Description
Technical field
The invention belongs to equipment for treating materials technical field, particularly to a kind of variator, stirring or the cutting of different material can be applied to according to the difference of variator material and size.
Background technology
With the requirement also more and more higher needing material variety to be processed to get more and more to material process in productive life.The distribution between overall flow and turbulence pulsation all has an impact to power of agitator for the type of agitator, size and rotating speed, for different dynamic viscosities between different material it is also desirable to give different rotating speeds thus realizing being sufficiently stirred for.In addition, requiring it is also desirable to processor has speed changing function for adapting to the different disposal to different material.
Taking food preparation as a example, the functional requirement more and more higher to agitator for the market, this requires the outfan of agitator（Be usually blade, cutterhead, stirring rod, stirring sheet etc. have cut or agitating function moving component）Working speed adjustable in the larger context.For example, generally require the rotating speed of blade when being shredded/being ground with blade at 10,000 revs/min about or higher；Then need rotating speed hundreds of to 1,000 revs/min when with cutterhead shredding or section；And when being kneaded dough with stirring rod or cooking soup, then require rotating speed at tens to one or two hundred rev/min.Product in the market can be roughly divided into three kinds：The first is that have motor direct-drive workpiece, and so its gear ratio is 1:1；Second is that workpiece to be driven by gear or belt etc. by motor, and its gear ratio is single fixation；The third is the drive mechanism arranging two groups or more different drive ratios between motor and workpiece, and every group of drive mechanism has its fixing outfan, is coordinated with different outfans by changing different adnexaes, to realize the change of gear ratio.
Two extreme working conditions of agitator are analyzed caning be found that, workpiece is required to have very high rotating speed in chopping/grinding, generally require the rotating speed of blade at 10,000 revs/min about or higher, but it is now then very low to the torque requiremnt of blade, even if motor slows down without any drive disk assembly（Increase outputting torsion）, also can realize chopping/grinding work well.But when kneading dough it is necessary to outfan has very big torsion, and rotating speed only needs to tens rpms and is sufficient to.General cooking machine is because the torsion required for being unable to reach; function of kneading dough cannot be realized, if user takes such machine to knead dough it will usually make rapid rising of motor temperature burn out machine at all; if the automatic safety device design of machine is not enough, it is possible that it is even on fire with spark to smolder.And the cooking machine of low speed often can only carry out kneading dough the slow-revving work of needs of this class it is impossible to complete to shred or grind the work of a class.
Existing product typically has fixing gear ratio, realize the working speed of outfan by adjusting the rotating speed of motor, some mid- to high-end products also can increase the closed control circuit to motor rotary speed thus more accurately controlling rotating speed in required scope, and the regulation adjusting actually to its input voltage of motor rotary speed.It is known that, motor (mostly series machine or direct current generator) its design speed that generally agitator is used is all thousand of to up to ten thousand revs/min, when needing slow-revving, need to turn down the input voltage of motor, the outputting torsion of motor so will certainly be made to substantially reduce.The work that conventional motor at all cannot be stable under tens rpms of speed in the market, even if using closed control circuit, also cannot allow motor also stablize enough torsion output under so low rotating speed.So the product of this fixed drive ratio is all attended to one thing and lose sight of another, it is difficult to accomplish that the work of high and low rotating speed makes the best of both worlds.
Relatively advanced in the market is the third product in above-mentioned example, but the wretched insufficiency that this product exists is exactly to need to change the change that different adnexaes just enable gear ratio, and user to change attachment in use be pretty troublesome thing.Such as food materials are first shredded at a high speed by certain recipe, and in stirring at low speed heating, user needs to empty the food in similar for jar Work container and could change adnexa, then again the food materials just now shredding is reinstalled container.
Content of the invention
It is an object of the invention to provide a kind of variator, can according to difference in functionality need change gear ratio, take into account the big torsion of the slow-speed of revolution and two working conditions of the little torsion of high rotating speed, gearshift can be realized simultaneously in motor process and rotate it is not necessary to stop variator for conversion work state.
The present invention be employed technical scheme comprise that by its technical problem of solution：
A kind of variator, including change speed gear box and gearshift, described change speed gear box includes housing, is provided with planet carrier, planetary gear, sun gear and slip gear ring in housing, and slip gear ring is connected with gearshift, and being capable of axially-movable under the drive of gearshift.Variator realizes gearshift by the axially-movable of slip gear ring.

