Description
Technical field
The present invention relates to circular slider-crank mechanism, particularly relate to a kind of body for circular slider-crank mechanism, the present invention relates to internal-combustion engine and the compressor that uses above-mentioned body simultaneously.
Background technique
The motion of conventional engines is connecting rod.Under this motion, the to-and-fro motion of piston need to pass to bent axle by connected connecting rod, and in movement process, connecting rod makes piston be subject to the periodicity lateral force that changes with higher-order function along with the motion do swing back and forth of piston.
Because the existence of connecting rod, there are the shortcomings such as bulky, heavy, that balance quality is poor in the connecting rod internal-combustion engine, in order to address these problems, Chinese patent literature CN85100358B discloses a kind of " crankshaft circular slide block reciprocating piston internal combustion engine ", the characteristics of this internal-combustion engine are to have cancelled connecting rod, the smooth block that employing has eccentric circular hole matches with the piston assembly of particular design, realizes that the straight reciprocating motion of piston is to the conversion that rotatablely moves.
Take above-mentioned patent documentation as the basis, Chinese patent literature CN1067741C discloses a kind of " crank and double-round slide reciprocating piston internal combustion engine ".This internal-combustion engine adopts the mode of piston and dynamic balance slide block pairing, and both move at the to-and-fro motion track that is 90 degree layouts respectively, mutually overcome point alive between piston and the dynamic balance slide block, can avoid adopting gear mechanism to overcome the impact of point on mechanism's life-span of living; Simultaneously, the motion of piston and dynamic balance slide block makes a concerted effort to form the centrifugal force that points to the crank pin center from crankshaft center, is convenient to carry out balance, makes this mechanism can reach desirable dynamic balancing effect.The problem of this mechanism is, has distance L along crankshaft center line between described piston and the dynamic balance slide block, makes both form moment of flexure at bent axle, makes the whole mechanism can't complete equilibrium.
In Chinese patent literature CN1144880A, a kind of three circular sliding block mechanisms are then disclosed, this mechanism adopts three reciprocating motion elements to form the reciprocating motion element group, the to-and-fro motion track of three reciprocating motion elements is mutually vertical, the quality of the reciprocating motion element in the middle of wherein being positioned at is the quality sum of other two reciprocating motion elements, and the quality of the smooth block that the reciprocating motion element in the middle of being arranged in is installed is the quality sum of smooth block that is installed in the reciprocating motion element on both sides.Three smooth blocks formation circular slider set that interfixes, the smooth block homophase that wherein is positioned at both sides is installed, and the smooth block in the middle of being positioned at and the smooth block of both sides are installed with 180 ° of phase differences.The eccentric opening of above-mentioned three smooth blocks is enclosed within on the same crank pin.In the said mechanism, all to-and-fro motion inertial force finally can synthesize a rotating inertia force, are convenient to realize balance by balancing component is set.And, because middle reciprocating motion element is set to just to make whole mechanism can not form moment of flexure on bent axle in the neutral position of the reciprocating motion element of both sides dimensionally, that is to say that in theory, this structure can realize completely counterbalance effect.But the good dynamic balancing effect of this mechanism depends on the middle reciprocating part of its setting, and whole mechanism is too complicated, and has increased the quantity of reciprocating motion element, needs to increase the length of crank pin, causes axis rigidity to reduce.In addition, the manufacture cost of machine also significantly increases, and reliability also descends to some extent.For requiring the less machine of size, can not adopt said mechanism.
For addressing the above problem, the claimant has proposed to adopt the circular slider-crank mechanism that only has two reciprocating motion elements of three smooth blocks formation.The schematic representation of a possibility form of this mechanism only illustrates the main movement members such as piston, smooth block as shown in Figure 1 and Figure 2 among the figure.
As shown in Figure 1 and Figure 2, in this mechanism, comprise a two-way ram A and a single action piston B, wherein, an intermediate space C in the middle of the guide portion of two-way ram A is positioned at is divided into first row guide portion I and secondary series guide portion II two row; The guide portion of single action piston B then passes from the intermediate space C of the guide portion of described two-way ram A.All be provided with circular slider accommodation hole on the first row guide portion I of described two-way ram and secondary series guide portion II, like this, cophasing is installed left smooth block D, right smooth block E on two-way ram A; On the guide portion of single action piston B, settled middle circle slide block F to be 180 ° mode with above-mentioned left smooth block D and right smooth block E phase place, above-mentioned three smooth blocks interfix, and consist of three circular slider set.
By said mechanism, just in the circular slider-crank mechanism that adopts two reciprocating parts, use three circular slider set, thereby can obtain the advantage of three circular slider set, effectively reduced again the complexity of whole mechanism simultaneously.Said mechanism also has other form, for example, single action piston is designed to double-row type; Perhaps two pistons are two-way ram, and one of them is double-row type, and another one is single-column type.
In order to make above-mentioned circular slider-crank mechanism normal operation, it is extremely important to design the body that is appropriate to said mechanism.This body not only needs to support for above-mentioned motion provides effective motion, and wishes that it is relatively simple for structure, and is easy to manufacture, can effectively reduce manufacture cost like this.
