Description

The two propelling movement drive units of symmetric type

Technical field the utility model relates to and is used for the indirect drive part of drive machines, and the more definite workpiece that more particularly by this device powerhouse ground connection is passed to machine exactly does work its running.

The well-known machine of background technique is on-stream must be to consume certain energy as cost, the consumption of energy adds axial force and radial force nothing more than the frictional resistance of machine itself, wherein frictional resistance is inevitable, as in the running with the friction of air and each Component relative movement friction, and axial force can have only one of them with radial force according to the different of technological requirement, also can the two double depositing, it is non-existent not only not had axial force but also do not had radial force, be that traditional method all is to select the existence that the corresponding axial force of thrust bearing is installed for use and can not alleviate in the prior art, more can not eliminate, the spiral mud extrusion machine that uses of brick and tile enterprise for example, the corn-popping machine of grain processing plant and middle-size and small-size rice milling machine, the spiral lodicules of marine communication means afterbody etc. on-streamly all exist bigger axial force.Such as the on-stream lift angle of spiral mud extrusion machine (inclined-plane) pug is pushed away forward by helical blade, formed back pressure connects main shaft to pusher with the helical blade band, since behind the main shaft position have the existence of thrust bearing make its retreat become impossible, otherwise just can not run well, but decide circle and the moving-coil of ball in the on-stream thrust bearing and front and back paste to such an extent that tightly tighten and rapid friction take place, according to the size that how much determines the friction degree of back pressure, and this friction must be to consume certain energy as cost.The traffic tool waterborne (ship) are too: the propeller in the running with water toward pusher, it is backward going that formed back pressure connects with the propeller band that main shaft and whole ship push away forward, if there is not the existence of thrust bearing, propeller and main shaft will break away from frame (installation place), and ship also just can not navigate by water.

Summary of the invention the utility model discloses a kind of a kind of device that not only thrust bearing need not be installed but also can run well, aim to provide a kind of simple in structure, cheap, a kind of indirect drive machinery steady, that energy and labour saving also can drive two or two above machine runs simultaneously that turns round, be achieved by the following technical solutions.

A, utilization symmetry are offset back pressure

Meta on the horizontal live axle that is driven by power (do not get rid of under special circumstances live axle is changed into by level vertical or tilt) is installed one and is revolved the helical blades that rise each other in the other direction by four and form a drive plate jointly, and on the circumference edge portion of the side faces at both ends same straight line about relatively, rectangular each slide bar with drive plate φ is installed respectively in the drive plate left and right sides, relatively two be one group only lack two groups be two of each sides totally four slide bars with level and equidistant arrangement, the slide bar tail end pastes mutually with drive plate, its front end is spaced apart to be equipped with its axis centre becomes 90 ° of right angles with live axle high speed shaft, top, high speed shaft two is separately installed with each eccentric wheel disc, according to the center summary height of the eccentric wheel disc of sense of rotation or the slide bar of installing a little less than level, the plane, outside of each eccentric wheel disc is near non-central each the little bearing that is equipped with of periphery, the orientation of little bearing on axis on two eccentric wheel discs is staggered mutually 180 °, with connnecting rod big end and microcephaly (two ends) is the slip fit with the mutual Colaesce of little bearing on top end of sliding rod and the eccentric wheel disc respectively, and its Colaesce mode is just like using connecting rod Colaesce bent axle and piston in the internal-combustion engine.Drive plate is on-stream because the existence of its spiral lifting gradient of helical blade, to only lack in 1/2nd weeks of every rotation two groups totally four slide bars at one time in two one of wherein every side row after that moves ahead, whenever rotate a circle to come and go before and after every slide bar and slide one back and forth, drive same high speed shaft thus and ceaselessly rotate and do work.Eccentric wheel disc role is a principal element that forms inertial force except driving the high speed shaft running, otherwise using eccentric disk or eccentric rod instead, to replace eccentric wheel disc also be feasible.

