Abstract
The utility model relates to an impact idler of a conveying machine. A carrier roller pipe is arranged on a carrier roller shaft in a movable mode through bearings, a rubber ring is sleeved on the carrier roller pipe, the inner diameter of the rubber ring is smaller than the outer diameter of the carrier roller pipe, the rubber ring and the carrier roller pipe are in interference match, two ends of the carrier roller pipe are fixedly provided with check rings, and the rubber ring is located between the check rings at two ends of the carrier roller pipe. The impact idler of the conveying machine is convenient to manufacture and long in service life.
Description
Technical field
The utility model relates to a kind of conveyer that material is carried, the impact idler of the band conveyor of especially lump material being carried.
Background technology
The impact idler of existing band conveyor (as DTII type belt conveyer), the carrying roller pipe rotates by bearing and is arranged on roller carrier shaft, and rubber ring sleeve is contained on the carrying roller pipe.Rubber ring is to compress with circular nut, expends man-hour, and the tube material wall thickness is large, does not press tightly.Second, rubber ring is for ease of filling with the carrying roller pipe box, the large 0.5mm of its aperture ratio carrying roller pipe external diameter, like this, when material drops on belt conveyor, power passes after rubber ring, rubber ring can be constantly radially movable, movable gap is just in time the 0.5mm of cushion rubber endoporus, radial friction so ceaselessly, and rubber ring turns (and carrying roller Guan Buzhuan of the inside) with belt conveyor.Rubber ring is just not long service life.The 3rd, former rubber ring hardness generally is not less than Xiao A hardness HA80, hardens and can break to the winter rubber circle.
The utility model content
The purpose of this utility model is to provide a kind of impact idler of conveyer of easily manufactured, long service life.
The impact idler of conveyer described in the utility model, carrying roller pipe rotate by bearing and are arranged on roller carrier shaft, and rubber ring sleeve is contained on the carrying roller pipe; The diameter of bore of rubber ring is less than the external diameter of carrying roller pipe, and rubber ring and carrying roller pipe form interference fit; Two ends at the carrying roller pipe are fixed with back-up ring, and rubber ring is between the back-up ring at two ends.
The beneficial effects of the utility model: rubber ring and carrying roller pipe form interference fit, and the impulsive force that material is pricked after belt conveyor passes to the carrying roller pipe through rubber ring, and can not cause the wearing and tearing to the rubber ring endoporus, the rubber ring long service life.Through being 3m/s in the belt conveyor belt speed, bandwidth B=1400mm, material are block stone, and operational throughput is to test on the band conveyor of 2800t/h, and the service life of impact idler is at 50,000 hours, than having improved 30%-40% original service life.
The impact idler of above-mentioned conveyer, the diameter of bore of rubber ring is than the little 1mm of carrying roller pipe external diameter.Between rubber ring and carrying roller pipe, swelling 1mm close-fitting rotates, and the impulsive force that material is pricked after belt conveyor passes to the carrying roller pipe through rubber ring, and can not cause the wearing and tearing to the rubber ring endoporus, the rubber ring long service life.
The impact idler of above-mentioned conveyer, the Xiao A hardness HA=55-60 of rubber ring.Like this, to winter also hardened unlike originally, springiness, good buffer effect.
Description of drawings
Fig. 1 is the impact idler schematic diagram of conveyer.
The specific embodiment
Below in conjunction with embodiment and application examples, the utility model is elaborated.It is pointed out that illustrated embodiment is better embodiment of the present utility model, rather than to the restriction of the claimed scope of the utility model, application of the present utility model and using method also are not limited to the application examples of lifting.
The impact idler of conveyer shown in Figure 1, carrying roller pipe 1 rotate by bearing 2 and are arranged on roller carrier shaft 3, and rubber ring 4 is sleeved on the carrying roller pipe; The diameter of bore of rubber ring is than the little 1mm of carrying roller pipe external diameter, and rubber ring and carrying roller pipe form interference fit.The Xiao A hardness HA=55-60 of rubber ring.Be fixed with back-up ring 5 at the two ends of carrying roller pipe, rubber ring is between the packing ring at two ends.
Claims (3)
1. the impact idler of conveyer, the carrying roller pipe rotates by bearing and is arranged on roller carrier shaft, and rubber ring sleeve is contained on the carrying roller pipe; It is characterized in that: the diameter of bore of rubber ring is less than the external diameter of carrying roller pipe, and rubber ring and carrying roller pipe form interference fit; Two ends at the carrying roller pipe are fixed with back-up ring, and rubber ring is between the back-up ring at two ends.
