Description
Technical field
The utility model relates to a kind of motor, and the structure of particularly horizontal tooth sector tooth bar motor 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 purpose of this utility model is exactly at the available engine above shortcomings, provide a kind of can overcome to " dead point " pressure of main shaft and countercylinder wall lateral pressure simple in structure, using scope wide, reliable operation, horizontal tooth sector tooth bar motor that energy utilization rate is high.
The purpose of this utility model is to realize like this, horizontal tooth sector tooth bar motor, it is characterized in that being provided with upper box (upper cylinder body), lower box (lower cylinder body), cylinder head, take-off (propeller) shaft, tooth bar, tooth sector, driving gear, upper and lower casing and cylinder head are fixedly connected into closed space, be two cylinders of horizontal symmetrical distribution in the upper and lower casing respectively, a piston is housed respectively in each cylinder; Four pistons in the upper and lower casing are fixedly connected on the two ends of two-piston push rod respectively, the fixedly connected tooth bar of difference on the piston push rod, two toothed rack flank of tooth opposing parallel are arranged, between upper box and lower box, support two take-off (propeller) shafts that are parallel to each other respectively by bearing, two tooth sector and two intermeshing driving gears are installed respectively on two take-off (propeller) shafts, and two toothed rack mesh with two tooth sector respectively.
The two ends of described upper and lower casing are respectively equipped with cylinder head, and the outside of cylinder head is provided with cylinder head cover.Be provided with the water jacket of recirculated cooling water in the upper and lower casing.The closed space that upper and lower casing and cylinder head are fixedly connected into is the machine oil fuel tank of engine lubrication system.
The described setting angle that two tooth sector are installed respectively on two take-off (propeller) shafts differs 90 degree.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low.The closed space that upper and lower casing and cylinder head are fixedly connected into, as the machine oil fuel tank of engine lubrication system, cylinder head is used for sealing and the formation gas distribution system, thereby forms the firing chamber.Two pistons in the same casing are connected to one by the corresponding piston push rod, constitute two cylinder drive units, and upper and lower casing constitutes the four cylinder four-stroke device of motor; Be meshed with two tooth sector that are sandwiched between two tooth bars simultaneously, constitute double rack-bidentate wheel mechanism, drive two output shafts and do the gap rotation.The power of two tooth sector is exported to two driving gears of end respectively by each take-off (propeller) shaft, two driving gears are meshing with each other and constitute the output shaft linking mechanism.Utilize tooth sector-rackwork, by mutual engagement, the oscillating rectilinear motion that 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 two tooth bars are meshed with tooth sector on two take-off (propeller) shafts simultaneously, so just can pass to two take-off (propeller) shafts to the positive pressure of the generation of exploding by double rack-bidentate wheel mechanism.Because two take-off (propeller) shafts constitute the output shaft linking mechanism by the engagement of the identical driving gear of parameter, so whichsoever cylinder all can be finished by the conversion that rotatablely moves continuously to two take-off (propeller) shafts of the oscillating rectilinear motion of tooth bar in working stroke.
The two tooth bars while in the utility model is meshed with the tooth sector on two take-off (propeller) shafts, so just can pass to two take-off (propeller) shafts to the positive pressure that blast produces by double rack-bidentate wheel mechanism, make cylinder almost completely be delivered to output shaft, overcome " dead point " pressure of main shaft and the lateral pressure of countercylinder wall 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.Again because of adopting tooth sector, rackwork, 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 tooth bar-tooth sector driving mechanism that passes through drives the take-off (propeller) shaft rotation, reduce idle work, and then improve efficiency of engine, energy utilization rate height to greatest extent.The water jacket of recirculated cooling water is set in the upper and lower casing, can effectively controls excessive engine and heat up, cylinder head cover is set respectively, seal whole motor, be beneficial to dustproofly, prolong motor working life in the outside of cylinder head.
