Description
Technical field
The present invention relates to engineering machinery field, in particular to a kind of road roller.
Background technology
Vibratory roller is the eccentric moment produced by the eccentric block of the High Rotation Speed in roller, excites roller mechanical oscillation, thus realizes the compacting to packing material.The vibration frequency of General Oscillation roller drum is not from tens hertz to more than 70 hertz etc.Mechanical oscillation are at this frequency separation, and human body can not contact, and therefore just had the vibration isolation system between roller (hereinafter referred to as vibrating wheels) and vehicle frame, i.e. shock mitigation system.
At present, shock mitigation system used in industry is with damping rubber block, in order to connect vibrating wheels and vehicle frame.
In the prior art, as shown in Figure 1, in order to the comfortableness in life-span and driver of ensureing component of machine, wish that again the exciting force of vibratory roller is enough large, adopt damper 2 vibrating wheels 3 and vehicle frame 1 spaced-apart, reduce with this vibration that vibrating wheels passes to vehicle frame.
Fig. 2 and Fig. 3 is the structural representation of damper 2, and wherein, 4 is outer brace, and 5 is connecting bolt, and 6 is shock reducing structure, and 7 is interior brace.Outer brace 4, connecting bolt 5 and interior brace 7 are an entirety by shock reducing structure 6 gummed.
As shown in Figure 1, in the left-half of this figure, vibrating wheels is connected by damper with vehicle frame, and from the vibrating wheels figure, left end is vibration end, is connected on vibrating shaft and produces vibration, then by damper damping, be then connected in frame by vibrating motor; At the right half part of Fig. 1, right-hand member is the drive end of steel wheel, and CD-ROM drive motor is connected damper with reductor, and driving force acts on damper, and drive the vibrating wheels be connected with it to rotate, the vibration of damper to vibrating wheels plays reduction and filtration.
Vibratory roller except relying on the exciting force of vibrating wheels and ensureing the consolidation effect of material, but mainly still will lean on the Gravitative Loads of complete machine on material, could obtain enough exciting forces.As how no matter a pile foam vibrate, it can not produce any compaction force.General vibratory roller, as the vibratory roller of 20 tons of weights, a weight accounting about about 1/3rd of its vibrating wheels, namely less than 7 tons, its most of weight is on vehicle frame.
Visible, connect the damper of vibrating wheels and vehicle frame, need to bear the quite most weight of vehicle frame, so damper is when bearing various service load, need all the time one on to the support frame active force of conducting oneself with dignity.Under road roller stopped status; damper just plays support and connection effect substantially, and its cross section mainly contains a sizable shearing moment, this moment makes damper shear strain; in the course of time produce plastic deformation afterwards, make defective shock absorber or direct shearing fracture.
Therefore, this shearing moment accelerates the inefficacy process of damper greatly, reduces its application life, and damper is vibratory roller key components and parts, and its value is high, and replacement cost is large.

Shock-damping structure in road roller in the application is different from the shock-damping structure of existing vibratory roller, be characterized in by a kind of special damper 30, Fig. 4 and Fig. 5 is the scheme of installation of the damper in the present embodiment, change traditional damper connected mode, the force-bearing situation of thorough change damper, improve the damping effect of vibratory roller, improve the reliability of shock mitigation system, greatly extend the application life of damper.
As shown in Figure 4 and Figure 5: the shock-damping structure of the road roller in the present embodiment is primarily of compositions such as damper 30 and screws.The left end of Fig. 4 is vibration end, and the second vibration end support 50 is connected with roller 20 by bearing, and the first vibration end support 40 is fixedly connected with vibration end vehicle frame 11, and the first vibration end support 40 is connected with damper 30 by screw with the second vibration end support 50.
Fig. 4 right-hand member is drive end, and the second drive end support 70 is integrated with roller 20, and the first drive end support 60 is connected with reductor 100; Reductor 100 is connected with drive end vehicle frame 12 by reductor support 110, and the second drive end support 70 is connected with damper 30 by screw with the first drive end support 60.
Fig. 6 and Fig. 7 is the structural representation of the damper 30 in an embodiment, and it is made up of outer ring (the first keeper 32), shock reducing structure 31, inner ring (the second keeper 33) three parts.It is an entirety that outer ring and inner ring are glued together by shock reducing structure 31, and wherein outer ring outwards turns down, and external part has some through holes, passes for screw, is connected with the second vibration end support 50 or the second drive end support 70; Inner ring fold inward, external part also has some through holes, passes for screw, is connected with the first vibration end support 40 or the first drive end support 60.
In the vibration end of Fig. 4 left end, because the endoporus of the outer ring of damper 30 and the second vibration end support 50 is matching relationships, the outer end flanging of outer ring plays axial location effect; In like manner, the inner ring of damper 30 and the cylindrical of the first vibration end support 40 are matching relationships, and the flanging of inner ring plays axial location effect, and therefore, damper 30 is mainly by radial load effect, but this radial load is extruding force to shock reducing structure 31 or tensile force.
In like manner, at the drive end of Fig. 4 right-hand member, because the endoporus of the outer ring of damper 30 and the second drive end support 70 is matching relationships, the outer end flanging of outer ring plays axial location effect; The inner ring of damper 30 and the cylindrical of the first drive end support 60 are matching relationships, and the flanging of inner ring plays axial location effect, and therefore, damper 30 is mainly by radial load effect, but this radial load is extruding force to shock reducing structure 31 or tensile force.
Therefore, no matter be at vibration end or drive end, damper 30 is all mainly by radial load effect, and this radial load is to shock reducing structure 31 extruding force in a circumferential direction or tensile force, and then avoids damper 30 because cross section bearing larger shearing force.
