, the thermal efficiency of spark ignition flower motor theoretical circulation improves 10% left and right).
The present invention can improve compression ratio (or pressure ratio) can realize Lean Burning Technique make mixture combustion thoroughly, the fuel efficiency that is converted into kinetic energy improves, directly promoted the raising of engine power performance, given play to maximal efficiency, burning more completely, not only greatly reduces fuel consumption rate but also improved widely engine exhaust emission level while making work because lean combustion makes fuel oil.Claim according to data: higher more than 13% than regular gasoline machine by experimental verification is known, fuel jet type stratified charge engine uses fuel Economy, consider that smelting, total fractional energy savings reach 23%.Effect of the present invention can be better.Three structures of stroke rotary engine excellence and the working principle of science make motor have the fuel tolerance of broad-spectrum, not only liquid gasoline etc. is suitable for, many combustion gas also can be used, and particularly the gaseous fuel such as rock gas, shale gas, liquid gas, coal-seam gas all can become the energy.Mostly they were that the good physicochemical characteristic such as rock gas did not obtain performance, even power decline in addition with the shared duel fuel engine of petrol engine but because compression ratio is low in the past.The present invention, can be increased substantially volumetric efficiency, can be recovered natural gas engine power by gas jet technique in cylinder, and the technology of the present invention can improve compression ratio, and this is also power character, the most effective a kind of means of the raising thermal efficiency of recovering gas car engine.The rock gas dedicated mode, the thermal efficiency that increase for compression ratio but improve 9% than petrol engine.In rock gas tail gas harmful matter CO discharge compared with petrol engine decline more than 20%, NO
xdischarge decline 40-50%, CO
2reduce by 25% left and right.
Special construction and the working principle of the present invention's three stroke rotary engine, determined its effective high rotating speed, high-power and efficient output characteristics.For example: certain passenger car, be four-stroke 4 cylinder machines in upright arrangement, discharge capacity 1.781L, when its rotating speed per minute reaches 5700 while turning, power reach 92KW, but, as in the time that swept volume of a single chamber and compression ratio (or pressure ratio) etc. are suitable with it, the only epitrochanterian working room of a slice and as long as per minutely reach 2850 while turning, power just can reach 92KW of three stroke rotary piston machines.During as a slice rotor Shang Youliangge working room, only want in theory 1425 power that just can obtain 92KW while turning that reach per minute, in the time having the multiple working room of multi-disc rotor, that just can easily obtain more effective high rotating speed, larger power, its instantaneous acceleration is fine, can suitable racing car or specific use, in addition motor of the present invention has higher compression ratio (or pressure ratio) and succinct, reliably, small and exquisite, quiet power mechanism, reasonably working principle, just can obtain in sum high power per liter, lower specific fuel consumption, weight/power ratio, can obtain high effective efficiency, the durable life-span, produce low row, micro-shaking, the environment protection effect of low noise.
Three stroke garden disc rotor motors, by the performance with good, cheap cost, compared with the broad-spectrum applicability of the versatility of low operating cost, manufacturing process, fuel, the feature of environmental protection and become the power source of new generation that integrates four stroke engine, rotary engine advantage reliably, are widely used in automobile, boats and ships, aircraft, railway locomotive, engineering machinery etc. field.
