Abstract
The utility model relates to a carrier roller bearing combined type seal structure which comprises a steel pipe, a shaft, bearing bases, bearings, an inner seal ring, an inner retainer ring, an inner labyrinth seal an outer labyrinth seal, a dustproof ring, an outer seal ring, a flat washer and an outer retainer ring. The bearing bases are respectively installed at two ends of the steel pipe. The bearing is contained in the bearing base. The bearing supports the shaft. The inner seal ring is arranged in the inner side of the bearing. The inner retainer ring, the inner labyrinth seal, the outer labyrinth seal, the dustproof ring and the outer seal ring are sequentially arranged on the outer side of the bearing. The flat washer is connected with the outer seal ring in an abutted mode. The outer retainer ring is clamped on the shaft and connected with the flat washer. Due to the fact that the labyrinth seal structure is adopted, the carrier roller bearing combined type seal structure is simple in assembling and good in seal performance. At the same time, due to the fact that seal materials of the carrier roller bearing combined type seal structure are nylon materials, rotational inertia is greatly reduced.
Description
Technical field
The utility model relates to a kind of constituent elements of belt conveyer, is specifically related to a kind of Idler bearing combined seal structure, belongs to the coal transport equipment technical field.
Background technology
Carrying roller is the important composition parts of belt conveyer, needs it to have the performances such as waterproof and dustproof, corrosion prevention corrosion, resistance to abrasion.At present, industry adopts the thickness that increases tube wall usually, in the hope of improving the friction durability of carrying roller, but this method not only sealing problem does not solve, increased again the rotor inertia of carrying roller, and carrying roller accessory bearing is stuck and lost efficacy, and also can cause the severe wear of adhesive tape, the loss of the energy, pollution and the various potential accident potential of noise.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved Idler bearing combined seal structure that has, 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 a kind of good airproof performance, the Idler bearing combined seal structure that rotor inertia is little.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of Idler bearing combined seal structure, and it comprises steel pipe, axle, bearing seat, bearing, inner seal ring, inner shield ring, interior labyrinth packing, outer labyrinth packing, dust ring, exterior seal ring, flat gasket and outer back-up ring; Wherein, described bearing seat is installed on respectively the two ends of steel pipe; Described bearing is contained in the bearing seat; Described axle is supported on the bearing; Be provided with described inner seal ring in the inboard of described bearing, the outside of bearing is provided with inner shield ring, interior labyrinth packing, outer labyrinth packing, dust ring, exterior seal ring successively; Described flat gasket is connected on the described exterior seal ring; Described outer back-up ring is fastened on the axle, and the described flat gasket of butt.
Idler bearing combined seal structure of the present utility model further is set to: described exterior seal ring is two-layer, and itself and bearing seat, axle are interference fit.
Idler bearing combined seal structure of the present utility model further is set to: described inner seal ring, interior labyrinth packing, outer labyrinth packing, dust ring, exterior seal ring are nylon material.
Compared with prior art, the utlity model has following beneficial effect: Idler bearing combined seal structure of the present utility model adopts labyrinth seal structure, makes assembling simple, good airproof performance; Simultaneously, its leakproofing material is nylon material, has significantly reduced rotor inertia.
