The specific embodiment
The utility model vibratory roller, comprise frame, frame is provided with driver's cabin, motor, drive disk assembly, functional unit, wheel and at least one muller, be characterized in, also comprise having direction of vibration and the stepless adjustable directional vibration mechanism of vertical vibration energy, this directional vibration mechanism is provided with on a muller at least.
See also accompanying drawing 1.This vibrating mechanism is made up of inside and outside eccentric block eccentric stiffener of forming and the planetary gears that drives inside and outside eccentric block rotation.Eccentric block 2 in being equipped with on power transmission shaft 1 includes sleeve 3 outside interior eccentric block, outer eccentric block 4 is installed on it.Power transmission shaft 1 is bearing on the sleeve 3 by bearing, and sleeve 3 itself is bearing on the side plate 22 of road roller muller 5 by bearing, and muller is bearing on the reducer junction plate 21 by the spindle nose at sleeve two ends, and links to each other with frame 7 by rubber shock absorber 6.Inside and outside eccentric block is realized the synchronous backward rotation by the planetary gears of a two-freedom, and it is made up of two planet row I, II and a pair of worm-drive pair.Planetary mechanism is driven by the hydraulic motor 8 that is installed in power transmission shaft 1 end.Its power is after entering planetary mechanism, one the tunnel directly passes to interior eccentric block driving by power transmission shaft 1, and it rotates (for example clockwise direction) to a certain direction, another road then sun gear 9 by being fixed on the planet row I of axle on 1 in the key connecting mode and the planetary gear 10 that is meshed with it passes on the shared gear ring 11 of two planets rows, arrange the planetary gear 12 of II then by the planet that is meshed with it, and carrier gear 13 finally passes to the sun gear 14 that connects mutually with outer eccentric block sleeve 3, and drives outer eccentric block 4 to the direction rotation (for example counter clockwise direction) opposite with interior eccentric block 2.The gear ring 11 of planet row I and planet row II is identical with the gearratio of sun gear 9 and 14, just planet row II how a carrier gear 13 (asking for an interview Fig. 2).This drive mechanism has guaranteed that inside and outside eccentric block can be with identical rotating speed reverse sync rotation.Because the planet carrier 15 of planet row II is cemented on the planetary gear tank shell 16, thereby planet row I is actually fixed shaft wheel system.The planet carrier 17 of planet row I is cemented on the worm gear 18, can freely rotate relative to housing 16, thereby planet row II has two degree of freedom.Worm gear 18 and worm screw 19 are high self-locking performance transmissions that a pair of helical angle is very little, gearratio is very big, and worm screw 19 then drives (asking for an interview Fig. 3) by stepper motor 20.When stepper motor rotates a certain angle, thereby worm gear 18 that is planet carrier 17 also will rotate a small corner thereupon.This corner will reach on the sun gear 14 by planetary gear 10, ring gear 11, planetary gear 12, carrier gear 13, make it relative sun gear 9 and turn over a certain additional rotation angle, even produce a relative rotation between the also inside and outside eccentric block, thereby make the synthetic centrifugal force of two eccentric mass and vertical direction form a certain angle, to reach the purpose that changes the directional vibration direction.
The principle that changes the directional vibration direction can obtain further instruction from Fig. 4.This figure is the overlapping in vertical direction situation of inside and outside eccentric block.As can be seen from FIG., when inside and outside eccentric block is in overlap condition in vertical direction (a-I among Fig. 4), both centrifugal force is stack vertically upward and each other, thereby synthetic centrifugal force is maximum.Be designed to be equal to each other as eccentric mass square, i.e. m with inside and outside eccentric block

2=A, then He Cheng centrifugal force Q

2(ω is the rotating speed of eccentric mass).When inside and outside eccentric block turns over 45 ° separately round about (a-II among Fig. 4), both superpose by component in vertical direction each other, then cancel each other out in the horizontal direction, thereby synthetic centrifugal force still equal Q for size vertically upward
MaxCos45 °.When inside and outside eccentric block turns over 90 ° separately round about (a-III among Fig. 4), both component in vertical direction are zero, and it is maximum that component in the horizontal direction then reaches, but still cancel each other out, and this moment, synthetic centrifugal force was zero.When inside and outside eccentric block turns over 135 ° separately round about (a-IV among Fig. 4), both still cancel out each other by component in the horizontal direction, and its synthetic centrifugal force then becomes vertically downward.When inside and outside eccentric block turns over 180 ° separately round about (a-V among Fig. 4), synthetic centrifugal force then reaches the maximum value of its negative sense for numerical value vertically downward, that is equals-2A ω
2Among Fig. 4 among the a-VI to Fig. 4 a-X shown that the synthetic centrifugal force of inside and outside eccentric block vertically fades to the peaked process of forward from maximum negative value.Can see that from the above description when inside and outside eccentric block was overlapped in vertical direction, it was a kind of directional vibration in vertical direction that their synchronous backward rotates caused oscillating movement.As by stepper motor 20 the internal mutually eccentric block of outer eccentric block being rotated a φ angle, then the direction of directional vibration will change.B is the outer eccentric block internal situation during eccentric block additional rotation φ=90 ° mutually among Fig. 4.B-I has shown the state when interior eccentric block is in vertical position among Fig. 4, the component of inside and outside eccentric block this moment on φ/2=45 ° direction will superpose each other, with the normal of φ/2 directions on component then cancel out each other, thereby its synthetic centrifugal force will be along the directive effect of φ/2 on muller.From all the other each positions of Fig. 4 b, can see, do at inside and outside eccentric block on any position of synchronous backward rotation, their centrifugal force all the time along with the direction line effect of vertical direction folder φ/2 jiao, its size then changes by the rule of simple harmonic motion.Therefore, this motion remains a kind of oscillating movement of orientation, and just its direction of vibration and vertical line accompany the angle of φ/2.Fig. 4 c has then shown when giving inside and outside eccentric block with 180 ° additional rotation angle, their reverse sync rotary course.Can see that from each position of Fig. 4 c the centrifugal force component in vertical direction of inside and outside eccentric block cancels out each other, then effect all the time is in the horizontal direction for its synthetic centrifugal force.From above explanation, can reach a conclusion: the direction of directional vibration is changed arbitrarily at vertical direction to work between the horizontal direction.
Ring gear of the present utility model by needle roller bearing support on housing.The support pattern of ring gear also can be considered to be bearing in three schemes (Fig. 5) on the planetary gear by the mode of floating.
The utility model has the advantages that:
(1) eccentric stiffener has only an inclined to one side cover axle of being made up of inside and outside eccentric block, and structure is very simple;
(2) can change the direction of directional vibration by the relative position that changes inside and outside eccentric block, thus the vertical vibration energy of step-less adjustment input soil easily;
(3) vertical vibration of the direction that can make directional vibration by Stepping Motor Control in compacting process when compacting begins progressively changes compacting horizontal vibration at the end into, can increase vibrational energy when compacting is loosened the soil with efficient that improves compacting and the pine that shakes that prevents skin-material by increasing amplitude so on the one hand, the vibration wave of horizontal vibration generation will be propagated in skin-material on the other hand, can also apply an additional compaction to skin-material, thereby make the top layer reach very high compactness.
