The specific embodiment
As shown in Figure 1, 2, a kind of supporting structure for vibrator of vibrating roller, the outer side surface of described vibrator housing 10 is connected with the supporting seat 31 that is arranged on road roller wheel body 30 inside by spring bearing 20.
As preferred version of the present invention, described spring bearing 20 reaches at the both ends of vibrator and is symmetrical arranged therebetween.This set-up mode can make the stressed comparatively balanced of spring bearing, thereby has prolonged its working life.
As another kind of preferred version of the present invention, as shown in Figure 2, described vibrator housing 10 is set to the left vibrator housing 13 and the right vibrator housing 14 of split, and the junction of left vibrator housing 13 and right vibrator housing 14 is provided with spring bearing 20.The eccentric block by the vibrating motor driven rotary is all contained in aforesaid left and right vibrator housing 11,12 inside, it comes down to carry and the modular unit of design for ease of installing and being beneficial to, and is referred to as left vibrator housing 13 and right vibrator housing 14 herein for the purpose of distinguishing.The present invention is provided with spring bearing 20 between left and right vibrator housing 13,14, can guarantee the even running of vibrator, and then has ensured the operate as normal of road roller.
As shown in Figure 1, 2, the two ends of described vibrator housing 10 are provided with collar 70, collar 70 is through the bearing support 81 at walking bearing 80 and backplate 32 inner ring places support fixation mutually, and the vibrator housing 10 upper edge axial length directions between two collars 70 are provided with 2～4 spring bearings 20.
Above-mentioned set-up mode has increased the contact area between vibrator housing 10 and the road roller wheel body 30, thereby has reduced the suffered pressure of spring bearing 20 of carrying vibrator, has reduced the possibility that spring bearing 20 breaks down.
As shown in Figure 1, 2, be provided with the grease-box 40 of tubular between the backplate 32 of described vibrator housing 10, road roller wheel body 30 and vibrator both sides, lubrication oil gathers in the bottom of grease-box 40 and is oil sump, below the mouth of pipe oil-drowned liquid level of fuel sucking pipe 60, lubrication oil forms a complete circulating lubricating path along oil leab, oil sump and the fuel sucking pipe 60 of fuel sucking pipe 60, lubricated cooling body, fuel feed pump 50, spring bearing 20 successively.
Above-mentioned set-up mode can make spring bearing 20 obtain effective lubricating, to guarantee that spring bearing 20 has good working order.
As preferred version of the present invention, as shown in Figure 1, the external diameter of described grease-box 40 is slightly larger than the diameter of spring bearing 20 outside anchor rings, the outside anchor ring of spring bearing 20 and the plate body of the supporting seat 31 between the grease-box 40 are provided with perforate 311, and the lubrication oil in the oil sump is communicated with as a whole by perforate 311.
As a whole by the lubrication oil in the oil sump is communicated with, thus be convenient to the use that circulates of lubrication oil.
As another kind of preferred version of the present invention, as shown in Figure 1, the lowermost end of described vibrator housing 10 is provided with oilhole 11, fuel feed pump 50 is connected to the oil distributing pipe 50A of vibrator inside top, the perforate of lubrication oil on oil distributing pipe 50A is divided into two-way, one the tunnel confluxes to vibrator housing 10 bottoms behind each bearing of lubricated eccentric block assembly, converges to oil sump through oilhole 11 again, confluxes to oil sump enter the oil leab of spring bearing 20 through the oilhole 12 at vibrator housing 10 tops after in another road.
The above-mentioned lubricating system of lubricating system has guaranteed the operate as normal of spring bearing 20 on the one hand, has also guaranteed the operate as normal of inner each bearing of vibrator on the other hand, thereby has effectively ensured the stable operation of vibratory roller.
Described supporting seat 31 is circular, supporting seat 31 radially be provided with equably along annulus reinforcing rib or supporting seat 31 bilateral symmetry be provided with stiffener 33.Owing to adopted reinforcing rib or stiffener 33 structures, the present invention has improved the rigidity and the intensity of supporting seat 31, has improved the force-bearing situation of supporting seat 31, thereby has prolonged the application life of spring bearing 20 and supporting seat 31.
Spring bearing 20 has multiple frame mode, such as being the double-row roller bearing among Fig. 2, as preferred version of the present invention, described spring bearing 20 is a sliding bearing, sliding bearing is set to nestablely be the interior cover 21 of sliding fit and overcoat 22 for one and mutually, interior cover 21 fixed covers of sliding bearing are located on the outer side surface of vibrator housing 10, and overcoat 22 is fixed on the bearing support on the supporting seat 31, shown in Fig. 3,4.
Aforesaid walking bearing 80 can be rolling bearing, also can be above-mentioned sliding bearing.
Because therefore cover 21 and overcoat 22 in being provided with make the ability of sliding bearing and supporting seat 31 carrying road roller deadweights and huge impulsive load improve greatly, have further ensured the stable operation of road roller.
As shown in Figure 4, it radially is provided with the counterbore that runs through its body equably the ring wall upper edge of described interior cover 21, bolt passes counterbore interior cover 21 and vibrator housing 10 is connected as one, it axially is provided with internal thread equably the ring wall upper edge of overcoat 22, is connected for screw between supporting seat 31 and the overcoat 22.
The said fixing connected mode is simple installation not only, also is convenient to simultaneously to realize the fine finishining between the face of cooperatively interacting of internally cover 21 and overcoat 22.
The lubricating system of interior cover 21 and overcoat 22 can adopt prior art, such as radially offering oilhole at interior cover 21, axially offer oil duct, lubrication oil enters oil duct by the perforate on the vibrator housing 10 along interior cover 21 oilholes, thereby lubricating bearings, as preferred version of the present invention, interior cover 21 middle parts of described sliding bearing along the circumferential direction are provided with oil-way 211, be evenly equipped with through hole 212 on the oil-way 211, through hole 212 is communicated with between oil-way 211 and interior cover 21 and the overcoat 22, as shown in Figure 4.
Among the present invention because the setting of circumferential oil-way 211, thereby the force feed oil that feasible oilhole 12 from vibrator housing 10 tops enters comes along oil-way 211 diffusions soon, and under the effect of oil pressure in through hole 212 enters the cover 21 and overcoat 22 between, thereby can realize sufficient lubrication, guarantee that sliding bearing is in good working order constantly sliding bearing.
