Abstract
The utility model discloses an anti-falling and oil injectable roller which consists of a roller dustproof end cover, a roller, a roller shaft, a bearing, a skeleton-type sealing ring, an oil cup and a check ring. The bearing is mounted inside the roller; the check ring sleeves the bearing; the roller shaft is in clearance fit with the bearing; the oil cup is mounted on the roller shaft; the roller dustproof end cover is mounted at the end of the roller shaft; and the skeleton-type sealing ring is mounted outside the check ring. According to the utility model, on the basis of a roller assembly, an anti-falling device and a roller bearing oil injection facility are added; and the structure not only eliminates the potential safety hazard that the roller falls down, but also can ensure normal lubrication on the bearing inside the roller so as to prolong the service life of the roller.
Description
Technical field
The utility model relates to building hoist field of mechanical technique, is specially anticreep and can oil-filling type roller.
Background technology
Building hoist roll wheel assembly is to make construction elevator cage and driver plate along normal move a kind of auxiliary of guide rail bracket
Help guide piece.Novel roller anticreep is to increase anti-drop device on the basis of roll wheel assembly, the potential safety hazard that while having eliminated the bearing et out of order of roll wheel assembly inside, roller comes off.Building hoist be a kind of can the various building materialss of layering vertical transport and workmen's goods passwnger lift, be not only applicable to the high-story house construction of building industry, also be widely used in thermal power station, nuclear station, bridge engineering construction simultaneously, along with the domestic dwelling construction sustainable development that particularly economic guarantee room is built, building hoist is existing significantly to be increased, within 2012, home market injected volume is over 20,000, estimate that total domestic demand amount in 2013 will continue to keep prior year level, and export volume will be over last year.At present, roller anticreep used and can oiling form generally adopt and be provided with lubricating cup or increase anticreep board-like and be provided with lubricating cup on roller end cap on cover of dust on existing building hoist, these two kinds of version appearances are not attractive in appearance, complex structure, manufacture efficiency are lower.
Utility model content
The purpose of this utility model is for for the problems referred to above, and a kind of eccentric shaft that can eliminate roll wheel assembly is provided, and can guarantee again the normal lubricated of roller internal bearings, thus the disconnecting preventing that extends roller service life and can oil-filling type roller.
In order to achieve the above object, the technical scheme that the utility model is taked is:
Anticreep and can oil-filling type roller, is comprised of the dustproof end cap of roller, roller, roller shaft, bearing, matrix type seal ring, lubricating cup and back-up ring, and described bearing is arranged on roller inside, and shield ring sleeve is contained in bearing outside; Roller shaft and bearing interference fit, described lubricating cup is arranged on roller shaft, and the dustproof end cap of described roller is arranged on roller axle head, and matrix type seal ring is arranged on outside back-up ring.
As preferably, described roll wheel assembly is arranged in the counterbore plate on cage column beam.
As preferably, the dustproof end cap of described roller, roller, bearing, matrix type seal ring, back-up ring are arranged on roller shaft.
As preferably, described lubricating cup is through type forced filling oil cup.
The beneficial effects of the utility model are: the utility model has added anti-drop device and roller bearing oiling facility on the basis of roll wheel assembly, this structure had both been eliminated the potential safety hazard that roller comes off, can guarantee again the normal lubricated of roller internal bearings, thereby extend the service life of roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1-roller end cap that prevents dust; 2-roller; 3-roller shaft; 4-back-up ring I; 5-bearing; 6-back-up ring II; 7-back-up ring III; 8-matrix type seal ring; 9-lubricating cup.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated.
As shown in Figure 1, anticreep and can oil-filling type roller, is comprised of the dustproof end cap 1 of roller, roller 2, roller shaft 3, bearing 5, matrix type seal ring 8, lubricating cup 9 and back-up ring, and described bearing 5 is arranged on roller 2 inside, and shield ring sleeve is contained in bearing 5 outsides; Roller shaft 3 and bearing 5 interference fit, described lubricating cup 9 is arranged on roller shaft 3, and the dustproof end cap 1 of described roller is arranged on roller shaft 3 ends, and matrix type seal ring 8 is arranged on outside back-up ring.
Described roll wheel assembly is arranged in the counterbore plate on cage column beam; The dustproof end cap 1 of described roller, roller 2, bearing 5, matrix type seal ring 8, back-up ring are arranged on roller shaft 3; Described lubricating cup 9 is through type forced filling oil cup.
The utility model is when roller shaft et out of order, and back-up ring I 4, back-up ring II 6 and back-up ring III 7 can stop roller 2 to come off, and carries out oiling can to bearing 5 by lubricating cup 9, thereby extends the service life of roller 2.
Such scheme is preferred embodiment of the utility model, but is not changing under spiritual background of the present utility model, and any improvement of doing, within all dropping on protection domain of the present utility model.
