Background technology is present, and the consolidation effect on roadbed and road surface is the key factor that influences construction quality in the road construction, and the compaction quality requirement is more and more higher, and this just has higher requirement for construction machinery.In numerous compacting machinaries, the vibratory compaction of vibratory roller is to use maximum debulking methods in the present road construction, and for satisfying different compacting requirements and adapting to the diversified desirability of shop layer, the adjustable of road roller amplitude seems extremely important.The vibration of vibratory roller is produced by the centrifugal action that produces that runs up of eccentric block, the theoretical amplitude of vibratory roller equals the weight of eccentric moment than last vibrating wheels, the quality of vibrating wheels can not arbitrarily change in vibratory roller, so, have only by quality that changes eccentric block or the purpose that eccentric moment reaches amplitude modulation.The vibratory roller amplitude governor motion of prior art, the involving vibrations wheel, establish small vibration axle, interior male splined shaft, left shaft holder and right bearing seat in the vibrating wheels, the small vibration axle is installed on the bearing of left shaft holder and right bearing seat inside, and right-hand member has an amplitude modulation spline housing; Male splined shaft is installed on the bearing of left shaft holder outside in said.There are following two problems in the amplitude governor motion of this structural vibrations road roller: the one, and most vibratory rollers can only be realized the adjusting of two amplitudes or an amplitude, many amplitudes that can not better meet different compacting requirements are regulated needs; The 2nd, well combination of frequency and amplitude modulation.
The summary of the invention the purpose of this utility model provides a kind of frequency and amplitude modulation in conjunction with many amplitudes of vibratory roller governor motion good, that many amplitudes that can satisfy different compacting requirements are regulated needs, to overcome the deficiencies in the prior art.
To achieve these goals, many amplitudes of the utility model vibratory roller governor motion, be to improve realization on the basis of existing technology, its involving vibrations wheel, establish small vibration axle, interior male splined shaft, left shaft holder, right bearing seat in the vibrating wheels, the small vibration axle is installed on the bearing of left shaft holder and right bearing seat inside, and right-hand member has an amplitude modulation spline housing, and interior male splined shaft is installed on the bearing of left shaft holder outside; Its main points are small vibration axle peripheral hardware large eccentricity axles, form total eccentric shaft; Left shaft holder is connected with the large eccentricity axle by bolt with the right bearing seat, and two ends are by bearings; Said amplitude modulation spline housing is provided with inside and outside spline, the right-hand member external splines engagement on internal spline and the small vibration axle, the internal spline engagement on external splines and the right bearing seat.
In order accurately to regulate the amplitude that varies in size, an amplitude modulation dish is installed in the outer end of said amplitude modulation spline housing, is provided with 18 scales above the amplitude modulation dish, and the phase angle of every adjacent two scales is 20 °, in the bottom, right side of right bearing seat an indicating arm is installed.
The utility model compared with prior art has the structure design novelty, can realize the adjusting of a plurality of amplitudes, can satisfy different compacting needs, better realizes combining of amplitude and frequency, can increase substantially compaction capacity and consolidation effect.
