Description
Technical field
The utility model relates to a kind of engine part, especially relates to a kind of smooth block that is used for circular slider-crank mechanism.The utility model relates to a kind of circular slider-crank mechanism that uses this smooth block simultaneously, and further, the utility model also relates to the machinery of using this circular slider-crank mechanism, comprises internal-combustion engine, compressor and evacuator.
Background technique
Reciprocating internal combustion engine or compressor all need to realize the conversion between the rotatablely moving of the to-and-fro motion of piston and bent axle, wherein, reciprocating internal combustion engine is that the to-and-fro motion with piston is converted into rotatablely moving of bent axle, and reciprocal compressor then is the to-and-fro motion that rotatablely moving of bent axle is converted into piston.Under the present current techique, above-mentioned transfer process all needs to use connecting rod.Because the existence of connecting rod makes machine huge, heavy in the connecting rod, can't complete equilibrium.
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 have circular hole on the guide portion, the outer diametric plane of the aperture surface of this circular hole and above-mentioned smooth block matches, and described smooth block promptly is placed in the circular 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.
In the circular slider-crank mechanism that above-mentioned patent provides, smooth block is a core part, plays the effect of similar connecting rod in the connecting rod.In disclosed various patent, all need to use smooth block about circular slider-crank mechanism.
The eccentric opening of smooth block is used for cooperating with crank pin, and crank pin will rotate in this eccentric opening.Therefore, need to install sliding bearing or rolling bearing in the eccentric opening, so that cooperate with crank pin.Described sliding bearing uses axle sleeve or bearing shell, if use bearing shell, and the then general bearing shell group of forming by two bearing shells that can synthesize a complete sliding bearing of using.
Generally, because eccentric opening is longer, no matter use axle sleeve or bearing shell, on in eccentric opening, all needing to be divided into axle sleeve or bearing shell axially two sections, two sections axle sleeves or bearing shell are respectively from two end faces of eccentric opening eccentric opening of packing into, leaving gap between two sections, the oilhole on the eccentric opening promptly is arranged on this interstitial site.In the circular slider-crank mechanism, generally on bent axle, main oil gallery axially is set, the branch oil duct that connects diametric plane outside this main oil gallery and the crank pin is set on crank pin, the distribution of lubrication oil of main oil gallery is arrived the surface of friction pair of crank pin and sliding bearing along it.The interstitial site that the position just in time stays at two sections sliding bearings is offered in this minute outlet of oil duct, makes lubricant oil pass through the eccentric opening oilhole outflow that this interstitial site is provided with, and the surface of friction pair of smooth block and piston is lubricated.Therefore, above-mentioned sliding bearing is divided into two sections, and forms the gap between two sections, and is unobstructed significant for the lubricating oil path of whole circular slider-crank mechanism.It is to increase the enabling capabilities of sliding bearing that above-mentioned sliding bearing is divided into another meaning of two sections.Under the short situation of eccentric opening, also can adopt one section axle sleeve.And on axle sleeve, hole and fluting.
When eccentric opening cooperates with crank pin by sliding bearing, axial float might appear in described bearing or bearing shell, when shifting amount is big, just might move to original interstitial site, oilhole on the eccentric opening at this place is shut, can't provide lubricant oil on the friction pair between the circular slider accommodation hole inner edge surface of smooth block outer edge surface and piston, the lubricant oil supply of final entire mechanism is not smooth, jeopardizes the normal operation of entire mechanism.
The model utility content
At the problems referred to above, the technical problem that the utility model solves is, a kind of smooth block is provided, and this smooth block can make sliding bearing be installed to and obtain the location in the eccentric opening afterwards, limits its axial float, avoids producing oilhole.The utility model provides the circular slider-crank mechanism that uses above-mentioned smooth block to constitute simultaneously; The utility model also provides the machinery of using above-mentioned circular slider-crank mechanism simultaneously.
The utility model provides a kind of smooth block, is used for circular slider-crank mechanism, and the hole wall of the eccentric opening of this smooth block is provided with the protruding circle that axially has width; Be installed in bearing shell or axle sleeve in this eccentric opening, be divided into left and right sides two-part, two end faces are packed into from about the eccentric opening respectively, and prop up this protruding circle and obtain axially locating; The oilhole that leads to the smooth block outer rim is set in this protruding circle position.
Preferably, the neutral position of the position of described protruding circle on described eccentric opening is axial.
Preferably, the height of described protruding circle meets the following conditions: behind pack in this eccentric opening bearing shell or axle sleeve, the aperture surface of this protruding circle is not higher than the bearing shell that is installed in this eccentric opening or the internal face of axle sleeve.
Preferably, two of described protruding circle end faces are parallel to the eccentric opening end face.
The utility model also provides a kind of circular slider-crank mechanism, and this circular slider-crank mechanism adopts the described smooth block of above-mentioned each technological scheme.
The utility model also provides a kind of machinery, and this machinery adopts above-mentioned circular slider-crank mechanism; This machinery specifically is internal-combustion engine, compressor or evacuator.
The smooth block that the utility model provides is provided with the protruding circle of locating usefulness on the eccentric opening hole wall, this protruding circle can carry out the axis location to the sliding bearing of the eccentric opening of packing into, avoids the axial float of sliding bearing.The width of this protruding circle is exactly two sections gaps between the sliding bearing, and the oilhole of eccentric opening promptly is opened on this protruding circle.By said structure, can guarantee that the oilhole of eccentric opening can not be blocked, avoid oil circuit freely not produce the problem of excessively heated axle.
Owing to be provided with above-mentioned protruding circle, sliding bearing is had the axial limiting effect, can reduce the axial float of sliding bearing, make the stable cooperation of friction pair.
