Abstract
Disclosed is a mid-set type vibration box of a vibratory road roller, which comprises a vibration box (2), a vibratory shaft (3), vibrating bearings (4), an eccentric block (5) and a vibration box flange (7), the vibratory shaft (3) threads through the center of the vibration box (2), and the upper part thereof is nested by the eccentric block (5), and the two ends of the eccentric block (5) are provided with the vibrating bearings (4). The utility model is characterized in that the vibration box flange (7) for connecting the vibrating spoke plate (1) and the vibration box (2) is designed to be positioned in the middle of the box body of the vibration box (2), and the vibrating bearings (4) for supporting the vibratory shaft (3) are symmetrically arranged at the two sides of the vibration box flange (7). Compared with the prior art, the utility model is characterized in that the distance between the center of gravity of the eccentric block and the central line of the vibrating spoke plate is small or basically superposed, the spoke plate of the vibrating wheel will not engender bending and elastic deformation due to the accessional bending moment, and the service life of the vibrating bearings can be extended under the condition of large excitation force without the need for enhancing the rigidity of the spoke plate of the vibrating wheel.
Description
Technical field:
The utility model relates to the vibratory roller in road building machinery field, is specifically related to the improvement of the structure of large-scale, ultra-large type vibratory roller vibrating bin.
Background technology:
The structure of existing vibratory roller vibrating bin is the end that the flange that is used for the vibrating wheels installing and locating is positioned at casing.After vibrating bin was installed on the vibrating wheels, vibrating bin is actual to be to be in an end cantilever position.Vibratory roller is when work, the huge exciting force that eccentric block produces passes to vibrating wheels by the mounting flange of vibrating bin, because the exciting force action plane departs from the vibrating wheels former, at this moment the former of vibrating wheels can be subjected to the additional bending moment effect and produce elasticity of flexure distortion, vibrating bin cantilever end circumference whipping, make vibrating shaft produce axial force, cause vibration bearing to heat up too high and damage.
The utility model content:
Technical problem to be solved in the utility model is the elasticity of flexure distortion that reduces the vibrating wheels former, the application life of improving vibration bearing.
Technical problem of the present utility model is to solve by following technical scheme.Its involving vibrations case, vibrating shaft, vibration bearing, eccentric block, vibrating bin flange, described vibrating shaft is arranged in vibrating bin central authorities, be with eccentric block on it, vibration bearing is established at the eccentric block two ends, and the utility model characteristics are that the vibrating bin flange that will connect vibrating wheels former and vibrating bin places in the middle of the vibration box body, the vibration bearing of supporting vibrating shaft is arranged symmetrically in vibrating bin flange both sides, so that the exciting force action plane does not depart from the vibrating wheels former.
The utility model and prior art are relatively, its distinguishing feature is that the eccentric block center of gravity is little with vibrating wheels former centreline spacing or overlap substantially, the former of vibrating wheels can not be subjected to the additional bending moment effect and produce elasticity of flexure distortion, and must not strengthen the rigidity of vibrating wheels former, just can be under big exciting force condition, the life-span of improving vibration bearing.
Description of drawings:
Fig. 1 is the utility model structure embodiment schematic diagram.
Among the figure:
1-vibrating wheels former; The 2-vibrating bin; The 3-vibrating shaft; The 4-vibration bearing;
The 5-eccentric block; The 6-shaft coupling; 7-vibrating bin flange; The 8-vibrating wheels.
The specific embodiment:
As shown in Figure 1, the utility model involving vibrations case 2, vibrating shaft 3, vibration bearing 4, eccentric block 5, vibrating bin flange 7, present embodiment vibrating bin 2 sets up two separately, be fixed on the vibrating wheels former 1 set on the vibrating wheels 8 by vibrating bin flange 7 respectively, described vibrating shaft 3 is arranged in vibrating bin 2 central authorities, and two vibrating shafts 3 are coupled to each other by shaft coupling 6.On vibrating shaft 3, be with eccentric block 5 respectively, vibration bearing 4 is established at eccentric block 5 two ends, place on vibrating bin 2 casings, with supporting vibrating shaft 3, the utility model characteristics are to connect the centre of vibrating bin flange 7 designs of vibrating wheels former 1 and vibrating bin 2 at vibrating bin 2 casings, the vibration bearing 4 of supporting vibrating shaft 3 is arranged symmetrically in the both sides of vibrating bin flange 7, like this, be installed on the vibrating shaft 3 and to be positioned at eccentric block 5 centers of gravity of vibrating bin 2 centers very little with vibrating wheels former 1 centreline spacing or overlap substantially, therefore, the exciting force action plane can not depart from the former 1 of vibrating wheels, just can not be subjected to the additional bending moment effect yet and produce elasticity of flexure distortion, also not have axial force and produce, thus the life-span of having improved vibration bearing 4.
The utility model installation process: earlier vibrating shaft 3, vibration bearing 4, eccentric block 5 are installed in the vibrating bin 2, form the vibrating bin assembly, again this assembly is installed on the vibrating wheels former 1.Be contained in during work motor on the frame by transmission with power inputted vibration axle 3, it is rotated at a high speed, the eccentric block 5 that is installed on the vibrating shaft 3 produces exciting forces, drives vibrating wheels 8 work.
Claims (1)
1, a kind of vibratory roller middle-set-type vibrating bin, its involving vibrations case (2), vibrating shaft (3), vibration bearing (4), eccentric block (5), vibrating bin flange (7), described vibrating shaft (3) is arranged in vibrating bin (2) central authorities, be with eccentric block (5) on it, vibration bearing (4) is established at eccentric block (5) two ends, the utility model is characterised in that the vibrating bin flange (7) with connection vibrating wheels former (1) and vibrating bin (2) designs in the middle of vibrating bin (2) casing, and the vibration bearing (4) of supporting vibrating shaft (3) is arranged symmetrically in vibrating bin flange (7) both sides.
