Abstract
The utility model discloses a carrier roller for a heading machine, and aims at providing the improved carrier roller for the heading machine. The carrier roller for the heading machine comprises a wheel body. The carrier roller is characterized in that a supporting axle is arranged at the center of the wheel body; two ends of the supporting axle are screwed with hexagon bolts; a rolling bearing, an elastic collar for a shaft and a skeleton-type rubber oil seal are also arranged at two ends of the supporting axle; the elastic collar for the shaft is arranged between the rolling bearing and the skeleton-type rubber oil seal. The carrier roller for the heading machine is mainly applied to a cantilever coal mine machine.
Description
Technical field
The utility model relates to a kind of holder sprocket wheel, relates in particular to a kind of development machine with holding in the palm sprocket wheel.
Background technology
Development machine holder sprocket wheel is that the upper that supports crawler belt does not make it sagging, and can reduce the crawler belt up-down vibration.Traditional holder sprocket wheel is made up of rotating wheel body, axle sleeve, potted component and bolster etc.When crawler belt in when walking, bolster is rotating by axle sleeve always, to refuel lubricated in the wheel body, if sealing effectiveness is bad, then be easy to produce the phenomenon of leakage of oil, and the friction between axle sleeve and the bolster belongs to sliding friction, bolster and axle sleeve are under unlubricated situation like this, be easy to wearing and tearing, may cause product to use at last.
Summary of the invention
The purpose of this utility model is to provide a kind of development machine with holding in the palm sprocket wheel, and this holder sprocket wheel changes traditional sliding bearing of being made up of axle sleeve into rolling bearing, changes sliding friction into rolling friction.Utilize rubber oil seal with reinforce to be installed in the two ends of bolster, play the grease proofing sealing function of good dust-proof, guarantee that rolling bearing is operated in lubricating status, hex bolts is the fulcrum that installs and fixes of holder sprocket wheel.
For achieving the above object, technical solution of the present utility model is: a kind of development machine is with holding in the palm sprocket wheel, comprise wheel body, it is characterized in that: the center of described wheel body 3, be provided with bolster 4, the two ends of this bolster and hex bolts 1 are spirally connected, and the two ends of bolster 4 also are provided with rolling bearing 5, circlip for shaft 2 and rubber oil seal with reinforce 6, and circlip for shaft 2 is between rolling bearing 5 and rubber oil seal with reinforce 6.
The beneficial effects of the utility model are:
1, adopts rolling bearing to replace sliding bearing, greatly reduce the abrasion of holder sprocket wheel, prolonged its application life.
2, the holder sprocket wheel turns round fulcrum with hex bolts as it, and installation and removal are convenient.
3, it is dustproof and grease proofing, simple and practical to adopt rubber oil seal with reinforce to be used for.
4, overall structure novelty, volume are less, are particularly suitable for medium and small development machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1----hex bolts, 2---circlip for shaft, 3---wheel body, 4---bolster, 5----rolling bearing, 6----rubber oil seal with reinforce.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to Fig. 1, the utility model comprises wheel body, it is characterized in that: the center of described wheel body 3, be provided with bolster 4, the two ends of this bolster and hex bolts 1 are spirally connected, the two ends of bolster 4 also are provided with rolling bearing 5, circlip for shaft 2 and rubber oil seal with reinforce 6, and circlip for shaft 2 is between rolling bearing 5 and rubber oil seal with reinforce 6.
