Abstract

The utility model relates to a vibrating output bearing structure for a vibration exciter of a directional vibrating road roller, which is mainly composed of a casing body of the vibration exciter, eccentric shafts, a coupler, a synchronous gear, a driving gear, a vibrating bearing, a vibrating output bearing, a vibrating output bearing seat, etc. The exciting force generated by a plurality of eccentric shafts is transferred to the casing body of the vibration exciter, and then, the exciting force is transferred to the vibrating output bearing from the casing body of the vibration exciter. In the end, the exciting force is transferred to a vibrating wheel body by the vibrating output bearing seat. The vibrating output bearing is a radial joint bearing. The utility model has the advantages of simple structure, low vibration noise and favorable sealing performance.

Description

The vibration output shaft bearing structure of directional vibration road roller vibration exciter

The utility model relates to a kind of vibration output shaft bearing structure of directional vibration road roller vibration exciter, belongs to the road building machine field.

The vibratory roller of extensive use now almost all is non-directional vibration road roller, the vibration exciter of this vibratory roller is that the centrifugal force that single eccentric shaft produces when high speed rotating is directly passed to the vibration wheel body by vibration bearing, force the vibration of the circumferencial direction of vibration wheel body work and eccentric shaft same frequency, simultaneously, vibration exciter itself can roll with the vibration wheel body, and the directional vibration road roller that occurs in recent years, its vibration exciter is that multiple-eccentric shaft is installed in parallel in vibration exciter housing (or claiming the vibration exciter scaffold), the centrifugal force that every eccentric shaft produces passes to the vibration exciter housing by vibration bearing separately, pass to the vibration wheel body by the vibration exciter housing through vibration output bearing again, force the vibration of vibration wheel body, simultaneously, the vibration exciter housing links to each other with the road roller frame, vibration exciter itself does not move with the rolling of vibration wheel body, owing to be difficult to guarantee in the coaxality processing of two vibration output shaft bearing mounting holes on the vibration wheel body, so, the vibration output bearing of existing directional vibration road roller vibration exciter all adopts the selfaligning roller bearing structure, the oscillating load that vibration output bearing need transmit is very big and rotating speed is low, makes that the specification of vibration output bearing of existing directional vibration road roller vibration exciter is very big; The noise of bearing is very big; Simultaneously, the mounting structure complexity of existing this vibration output bearing and sealing configuration are also complicated.

The purpose of this utility model is to provide a kind of new plain radial bearing structure, as the vibration output shaft bearing structure of directional vibration road roller vibration exciter, make the vibration output shaft bearing structure size of directional vibration road roller vibration exciter little, mounting structure is simple, good seal and vibrating noise are minimum.

The purpose of this utility model is achieved in that selects plain radial bearing (optimal selection is single seam outer ring plain radial bearing of two sides band seal ring), selected plain radial bearing is snugly fitted on the vibration output shaft bearing in pairs, vibration output shaft bearing is fixed in the mounting hole of vibration wheel body two ends again, selected plain radial bearing inner ring is fixed on the shaft part at vibration exciter housing two ends, be equipped with in the vibration exciter housing and be connected in parallel and symmetrical multiple-eccentric shaft and the multiple-eccentric shaft synchronous backward driving device of installing on the selection plane, because the excitation force of multiple-eccentric shaft is cancelled out each other on the selection plane, superposeing on the plane perpendicular to selecting, excitation force after the stack passes to vibration output shaft bearing by the vibration exciter housing through vibration output bearing and passes to the vibration wheel body again, the vibration wheel body is produced perpendicular to the once per revolution vibration of selecting on the plane, the vibration exciter housing connects through vibration damper and frame, and the vibration exciter housing does not move with the rolling of vibration wheel body.

Description of drawings of the present utility model is as follows:

Fig. 1 explanation:

1-running motor driving mechanism, 2-vibration damper 3-vibration wheel body 4-vibration exciter housing

5-eccentric shaft, 6-coupling, 7-synchromesh gear, 8-driving gear 9-input gear

10-vibrating motor input coupling, 11-vibrating motor

12-vibration output bearing 13-vibration output shaft bearing 14-vibration bearing

15-gear-box, 16-frame

Fig. 1 is the vibration output shaft bearing structure embodiment's of the directional vibration road roller vibration exciter that provides of the utility model a typical structure schematic diagram, running motor driving mechanism 1 is installed on the frame 16, running motor driving mechanism 1 drives vibration wheel body 3 by vibration damper 2 and rolls, vibration exciter housing 4 (or claiming the vibration exciter scaffold) is by vibration output bearing 12, vibration output shaft bearing 13 is installed in the vibration wheel body 3, vibration output bearing 12 is a two sides band seal ring list seam outer ring plain radial bearing, the vibration exciter housing also claims to connect symmetry installation two eccentric shafts 5 on the 4 inherent selection planes, vibration bearing 14 is assemblied on the eccentric shaft 5, gear-box 15 is arranged in the input end of two eccentric shafts 5 and is installed in the vibration exciter housing 4, be equipped with driving gear 8 in the gear-box 15, synchromesh gear 7 and input gear 9, connect by coupling 6 between synchromesh gear 7 and driving gear 8 and the eccentric shaft 5, connect by vibrating motor input coupling 10 between input gear 9 and the vibrating motor 11, vibrating motor 11 is installed in the end of vibration exciter housing 4, and vibration exciter housing 4 links to each other with frame 16 by vibration damper 2.

The embodiment's that the utility model provides working procedure is: vibrating motor 11 drives input gear 9 by vibrating motor input coupling 10, input gear 9 drives driving gear 8, driving gear 8 and synchromesh gear 7 are meshed, driving gear 8 and synchromesh gear 7 drive two eccentric shafts 5 by coupling 6 synchronous backwards, because two eccentric shafts 5 symmetric arrangement on the plane of selecting is installed, so, cancel out each other on the in-plane that the centrifugal force that produces during 5 rotations of two eccentric shafts is selected when mounted, superpose on the in-plane of perpendicular to installation the time, selecting, excitation force after the stack passes to vibration output bearing 12 by vibration exciter housing 4, vibration output bearing 12 passes to vibration wheel body 3 through vibration output shaft bearing 13, it is consistent with the excitation force direction to force vibration wheel body 3 to be done, the vibration that frequency is identical, when running motor driving mechanism 1 drives 3 rollings of vibration wheel body by vibration damper 2, vibration exciter housing 4 does not roll with vibration wheel body 3, and the in-plane of selecting when promptly two eccentric shafts 5 keep initial the installation is constant.

The embodiment's who provides by the utility model structural principle, Machine Design routinely and manufacture method can realize the application of the vibration output shaft bearing structure of the directional vibration road roller vibration exciter that the utility model provides.

With the outer figure plain radial bearing structure of single seam of two sides band sealing vibration output shaft bearing structure, the vibration output shaft bearing structure of directional vibration road roller vibration exciter is become simply, move that noise is low, needn't arrange sealing configuration again in the long service life, bearing mounting structure as the directional vibration road roller vibration exciter.
