Abstract

The utility model discloses a compound high-intensity wear-resisting ceramic carrying idler, which comprises a roller cylinder (1), a bearing seat cover (3), a bearing seat (4), a bearing (5), a rotary shaft (2), an inner sealing ring (6) and an outer sealing ring (7). The roller cylinder (1) is made of high-intensity wear-resisting ceramics, the bearing seat cover (3) is arranged in two ends of the roller cylinder, the bearing seat cover employs the ABS injection pressure to mold and forms an integrated body with the roller cylinder, the bearing seat (4) is fixed in the bearing seat cover, the inside of the bearing seat is sequentially provided with the bearing (5), the inner sealing ring (6) and the outer sealing ring (7), and the inner sealing ring and the outer sealing ring are both labyrinth sealing rings. In the utility model, the carrying idler is compounded by three materials like ceramics, plastics and steel, the wear-resisting performance is not only high, but also the service life is long, the working efficiency of the carrying idler is increased, the working cost of the carrying idler is lowered, water-proof and dust-proof sealing performances are good, the bearing is not easy to oxygenize and rust, the rotating action is flexible and the serviceability is high. The carrying idler is applicable to working under the environment of heavier water-cement portions such as quay and mine.

Description

Combined type high-strength abrasion-proof carrier roller

Technical field

The utility model relates to the band conveyor parts, especially relates to the carrying roller on the band conveyor.

Background technology

As everyone knows, band conveyor is that a kind of operational throughput is big, and the transport efficiency height carries cost low, and have free from dust, noise low, be not subjected to effects limit such as topography and geomorphology, climate and environment, can realize transmission equipment remote, that long-time continuous is carried.At the band conveyor middle idler roller is the parts of an important key, and the service life of carrying roller and work effect are transmission efficiency and the job costs that are directly connected to band conveyor.The tradition carrying roller is mostly made processing with steel pipe as roller, though it is comparatively convenient that carrying roller is made, installed and changes, but conventional rollers in use also has following weak point: the one since with belt conveyor surface that the steel roller surface contacts on residual bur arranged, this bur and steel roller surface produce friction for a long time, make the wearing and tearing fast easily of steel roller surface, also might cause belt to cut open the chest to tear, influence the transmission efficiency of carrying roller, shortened the service life of carrying roller; The 2nd, each part assembling concentricity of carrying roller is not high, and roller revolving resistance is bigger, has reduced the driving efficiency of carrying roller; The sealing arrangement dustproof and waterproof performance that is traditional carrying roller employing again is not very good, carrying roller is for a long time under the heavier environment of water ash such as harbour, mine and mining, be subjected to the influence of corrosion oxidation material and water ash, oxidation that causes easily and corrosion, cause carrying roller distortion and stuck, make the carrying roller cisco unity malfunction, increased the band conveyor job costs.

The utility model content

At the problem that above-mentioned prior art middle idler roller exists, the utility model provides a kind of not only the manufacturing that the equally all very convenient and water proof and dust proof leak tightness height of replacing, long service life, the good again combined type high-strength abrasion-proof carrier roller of work effect are installed.

The technical scheme that the technical problems to be solved in the utility model is taked is: described combined type high-strength abrasion-proof carrier roller comprises roller, bearing sleeve, bearing seat, bearing, rotating shaft, inner seal ring and exterior seal ring, described roller is made with the high-strength abrasion-proof pottery and is formed, described bearing sleeve is positioned at roller inner chamber two ends, described bearing sleeve forms integral body with the ABS injection moulding and with roller, described rotating shaft two ends extend out to outside the roller two ends, bearing seat is passed in rotating shaft, bearing seat is fixed in the bearing sleeve, in bearing seat, be disposed with bearing, inner seal ring and exterior seal ring, described inner seal ring and exterior seal ring are the labyrinth seal circle.

Described inner seal ring and exterior seal ring adopt polyamine fat or ABS to make and form, and described bearing seat adopts the accurate machine compacting of steel to make and forms, and described bearing is the carrying roller special bearing.

The utility model is owing to be provided with the bearing sleeve with roller formation single-piece ABS in the ceramic roller of high-strength abrasion-proof, make the coaxial processing of they energy, guarantee to process concentricity, and in bearing seat, be provided with radially lip seal circle of inside and outside dual labyrinth, thereby form porcelain, mould, three kinds of compound carrying rollers of material of steel.The utility model is the resistance to abrasion height not only, long service life, service life improved at least 5 times or more than traditional carrying roller more than 10 years its service life, and carrying roller water proof and dust proof sealing property height, be difficult for oxidation and corrosion, the running flexible movements, the carrying roller good working effect, thereby can improve the work efficiency of carrying roller, reduce the job costs of carrying roller, can be useful in work under the heavier environment of water ash such as harbour, mine and mining.
