Description

A kind of piston engine
Technical field
The present invention relates to a kind of improvement of power engine.
Background technique
In existing piston engine such as the internal-combustion engine, what the straight line motion of cylinder piston was converted to that circumference rotatablely moves that output adopts all is that connecting rod-crank mechanism is realized, promptly piston-the connecting rod in the internal-combustion engine-crankshaft structure is realized.In connecting rod-bent axle transmission, the transmission arm of force is connecting rod and the tangent position of crankshaft rotating circumference to the maximum, minimum is that the connecting rod elongation line is through crankshaft rotating circle center position, and this moment, the arm of force was zero, because the arm of force constantly changes, therefore the efficient of conversion is extremely low, and this also is to hinder the bottleneck that power engine further improves energy utilization rate.In this simultaneously, because the bent axle form that adopts, its volume is also bigger, has also limited freely designing of piston stroke and cylinder size simultaneously, and this is the major reason that hinders the development of high efficiency piston engine.
Summary of the invention
Technical problem to be solved by this invention is to overcome the prior art deficiency, provides a kind of volume little, piston engine efficiently.
For solving the problems of the technologies described above, the present invention realizes by the following technical solutions:
A kind of piston engine, comprise the power engine cylinder body and be installed on the interior piston assembly of cylinder body, described piston assembly comprises the piston that is positioned at two ends symmetry installation, piston is fixed in the connecting rod two ends, connecting rod be provided with the tooth bar arranged along the piston motion direction and with the tooth bar meshed gears, gear is fixed on the powered maneuver power output shaft by unilateral bearing.
As improvement to such scheme, described tooth bar and gear comprise two pairs at least, two tooth bars are arranged in parallel up and down, and two tooth bars are dislocatedly distributed on vertical plane, two gears between two tooth bars and concentric install, two gears mesh with two tooth bars respectively, and two unilateral bearings of fixing two gears are equidirectional locked.
As further improvement of these options, firing chamber for realizing the continuous burning mode of work-doing between piston and cylinder body interior edge face, be provided with inlet hole, exhaust port and oil inlet hole at the firing chamber inwall, between piston assembly and cylinder body, be provided with and prevent that piston assembly from moving off-limits positioning component.Described positioning component comprises location card and two position-sensing switches that are arranged on the cylinder body that are arranged on the piston assembly, and two position-sensing switches distance is consistent with the piston assembly stroke.
Another improvement as to such scheme for holding the receiving cavity of pressurized gas or high-pressure water flow, is provided with import, outlet at the receiving cavity inwall between piston and cylinder body interior edge face, be provided with brake assemblies at the connecting rod two ends towards the gear direction.Described brake assemblies comprises an arc brake sheet, brake block is corresponding with step circumferential surface on being arranged at gear, the arc brake sheet is installed on the cylinder body by the spring that movable axis and driving brake block restPose, and two ends are equipped with the push rod that is used for brake block is pushed to the gear direction in connecting rod.
Relative prior art, the present invention has following advantage:
1. energy utilization rate increases substantially: when existing connecting rod-crankshaft structure moves, when connecting rod and bent axle tie point move to the position, point of contact of bent axle motion circumference, its conversion efficiency the highest (can be considered 100%), when connecting rod and bent axle tie point move to the connecting rod elongation line through bent axle motion circumference home position, its conversion ratio is zero (being referred to as the dead point), rotate in all processes at bent axle, connecting rod and bent axle tie point are through two dead points and two point of contacts, conversion ratio average in this process is no more than 50%, this shows that its energy utilization rate is lower than 50%; Structure of the present invention then is equivalent to connecting rod and acts on all the time on the bent axle point of contact, and conversion efficiency is in high state (can be considered 100%) always, this shows, compares less than 50% energy utilization rate with existing connecting rod-crankshaft structure form to be more than doubled.
2. volume of cylinder density increases substantially: the volume of cylinder density of power engine is meant the maximum cylinder volume of per unit volume or gravity power machine, existing connecting rod-bent axle power engine cylinder length and diameter are subjected to the restriction of bent axle diameter and compression ratio, cylinder can only be arranged by one pole, connecting rod-crankshaft structure and motion thereof occupy a large amount of spatial volumes, and in order to overcome bent axle when motion vibration essential factors such as other balanced designs, this class power engine can only have very little volume of cylinder; And the present invention can adopt the multi cylinder arrangement mode of parallel opposed, each cylinder is arranged compact more, the diameter of cylinder and length can freely design, the motion of connecting rod is finished in cylinder, the required space of connecting rod, gear is little, and need not too much balanced design, volume of cylinder density can reach more than the several times of existing power engine volume of cylinder density.And the volume of whole power engine can be done forr a short time.
3. increased substantially the working efficiency of cylinder: power engine of the present invention takes two stroke operation scheme and working stroke to take the mode of operation of continuous oil supply air feed sustained combustion acting, so can increase substantially the working efficiency of cylinder.
4. increase substantially the specific power of power engine: the specific power of power engine is the peak output of per unit volume or gravity power machine, be directly proportional with power engine energy transition rate, volume of cylinder density, cylinder operation efficient etc., by above-mentioned Several Analysis as can be known, the energy transition rate of power engine of the present invention, volume of cylinder density, cylinder operation efficient all are improved largely, so, its specific power also increases substantially thereupon, can reach ten times even tens of times more than that have power engine now, can be suitable with the specific power of turbo-power machine.
5. be convenient to build power engine from miniature to superhuge: the power machine structure of the present invention's design has been eliminated the disadvantage that existing power engine connecting rod-crankshaft structure exists, has high energy transition rate, cylinder operation efficient, volume of cylinder density, the length of specific power and cylinder and diameter are selected and can freely be designed as required, and can be designed as the multicylinder cngime of two cylinder power engines or even number, therefore, can design easily, produce various sizes, different capacity, satisfy the power engine that various situations require, comprise the internal combustion type power engine, waterpower formula power engine and steam power machine etc. are such as big power station, large-scale means of transportation, the power engine of high-performance micro aircraft etc.