In slide front and back, drive high speed shaft rotation by slide bar and be about to straight line motion and become the method that rotatablely moves and have multiplely, by the eccentric wheel disc of connecting rod Colaesce, high speed shaft can be made bent axle, equally by connecting rod Colaesce transmission except that above-mentioned; A kind of the most reliable the simplest method is at the slide bar front end tooth bar to be installed, and at the corresponding position of high speed shaft corresponding half gear is installed simultaneously, its superiority has three: one, saves the slide member that is connected on connecting rod and top, connecting rod two, thus economization the shared position of connecting rod make machinery become compacter; The 2nd, turn to surely easily, promptly the high speed shaft band is connected half gear and be arranged at going up of tooth bar or following, left or the right left-handed or dextrorotation of selecting high speed shaft according to technological requirement; Three is tops, two ends that half gear needn't kine bias heart wheel disc must be installed in high speed shaft like that, otherwise connecting rod just can not pass through, thereby high speed shaft suitably can be lengthened where necessary and be more convenient for the setting of power train, such as shifting out certain size by the machine of the on-stream drive of high speed shaft.

When selecting the rack pinion engagement driving for use, because it is that null is promptly thrown off with half gear that the slide bar band connects the tooth bar return, thereby unlike eccentric wheel, in rotation, impel the slide bar return, the way that solves is at the afterbody of slide bar or the middle return spring of installing, its spring is compressed in moving ahead, its drive plate spiral gradient was become to descend to making by rising and causes the tractional force compressed spring that disappears and obtain immediately to loosen and stretch when stop transferred the back row to before current line arrived, and impelled row behind the slide bar thus.When moving ahead according to the size of spring force drive plate is applied certain resistance, apply certain thrust during the row of back, resistance and thrust drop on simultaneously to be cancelled out each other on the same drive plate and equal zero by having to become not have.

In order to alleviate that the hard grind of rack and pinion in engagement running wipe is slide relative and because of must the annotate trouble of lubricant oil of friction, and replace the tooth of rack and pinion with little bearing, a bearing can support a plurality of teeth, the running middle rack for initiatively, gear be passive, one bearing initial overlap joint engagement in back is as the criterion before last bearing is about to throw off, the big bearing of gear is corresponding big, otherwise then little.Thereby slide bar in moving ahead half gear on its front tooth bar and the high speed shaft or each bearing each other fit drive the high speed shaft rotation, thereby half does not promptly have little bearing tooth bar and the disengagement of half gear for blank to slide bar owing to half gear circumference in the row of back, the slide bar return is the i.e. on-load not of null thus, but do not hinder high speed shaft to remain in operation, reason be its installation position of little bearing on each gear of high speed shaft two ends and tooth bar corresponding part on axis, be staggered mutually 180 ° promptly one the first from left right or say one last one down, the double joint slide bar one in front and one in back successively meshes with each one and half gear respectively and throws off for taking turns in round sliding, promptly another initial engagement that enters in throwing off drives same high speed shaft thus and ceaselessly turns round.Details are as follows with the acting principle for its structure:

