Abstract
The utility model discloses a carrying roller for belt conveyor, comprising two bearing (1), two labyrinth sealing (2), two positioning clamp spring (3), a roller carrier shaft (4) and a metal sleeve (5). The bearing (1) is inlaid on the shaft shoulders of the two ends of the roller carrier shaft (4), the two labyrinth sealing (2) are respectively arranged the outer sides of the two bearings (1) and axially positioned by the positioning clamp spring (3), and the two bearings (1) and the two labyrinth sealing (2) are respectively arranged in the inner bore of the two ends of the metal sleeve (5). The carrying roller for belt conveyor also comprises a rubber coating layer (6), and the rubber coating layer (6) is coated on the surface of the outer circle of the metal sleeve (5) and the outer end faces of the two labyrinth sealing (2). An oil feeding hole (7) is arranged between the surface of the outer circle of the rubber coating layer (6) and the surface of the inner bore of the metal sleeve (5). The interstice between the surface of the outer circle of the roller carrier shaft (4) and the rubber coating layer (6) is small, and then the bearing (1) not only has the sealing of the labyrinth sealing (2) and also has the sealing of rubber seal. Therefore, the sealing effect is better than the sealing effect of the existing roller. The utility model has the advantages of professional design and reliable operation.
Description
Technical field:
The utility model relates to a kind of carrying roller of belt transporter.
Background technology:
Belt transporter often will be used in working space such as mine, factory.The carrying roller of belt transporter belongs to vulnerable part, and be of great importance to reducing production costs the service life that therefore prolongs it.Find that in use existing carrying roller is poorly sealed at shaft end, the foreign matter that causes the carrying roller neck bearing to be entered easily covers stuck, has reduced the service life of carrying roller.
The utility model content:
In order to overcome the poorly sealed defective of existing carrying roller axle head, provide the carrying roller of the tight-closed belt transporter of a kind of axle head.The technical solution of the utility model is as follows: a kind of carrying roller of belt transporter, it comprises two bearings 1, two labyrinth seals 2, two location jump rings 3, roller carrier shaft 4, metallic sheath 5, bearing 1 is set in the shaft shoulder place, two ends of roller carrier shaft 4, two labyrinth seals 2 are separately positioned on the outside of two bearings 1 and are positioned jump ring 3 axial location, two bearings 1 and two labyrinth seals 2 are arranged at respectively in the endoporus at metallic sheath 5 two ends, it also comprises rubber adhesive 6, rubber adhesive 6 is coated on the outer face of the outer round surface of metallic sheath 5 and two labyrinth seals 2, has oil hole 7 between the bore area of the outer round surface of rubber adhesive 6 and metallic sheath 5.Because rubber adhesive 6 had not only wrapped up the outer round surface of metallic sheath 5 but also the outer face integral body of location jump ring 3, the gap is minimum between the outer round surface of roller carrier shaft 4 and the rubber adhesive 6, make bearing 1 except labyrinth seal 2 these road sealings, added rubber seal again one, therefore sealing effectiveness is better than existing carrying roller, and oil hole 7 is used for annotating butter in carrying roller, strengthens lubricating bearing 1, after having annotated butter, oil hole 7 is blocked.The advantage that the utlity model has reasonable in design, reliable operation and be suitable for promoting.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The specific embodiment one: specify present embodiment below in conjunction with Fig. 1.Present embodiment is by two bearings 1, two labyrinth seals 2, two location jump rings 3, roller carrier shaft 4, metallic sheath 5 and rubber adhesive 6 are formed, bearing 1 is set in the shaft shoulder place, two ends of roller carrier shaft 4, two labyrinth seals 2 are separately positioned on the outside of two bearings 1 and are positioned jump ring 3 axial location, two bearings 1 and two labyrinth seals 2 are arranged at respectively in the endoporus at metallic sheath 5 two ends, rubber adhesive 6 is coated on the outer face of the outer round surface of metallic sheath 5 and two labyrinth seals 2, has oil hole 7 between the bore area of the outer round surface of rubber adhesive 6 and metallic sheath 5.Rubber adhesive 6 is selected the material of flame retardant rubber.Present embodiment is applicable to the working space under the coal mine, because the down-hole often has gas to exist, so anti-gas explosion, anti-burning very important for safety in production, rubber adhesive 6 itself just has the advantage of avoiding metal bump to produce spark, add and used flame retardant rubber, make production safer.
The specific embodiment two: specify present embodiment below in conjunction with Fig. 1.The difference of present embodiment and embodiment one is that the outer round surface of metallic sheath 5 is provided with some road ring-type rib band 5-1.So be provided with, vulcanize higher with the intensity that metallic sheath 5 combines at metallic sheath 5 lip-deep rubber adhesives 6.Other composition is identical with embodiment one with annexation.
The specific embodiment three: specify present embodiment below in conjunction with Fig. 1.The difference of present embodiment and embodiment one is to have oil groove 4-1 and the oil groove 4-2 of helix around roller carrier shaft 4 outer round surface on the roller carrier shaft 4 between two bearings 1.So be provided with, the butter in the injection carrying roller is driven when roller carrier shaft rotates to bearing 1 direction to move.Other composition is identical with embodiment one with annexation.
The specific embodiment four: specify present embodiment below in conjunction with Fig. 1.The difference of present embodiment and embodiment one is, the place, end of rubber adhesive 6 is set to the round platform 6-1 that increased gradually by interior lateral outer end portion external diameter.So be provided with, when carrying roller is worked, the effect of location arranged bearing belt on it.
