Abstract

The utility model discloses a roller of a belt conveyor. The roller of the belt conveyor comprises a pipe and a shaft arranged inside the pipe, wherein two bearing seats are respectively arranged at two ends inside the pipe, the shaft is inserted inside the two bearing seats, rolling bearings are installed on the bearing seats, a seal ring is arranged between each bearing seat and each rolling bearing in a clamping mode, sawtooth-shaped inner seal rings are arranged on the outer sides the rolling bearings, outer seal rings are interlaced and connected with the inner seal rings in a clamping mode, and check rings are arranged on the outer sides of the outer seal rings. According to the roller of the belt conveyor, the seal rings are arranged in front and at the back of the connection positions of the bearings, meanwhile, the check rings are arranged, so that water, dust and steam are prevented from entering the bearing seats, and the problem that due to the fact that the sealing function of the roller loses effects, the service life cycle of the roller is short is solved.

Description

A kind of band conveyor roller

Technical field

The utility model relates to a kind of band conveyor roller, belongs to the band conveyor accessory.

Background technology

Roller on the band conveyor is to be used for the material that carried on support belt and the load-transfer device, guarantees the device of load-transfer device smooth operation, is one of vitals in the feedway, also is the parts that very easily damage.The quality of roller directly has influence on the power consumption of normal operation, service life and the motor of band conveyor.Existing roller mostly is made up of roller body, axle, bearing, bearing seat and sealing member etc., but, the life-span of roller is still very low in production reality, major cause is that the band conveyor working environment is relatively poor, and the sealing property of roller is bad, causes in the annular seal space of roller and enters dust or steam, cause deterioration of lubricant to lose efficacy until bearing failure, the carrying roller load-carrying capacity is diminished, and shorten service life, causes bigger economic loss to enterprise.

The utility model content

The purpose of this utility model is to provide a kind of band conveyor roller, to solve the problem of existing Idler bearing sealing effectiveness difference, causes advancing dust or steam, the problem that deterioration of lubricant lost efficacy in the annular seal space of roller.

For achieving the above object, the technical solution of the utility model is:

A kind of band conveyor roller, comprise pipe, the axle of tube interior, the tube interior two ends respectively are provided with a bearing seat, and described axle is inserted in two bearing seats, and antifriction-bearing box is installed on the bearing seat, be arranged with seal ring between described bearing seat and the antifriction-bearing box, described antifriction-bearing box arranged outside has the serration inner seal ring, is connected with exterior seal ring with inner seal ring is staggered, and described exterior seal ring arranged outside has back-up ring.

The beneficial effects of the utility model are: the utility model all is provided with seal ring before and after the bearing connecting portion, be provided with simultaneously back-up ring again, stoped water, dust and aqueous vapor to enter in the bearing seat, thoroughly solved roller owing to seal failure causes short problem of roller cycle in service life.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model A place enlarged drawing.

Among the figure: antifriction-bearing box 1, pipe 2, axle 3, bearing seat 4, seal ring 5, inner seal ring 6, exterior seal ring 7, back-up ring 8.

The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment:

As shown in Figure 1 and Figure 2, a kind of band conveyor roller, comprise pipe 2, pipe 2 in-to-in axles 3, pipe 2 inner two ends respectively are provided with a bearing seat 4, described axle 2 is inserted in two bearing seats 4, antifriction-bearing box 1 is installed on the bearing seat 4, is arranged with seal ring 5 between described bearing seat 4 and the antifriction-bearing box 1, described antifriction-bearing box 1 arranged outside has serration inner seal ring 6, be connected with exterior seal ring 7 with inner seal ring 6 is staggered, described exterior seal ring 7 arranged outside have back-up ring 8.

The utility model is in application process, owing to before and after the bearing connecting portion, all be provided with seal ring, simultaneously be provided with back-up ring again, stoped water, dust and aqueous vapor to enter in the bearing seat, therefore can thoroughly solve roller owing to seal failure causes short problem of roller cycle in service life.

Claims

1. band conveyor roller, comprise pipe (2), pipe (2) in-to-in axle (3), the inner two ends of pipe (2) respectively are provided with a bearing seat (4), described axle (3) is inserted in two bearing seats (4), antifriction-bearing box (1) is installed on the bearing seat (4), it is characterized in that: be arranged with seal ring (5) between described bearing seat (4) and the antifriction-bearing box (1), described antifriction-bearing box (1) arranged outside has serration inner seal ring (6), be connected with exterior seal ring (7) with inner seal ring (6) is staggered, described exterior seal ring (7) arranged outside has back-up ring (8).
