Abstract
The utility model relates to a multi-seal carrier roller which comprises a roller body, a rotating shaft, bearings, bearing bases, sealing rings, internal labyrinth seals, external labyrinth seals, an internal check ring, an outer check ring, sealing plates and end covers. The bearing bases are respectively arranged at two ends of the roller body. The bearings are contained in the bearing bases. The rotating shaft is supported on the bearings. The sealing rings are arranged on the inner sides of the bearings, and the internal labyrinth seals, the external labyrinth seals, the sealing plates and the end covers are sequentially arranged on the outer sides of the bearings. The internal check ring and the external outer ring are connected in a clamping mode and connected between the end covers and the sealing plates in an abutting mode. As sealing structures such as the sealing rings, the internal labyrinth seals, the external labyrinth seals and the sealing plates are arranged, the carrier roller is good in sealing property, sediment and dust do not enter the bearings easily, and service life of the carrier roller is long.
Description
Technical field
The utility model relates to a kind of constituent elements of belt conveyer for coal mine, is specifically related to a kind of many sealing idler rollers, belongs to the coal transport equipment technical field.
Background technology
Carrying roller is the important composition parts of belt conveyer for coal mine, and its inside is typically provided with a bearing.For the rotation of assurance bearing is flexible, often need the end of bearing is sealed.
The hermetically-sealed construction of the carrying roller of prior art is generally single layer structure, and its sealing effectiveness is relatively poor, and silt, dust easily enter in the bearing, causes the stuck of bearing, causes the service life of carrying roller shorter.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved many sealing idler rollers that have, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide many sealing idler rollers of a kind of simple in structure, good sealing effect and long service life.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of many sealing idler rollers, and it comprises roll body, rotating shaft, bearing, bearing seat, seal ring, interior labyrinth packing, outer labyrinth packing, inner shield ring, outer back-up ring, seal disc and end cap; Wherein, described bearing seat is installed on respectively the two ends of roll body; Described bearing is contained in the bearing seat; Described rotating shaft support is on bearing; Be provided with described seal ring in the inboard of described bearing, the outside is provided with described interior labyrinth packing, outer labyrinth packing, seal disc and end cap successively; Described inner shield ring, the clamping of outer back-up ring phase, and be connected between end cap and the seal disc.
Many sealing idler rollers of the present utility model further are set to: described bearing, seal ring, interior labyrinth packing, outer labyrinth packing, inner shield ring, outer back-up ring and seal disc all are contained in the bearing seat.
Many sealing idler rollers of the present utility model also are set to: be provided with a packing ring between described end cap and the outer back-up ring.
Compared with prior art, the utlity model has following beneficial effect: many sealing idler rollers of the present utility model are by arranging the hermetically-sealed constructions such as seal ring, interior labyrinth packing, outer labyrinth packing and seal disc, thereby make the leak tightness of this carrying roller better, silt, dust are not easy to enter in the bearing, make the long service life of carrying roller.
Description of drawings
Fig. 1 is the part sectional view of many sealing idler rollers of the present utility model.
The specific embodiment
See also shown in the Figure of description 1, the utility model is a kind of many sealing idler rollers, and it is comprised of several parts such as roll body 1, rotating shaft 2, bearing 3, bearing seat 4, seal ring 5, interior labyrinth packing 6, outer labyrinth packing 7, inner shield ring 8, outer back-up ring 9, seal disc 10 and end caps 11.
Wherein, described bearing seat 4 is installed on respectively the two ends of roll body 1; Described bearing 3 is contained in the bearing seat 4; Described rotating shaft 2 is supported on the bearing 3.
Be provided with described seal ring 5 in the inboard of described bearing 3, the outside is provided with described interior labyrinth packing 6, outer labyrinth packing 7, seal disc 10 and end cap 11 successively.Described seal ring 5, interior labyrinth packing 6, outer labyrinth packing 7, inner shield ring 8, outer back-up ring 9 and seal disc 10 all are contained in the bearing seat 4.
Described inner shield ring 8, the 9 phase clampings of outer back-up ring, and be connected between end cap 11 and the seal disc 10.Further, be provided with a packing ring 12 between described end cap 11 and the outer back-up ring 9.
Many sealing idler rollers of the present utility model are by arranging the hermetically-sealed constructions such as seal ring 5, interior labyrinth packing 6, outer labyrinth packing 7 and seal disc 10, thereby make the leak tightness of this carrying roller better, and silt, dust are not easy to enter in the bearing 3, make the long service life of carrying roller.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
