A waterproof carrier roller comprises a roller shell, a shaft, a bearing, a first cover cap, a second cover cap, a protective cover and a retainer ring, wherein a sealing device is arranged between the second cover cap and a protective cover. Compared with the prior art, the utility model, improve at present ordinary bearing roller shroud and protective cover, improved the structure of original bearing roller shroud and protective cover, increase rubber seal device in the middle of, can play waterproof and prolong the effect of bearing life-span.

Description

Waterproof carrier roller

Technical Field

The utility model relates to a bearing roller, especially a waterproof bearing roller.

Background

At present, the carrier roller is widely applied to belt conveyors in various environments. Such as open-pit mines, underground coal mines, ports and docks, steel plants, cement plants and the like. In these environments, the device is applied to wet and watery conditions. Such as rainwater in strip mines and ports and docks, underground mining and transportation in coal mines, and the like. The gap is left between the inner side cover cap and the outer side protective cover of the common carrier roller, so that water can enter the carrier roller, the lubricating effect is reduced, the bearing is damaged, and the service life of the carrier roller is shortened. Therefore, a novel waterproof carrier roller which can be normally used in a humid and watery environment and has a long service life is needed to be designed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the carrier roller with a waterproof structure.

The utility model adopts the following technical scheme:

a waterproof carrier roller comprises a roller shell, a shaft, a bearing, a first cover cap, a second cover cap, a protective cover and a retainer ring, wherein a sealing device is arranged between the second cover cap and a protective cover.

Compared with the prior art, the utility model, improve at present ordinary bearing roller shroud and protective cover, improved the structure of original bearing roller shroud and protective cover, increase rubber seal device in the middle of, can play waterproof and prolong the effect of bearing life-span.

The utility model discloses a preferred scheme is:

one end of the sealing device, which is in contact with the second cover cap, is of a conical ring structure, the contact end of the sealing device and the protective cover is of a cylindrical barrel structure, and the connecting end of the conical ring structure and the cylindrical barrel is the minimum end of the conical ring structure. And the contact type sealing is adopted, so that the sealing is safe and reliable, and the waterproof performance is good.

The mounting hole of the cover cap II provided with the protective cover is in an equal-diameter hole structure.

Detailed Description

The invention is explained in detail below with reference to the drawings and the detailed description.

In the embodiment, a waterproof structure of the carrier roller of the embodiment is shown; the utility model discloses a waterproof construction of bearing roller is in original ordinary bearing roller shroud and protective cover structural transformation design. A gap is reserved between the inner cover and the outer protective cover of the original common carrier roller. When the bearing roller was operated in the environment of moist watery, inside water can get into the bearing roller along the space, reduced lubricated effect, damaged the bearing, made the bearing early inefficacy, reduced the life of bearing roller.

This embodiment improves the original structure by providing a low friction rubber seal between the cover and the shield. Water is prevented from entering the roller. The carrier roller can be normally used in a humid and watery environment, the waterproof function of the carrier roller is realized, and the carrier roller has a long service life.

A waterproof idler roller, as shown in fig. 2, fig. 1, fig. 2 and fig. 3: the roller shell comprises a roller shell 1, a first cover cap 2, a second cover cap 3, a protective cover 4, an annular protrusion 401, a retainer ring 5, an outer labyrinth seal 6, a bearing 7, a shaft 8, an inner labyrinth seal 9, a sealing device 10, a conical ring-shaped structure 101, a cylindrical barrel structure 102 and a concave part 103.

A sealing device 10 is arranged between the second cover cap 3 and the protective cover 4; one end of the sealing device 10, which is in contact with the second cover cap 3, is of a conical ring-shaped structure 101, the contact end of the sealing device 10 and the protective cover 4 is of a cylindrical barrel structure 102, and the connecting end of the conical ring-shaped structure 101 and the cylindrical barrel structure 102 is the minimum end of the conical ring-shaped structure 101; the mounting hole of the second cover cap 3 provided with the protective cover 4 is in an equal-diameter hole structure. Because the conical ring-shaped structure 101 is connected with the cylindrical barrel structure 102 through the end with the smallest diameter, the concave part 103 formed between the conical ring-shaped structure 101 and the cylindrical barrel structure 102 is beneficial to further compressing the conical ring-shaped structure 101 and the second cover cap 3 under the pressure generated when water enters, so that the conical ring-shaped structure 101 and the second cover cap 3 are in close contact with each other, and when the carrier roller rotates, drainage is also more beneficial.

In the second embodiment, the original structure of the cover cap 3 (see fig. 1) is provided with the protective cover 4, the mounting hole is a non-uniform diameter hole with an upward protruding conical ring-shaped hole, and the original protective cover 4 is provided with the ring-shaped protrusion 401.

The utility model has the advantages that: 1. and the contact type sealing is adopted, so that the sealing is safe and reliable, and the waterproof performance is good. 2. The utility model relates to a simple structure, reasonable in design has increased the waterproof function of ordinary bearing roller, is applicable to ordinary many water working condition of humidity that the supporting roller is inapplicable all together.

Claims

1. The utility model provides a waterproof bearing roller, includes the roller shell, the axle, and the bearing, shroud one, shroud two, the protective cover, the retaining ring, its characterized in that: a sealing device is arranged between the second cover cap and the protective cover; one end of the sealing device, which is in contact with the second cover cap, is of a conical ring structure, the contact end of the sealing device and the protective cover is of a cylindrical barrel structure, and the connecting end of the conical ring structure and the cylindrical barrel is the minimum end of the conical ring structure.
