Technical field
The present invention relates to back and forth-rotary motion conversion mechanism, especially relate to back and forth a kind of dynamic balance slide block of-rotary motion switching mechanism H-shaped engine body.The present invention relates to the equipment using above-mentioned dynamic balance slide block simultaneously.
Background technique
In machinery, need the mutual conversion realized between to-and-fro motion and rotary motion in many instances.Such as, reciprocating internal combustion engine needs the rotary motion linear reciprocating motion that piston produces under the pressure of explosion of burning mixture promotes being converted to bent axle; In contrast, compressor needs the linear reciprocating motion external motor-operated crankshaft rotating being converted to piston.Above-mentioned two kinds of conversions, except driving link difference, require it is consistent to the kinology of mechanism, therefore, can realize the mechanism that linear reciprocating motion is converted to rotary motion, generally also may be used for realizing rotary motion and be converted to linear reciprocating motion.
The mechanism that some linear reciprocating motions and rotary motion are changed mutually has been provided under prior art.Under usual technology, connecting rod is adopted to realize above-mentioned conversion.Current most of internal-combustion engine, compressor all use connecting rod.The feature of this mechanism is, linear reciprocating motion part is connected with the connecting rod needed between rotating motion part by swinging back and forth, motion due to connecting rod swings back and forth, this motion is a kind of compound movement, is difficult to carry out inertia equilibrium of forces, and the swing of connecting rod can increase the side pressure of piston to motion guide rail sidewall, cause the increase of frictional force, in addition, the existence of connecting rod also makes this mechanism on vibration-direction, need to possess certain length, makes its size be difficult to reduce further.
In order to solve the problem, Chinese patent literature CN85100358B discloses one " crankshaft circular slide block reciprocating piston internal combustion engine ", Chinese patent literature CN1067741C discloses one " crank and double-round slide reciprocating piston internal combustion engine ", and Chinese patent literature CN1144880A discloses one " crank and multi-round slide reciprocating piston internal combustion engine ".In addition, the application number that the applicant proposed on October 16th, 2009 is in the Chinese patent application of 200910236026.5, also proposed a kind of axle system adopting end axle-moving axis to be combined to form coordinate with reciprocating part form reciprocal-rotation movement mutual conversion mechanism.
The common feature of above-mentioned Novel rotary-reciprocating rotary converting mechanism, is do not re-use the middle transition element of connecting rod as to-and-fro motion and rotary motion, avoids the problem because connecting rod causes.First, owing to there is not the compound movement that connecting rod is introduced, make all elements in motion all be in simple harmonic motion state, be convenient to carry out reciprocal inertia force and rotatory inertia equilibrium of forces, and real complete equilibrium can be realized.Secondly, owing to there is not connecting rod, make to-and-fro motion track no longer exists for and arrange connecting rod and the size that increases, the bulk that whole mechanism is occupied is able to remarkable minimizing.
Owing to there is not connecting rod, the space of back and forth above-mentioned-rotary motion conversion mechanism is arranged also different from the connecting rod of existing usual technology.Especially for the above-mentioned Novel rotary-reciprocating rotary converting mechanism with three reciprocating motion elements, not only can realize the complete equilibrium of its reciprocal inertia force and reciprocal inertia force square, and can make whole arrangement of mechanism in the body of compact structure.For in the body that above-mentioned three reciprocating motion elements provide, a kind of typical form is H type body.
The structural representation of above-mentioned H type body as shown in Figure 1 and Figure 2.Wherein, Fig. 1 is the positive apparent direction schematic diagram of this H type body, Fig. 2 be this H type body overlook direction schematic diagram.This body illustrated is for a kind of internal-combustion engine.This internal-combustion engine has three reciprocating motion elements, and be two pistons and a dynamic balance slide block respectively, described piston can be single action piston or two-way ram.Accordingly, described body is for which providing three to-and-fro motion tracks, the to-and-fro motion track for two pistons provide respectively, i.e. the first cylinder 1 (the first to-and-fro motion track), the second cylinder 2 (the 3rd to-and-fro motion track), and the runway 4 (the second to-and-fro motion track) provided for dynamic balance slide block; In addition, described body is also rotating motion part, and namely the bent axle of circular slider-crank mechanism or the axle system of end axle-moving axis provide main bearing hole 3, for above-mentioned rotating motion part provides rotary support.Wherein, the axis of described first cylinder 1, second cylinder 2 is parallel to each other, and the plane at above-mentioned two axis places is called the first plane; The axis of described main bearing hole 3 to be positioned at equally in described first plane and with the axes normal of described first cylinder 1, second cylinder 2.4, described runway is clipped between described first cylinder 1 and the axis of the second cylinder 2, the axis of runway 4 and the intersect vertical axis of described main bearing hole 3, and forms the second plane, and this second plane orthogonal is in described first plane.Runway 4, as the to-and-fro motion track of dynamic balance slide block, can be designed to different shape of cross sections.Generally there are two kinds of selections, namely circular or square.