Be elaborated below in conjunction with drawings and Examples
As shown in Figure 1, three stroke rotary engine main parts assemble positive facade view, as shown in the figure, comprise: cylinder body 1, rotor 2, front cover 3, rear end cover 4, main shaft 5, and main shaft 5 passes cylinder body 1, rotor 2, front cover 3, rear end cover 4, occupy center, main shaft 5 is connected at keyway place by key 5-2 with rotor 2, and when work, main shaft rotates with rotor synchronous.Front cover 3 and rear end cover 4, cylinder body 1 all with bolt connect bolt hole on garden week separately link, fixing, the water cavity in these bolts hole and cylinder body, end cap is obstructed, gets rusty in order to avoid bolt soaks.Each parts relative position and installation precision shown in Fig. 1, determine (seeing Fig. 2) by Xiao hole, upper accurately machined two location of the week of garden separately.Between cylinder body and end cap, also should ensure due sealing, therefore, machining accuracy and the degree of finish of cylinder body 1 end face are had relatively high expectations, also there are certain requirements for the impacting force on mating face simultaneously, in order to solve reliably water shutoff, envelope gas problem, can on the end face of the inside and outside wall of cylinder body, be processed with the annular groove of sealing, be embedded in " O " shape heat resistant rubber circle at groove.When work, cylinder body 1 inwall and working rotor chamber 2-1 are around in high-temperature area, cooling action is very important, outside cooling apart from cooling water, oil circulation, inboard wall of cylinder block C → E section (seeing Fig. 2) is answered attenuate, working rotor chamber 2-1 around also suitably attenuate (must proof strength and rigidity) thin-walled be beneficial to heat transfer, Maximum operating temperature and the temperature difference be can reduce, local superheating and distortion avoided.
Shown in Fig. 1: power stage main shaft 5 is the core body of high engine speeds motion with the direct-connected one of rotor 2, for guarantee high speed, steady, durable operation, must be at the central hole location of front cover 3 and rear end cover 4, install by each 1 of the main bearing 5-1 of design apolegamy, main shaft 5 is connected to main bearing location.Each main bearing adopts engine oil pressure lubricated.
Figure 3 shows that three stroke rotary engine power stage mechanisms, rotor 2 combines schematic diagram with main shaft 5, and Fig. 3 B is front section view, and Fig. 3 a is side elevation sectional view, and rotor 2 connects and is connected with power stage main shaft 5, and is located at keyway by key 5-2 at knot position.Rotor has (or N) the pit 2-1 of working room on 2 Wai garden weeks, this pit is in-cylinder pressure direct injection fuel, the venue of air, also be igniting, burning, expand and produce the position of power, the geometrical shape of working room and moulding should be able to make working medium atomization splendid, and burning is desirable, and make all garden tangent direction ejections outside rotor of high-temperature fuel gas, the reaction force (torque) of forceful action on inboard wall of cylinder block face maximized.
Shown in Fig. 3 b: main shaft 5 is the maximum parts of being loaded in motor, and the size of these loads also changes, therefore, main shaft not only will have higher strength and stiffness, also will have good fatigue resistance.And in twin-tub machine, can still adopt two supporting spindles, and span is larger therebetween, and the rigidity of main shaft is poor, so in the middle transition section that designs twin-tub owner axle journal, should suitably strengthen changeover portion size, to ensure that main shaft has enough rigidity.
Figure 2 shows that the part (mechanism) that three stroke rotary engine power produce, that is: cylinder body 1, the positive facade view of rotor 2 and main shaft 5 assemblying bodys, forming one (or multiple) by all cambered surfaces of the pitting 2-1 on 2 outer garden weeks of rotor and the interior garden of cylinder body 1 slides, the 2-1 of working room of sealing, in the time of work, tangentially spray high-temperature fuel gas, reflect through the interior garden of cylinder body 1 cambered surface, drive rotor 2 rotates and obtains the needed torque power of motor, then via outputing power with the direct-connected main shaft 5 of rotor 2.Described three stroke rotary engine working principles are characterised in that: by intake stroke 1., expansion space stroke 2., 3. exhaust stroke form a work cycle, rotor 2 work cycle that often circled, the 2-1 of working room makes a merit.The details of its work done as shown in Figure 2, that is: in the time that the outer garden of piston 2 2-1 of Zhou Shang working room arrives A place, enter stroke 1.