Abstract
The utility model relates to an improvement on a carrier roller of a band conveyor. A steel carrier roller of the band conveyor is changed into a plastic steel carrier roller; a rotary easy worn part is arranged in the internal part of a plastic steel bearing cup. The easy worn part and the plastic steel bearing cup are replaced together. The utility model solves the difficult problem that a metal carrier roller is easy to cut a strap and recover unnecessary economic losses for manufacture.
Description
Technical field
The utility model relates to a kind of improvement of belt conveyer carrying roller, particularly a kind of belt conveyer Plastics and steel support roller.
Background technology
At present, known belt conveyer carrying roller is to make with metallic materials such as steel pipes, and this carrying roller is in the environment that humidity and harmful liquid, gas exist, thus very easily corrosion, burn into accelerated wear test, reduction of service life.Especially after the steel pipe mill of this metal dragging roller leaked, damaged metal relic prolongs belt direction of travel severed belt, and a large amount of belts are scrapped, and causes cataphoretic failure to production.Simultaneously, the rotation consumable accessory of this carrying roller is non-exchange, gives to produce to keep in repair to make troubles.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the steel formula carrying roller of belt conveyer is made into Plastics and steel support roller, is placed on plastic-steel bearing cup inside rotating vulnerable part, when changing vulnerable part and plastic-steel bearing cup integral replacing.Plastic-steel bearing cup and Plastics and steel support roller body adopt the taper location, and installing/dismounting is very convenient, thereby a kind of belt conveyer Plastics and steel support roller is provided.
The technical solution of the utility model is: be pressed into the plastic-steel bearing cup respectively in Plastics and steel support roller body two stomidiums, be pressed into antifriction-bearing box in plastic-steel bearing cup inside, the antifriction-bearing box endoporus steel axle of packing into; Antifriction-bearing box external diameter and plastic-steel bearing cup internal diameter interference fit, antifriction-bearing box internal diameter and steel axle external diameter interference fit are also located with shaft block ring; In order to seal, the mystery palace seal ring of outside antifriction-bearing box and shaft block ring, packing into; In order to strengthen the Joint strenght of Plastics and steel support roller body and plastic-steel bearing cup, the Baltimore groove of the convex reinforced rib of Plastics and steel support roller body inwall and plastic-steel bearing cup external diameter forms spline and closely cooperates, and clenches solid with the self tapping gong in plastic-steel bearing cup side and Plastics and steel support roller body end face simultaneously.Plastic conveyer roller body inwall convex reinforced rib and back plate external diameter Baltimore groove form spline and closely cooperate back plate internal diameter and steel axle running-fit.
Because the utility model has adopted such scheme, makes to the utlity model has resistant to rust, erosion resisting performance, has solved the difficult problem that steel formula carrying roller cuts belt easily, also has easy installation and removal simultaneously, the advantage of being convenient to keep in repair.
Description of drawings
For the ease of understanding structure of the present utility model and implementing best mode of the present utility model, the utility model is further specified below in conjunction with accompanying drawing.
Fig. 1 is the utility model general assembly constructional drawing.
Fig. 2 is the assembly structure figure of the utility model plastic-steel bearing cup, antifriction-bearing box and Plastics and steel support roller body.
Fig. 3 is the assembly structure figure of the utility model back plate, steel axle and Plastics and steel support roller body.
In Fig. 1: at the two ends of Plastics and steel support roller body (1) plastic-steel bearing cup (5) is housed, at plastic steel shaft The endoporus that holds cup (5) is equipped with rolling bearing (7), in rolling bearing (7) outside shaft block ring (6) is housed, In shaft block ring (6) outside mystery palace sealing ring (3) is housed, by above-mentioned plastic-steel bearing cup (5), roll Dynamic bearing (7), shaft block ring (6) and mystery palace sealing ring (3) have formed the rotational support assembly, this Support component and Plastics and steel support roller body (1) are assembled on the steel axle (4); Interposition in Plastics and steel support roller body (1) Put one or more support plates (8) are housed, the outer warp of support plate (8) and Plastics and steel support roller body (1) internal diameter Closely cooperate, the interior warp of support plate (8) and steel axle (4) movingly, the outside of plastic-steel bearing cup (5) Face is fixed with tapping screw (2) and Plastics and steel support roller body (1) end.
In Fig. 2: outside the inwall convex reinforcement of Plastics and steel support roller body (1) and the plastic-steel bearing cup (5) The footpath Baltimore groove forms spline and closely cooperates, the internal diameter of the rolling bearing (7) that plastic-steel bearing cup (5) is inner With steel axle (4) interference fit.
In Fig. 3: the inwall convex reinforcement of Plastics and steel support roller body (1) and one or more support plates (8) The external diameter Baltimore groove form spline and closely cooperate, the internal diameter of support plate (8) and steel axle (4) are movingly.
The specific embodiment
The utility model implementation process is as follows: by shown in Figure 1, labyrinth seal (3), the shaft block ring (6) that will fill with oil earlier are respectively charged in the plastic-steel bearing cup (5) by Fig. 1 order; Back plate (8) is inserted in steel axle (4), again two antifriction-bearing boxs (7) are respectively charged into steel axle (4) two ends, the steel axle (4) that back plate (8) and antifriction-bearing box (7) will be housed the then inside of Plastics and steel support roller body (1) of packing into, the plastic-steel bearing cup (5) that labyrinth seal (3), shaft block ring (6) will be housed again is respectively installed to the two ends of Plastics and steel support roller body (1), antifriction-bearing box (7) also is loaded into plastic-steel bearing cup (5) inside simultaneously, uses thread-forming screw (2) that plastic-steel bearing cup (5) and Plastics and steel support roller body (1) is fixing at last.
