Embodiment
In the circular slider-crank mechanism of double-round slide or three smooth blocks, dynamic balance slide block cooperates with reciprocating piston, to-and-fro motion inertial force can be converted into inertial centrifugal force.In the utility model, provide a kind of dynamic balance slide block.
Dynamic balance slide block of the present utility model comprises circular slider accommodation hole and two the relative and directed side that match with the runway of described crank circular slider internal-combustion engine that are used for ccontaining smooth block; Wherein, described directed side is adjacent round-corner transition between the face at the edge of the reciprocating direction of dynamic balance slide block.
Below in conjunction with accompanying drawing dynamic balance slide block of the present utility model is described in detail.
The shaft side figure of the dynamic balance slide block that Fig. 4 provides for the utility model.
As shown in Figure 4, dynamic balancing smooth block 1 of the present utility model is flat cuboid, and described dynamic balance slide block 1 is provided with circular slider accommodation hole 2.Wherein, described circular slider accommodation hole 2 is used for the smooth block of the circular slider-crank mechanism of ccontaining double-round slide or three smooth blocks (perhaps multi-round slide), its size matches with corresponding smooth block, and when making smooth block in being installed on described circular slider accommodation hole 2, smooth block can rotate.
Described circular slider accommodation hole 2 runs through the thickness direction of described dynamic balancing smooth block 1.
Described dynamic balance slide block 1 also has two relative and directed side that match with the runway of crank circular slider internal-combustion engine.As shown in Figure 4, described dynamic balance slide block 1 reciprocating direction is as shown in arrow 3, and two the relative side 1-1 and the 1-2 of dynamic balance slide block 1 are directed side.The shape of described directed side 1-1 and 1-2 matches with the dynamic balance slide block runway of crank circular slider internal-combustion engine, and for example, when described dynamic balance slide block runway was arc-shaped surface, described directed side 1-1 and 1-2 also were arc-shaped surface.Thereby guarantee that runway provides leading role to dynamic balance slide block 1.
In addition, described dynamic balance slide block 1 also can have other shape, but it has the circular slider accommodation hole that is used for the directed side that matches with runway and is used for ccontaining smooth block at least.Here no longer describe in detail.
In embodiment of the present utility model, described directed side 1-1 and 1-2 are adjacent round-corner transition between the face at the edge of described dynamic balance slide block 1 vibration-direction (also being the indicated direction of arrow 1 in the present embodiment).Round-corner transition district 4 as shown in Figure 4.That is to say, directed side 1-1 in the present embodiment and 1-2 and described dynamic balance slide block 1 vibration-direction the incline between the vertical face be set to round-corner transition.
Because after dynamic balance slide block 1 was assemblied in crank circular slider internal-combustion engine, when described crank circular slider internal-combustion engine was worked, dynamic balance slide block 1 can move reciprocatingly along the runway of crank circular slider internal-combustion engine.And dynamic balance slide block 1 can produce swing owing to be subjected to the effect of side pressure couple when commutation, and the directed side 1-1 of dynamic balance slide block 1 and 1-2 can the scratch runways at the incline of vibration-direction.This not only can make the reduction in strength of internal combustion (IC) engine airframe, and, also can influence the counterbalance effect of dynamic balance slide block to whole motion.And in the present embodiment, be set to round-corner transition by described incline, can overcome above-mentioned problem, when dynamic balance slide block 1 to-and-fro motion commutates, round-corner transition district 4 has certain buffer function, thereby can reduce or overcome the problem of scratch runway, can guarantee dynamic balance slide block 1 proper functioning.

In addition, dynamic balance slide block 1, need change the quality and the central position of dynamic balance slide block 1, to adapt to different situations for satisfying the counterbalance effect under different situations as the parts that play balanced action in the movement conversion mechanism of crank round slider.
In the utility model, a kind of structure that changes the quality of dynamic balance slide block 1 is provided, in the utility model, the counterweight space is set in dynamic balance slide block 1, be used to be placed in the different material of density of dynamic balance slide block 1 own, with the total quality of change dynamic balance slide block 1 and the position at center.Fig. 5 and Fig. 6 show a kind of schematic representation with the dynamic balance slide block in counterweight space of the present utility model.Wherein, Fig. 6 is the shaft side figure after Fig. 5 cuts open along AA ' direction.
As shown in Figure 5 and Figure 6, be provided with counterweight space 6 in dynamic balance slide block 1, described counterweight space 6 can be cylindrical or square, also can be other shape; Can the different material of ccontaining density, for example,, can in counterweight space 6, irritate lead in described counterweight space for increasing dynamic balance slide block 1 total quality.Certainly, can also insert other material, give unnecessary details no longer one by one here.
The opening 5 in described counterweight space 6 be arranged at described dynamic balance slide block vibration-direction vertical plane, as shown in Figure 5 and Figure 6, can be convenient in counterweight space 6, insert different materials by described opening 5.In addition, described opening 5 also can be arranged at the plane identical with one of them end face of described circular slider accommodation hole, no longer describes in detail here.Bolt or cover plate are set with described closure of openings at described opening 5 places.
In addition, quality and position of centre of gravity that balancing weight changes dynamic balance slide block 1 can be set also by end at described dynamic balance slide block 1 vibration-direction, corresponding, need on dynamic balance slide block 1, linkage structure be set.
In addition, for reducing the frictional loss of dynamic balance slide block, the surperficial sintering that matches with runway of dynamic balance slide block or spraying bearing material layer again, perhaps with surface that runway cooperates on several of bolt the inserting of copper or aluminium matter.Described inserting not only can be improved abrasive resistance, but also can change the quality and the central position of dynamic balance slide block integral body.
In addition, the dynamic balance slide block described in the above embodiments can be arranged in the crank circular slider internal-combustion engine, constitutes crank circular slider internal-combustion engine.
Though the utility model with preferred embodiment openly as above; but it is not to be used for limiting the utility model; any those skilled in the art are not in breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection domain of the present utility model should be as the criterion with the scope that the utility model claim is defined.
