Technical field
The present invention relates to a kind of movement conversion mechanism, specifically relate to a kind of to-and-fro motion and rotatablely move the mechanism of conversion mutually.The present invention relates to the parts of forming said mechanism simultaneously, and the equipment that uses said mechanism to obtain.
Background technique
In machinery, need to realize to-and-fro motion in many instances and rotatablely move between mutual conversion.For example, reciprocating internal combustion engine need be converted to rotatablely moving of bent axle with the linear reciprocating motion that piston produces under the pressure of explosion of burning mixture promotes; In contrast, compressor need be converted to external motor-operated crankshaft rotating the linear reciprocating motion of piston.Above-mentioned two kinds of conversions are except the driving link difference, and it is consistent that motion of mechanism is required, and therefore, can realize that linear reciprocating motion is converted to the mechanism that rotatablely moves, and can be used for also generally that realizing rotatablely moves is converted to linear reciprocating motion.
Some linear reciprocating motions are provided under the prior art and have rotatablely moved the mechanism of conversion mutually.Usually under the technology, adopt connecting rod to realize above-mentioned conversion.Present most of internal-combustion engine, compressor all use connecting rod.The characteristics of this mechanism are, need to be connected between linear reciprocating motion spare and the rotating motion part by the connecting rod that swings back and forth, because the motion of connecting rod is to swing back and forth, this motion is a kind of compound movement, be difficult to carry out the inertia equilibrium of forces, and the swing of connecting rod can increase the side pressure of piston to the motion guide rail sidewall, cause the increase of frictional force, in addition, the existence of connecting rod also makes this mechanism need to possess certain length on vibration-direction, makes its size be difficult to further dwindle.
In order to address the above problem, Chinese patent literature CN85100358B discloses a kind of " crankshaft circular slide block reciprocating piston internal combustion engine ", Chinese patent literature CN1067741C discloses a kind of " crank and double-round slide reciprocating piston internal combustion engine ", and Chinese patent literature CN1144880A discloses a kind of " crank and multi-round slide reciprocating piston internal combustion engine ".The common feature of above-mentioned internal-combustion engine is that the connecting rod to internal-combustion engine under the current techique has carried out thorough improvement, adopts the smooth block with eccentric circular hole to replace connecting rod.Described eccentric circle slide block is cylindrical, and has the eccentric circular hole that is parallel to cylinder axis, and this eccentric circular hole is used to pass the crank pin of bent axle.The piston of this internal-combustion engine comprises the bizet and the guide portion that is connected two bizets at two ends, wherein has circular hole on the guide portion, and the outer diametric plane of the aperture surface of this circular hole and above-mentioned smooth block matches, and is called circular slider accommodation hole; Described smooth block promptly is placed in the circular slider accommodation hole that matches with its periphery in the piston guide portion.When described piston be subjected to combustion gas in the cylinder promotion and in cylinder during to-and-fro motion, described eccentric circle slide block rotates around the center of circle of himself, and and then drive crankshaft reversal and rotate, thereby the to-and-fro motion of piston is converted into rotatablely moving of bent axle, again by the outside transmitted power of the rotary component that is connected with bent axle.The thought of above-mentioned patent also can be migrated in compressor or the evacuator easily, obtains crank round slider compressor or crank round slider evacuator.
Owing to cancelled connecting rod, its complicated reciprocally swinging also just is cancelled, and makes above-mentioned circular slider-crank mechanism can realize the complete equilibrium of inertial force easily; Equally, the side pressure to the guiding cheekn of reciprocating motion of the pistons that forms owing to the swing of connecting rod also can disappear, and the frictional force when making reciprocating motion of the pistons significantly reduces; In addition, behind the cancellation connecting rod, the size that can significantly dwindle vibration-direction, the size of entire mechanism is significantly dwindled.
But still there are some significant disadvantage in above-mentioned motion, has limited the utilization of circular slider-crank mechanism.At first, smooth block is arranged in the circular slider accommodation hole of piston in this mechanism, and crank pin needs to pass the eccentric opening on the smooth block again, and it is too concentrated that each part of this position is crossed, and the crank pin size is restricted, the power transmission of can not loading greatly.Secondly, during motion, the bearing axis speed height of smooth block and crank pin, and be in the mechanism depths, be difficult for heat radiation; Another problem is, the stroke-bore ratio of this mechanism is subjected to the influence of smooth block size, can not be very high, and might make burning mixture light the pressure of explosion that the back produces can't fully discharge at every turn, causes fuel economy to descend.