-1, at this moment by electric control element ECU instruction, the air after supercharging just directly sprays into the 2-1 of working room, along with rotation, working room arrives the B place of stroke 1.-2, at this moment according to ECU instruction, fuel injector, to the 2-1 of working room direct injection fuel with pressure, directly sprays thereby complete stroke twice in-cylinder pressure 1..Gas in the jar straight spray has realized the matter that fuel supplies with completely and has regulated, air charge is not affected completely, thereby intake stroke at twice air inlet be easy to stratified mixture combustion, better effects if.Subsequent working chamber 2-1 goes to C place, enters stroke 2., and according to ECU instruction, spark plug (1-2) energising arcing makes the 2-1 of working room mixture combustion, expansion, work done, and its kinetic energy is directly exported by the main shaft 5 being connected with rotor 2.Thereafter, when 2-1 rotation in working rotor chamber approaches D place (being stroke 3.-1 place), just start to scavenge fast, during by D place, waste gas is got rid of substantially.For a small amount of residual gas in the elimination 2-1 of working room is by the inhibition circulating to the 2-1 of working room combustion reaction at the next one, in the time that the 2-1 of working room moves to cylinder body E place (being stroke 3.-2 places), the residual gas device 7 of the machine will be removed residual gas automatically.Like this, working rotor chamber 2-1, from A place, has just completed a work cycle through B, C, D, E place.That is: 1. directly spray intake stroke; 2. expansion space stroke; 3. exhaust stroke (work cycle in detail as shown in Figure 2).
Shown in Fig. 2: cylinder body 1 is combined into rotor 2 2-1 of working room that slides and seal, for ensureing working room's sealability, prevent that Leakage Gas, Vent from pressing, should around the 2-1 of working room, settle 2 profiled seal rings, against centrifugal force, all the time pasting the motion of the interior garden of cylinder body 1 cambered surface and lubricated by engine oil pressure, due to potted line very short (working room's length of sealing line only with the potted line appearance of a cylinder of conventional engines when), therefore, satisfactory for result.When work a large amount of high-temperature fuel gas can make cylinder body 1, piston 2 temperature rises too high, use for reducing working deformation impact, must be cooling in time, for the strength and stiffness of reinforcing member, improve radiating effect, cylinder body 1 should make be furnished with the hollow article of stiffening rib and with water pump circulating water it, and keep chilling temperature by technological requirement.When working rotor in high temperature, particularly when work done, the 2-1 of working room and around near zone be high temperature concentration zones especially, more should strengthen cooling, cooling, except making the cavity body of stiffening rib in structure, also cooling liquid (water) should be changed into the good machine oil of effect, with oil pump, through main shaft oil duct, pump oil enters rotor cavity and carries out cooling.
For improving engine thermal efficiency, physical dimension, the appearance of working rotor chamber 2-1, should be able to make all garden tangent direction discharges outside rotor of high-temperature fuel gas, to obtain the reaction force of cambered surface maximum in garden in cylinder body, thereby make the torque of rotor realize the maximization of maximization and main shaft output function.
Shown in Fig. 4, it is end cap of the present invention (forward and backward) schematic diagram
(the referring to single cylinder engine) that the inner chamber of three stroke garden disk rotor motors is made up of the end cap of cylinder body 1 and both sides.Twin-tub machine or multi-cylinder pusher side are made up of end cap and central diaphragm folder cylinder body.Because interior cavity temperature is higher, particularly 2-1 ignition district, working rotor chamber temperature is high especially, therefore, not only aspect material selection and design of Cooling System, should reduce the maximum temperature of casing wall as far as possible and dwindle the temperature difference of casing wall between everywhere, in design, also should ensure that cylinder body and end cap have enough strength and stiffness, the distortion when reducing work, improves the sealability of motor.Simultaneously, the bearing of the main bearing 5-1 of end cap or High Rotation Speed and power stage main shaft 5, important role, so the strength and stiffness of end cap 3,4 seem very important, the fastness that main bearing 5-1 and main shaft 5 form adopts from the engine oil pressure of main shaft oil duct and lubricates with guarantee and run up.End cap 3,4 be provided with location Xiao hole same with cylinder body 1, as the positioning datum of processing and assembling, whole motor is fixed on support.