In order to make the compact structure of whole motion, second to-and-fro motion track (runway 4) and the first to-and-fro motion track (the first cylinder 1) be adjacent, the 3rd to-and-fro motion track (the second cylinder 2) of above-mentioned H type body have the position be superimposed each other, make the position that this second to-and-fro motion axis of an orbit is upwards superimposed with the first to-and-fro motion track and the 3rd to-and-fro motion track, there is the position that an aperture surface is long and narrow, and when the position, medial axis of the first to-and-fro motion track and the 3rd to-and-fro motion track, this position is narrower and small.This position is called as the ridge area of the second to-and-fro motion track.Please refer to Fig. 3, this figure is the stereogram of a H type body, can find out the first cylinder 1, first cylinder 2 of this H type body, main bearing hole 3 and runway 4 in this figure.This figure overlooks downwards at a certain angle from the end face of H type body, can find out ridge area 4-1 wherein.Referring to Fig. 4, this figure be this H type body along the stereogram after described second section on plane, more clearly can find out the scope of ridge area 4-1 from this figure, four arrow pointed location that ridge area 4-1 indicates are the scope at 4-1 place, ridge area.
Because ridge area area is long and narrow, when dynamic balance slide block or other forms of reciprocating motion element are in the second to-and-fro motion track during to-and-fro motion, this position rigidity is the poorest, under the complex stress effect that body bears, the distortion of irregular complexity can be produced, cause in reciprocating part movement process, can not be formed with this position and coordinate smoothly, and then generation local can pull and scratch, ridge area is finally made to produce serious distortion, make the second reciprocating motion element cannot obtain the smooth and easy track of to-and-fro motion needs, affect the normal operation of whole mechanism.

Embodiment
Please refer to Fig. 5, this figure is the stereogram of a kind of H type body that first embodiment of the invention provides.This H type body is for adopting internal-combustion engine or the compressor of circular slider-crank mechanism or end axle-movable shaft mechanism.Internal-combustion engine is applied in the present embodiment for it.The observing angle of this stereogram overlooks downwards at a certain angle from the end face of this H type body to obtain.
As shown in Figure 5, this H type body has runway 4, this runway 4 is vertical with described first cylinder 1, second cylinder 2, and the first cylinder 1 and the second cylinder 2 crossing respectively with it in its both sides, and have superimposed position, these superimposed positions make whole housing construction closely, are conducive to alleviating body volume and weight.
But the existence at above-mentioned superimposed position, also makes described runway 4 become weak in the wall portion at this position.As can be seen from Figure 5, with the more close position of the first cylinder 1 and the second cylinder 2 medial axis on runway 4, inner wall surface thereof is narrower, forms described ridge area 4-1.This ridge area 4-1, as a part for runway 4, can rub with the dynamic balance slide block (not shown) run in this runway 4.This rubbing action makes this ridge area 4-1 be subject to the reciprocating forces constantly occurred.Because this ridge area 4-1 is weaker, causes and especially easily deform at this position, and due in mechanism's running, the external force that body is subject to is very complicated, make this weak part be subject to complicated effect of stress, its distortion is very complicated.First these distortion can cause the frictional force between ridge area 4-1 and dynamic balance slide block to increase, produce local further at ridge area 4-1 pull or scratch, these local damages can cause the more gross distortion of ridge area 4-1 further, finally cannot provide to-and-fro motion track smoothly for dynamic balance slide block.In addition, because this ridge area 4-1 is narrower, cause the fricative heat between wall portion and dynamic balance slide block sidewall to concentrate on narrow area, make this ridge area 4-1 also easily be heated and deform and ablation, can affect it equally for dynamic balance slide block provides track.
In order to solve the problem, in the present embodiment, runway 4 is set to be a bit larger tham other position at the diameter of this ridge area 4-1.The size being greater than other position is determined according to the diameter of this runway 4, and the diameter of runway 4 is larger, and ridge area 4-1 is greater than the size at other position also can be larger.Its dimensional range between 0.05mm-0.5mm, can certainly can exceed above-mentioned scope as the case may be as the case may be.The form that this size requirement can be adopted as the ridge area 4-1 setting tolerance of size different from runway 4 other parts realizes, also can directly for ridge area 4-1 arranges different size requirements.Can with domatic transition between above-mentioned ridge area 4-1 and the adjacent regions of runway 4, also can with ladder transition.As can be seen from Figure 5, be equipped with one horizontal line in the start bit on 4-1 top, ridge area, be exactly ridge area 4-1 size slightly greatly with the separatrix at other position of runway 4.Referring to Fig. 6, the sectional view of H type body of this figure for obtaining for H type body described in split surface subdivision with described second plane.Can know in this figure and find out that the upper and lower initial position of described ridge area 4-1 all has one horizontal line, that be the slightly large formation of ridge area 4-1 size with separatrix that is runway 4 other parts.
