Description
Technical field
The utility model relates to engine structure, and particularly a kind of structure that adopts the motor of four fan-shaped gear-four tooth bar belongs to technical field of engines.
Background technique
Motor is the source of automobile power.Up to now, except electric vehicle few in number, motor car engine all is a heat energy power mechanism, is called for short hot machine.By the change of state of working medium, the heat energy that fuel combustion is produced is transformed into mechanical energy in hot machine.This motor is transformed into rotatablely moving of crank by connecting rod with the round straight line motion of piston, and then power is exported.In expansion stroke, the heat energy that motor produces fuel combustion is transformed into the mechanical energy that the promotion piston is done reciprocatory motion, drives bent axle by connecting rod again and rotates; In other strokes, come driven plunger reciprocating by crank again, thereby realize the process of ventilation and compression.
In the expansion stroke, the length of the acting arm of force L of piston action on crank changes along with the variation of crank angle θ.When piston during at top dead center, the center of piston, connecting rod and crankshaft main journal in line, at this moment the moment of torsion of bent axle is 0.The merit that gas pressure is done piston all is converted into " dead point " pressure to crankshaft main journal; And in other positions, the part of gas pressure makes piston produce lateral pressure, is exactly the pressure of countercylinder wall.This shows, conventional engines in the course of the work, the pressure that fuel combustion produces has only sub-fraction to be converted into the output torque of bent axle, and the overwhelming majority is converted into the pressure of piston countercylinder wall and to the pressure of crankshaft main journal, efficiency of energy utilization is not high.
In addition, in the work cycle of conventional engines, each parts institute bearing load all is periodically variable, makes to have produced uneven friction and bump (as engine knock, pull-cylinder phenomena) between each surface of contact, thereby influences the performance of motor.
The model utility content
The utility model purpose provide a kind of can overcome to the lateral pressure of " dead point " pressure of main shaft and countercylinder wall simple in structure, using scope wide, vertical four fan-shaped gear, the tooth bar motor of reliable operation, the opposed driving of four cylinders that energy utilization rate is high.
The purpose of this utility model is to realize like this, vertical four fan-shaped gear, the tooth bar motor, it is characterized in that being provided with, lower box, gear, tooth bar, transmission shaft, output shaft, on, lower box is fixedly connected, two ends are installed respectively and are connected cylinder head and cylinder head cover, on, be vertical two cylinders that are furnished with in the lower box respectively, a piston is housed respectively in each cylinder, two interior pistons of two pistons in the upper box and lower box are fixedly connected on the two ends of two-piston push rod respectively, in fixedly connected two toothed rack of each piston push rod both sides difference, the tooth bar of same piston push rod both sides is parallel to each other and flank of tooth piston push rod dorsad, between upper box and lower box, two transmission shafts and output shaft that is parallel to each other is installed respectively by bearing, two tooth sector and a driving gear are installed respectively on every transmission shaft with one heart, a driving gear is installed on output shaft with one heart, four tooth sector on two transmission shafts are meshed with four toothed rack on the two-piston push rod respectively, and the driving gear on two transmission shafts meshes with the output shaft upper transfer gear simultaneously.Be provided with the recirculated cooling water cover in the described upper and lower casing.
The utility model is rational in infrastructure simple, and usability is good, reduces idle work, improves the efficient of motor, energy saving.Mainly form by casing, cylinder head, four cylinders and four pistons thereof, two piston push rods, two transmission shafts, output shaft, four fan-shaped gear-four rackwork etc.Wherein, upper and lower casing promptly is a cylinder block, and cylinder head is used for sealing and the formation gas distribution system, thereby forms the firing chamber.Two of the upper-lower position correspondence pistons are connected to one by the corresponding piston push rod in the upper and lower casing, constitute two cylinder drive units, and therefore, upper and lower casing constitutes the four cylinder four-stroke device of motor; Be meshed with tooth sector on two transmission shafts simultaneously, give two transmission shafts transmission of power, being meshed with driving gear on the output shaft by the driving gear on the transmission shaft drives the output shaft rotation again.The utility model utilizes tooth sector-rackwork, and by mutual engagement, the oscillating rectilinear motion that steam-cylinder piston is driven tooth bar is transformed into a kind of reciprocating internal combustion engine that rotatablely moves of gear.
Working principle of the present utility model: the combustible gas blast produces huge positive pressure, the positive pressure that a certain cylinder produces passes to piston push rod by piston, order about tooth bar and do oscillating rectilinear motion, because four toothed rack are meshed with four tooth sector on two transmission shafts simultaneously, so just can pass to two transmission shafts to the positive pressure that blast produces by tooth sector-rackwork, driving output shaft by being meshed with driving gear on the output shaft again rotates, so whichsoever cylinder is in working stroke, all can finish by the conversion that rotatablely moves continuously of the oscillating rectilinear motion of tooth bar, and then drive output shaft and rotate continuously to two transmission shafts.
The concrete superiority of the utility model has:
1, is in plumbness in the course of the work all the time because of tooth bar and tooth sector,, overcome " dead point " pressure of main shaft and the lateral pressure of countercylinder wall so cylinder almost completely is delivered to output shaft to the thrust institute work that piston produces; Eliminated conventional engines in work cycle, each parts is because of cycle live load effect, makes inhomogeneous friction and bump (as engine knock, the scuffing of cylinder bore) phenomenon that produces between each surface of contact, thereby makes the efficient of motor reach maximum, and dynamic and static state performance is preferable.
2, adopt pinion and rack just to make in expansion stroke, mixed gas blast and the positive pressure that acts on piston head need not secondary and decompose, but the almost equivalent rack and-pinion mechanism that passes through drives the take-off (propeller) shaft rotation, reduce idle work, and then improve motor ground working efficiency, energy utilization rate height to greatest extent.
3, the water jacket of recirculated cooling water is set in upper and lower casing, upper and lower casing is effectively cooled off, prolong motor working life.Upper and lower casing is fixedly connected to form the machine oil fuel tank that closed space is an engine lubrication system.The outside at cylinder head is provided with cylinder head cover respectively, seals whole motor, is beneficial to dustproof.