Due to require the working speed of blade or similar workpiece from tens go to up to ten thousand turns adjustable, be low rotation speed large torque and the little moment of torsion of high rotating speed under two extremities, the drive mechanism of single fixed drive ratio can only be attended to one thing and lose sight of another.When gear ratio is relatively low, high-revolving working condition can be met, reach preferable chopping result, but during the slow-speed of revolution, torsion but cannot meet requirement；When gear ratio is higher then conversely, the high pulling torque output during slow-speed of revolution can be met, but it is unable to reach the required high rotating speed of chopping.The gear ratio of agitator proposed by the present invention can be according to the difference automatic switchover of user's selection function.Adopt big speed ratio during low speed, increase torsion, during high speed, adopt close steps, improve rotating speed, take into account low rotation speed large torque and two extremities of the little moment of torsion of high rotating speed such that it is able to make the best of both worlds.
Can work in the per minute tens rotating speed intervals arriving up to ten thousand turns for realizing blade or similar workpiece, the variator of one transmission ratio-variable is set between motor and working end, when user selects different functions, control circuit can automatically switch to suitable gear according to program setting, thus obtaining optimal power output.For example：When needing high rotating speed chopping, variator is switched to the gear of underneath drive ratio, obtains higher rotating speed；When needing low-speed big work, such as knead dough, variator is switched to high transmission ratio gear, reduce and while output speed, improve outputting torsion.When switching gear ratio, user does not need to change any adnexa in this embodiment it is not even necessary to shut down, and can directly shift to run up in the slow-speed of revolution runs, or directly shift to low-speed running in high rotating speed runs.Do drivewheel in sun gear, ring gear is fixed, planet carrier output when, variator is in big speed ratio state；When sun gear, ring gear, planet carrier three are fixed as one, variator switches to close steps state.

Other technical characteristics are identical with embodiment one.
The operation principle of the present embodiment is as follows：
One operation principle in conjunction with the embodiments, the present embodiment has made improvement to it, replaces fixing tooth 101, slide teeth 601 and turning gear 801 using fixed stop face 102, slip stop surface 602, pivot stop face 802.By gear arm 10, slip gear ring 6 is pressed on fixed stop face 102 or pivot stop face 802, frictional force is increased by pressurization, so that slip gear ring 6 is static with respect to fixed stop face 102 or pivot stop face 802.
As shown in figure 4, during low or first gear, slip gear ring 6 moves toward the direction away from sun gear 8, its internal tooth and planetary gear 4 engage, and the fixed stop face 102 on slip stop surface 802 and housing 1 compresses, and slip gear ring 6 is all axially and radially to be fixed to move.
As shown in Figure 5, during top gear, slip gear ring 6 moves toward near the direction of sun gear 8, fixed stop face 102 on its slip stop surface 802 and housing 1 departs from, internal tooth is engaged with planetary gear 4, pivot stop face 802 on slip stop surface 802 and sun gear 8 compresses, and now sun gear 8 and planetary gear 4 locking are integrated by slip gear ring 6, and three rotates only as Integral synchronous.
The beneficial effect of the present embodiment is, not only do not need during gearshift to stop variator, also be not in situation about can not shift gears because of gear teeth pairing, high speed gear can freely be shifted gears to low gear or low gear to high speed gear, reduce the abrasion between gear, rubber-stopper face easily produces and changes, and cost is little, easy to use.
It is below the gear ratio under the design different working condition：
Hereinafter it is used for the rotating speed of each gear and gear ratio state during food processor for the design：(only making example, can adjust according to practical situation in practical application)
The power resources of the multifunctional food processor in this example are the series excited machines that a highest working speed is 20000rpm, coordinate closed control circuit (as Hall element or Grating examinations motor rotary speed) to detect and to control motor rotary speed.Working outputs arrange 10 operation range altogether, this 10 output gears are divided into two intervals, correspond to change speed gear box respectively and be in high speed and low speed two states, control circuit can be according to the gear of the different switching change speed gear boxes of user's selected gear, when working in same interval, change speed gear box is not shifted gears, and only when transregional gearshift of user, change speed gear box just can gear shift.
Can be seen that when 1 grade by form above, the output speed of working end is 60rpm, without change speed gear box, common series excited machine or direct current generator at all cannot steady operations under such slow-speed of revolution again.The reducing gear being 9.2 because of gear ratio in this example, the working speed of motor brings up to 552rpm, amplifies motor torque simultaneously and reaches as many as 9 times, and such motor not only can steady operation, and outfan has enough torsion, it is easily accomplished as stirred face such high capacity work.
When 10 grades, the output speed of working end is 8500rpm, and resultant gear ratio is switched to 2.3, motor rotary speed 19550rpm, is mainly used in shredding or mixes this high-revolving work of class needs.
Thus fully demonstrate variable gear ratio effect in actual applications so that machine can take into account two kinds of extreme working conditions of low rotation speed large torque and the little moment of torsion of high rotating speed.