Per two each other in the other direction promptly one be a full circle for a left-handed blade that has a lead angle around axle half cycle (semicircle) for the dextrorotation mutual group that is connected together, four blades are that four semicircles are formed two full circle and are centered around middle somewhere on the same axis with helical in the other direction respectively and are combined into a metal driving dish (generally machine all is that metal is done, down together), two somewheres of full circle on axis (vertically) each other for be close to mutually or from recently, be separated by 180 ° (360 ° of ÷ 2 in transverse section of axle) from getting farthest, see from the side as a splayed shape or herringbone center and gone here and there on axle, deduct vertical minimum distance with vertical (axis) maximum distance of live axle and just equal the journey of walking that slides before and after the slide bar divided by the merchant of 2 gained again, equal the lead angle size that two half helical blades are combined as a full circle in other words; The outer φ size of each full circle blade deducts φ in it (axle φ) size and equals the width of blade again divided by 2 its results, its thickness is fixed according to the stress in acting promptly to be as the criterion can not be out of shape because of back pressure. and the slide bar of same size is walked its helical blade of journey φ big more the two relation of being inversely proportional to of minor spiral lift angle more, lift angle is crossed stool and is meaned that on-stream radial force is big and be unfavorable for laborsaving and energy-conservation. the circumference left and right edges of drive plate with about the slide bar tail end of relative two levels installations each other for being close to, as long as two about the slide bar radical of institute's fit can be divided exactly promptly relatively with 4 on a horizontal linear are one group and only lack 4 slide bars of two combinations, two groups 4 or four groups 8 or six groups 12 is that unit is equidistant arrangement at the drive plate circumference by that analogy with the group, the live axle that is driven by power connects and the every running two of drive plate/once can impel in week organize slide bar at one time in half half back row that moves ahead, every fortune circles, and round before and after each root slide bar to slide that promptly does work back and forth moves ahead be by the on-stream driving of drive plate---relative about two slide bar tail ends in passing, slide from the minimum range to ultimate range and promptly leave mutually for running in the opposite direction each other with the lead angle level that rises forward; The back trade when selecting the rack pinion transmission for use be rely on move ahead in compressed spring resetted by the stretching, extension elastic force after loosening---relatively about two slide bar tail ends the back row is close mutually by head-on coming up each other from ultimate range to the minimum range in the other direction with lead angle. owing to drive plate is made up of the helical blade that has lead angle and is installed on the horizontal live axle, its blade plane and live axle meet at right angles on length, thus its lift angle be the lifting on slope be of a size of towards about rather than up and down, 360 ° of half half declines of rising of circumference, half retreats (descending) to rise (upward slope) before half in other words, relatively the left and right sides is the same, and two groups or many groups can be with the 4 many slide bars of dividing exactly half half back row and doing work of moving ahead wherein about can driving simultaneously according to the single drive plate of φ size of technological requirement and drive plate is on-stream thus.

In order to reduce on-stream slide relative friction, the one, with drive plate mutually the slide bar tail end of subsides place a bearing of fitting mutually in whole circumference and drive plate both sides or title travelling wheel are installed, drive plate is passive for the active travelling wheel in the running, repeat to slide before and after in rotating synchronously, impelling slide bar straight line and original position each other, be a disk that has lead angle only because of helical blade, on-stream from the axle center its linear speed far away more fast more, produce certain slide relative friction in order to overcome the on-stream speed difference that becomes because of brachmorphy in the helical planes contour foreign minister with slide bar tail end travelling wheel, promptly make the plane inclined-plane of certain taper into according to the width of travelling wheel, and travelling wheel is also made the little taper of outer imperial palace with the difference of the interior outer peripheral lines of pasting the position mutually; The 2nd, frame separated by a distance is installed and can be slided synchronously and two groups of rollers that rotate with slide bar at two places, front and back of slide bar, every group only lack two be installed on slide bar about or up and down slide bar is gripped in wherein as the location, slide bar is passive one fast neat fast one very little for buffing wiping resistance slowly together slowly for the active roller in the slippage.

Common two slide bars that drive same high speed shaft running are that a row is installed in to drive and faces left or must stagger 180 ° mutually in right same side, step back in turn to last and to repeat for interior at one time one in the running, when the many groups of installation slide bar, (two that are positioned on the same straight line in the drive plate left and right sides is one group to two slide bars in a left side and right relative each row, being positioned at face first is a row with relative per two of drive plate φ) with the mounting type of high speed shaft level is arranged, the branch of vertical and inclination, wherein fully level and vertical fully can only be respectively to be single, perhaps single all do not have, and tilt according to what of the difference of gradient and institute installation group number can be doublely to become to arrange more, yet no matter its position is in level, vertical or its acting principle that tilts is constant.With twinned each row is that unit adjusts its length dimension and is about to its lengthening or shortens, make the high speed shaft installation position that the branch of individual front and back is arranged thus, thereby the plurality of rows slide bar that is in same side can drive the running of some high speed shafts simultaneously, and promptly every high speed shaft is one to come and one in front and one in back slide middle driving by each slide bar of two.

