Description
The invention belongs to a kind of mechanical transmission for the new drive device of rotary motion and linear reciprocating motion, and in particular to a kind of transmission device that rotary motion is mutually changed with linear reciprocating motion.
It is well known that in existing skill wood, rotary motion mutually changes widely used crankshaft-link rod drive technology, such as application in piston with linear reciprocating motion.And there are several contradictions in this drive technology：One is even to swing to cause the side wear between piston and casing wall and the contradiction of volume.If connecting rod be directly connected with piston（Such as：Internal combustion engine, either simplex air compressor machine etc.）, though equipment can be made to obtain smaller size smaller, the side wear of piston and casing wall, unfavorable sealing is also easy to produce；If piston passes through an axostylus axostyle（Or piston rod）It is connected with connecting rod（Such as duplexing air compressor machine）, though the side wear caused by the swing of connecting rod between piston and casing wall can be eliminated, volume is more much bigger than the former；Two be vibration caused by alternation inertia, abrasion and the contradiction of volume.The object of linear reciprocating motion has alternation inertia, although by reducing single chamber volume, increase cylinder number, can reduce impact shock and abrasion using balanced measure etc., but the equipment being joined directly together for piston and connecting rod is difficult to further reduce using impact mitigation measure, though easily using impact mitigation measure to the equipment that piston is connected by piston rod with connecting rod, volume is more much bigger than the former；Three be the contradiction of kinetic characteristic and economic benefit.As internal combustion engine, the heat energy into the fuel in people's cylinder is set efficiently to be transformed into mechanical energy, it is necessary to fuel is burnt under same high compression ratio and it is necessary to burning completely.Because the burning of fuel needs the regular hour, this requires piston to have the static time in top dead centre, the continuity between rotary motion and piston linear reciprocating motion due to crankshaft-linking rod drive mechanism bent axle, it can not provide a static time in top dead centre to piston, thus it cannot be guaranteed that the fuel for entering people's cylinder fully burns under same high compression ratio, but piston is descending on one side, fuel side burning, therefore can not be efficiently by thermal energy into mechanical energy.Also the economic benefit of internal combustion engine therefore can not be improved efficiently with Waste Heat Recovery technology.
It is an object of the invention to provide a kind of rotary motion and the new drive device of linear reciprocating motion, this mechanical driving device can be used in a variety of occasions, it can be such that rotary motion is mutually changed with linear reciprocating motion, if using on piston, the volume that it can reduce equipment can eliminate the side wear between piston and casing wall again, meanwhile, base easily further reduces impact shock and abrasion using buffer technology；For internal combustion engine, certain quiescent time can be also provided in top dead centre for piston, can fully be burnt under same high compression ratio with protecting the fuel levied into people's cylinder, efficiently thermal energy into mechanical energy, and be useless
Recuperation of heat utilizes and creates condition for validity.
The purpose of the present invention is completed by following technical proposals.
The present invention is the new drive device of a kind of rotary motion and linear reciprocating motion, and its structural feature is：The transmission device is made up of bent axle, alien, rotator frame and the part of push rod four that is connected on rotator frame or so frame side；Crankshaft installed is on crankshaft base, and it is made up of main bottle neck, crank, secondary bent neck；Rotator frame and the alien in rotator frame are arranged between two cranks of bent axle, and secondary bent neck couples with alien, and the upper and lower parts of rotator frame are provided with the loose slot of rotator frame.During work, bent axle is driven as driving shaft by power, then alien is moved by secondary bent neckstrap to rotate simultaneously, rotator frame and push rod are under the drive that alien moves, rotator frame does reciprocating linear motion along loose slot, and push rod follows rotator frame to move, if installing upper piston at the two ends of push rod, push rod will promote piston to be done reciprocating linear motion in cylinder, so as to reach the purpose of the present invention.
The present invention is when implementing, and push rod cross sectional shape is circular or square.
The present invention in the specific implementation, alien's profile to be square, in set cylindrical bore, rotator frame munnion side inner surface is planar shaped.
In the specific implementation, alien's profile can also be cylindrical shape to the present invention, and the concave surface of rotator frame munnion side inner surface is arc.
The transmission device of the present invention has the advantages that drive mechanism is reasonable, using effect is good, if the transmission device is substituted into existing crankshaft connecting rod system with piston, then with following features：
1st, bent axle, alien, the rotator frame transmission mechanism that a crank throw is constituted, can promote two pistons to be operated simultaneously, and the volume and weight of average single cylinder is more many smaller than crankshaft connecting rod system, and eliminates the side wear between piston and casing wall.
2nd, the equipment that alternation inertia ratio piston and connecting rod of the invention are directly connected to is big, but is easily reduced or eliminated its impact influence using buffer technology.If if overwhelming majority impact influence is eliminated, a kind of form of common mode configuration can be used completely as internal combustion engine（I.e.：The piston of multicylinder engine shares a crank throw, and each cylinder is distributed around bent axle by equal angle, and centre distance of each cylinder along bent axle axial direction is smaller than the diameter of cylinder holes）, making the volume and weight of engine is more reduced.
If buffer technology can need not be used by the 3, being used for two stroke engine, because a cylinder is in expansion space stroke, another cylinder must Chu Yu Ya Shrink strokes, be exactly the buffering to piston inertia to gas Ya Shrink.
4th, when the alien in the present invention using drum-shape, in the middle part of the inner surface of rotator frame munnion side uses arcs of recesses,
Alien is when four arcwall faces are rolled, and piston will stay on top dead centre and remain stationary as, and this just provides guarantee for the complete burning of fuel, efficiently thermal energy into mechanical energy, also to create advantage efficiently with Technogy of Waste Gas Heat.Due to the burning time of fuel being separated Cong Ya Shrink times and power done time, this is just five phase engines for new high-efficiency internal combustion engine（One work period of engine is divided into intake period, compression period, main combustion period, work done phase, exhaust cycle）Or three phase engines（Compression period, main combustion period, work done phase）Deng generation established technical foundation.New work engine has particularly significant following several big advantage-a better than Qu Lianfa motivations, piston in top dead centre with certain stop angle（Residence time）Burning time is separated from compression time and power done time, the fuel that ensure that into cylinder can efficiently burn under same Gao Ya Shrink ratios, make the taller many of highest pressure of the highest pressure than Qu Lian in cylinder, the energy that fuel is discharged simultaneously is all identical to the operating distance of piston and equal to piston stroke, and two defective regions of Qu Lianfa motivations are eliminated in addition（Defective region, negative work area：Due to shifting to an earlier date oil spout [igniting], the energy that fuel is discharged will hinder up [hand diesel engine, strength is smaller, is also easy to produce reversing, and this is the result of negative work effect] of piston, and what piston was made is negative work；Poorly efficient area：After top dead center is crossed, piston is descending on one side, fuel side burning.Piston is more descending, and immediate compression ratio is just smaller, and energy conversion efficiency is lower, and part of fuel even has little time burning and just excreted with waste gas）.
B, the moment of torsion produced are especially big, and in theory, in expansion space stroke, the moment of torsion of Qu Lianfa motivations is zero-based, and the moment of torsion for the new work engine being made up of the present invention is from more than LFmWhat sin (a/2) 12 started（L piston strokes in formula； FmThe instantaneous highest total pressure that piston is obtained, instantaneous highest total pressure taller many of this power than Qu Lian；A stops angle, and the full aduance than Qu Lian is big, and can also increase initial torque by increasing a）, and the length of torque arm is more than L/2.
C, it can increase substantially business efficiency efficiently with Waste Heat Recovery reutilization technology.
