Description
Technical field
The utility model relates to a kind of Vertical Vibrating driving wheel, particularly relates to a kind of Vertical Vibrating driving wheel of built-in changement, is applicable to road roller.
Background technology
Road roller is the compaction apparatus be made up of one or more round metal cylindricality roller or rubber tyre, and it can by the rolling of compaction apparatus and (or) vibration rock crushing, compacting soil, bituminous concrete or gravel.The mode of vibration that road roller market is most widely used is circular vibration, namely along the vibrator Periodic Rotating of vibrating wheels axis arranged, forms periodically centrifugal force.
The disturbance in the horizontal direction of circular vibration wheel can cause the stripping of surfacing, and vertical vibration horizontal vibration displacement is in theory zero, is conducive to the compaction quality improving laying surface.For circular vibration, vibrating wheels is due to the interference in the horizontal direction of its centrifugal force, the core wheel track of vibrating wheels is a complicated circular motion, due to the impact of ground resistance in the horizontal direction, the swing of vibrating wheels in horizontal plane will be caused, when machine travels, this horizontal disturbance will affect the stability of straight-line travelling.Vertical Vibrating driving wheel does not have the interference of horizontal vibration power, and the track of its core wheel is the straight line of a vertical ground all the time, can not cause vibrating wheels swing in the horizontal direction, this guarantees riding stability.In a word, the relative circular vibration of vertical vibration has plurality of advantages, but Vertical Vibrating driving wheel is due to its complex structure, and the reason that reliability is low fails extensively to be promoted.
Current industry also there is the improvement project about vertical vibration wheel, typical in patent " a kind of directional vibration wheel of road roller " (ZL201110145520.8), by left avertence axle, middle eccentric shaft is arranged in the housing of left exciting room, left vibrator housing is directly assemblied in steel wheel housing, right avertence axle is arranged in the housing of right exciting room, right vibrator housing is assemblied in vibration and exports in bearing, left avertence axle, the centrifugal force that middle eccentric shaft produces can be directly passed to steel wheel housing by left vibrator housing, the centrifugal force that right avertence axle produces passes to steel wheel housing by vibrating output bearing, gear-box to be positioned in right vibrating shaft bearing and to be arranged on the end of right vibrator housing.Such vibration exports the centrifugal force that bearing only needs to bear the generation of right avertence axle, " structure, significantly reduce the load exporting bearing, and decrease the quantity that vibration exports bearing, and make vibrating wheels structure be tending towards simple ".
But, first such scheme have ignored assembly difficulty, left avertence axle, middle eccentric shaft, four vibration bearings and four left vibrating shaft bearings are first assemblied in left vibrator housing, assembly again luggage fits in steel wheel housing, the large difficult point that assembly is heavier when being vibrating wheels dismounting, is so just unfavorable for assembling and field maintenance.In like manner, also there is this problem in right vibrator housing unit, and " gear housing to be positioned in right vibrating shaft bearing and to be arranged on the end of right vibrator housing ", make whole assembly heavier, site assembly maintenance becomes more difficult.Secondly, the centrifugal force produced when in fact left avertence axle and middle eccentric shaft rotate, also needs by the transmission of left vibrating shaft bearing, in like manner right avertence axle rotates the centrifugal force produced also needs by the transmission of right vibration axle bed, so, centrifugal force transfer route is complicated, causes overall structure reliability low.Moreover this patent wants the carrying by reducing vibration output bearing, improves the life-span that vibration exports bearing, but the vibration output bearing improved just reduces carrying, does not fundamentally solve the use problem that vibration exports bearing.
In sum, need research and development badly and improve out a kind of road roller Vertical Vibrating driving wheel new structure.