B, by magnet repulsion in order to eliminate frictional resistance

After the slide bar tail end is installed travelling wheel to frictional resistance can only be reduce and can not completely without.In order further to eliminate its frictional resistance it is not had by having to become, inhale the magnetic principles that the same sex (utmost point) is repelled each other mutually according to the magnet opposite sex (utmost point), paste the position mutually with the slide bar tail end and the slide bar tail end is installed the magnet that the same sex is repelled each other respectively in its helical blade circumferential plane of drive plate, choose the volume of magnet according to the size of required driving force, it is that drive plate and slide bar tail end are changed into by being close to state mutually that to be spaced from each other slight distance be the on-stream relative friction that do not take place that the same sex is repelled the direct effect that is play mutually, and the indirectly-acting that is risen is to increase its output power (driving force).The power of repelling each other by the same sex of magnet in the running rises with lead angle, and relative two slide bars slide before the first from left dextrad in the other direction to run in the opposite direction about passing, no matter move ahead or back Xingqi slide bar tail end can not be adjacent to drive plate, thereby be implemented in eliminated under the condition that driving force is growing on and on drive plate on-stream with the slide bar tail end because of being close to the frictional resistance that forms mutually, the result of Dao Chuing equals drive plate to implement acting under the state of idle running thus, and more do not adapt to high rotating speed operation because of there being friction, originally exist a spot of radial force also because of no frictional resistance greatly reduces thereby make, only remaining unloaded load is the energy consumption of machine when idle running.Because the suction of permanent magnetic iron and repulsion are objective reality, and without any need for the intervention of external force, the volume that needs only corresponding increasing magnet according to technological requirement makes that repulsion is corresponding to be increased, and just can obtain the corresponding increase of driving force.Its repulsion of magnet and the suction of reply certain volume all is that distance of living in is far and near between the two determines that its power is promptly near big and far smaller by first and second, therefore add its slight clearance as long as calculate the journey size of walking of good its slide bar, even also will not paste very tightly, thereby no longer need bearing or travelling wheel be installed at the slide bar tail end as having pressed close to.

The same sex of magnet (utmost point) is repelled each other---and the utilization manpower is close together the first and second two blocks of magnet, can separate separated by a distance for running in the opposite direction when stopping firmly (loosing one's grip) each other immediately automatically; There is a natural attraction between the sexes for magnet---and the first and second two blocks of magnet are in a certain distance apart from one another drawn close automatically to head-on coming up.Hence one can see that, the displacement of magnet only limits to spaced apart and competence exertion effect within certain distance, and this distance is very limited, slightly a little further just powerless, back out certain distance and reach by repulsion and be close to the back mutually and just can not moved again, in any case determined the magnetic that directly to use magnet to promote machine run thus by suction.

Just made a world of difference with the mode situation that the drive plate running combines by the power that the same sex of magnet is repelled each other, because the slide bar tail end does not paste mutually with drive plate, so the rotation of drive plate is to carry out under the state easily, by the formed driving force of magnet same sex phase mutual repulsion is to be based upon helical blade that drive plate utilization in the rotation has lead angle to pass on the basis that slide bar moves ahead, otherwise repulsion does not greatly play effect more yet; Drive plate very like a cork running promptly to equal or be slightly larger than the idle running energy consumption be to rely on the formed thrust of power that the magnet same sex repels each other to impel its circumference and slide bar tail end to become and separate little clearance and eliminated frictional resistance by being close to state, otherwise just be far from being easily, the two complements each other indispensable.

As long as long as can arrange down on its contour of corresponding site of two sides about the drive plate circumference, the slide bar row number of being installed be unrestricted, and the difference of single drive plate apparent volume size only can drive each machine run of two less simultaneously.And two relative slide bars of every side are that a row both can drive single machine, in case of necessity also can by two high speed shafts front and back are adjacent with belt of the dumb bell shaft that installs additional and taper change gear or belt wheel each other Colaesce play that the high speed shaft of cause more than two or two is common to drive same machine, because respectively organizing slide bar is driven by same drive plate, so determined that their rotating speeds each other all are absolute equating, provide a feasibility condition for uniting mutually.Per two slide bars of installing relatively are same high speed shaft running of the common drive of a row about same drive plate, when equidistant installation is arranged more, slide bar is the branch that there is length in unit with row, connect fit high speed shaft the branch of front and back is just arranged naturally, just can realize taking their own roads not disturbing mutually, install thereby can hold more machine.

