Embodiment
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
Fig. 1 shows the structure of prior art blending reclaimer bucket wheel body travelling wheel, its wheel shaft 4 is step solid shaft, not easily changes, and logical lid 3 is single sealing oil groove, sealing is poor, bearing 5 is tapered roller bearing, is applicable to bear heavy load and impact load, but generally should not bears axial load separately, fragile in running, inconvenience maintenance, often makes the manufacture cycle extend, and adds workman and overhaul labor intensity.
As shown in Fig. 2 ~ 6, the utility model comprises traveling wheel body 1, wheel carrier 2, logical lid 3, wheel shaft 4, bearing 5 and hollow shaft 6, described traveling wheel body 1 is fixedly arranged on wheel carrier 2 by wheel shaft 4, bearing 5, described traveling wheel body 1 both sides arrange logical lid 3, described wheel shaft 4 is optical axis integrative-structure, outside sheathed hollow shaft 6, described logical lid 3 is provided with double-sealing oil groove.
Internal diameter and bearing 5 size of described traveling wheel body 1 are suitable.
The internal diameter of described traveling wheel body 1 is Φ 200 ~ Φ 225.
Described traveling wheel body 1 is alloyed steel structure.
The outer ring raceway of described bearing 5 is spheric.
Described bearing 5 is selfaligning roller bearing.
Be provided with roller fatten passage in described wheel shaft 4, this passage extends in bearing inner sleeve.
It is great circle cambered surface that described traveling wheel body 1 takes turns roll surface.
Working principle of the present utility model and working procedure as follows:
The utility model adopts the wheel axle structure of optical axis overcoat hollow shaft, and the logical lid of double-sealing oil groove is set, adopt selfaligning roller bearing, and the travelling wheel of alloyed steel structure, improve the working life of blending reclaimer bucket wheel body traveling wheels, and facilitate daily repair and maintenance.
During work, change the internal diameter of traveling wheel body, to realize the remodeling of bearing, wheel shaft step solid shaft be designed to optical axis design, add hollow shaft, reduce the direct wearing and tearing to wheel shaft, and shortening the repair time, former wheels damage to be changed, and needs the time of 5 hours to complete, after improving, wheels are when changing, and the time can control to complete within 3 hours.Because field working conditions condition is poor, the feature that dust is larger, change the logical lid structure of single sealing oil groove into double-sealing oil groove, improve sealing effect, reduce because entering the bearing damage that ash causes insufficient lubrication to cause, life cycle is held short for primitive axis, change frequent, change former tapered roller bearing into selfaligning roller bearing, such bearing outer ring ball track is spheric, there is aligning performance at former residence, when axle is stressed bend or tilt and make inner ring center line and outer ring center line relative tilt be no more than 0.5 ° ~ 2 ° time, bearing still can normally work.Its structural principle is identical with selfaligning ball bearing with characteristic, and unique difference is that rolling element is spherical roller, and due to the difference of rolling element, thus its bearing capacity is comparatively large, this class bearing can the axial displacement of restrictive axes or shell within the scope of the axial internal clearance of bearing.By contrast, on blending reclaimer bucket wheel body traveling wheels, use selfaligning roller bearing to be better than tapered roller bearing, reach the object extending bearing life cycle.
