Rotor linking mechanism 10 is provided with between acting unit group 12 on two line shafts 4, the position being positioned at the axle sleeve 15 of homonymy acting unit A end on two line shafts 4 (only arranges axle sleeve 15 and linking mechanism 10 in the side of acting unit group here, certainly in the both sides of acting unit group 12, can said mechanism be set), the structure of rotor linking mechanism 10 comprises: interlock driving gear 28, interlock driving gear 29, interlock driven gear 30 and interlock driven gear 31, interlock driving gear 28 and interlock driving gear 29 are separately fixed on every root line shaft and do work on the axle sleeve 15 of unit A end, the outer wall of the cylinder body 1 of unit group 12 that every root line shaft 4 does work is fixed with gear shaft 32, gear shaft 32 is provided with bearing, interlock driven gear 30 and interlock driven gear 31 are arranged on two bearings respectively, interlock driving gear 28 passes through gears meshing with close interlock driven gear 30, interlock driving gear 28 with away from interlock driven gear 31 pass through belt transmission, interlock driving gear 29 and close interlock driven gear 31 by gears meshing, interlock driving gear 29 with away from interlock driven gear 30 pass through belt transmission.The object done so is also the direction of rotation in order to be made the rotor on two line shafts by linking mechanism.
The reciprocating rotary piston engine that section Example of the present invention provides, its rotor 2 and line shaft 4 coaxial rotation, can coaxial transmission output shaft 11, and its weight of rotor 2 distributing equilibrium diametrically of screw shaped, the operation process of rotor 2 produces vibrations hardly, and engine running is steady.Secondly, rotor 2 is coaxial with rotor 2 with the surface of contact of cylinder body 1, so to the abrasion equilibration of cylinder body 1 when rotor 2 rotates.
We know, gas pressure suffered by object equals the product of gas pressure intensity and object receiving force area, when the pressure of expanding gas is constant, the lifting surface area increasing acting parts can increase that it is stressed, in addition, the tangential force that moment of torsion equals axle is rotated and this power, to the product of axis of spindle distance, increase this power can increase rotation moment of torsion to the distance of rotating shaft center line when tangential force is identical.The energy produced to make fuel combustion obtains cascade utilization, in the process that expanding gas pressure reduces gradually, can by increasing the lifting surface area of acting parts (i.e. rotor 2) by expanding gas pressure gradually, and the distance that increase is ordered about between the tangential force of axis of rotation and rotating shaft (i.e. line shaft 4) center line is to obtain enough moments of torsion, enable to produce enough large moment of torsion acting compared with the gas of low pressure, thus improve the utilization ratio of fuel.Represent with mathematical formulae: in N=FL=kPSL formula, N is moment of torsion, F is that expanding gas acts on the tangential force that rotor 2 is rotated that rotor 2 produces, and L is the distance that tangential force arrives rotor 2 axis, and k is constant, P is the pressure of expanding gas, and S is effective lifting surface area that rotor is subject to expanding gas.As can be seen from above-mentioned formula, because the long-pending of SL constantly increases, so N linearly can not reduce along with the reduction of P, when the value of the minimal torque N driving line shaft 4 to rotate is constant, the minimum value of P can be very little, namely drain pressure can be very little, so just reaches the object reducing drain pressure, achieve the cascade utilization to combustion gas energy.
