Description

A kind of piston-type direct-drive engine and design method for first taking force and then integrating

Technical field

The present invention relates to a kind of piston direct-drive motor, specifically a kind of piston-type direct-drive engine and design method for first taking force and then integrating.

Background technique

The directly driving type motor is existing public reported, for example " novel piston motor, the patent No. 01120523.7 " in patent documentation; " one-stroke to quick-fried free-piston engine, the patent No. 94238030.4 " " non-link rod reciprocating piston engine capable of changing output speed, patent No. 200510096455.9 ".The disclosed technology of above-mentioned document all is an opposed pistons directly driving type motor; The key problem of being discussed all is a how power taking problem; For example the patent No. 01120523.7 " adopt the ratchet of two band ratchets and the power of a sense of rotation of two-sided tooth bar engagement output that is connected piston; and the piston engine of " patent No. 94238030.4 " is that employing half wheel and rack meshes and carries out power taking; The patent No. 200510096455.9 " be power through planetary pinion taking-up reciprocating motion of the pistons; but the power of the unified direction rotation of taking out by the way can externally be done work; but but can not motor under static state be started through the external force reverse direction actuation, that is to say and can't let the initial suction of piston working in reciprocating mode realization press four strokes of quick-fried row again through external force.Do not have initial startup, motor just can't be worked, and also just can not realize the output of above-mentioned power.In addition; The big load that the work of motor is continuous often; It all is unpractical using ratchet and planetary pinion and the direct engagement of tooth bar, planetary pinion mode especially, and the diameter of piston has determined planetary space; Determined that also gear shaft can not have bigger intensity, tiny part has determined motor than short working life.

Embodiment

Explanation at length below with reference to Figure of description motor of the present invention being done.

Piston-type direct-drive engine of the present invention; Its structure is made up of motor body 1, cylinder barrel 2, piston 3, two-sided tooth bar 4, upper transfer gear 5, lower transmissioning gear 7, last transmission shaft 6, lower drive shaft 8 and power integrated mechanism; Wherein, Cylinder barrel 2 is symmetricly set among the motor body 1; Piston 3 is positioned among the cylinder barrel 2 and is connected the two ends of two-sided tooth bar 4; The both sides up and down of two-sided tooth bar 4 are provided with up and down two

transmission shafts

6,8 respectively, upper transfer gear 5 and lower transmissioning gear 7 be separately positioned on up and down on two

transmission shafts

6,8 and with the tooth bar engagement of the upper and lower surface of two-sided tooth bar 4, two

transmission shafts

6,8 stretch out motor body 1 and are connected with the power integrated mechanism up and down;

Being arranged on up and down, two transmission shaft end power integrated mechanisms have connecting bar and crankshaft formula structure and ratchet formula power integrated morphology:

Wherein connecting bar and crankshaft formula power integrated morphology is made up of eccentric wheel 9, connecting rod 10 and bent axle 11, and eccentric wheel 9 is separately positioned on the end of two

transmission shafts

6,8 up and down, and the two ends of connecting rod 10 connect eccentric wheel 9 and bent axle 11.

Ratchet formula power integrated morphology is made up of left-hand rotation ratchet 16, right-hand rotation ratchet 15, tumbler gear 14, the integrated gear 12 of power and pto 13; Left-hand rotation ratchet 16 and right-hand rotation ratchet 15 are separately positioned on the end of

lower drive shaft

6,8; Left-hand rotation ratchet 16 and integrated gear 12 engagements of power; Right-hand rotation ratchet 15 is through integrated gear 12 engagements of tumbler gear 14 and power, and the integrated gear 12 of power is fixing with pto 13.

Because the power integrated mechanism is arranged on the outside of motor body, mechanical strength and size do not receive the restriction of cylinder bore, so can guarantee the working life of motor and be convenient for changing maintenance.

Embodiment 1: in design of the present invention, the quantity of each face tooth is more than or equal to the quantity of last

lower transmissioning gear

5,7 on the two-sided tooth bar, and two-sided tooth bar 4 round trips can drive 5,7 positive and negative two weeks of rotation of lower transmissioning gear simultaneously.

If adopt arc length tooth sector suitable 17 and the starter receiver 18 that is arranged on transmission shaft 6 or the lower drive shaft 8 to mesh the startup that is used for motor with piston compression stroke; As shown in Figure 2; The number of teeth of two-sided tooth bar 4 can be greater than the gear of upper transfer gear 5 and lower transmissioning gear 7; Just two-sided tooth bar 4 round trips can drive

lower transmissioning gear

5,7 and rotate more than two weeks; If press the frequency of okperation of conventional engines piston, motor output revolutions of the present invention can improve more than 1 times at least, and power can increase more than 1 times at least.

Through above analysis, motor of the present invention can design piston has bigger stroke, can obtain bigger compression ratio in other words, and this is very tangible to the oil-saving effect that improves motor, and especially DENG is made compressor and used all the more so.

When crankshaft connecting rod type power integrated mechanism and ratchet formula power integrated mechanism were used for engine design, crankshaft connecting rod type power integrated mechanism was used for the startup or the power output of motor, and ratchet formula power integrated mechanism is used for power output.

Embodiment 2:

At the calculating compression ratio with on firing time; Two-sided tooth bar directly driving type structure of the present invention also than traditional crankshaft connecting rod type structure come simple and convenient; Because the stroke of piston is exactly the displacement distance of tooth bar; The displacement distance of tooth bar is directly measured through the clockwise and anticlockwise of transmission shaft, people can be selected survey best firing time or compression ratio, obtains the output of maximum oil-saving effect and power.

Cylinder for double being oppositely arranged, middlely connects through gear-box in motor body, divides the processing of three parts like this, and it is quite simple that technology just becomes, for assembling and maintenance provide convenience.

The ignition system of motor of the present invention, air inlet system and exhaust system, cooling system and lubrication system are identical with conventional engines, are known technology, can transplant direct application, therefore no longer repeat in this literary composition.