The length of described dynamic balance slide block in to-and-fro motion orbital direction is longer than the length of ridge area 4-1, when it runs in runway 4, in to-and-fro motion orbital direction, namely runway 4 axially, the outer wall of the upper and lower of this dynamic balance slide block contacts with the inwall of the 4-1 upper and lower, ridge area of runway 4 respectively, and in its reciprocating gamut, this dynamic balance slide block all the time simultaneously with ridge area more than 4-1 and the following location contacts of runway 4 inwall, like this, dynamic balance slide block obtains to-and-fro motion Orbital Support by runway 4 inwall beyond the 4-1 of ridge area, ridge area 4-1 then can not rub with dynamic balance slide block sidewall all the time.
In the above-described embodiments; also the diameter of whole ridge area 4-1 can not be set to be greater than other parts; but it is slightly large that the region of the one fixed width in the middle part of the 4-1 of ridge area is set to diameter; for ridge area 4-1; its position near middle part is weaker; therefore, to be subject to the effect that protection obtains best for intermediate section.The concrete size of the width in the middle part of above-mentioned ridge area, with runway 4 internal diameter to the support of dynamic balance slide block for according to arrange, make in the reciprocating gamut of dynamic balance slide block, can with runway 4 contact internal walls of upper and lower, avoid occurring dynamic balance slide block only in the situation of top or bottom and runway 4 contact internal walls, obtain stable rail supported to make the to-and-fro motion of dynamic balance slide block.
The present embodiment by by ridge area 4-1 or in the middle part of it diameter of one section arrange large compared with other position of runway 4, the outer wall of this dynamic balance slide block directly can not be contacted, but separated by a distance with runway 4 inwall of this enlarged diameter section.Like this, owing to there is not mutual friction, make the to-and-fro motion of dynamic balance slide block can not cause ridge area 4-1 directly stressed and frictional heat, ridge area distortion would not have influence on the motion of dynamic balance slide block, also can not scratch due to local and pull and the reason such as ablation produces further distortion.Aforesaid way makes the weakest link of runway 4 inwall obtain protection, extends the life-span of runway 4, also extends the working life of whole body.
The technological scheme of above-described embodiment also may be used for the H type body of other occasions.Wherein, runway 4 in this embodiment is special cases for the second to-and-fro motion track of H type body, in fact, the second to-and-fro motion track can be used to the cylinder that another piston provides track, and described dynamic balance slide block also can replace with other acting element accordingly.In a word, as long as the second to-and-fro motion track of H type body, no matter for which kind of occasion, all technique scheme can be adopted.
Similar with the invention thinking of above-mentioned first embodiment, also one section, the centre on vibration-direction on dynamic balance slide block sidewall can be set to diameter less, now, rely on dynamic balance slide block upper-lower section and runway 4 inwall against the support obtaining to-and-fro motion track.The range of movement of the upper-lower section of this dynamic balance slide block all outside ridge area, or in the outside of intermediate portion, ridge area, can obtain the protection to ridge area so too.Second embodiment is an example of this dynamic balance slide block below.
Please refer to Fig. 7, this figure is the front view of the dynamic balance slide block 5 that second embodiment of the invention provides.Referring to Fig. 8, this figure is the plan view of the dynamic balance slide block 5 that second embodiment of the invention provides.As can be seen from above-mentioned two figure, this dynamic balance slide block 5 is bluff body, and its longitudinal section entirety is rectangular, and the dual-side of its width direction is the circular arc sidewall relative with runway inwall.At the middle part of the axis of above-mentioned sidewall, there is one section of recessed position 5-1 being dimensioned slightly smaller than the upper and lower position of side.The recessed size of this recessed position 5-1 is determined according to the size of dynamic balance slide block 5, and its dimensional range is 0.05mm-0.5mm.This recessed position and adjacent regions can with domatic transition, also can directly with step transition.
During above-mentioned dynamic balance slide block work, its recessed position more than 5-1 contacts with the second to-and-fro motion track interior walls with following outer wall, and in whole reciprocatory movement, the above-mentioned position that this dynamic balance slide block and the second to-and-fro motion track interior walls directly contact all can not contact with the ridge area in the middle part of the second to-and-fro motion track, make this ridge area can not be subject to the direct effect power with the movement parts of its friction, also just avoid produce because of distortion pull, scratch and the problem such as ablation.
The above-mentioned technological scheme arranging recessed position at dynamic balance slide block sidewall suitable position, is easier to processing than the technological scheme increasing diameter dimension in the first embodiment in ridge area and obtains.
Although above-mentioned second embodiment is to provide a kind of dynamic balance slide block, in fact, the vibrational power flow at its recessed position also can be applied to other and be placed in reciprocating part in the second to-and-fro motion track.
The H type body of above-mentioned first embodiment's confession, can be applied to internal-combustion engine or compressor, obtains the embodiment being applied to internal-combustion engine or compressor.The dynamic balance slide block that above-mentioned second embodiment provides, can be applied to the internal-combustion engine or compressor that adopt H type body equally, obtain the embodiment being applied to internal-combustion engine or compressor.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