Its air work unit of the reciprocating rotary piston engine that section Example of the present invention provides comprises the rotor 2 and cylinder body 1 supporting with it and sliding plug 5 that main body is conical screw shape, the worm tooth 16 of rotor 2 main body seals with cylinder body 1 wall and contacts, and rotor 2 can rotate freely in the die cavity that cylinder body 1 internal face surrounds around own axes, the A end of acting unit is communicated with expanding gas.Such structure makes expanding gas threadingly to expand by groove 17, and the cell wall due to thread groove 17 is an inclined-plane, and expanding gas acts on thread groove 17 will produce a tangential force that rotor 2 is rotated about axis.In thread groove 17, storing sliding plug 5 plays and stops that expanding gas passes through and impels it to act on the effect that rotor 2 drives rotor 2 to do work.Cylinder body 1 arranges the chute 7 of a longitudinal direction, and make sliding plug 5 threadingly groove 17 and chute 7 slide, sliding plug 5 can be made when rotor 2 does not move axially by the rotation of the rotor 2 that is slidably matched.Sliding plug 5 is designed to two boards shape thing crossing decussate texture perpendicular to one another, its outer rim is contacted with thread groove 17 cell wall, bottom land, cylinder body 1 inwall and chute 7 inner wall sealing, being intercepted by the passage that cylinder body 1 inwall and thread groove 17 are formed is four regions, two regions at diagonal angle communicate between two, and four the effective lifting surface areas of part making sliding plug 5 form two zone boundaries that communicate are equal.This structure makes two region internal air pressures at sliding plug 5 diagonal angle equal, the pressure energy of expanding gas acts on sliding plug 5 simultaneously and forms in four parts of these two zone boundaries, make sliding plug 5 contrary by expanding gas pressure equal and opposite in direction, direction, offset each other, thus make sliding plug 5 stress balance generally, not because producing extra frictional force by expansive force and acting unit miscellaneous part, eliminating wearing and tearing unnecessary in acting unit, improve the internal efficiency of acting unit.And the rotor 1 of conical screw shape by the cell wall of one end (A end) that cross section is little one end (B end) thread groove 17 large to cross section surface area and increase gradually from the distance of axis, under identical air pressure, moment also increases gradually, the expanding gas that such structure can enable the pressure be applied to it reduce gradually produces enough large moment of torsion acting, thus can realize the object of the cascaded utilization of energy of expanding gas.
Between more than 100 year of heat engine generation, the energy that fuel all can not produce by all types of variable capacity heat engines used in world wide carries out cascade utilization, sub-fraction wherein is only make use of in the process using the energy, and the most energy has been slatterned in the mode of waste heat, its reason can not make the expanding gas of lower pressure produce enough moment of torsion actings with regard to being.Creativeness of the present invention is the Land use systems changing heat energy, makes the gas of lower pressure also can produce enough moment of torsion actings, thus the most energy of fuel is utilized effectively.
The expansive force of gas acts on rotor 2 and also can produce an axial force, the scheme that section Example of the present invention provides for this reason makes each acting unit group 12 comprise the acting unit of two mirror images of each other, the rotor 2 of these two acting unit is rigidly connected by mirror-image fashion, make its transmission direction in expansion stroke identical and the axial force direction of generation is contrary, offset axial force with this.Effectively get into smooth to make air work unit, will make sliding plug 5 after gas completes acting, get back to original position, also just need to make sliding plug 5 along its track reversing motion, because sliding plug 5 promotes by rotor 2 the rotation campaign coordinating rotor 2, this just needs rotor 2 counterrotating after working stroke terminates.In order to realize this purpose, the acting unit group 12 that section Example of the present invention is provided with two corresponding acting unit groups 12, two corresponding can be connected by rotor linking mechanism 10.When an acting unit group 12 carries out expansion stroke, sliding plug 5 is held by the A of rotor and is slided into B end, rotor 2 linkage rotation of another acting unit group 12 corresponded is exhausted stroke or sliding plug 5 holds the A shifting rotor onto to hold by the B of rotor by compression stroke, when the sliding plug 5 of another acting unit group 12 arrive rotor A end carry out expansion stroke time, the rotor opposite spin of the aforementioned acting unit group 12 corresponded can be driven again, sliding plug 5 is pushed to the A end of rotor.Two corresponding acting unit groups 12 hocket expansion stroke, and its rotor 2 is hocketed forward and reverse reciprocating rotary, thus promote sliding plug 5 and reciprocatingly slide between B end and the A end of rotor, and acting unit is got into smooth stably.Because rotor 2 needs counterrotating, gearing can not be there is with line shaft 4 in the process, so arrange unilateral bearing 6 to make rotor transfer motion power axle 4.The effect of unilateral bearing 6 is, transfer motion power axle 4 time rotor 2 rotates along a direction, and gearing does not occur with line shaft 4 when counterrotating, dallies, is similar to the working principle of bicycle freewheel.Charging-up lubricant oil in thread groove 17 between larger one end (B end), rotor cross section and sliding plug 5, two corresponding acting unit groups 12 are communicated with each other by grease channel 9, lubricant oil can be made back and forth to flow in two corresponding acting unit groups 12, acting unit is played to the effect of lubrication and cooling.In order to make rational in infrastructure, the compact in design of motor, section Example of the present invention makes corresponding acting unit group 12 drive two line shafts 4 respectively, and make two line shaft 4 common driving output shafts 11 by shaft transmission 8, output shaft 11 is rotated in the same direction.Like this, corresponding acting unit group 12 replaces transfer motion power axle 4, two line shafts 4 by unilateral bearing 6 and replaces transmission output shaft 11, makes output shaft 11 externally outputting power.
