A kind of belt roller can avoiding scuffing belt
Technical field
The present invention relates to the belt roller that a kind of belt-conveying uses, belong to belt transporting facility technical field.
Background technology
Belt Conveying is the important way of modern factories transport raw material or product, and big-and-middle-sized belt transporter comprises left side carrying roller, right side carrying roller and flat idler component movement framework.The weight of the material that belt bears is born by left side carrying roller, flat idler and right side carrying roller, and three carrying rollers respectively rotate around the antifriction-bearing box of self.In course of conveying, the belt between two carrying rollers causes distortion due to the gravity extruding of material, is out of shape sagging belt under the effect of carrying roller end corner angle and friction force, will soon be scratched, to such an extent as to generation breach, have to scrap.The belt more renewed not only adds productive costs, and adds maintenance time, have impact on carrying out smoothly of production.Therefore, transform carrying roller, it is very necessary for preventing preventing belt from scratches and scrapping.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind ofly to go slick, friction drag is little, can the belt roller can avoiding scratching belt of available protecting belt.
The technical scheme solved the problems of the technologies described above is:
A kind of belt roller can avoiding scuffing belt, it comprises roller carrier shaft, end cap, roller carrier shaft bearing, steel cylinder, end cap is arranged on the two ends of roller carrier shaft, roller carrier shaft bearing is arranged between roller carrier shaft and end cap, between the end cap top at two ends, steel cylinder is installed, its improvements are, the periphery of steel cylinder is set with anti-wear sleeve, between anti-wear sleeve and end cap, antifriction-bearing box is installed, the excircle of antifriction-bearing box is higher than the excircle of two ends end cap, and the outer surface of anti-wear sleeve and the outer surface of antifriction-bearing box flush.
The above-mentioned belt roller can avoiding scuffing belt, is separately installed with antifriction-bearing box between described anti-wear sleeve and two ends end cap.
The above-mentioned belt roller can avoiding scuffing belt, is provided with antifriction-bearing box between described anti-wear sleeve and one end end cap.
The invention has the beneficial effects as follows:
The present invention has installed anti-wear sleeve and antifriction-bearing box outward at the steel cylinder of carrying roller; the antifriction-bearing box of contact belt revolves round the sun around roller carrier shaft again while steel cylinder rotation; both the friction to belt had been alleviated; effectively protect again belt not by the injury of original carrying roller corner angle, more avoid directly scratching belt because of roller carrier shaft bearing damage.Structure of the present invention is simple, go slick, friction drag is little, can available protecting belt, can transform with existing rubber idler, not only reduce cost, and more than running life is ten times of former carrying roller, economic benefit is obvious, has promotional value.

In figure, mark is as follows: roller carrier shaft 1, end cap 2, roller carrier shaft bearing 6, anti-wear sleeve 4, steel cylinder 5, antifriction-bearing box 3, left side carrying roller 7, flat idler 8, right side carrying roller 9, belt 10, raw material 11, belt and flat idler contact point 12, belt and left side carrying roller contact point 13.
Detailed description of the invention
The present invention is made up of roller carrier shaft 1, end cap 2, roller carrier shaft bearing 6, anti-wear sleeve 4, steel cylinder 5, antifriction-bearing box 3.
Show in figure, end cap 2 is arranged on the two ends of roller carrier shaft 1, and roller carrier shaft bearing 6 is arranged between roller carrier shaft 1 and end cap 2, between end cap 2 top at two ends, be provided with steel cylinder 5.The structure of this part is identical with existing rubber idler, can adopt existing rubber idler, or utilizes waste and old or discarded rubber idler, removes rubber bodies.
Show in figure, anti-wear sleeve 4 is set with in the periphery of steel cylinder 5, be provided with antifriction-bearing box 3 between anti-wear sleeve 4 and end cap 2, the excircle of antifriction-bearing box 3 is higher than the excircle of two ends end cap 2, and the outer surface of anti-wear sleeve 4 and the outer surface of antifriction-bearing box 3 flush.
In practical set, first steel cylinder 5 is polished, measure steel cylinder 5 external diameter with this steel cylinder 5 for the diameter of axle, choose corresponding antifriction-bearing box 3, be directly installed on by antifriction-bearing box 3 on steel cylinder 5, middle installation anti-wear sleeve 4, the external diameter of anti-wear sleeve 4 is consistent with the external diameter of antifriction-bearing box 3.
Show in figure, adopt the belt roller of this structure, during installation, the two ends of flat idler 8 all must install antifriction-bearing box 3 additional, and left side carrying roller 7, right side carrying roller 9 only need one end to install antifriction-bearing box 3 additional.
The present invention can be used in after belt 10 is climbed and become level attitude junction.