General machine all is to be combined by former moving part, working portion and drive part.Former moving is the power resources (as motor or internal-combustion engine etc.) of machine; Working portion is to finish the purpose that the machine predetermined actions promptly will realize, its structural type depends on the purposes of machine itself; Drive part is the medium tache of the transmission of power of the motion of former moving part such as motor being given working portion.Parts such as the drive plate among the present invention, slide bar, high speed shaft and eccentric wheel disc all belong to transmission part.

When the high speed shaft of installing at one when above, because both there had been the branch of front and back each other in each root axle present position, the while exists does not again straightly promptly have angle identical two piece axles with equidistant installation at the left side or each high speed shaft of the right of same drive plate with the branch of inclination in 360 °.Determine each root high speed shaft when same machine of common drive, can not adopt the direct geared engagement driving thus, can not adopt the two high speed shaft associating transmissions that front and back are adjacent of sprocket wheel and chain.Can only be that one of them gear is installed on the indirect drive axle that installs additional, and 360 ° of the circumference up and down that the indirect drive axle is placed the other side somewhere and before and after being not wherein, because it is that angle is consistent that the indirect drive axle is respectively one with front and back two adjacent high speed shafts, one is the vertical plane unanimity, either one or the other, consistent chain-driven or band transmission, the consistent meshed transmission gear (angular wheel) of being convenient to of vertical plane be convenient to of angle; Perhaps according to the opening transmission in the setting angle of each root high speed shaft (level, vertical, tilt) the utilization belt transmission with intersect transmission and semidecussation transmission each high speed shaft united mutually.The two kinds of methods in front and back need only be used wherein, and a high speed shaft drive machine gets final product.The way that some high speed shafts drive same machine run is applicable on the traffic tool, just not have the necessity of uniting if be used for driving generator, because the platform number of the size of its drive plate and generator can not be subjected to the restriction of space and driving force in power generation operation.

In order not hinder the equidistant installation in position of many rows slide bar about drive plate, and two full circle helical blades that will have a lead angle removing certain size promptly keeps certain distance in the other direction to the left and right respectively, reserve in the middle of dead band be used to drive wheel is installed in case with power engine on the driving wheel Colaesce and transmission, the left and right sides that its positioning bearing is installed on drive wheel gets final product.

It is more simple and easy to do and the more laborsaving to be used for driving the operation of piston type suction pump by the straight line motion of slide bar, the suitablelyyest rather is used for pumped-storage power generation.

Beneficial effect of the present invention is summarized as follows:

According to Newton's third law " active force between the object is always mutual, and one is called firmly, and another is reaction force, their equal and opposite in directions, direction is opposite, and it acts on point-blank ".Reaction force is called " reaction force ", for example the small boat free-floating is on river surface, when a people jumps out of canoe when disembarkation from canoe, the people need utilize canoe to produce power and speed increment, according to principle of momentum conservation, canoe can obtain one with the people jump out of that its active force of canoe equates for reciprocal " reaction force " and speed to middle of the river direction drift away from the bank, its drift velocity and the drift size size of exerting oneself when jumping out of canoe is directly proportional.Many on-stream back pressures (axial force) that all can form of machine, the unique way of the reply of prior art is exactly to install thrust bearing additional in the position, middle back of main shaft to bear this power (reaction force), ball in the thrust bearing in the running is directly proportional with the size of back pressure with its frictional resistance of front and back back-up ring (moving-coil and Ding Quan), thus must be to consume certain energy as cost, although and there is no small back pressure in the present invention, it is just passable but need only a radial bearing respectively to be installed respectively at its two ends of live axle that drive plate is installed, necessity of thrust bearing is not installed, its reason is: the on-stream interior at one time past opposite direction of two slide bars that the right, a relative left side is on the same straight line of drive plate is passed, formed back pressure (axial force) equivalent and drop on the relative left and right sides of same drive plate simultaneously and cancelled out each other and become not have in passing by having, rather than by changeable few, remaining just on a small quantity by lead angle formed radial force of size and unloaded load, being implemented under the condition of labour-saving the slide bar that drives many a times thus slides and does work, to have goods its work efficiency under the condition of labour-saving but to be doubled be the same thing at having only one to choose one pair of load just like a people, and promptly conventional practice its input power under the condition that output power only doubles less has to subtract not have and increases relatively.
