Abstract
The utility model relates to an improvement of the internal combustion engine known by public, which replaces the crank link mechanism with a gear rack driving mechanism. The link is replaced by a rack engaged with the one-way driving gear on the main driving shaft, and thus the driving core part of the machine is formed; compared with the internal combustion engine in the prior art, the power of the utility model which adopts the driving mechanism can be increased by above one time; the mechanical load of primary members can be reduced, and the phenomenon of detonation can be avoided.
Description
The invention belongs to a kind of reciprocating piston type internal combustion motor.
The present invention is the improvement to known crankshaft connecting rod type explosive motor.Change straight line motion into the radial component that rotatablely moved with crankshaft ﹠ connecting, power-converting efficient is low.Under the situation that frictional force is ignored, power is decomposed power-converting efficient as can be known, the active force that piston produces bent axle through connecting rod to lower dead center from top dead center, can be decomposed into radial force and rotating force, producing radial force is idle work, and producing rotating force is useful work, according to the resolution of forces method as can be known, the size that produces rotating force equals the corner sine value that crank begins from top dead center, and can get its mean value as calculated is 0.635, and promptly average efficiency has only 63.5%.This is that the power with piston is uniform result calculated, in fact the active force of piston is uneven in whole stroke, reduce rapidly along with the increase of volume of cylinder, the mean effort of piston is 6-8 kilogram force/square centimeter, but the maximum outbreak pressure of fuel oil can reach 70-110 kilogram force/square centimeter, appearing at corner is that efficient has only 17.4 ' 21.5% near the 10-15, so efficient is far below 63.5%.
In view of the problem that above-mentioned prior art exists, the little high efficiency explosive motor of radial component when task of the present invention is a kind of power-converting of design, but functional reliability and be not less than the explosive motor of prior art working life simultaneously.
The present invention mainly adopts rack and pinion drive mechanism to replace crankshaft-linking rod drive mechanism, reduces radial component.As shown in drawings, piston (8) and tooth bar (6) join together, replace the bent axle of prior art with the main shaft (4) that unidirectional driving gear is housed.This device is in working stroke, and the tooth bar total amount is current along the gear tangent direction, and radial component is little from start to finish.
The connecting rod of connecting rod (7), crank (9) and crankshaft compositions such as (10) is finished other three strokes.One and tooth bar hinge of connecting rod, other end and crank hinge, crank and crankshaft are fastenedly connected, and crank and main shaft adopt gear transmission or sprocket wheel chain transmission in another transmission case.Gear on the crankshaft or sprocket wheel also are unidirectional, when the rotating speed of the rotating ratio main shaft of crankshaft is slow, is being driven and is rotating, and when faster than the rotating speed of main shaft, the rotation that can exceed the speed limit easily is in order to avoid produce mechanical contradiction.
Accompanying drawing is a no crankshaft reciprocating piston formula explosive motor structural representation of the present invention.
The structure of unidirectional drive sprocket comprises: gear ring (1), interior cover (2), roller (3), pressing spring (5) and ring washer (not drawing among the figure), gear ring and interior cover are slidingly matched, contact with gear ring in the special-shaped groove of cover in roller is contained in and small gap arranged, the bottom surface of this special-shaped groove be one from beginning to extend approaching with the gear ring inner circumferential surface gradually round slip surface to an end with the roller points of tangency, become the track of roller.Roller produces frictional force with gear ring and interior cover all the time under the effect of pressing spring, like this when gear ring with respect to interior cover when the track bearing of trend rotates, roller is being driven together and is being rolled, the gap dwindles gradually, pressure increases gradually, produce enough frictional force face transmitting torques, when gear ring rotated in the opposite direction, frictional force was dwindled gradually and can not transmitting torque.
The working procedure of this explosive motor is as follows: piston is subjected to the thrust of expanding gas and during moving linearly, the gear-wheel gear-ring rotation on the rack drives main shaft, and at this moment, ratchet can transmitting torque, and kinetic force is delivered on the main shaft.Tooth bar is through the do time spent of connecting rod to crank, and is faster than the speed that crankshaft is original, is delivered to crankshaft in main shaft power and has under the unidirectional situation, the rotation of crankshaft hypervelocity, the mechanical contradiction of unlikely generation.Piston stroke at the end, crank has become active force, forces tooth bar to rise, and finishes exhaust stroke, suction stroke and gas pressuring stroke all are that active force is finished with the crank.Just continuous operation again and again when the combustion condition of firing chamber is sufficient like this.
Accompanying drawing and the above are the embodiment of single cylinder four-journey, and such explosive motor needs main shaft to tell certain motivational drive crank rotation, just can reach the job requirement that goes round and begins again.If multi-cylinder internal combustion engine, the expansion space stroke of a cylinder can be finished another cylinder compression stroke, and connecting rod only plays position-limiting action, and structure has relatively been simplified.
Other structure of no crankshaft reciprocating piston formula explosive motor of the present invention, as distribution device, supply system, cooling system, starting arrangement and electrical equipment etc. all adopts the I. C. engine of prior art, has only the change of size.Adorn a bell-mouthed exciter as the bottom of tooth bar, when tooth bar rapid when descending, lubricant oil from horn mouth upwards spatter, each member of lubricated top.With the single cylinder is example, the gear-box of afterbody has three axles: main shaft (dress speed regulator and drive sprocket etc.), and crankshaft (adorning driven One-way chain wheel and driving gear etc.) and camshaft (general part), piston can be done shortly, the change of body shape and position, or the like.
This explosive motor is compared with the crank connecting link transmission reciprocating-piston explosive motor of prior art, and have following characteristics: power conversion efficient can improve more than 36.5%, and the efficient of the internal combustion engine of prior art is about 25-40%. So mechanism driving efficient can be enhanced about more than once. When producing maximum outbreak pressure, the speed that piston descends is fast, can reduce mechanism's load and the phenomenon of detonation of stressed parts, add no component, maximum explosive force all becomes useful work, and the power of output is big, no component, can adapt to low-speed running and over a long time overload operation, efficient is enhanced about more than once, and this just makes same big engine power double above.
Claims (2)
1, no crankshaft reciprocating piston formula explosive motor, comprise the piston (8), main shaft (4), the crankshaft (10) that do reciprocating linear motion, it is characterized in that piston (8) connects with tooth bar (6), unidirectional driving gear engagement on tooth bar and the main shaft (4), with connecting rod (7) hinge, connecting rod (7) is formed connecting rod with crank (9).
