Abstract

The utility model discloses a water-proof, dust-proof, freeze-proof, wear-resistant and acid-and-alkali-resistant ceramic carrier roller, which comprises a roller cylinder (1), bearings (3), a central shaft (2) and seals (4), the roller cylinder is made of high-strength wear-resistant ceramic, the bearings are fixed in both ends of the cavity of the roller cylinder, the central shaft passes through the bearings and is extended out of both ends of the roller cylinder, the central shaft is a steel hollow shaft, and the seals are respectively arranged on the outsides of the bearings, and are framework oil seals. The utility model is characterized by waterproofness, dustproofness, freezeproofness, wear resistance, acid and alkali resistance, long service life and higher use environment adaptability. The utility model has the advantages of stable and reliable operation, little noise, convenient mounting and maintenance, high conveying efficiency, less maintenance cost and low operation cost.

Description

Three anti-two anti-carrier rollers

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, because it is big that band conveyor has operational throughput, the transport efficiency height, the conveying cost is low, and have that dust is few, noise is low, be not subjected to effects limit such as topography and geomorphology, climate and environment, can realize characteristics remote, that long-time continuous is carried, and be widely used in industries such as mine, chemical industry, smelting, building materials, electric power and harbour.Belt roller is the parts of an important key in band conveyor, and the service life of carrying roller and work effect are transmission efficiency and the job costs that are directly connected to band conveyor.Existing carrying roller in use also has following weak point: the one, though the roller of existing carrying roller adopts pottery manufacturing, but ceramic roll body intensity is not high, toughness is lower, roller surface is more coarse, residual on roller and the belt conveyor surface have bur to produce bigger friction, roller surface is worn and torn easily, roller ruptures easily, has reduced the transmission efficiency of carrier roller, has shortened the service life of carrier roller; The 2nd, the bearing felt performance of existing carrier roller is not high, carrying roller humidity, dust, low temperature freeze and the corrosion oxidation environment under use, can produce the phenomenon that serious corrosion, bearing are stuck easily, carrying roller runs improperly, make the carrier roller cisco unity malfunction; Solid axle is mostly adopted in the rotating shaft that is existing carrier roller again, can make rotating shaft produce distortion when carrying roller is stressed, and shaft strength is unbalanced, increases the rotational resistance of bearing, thereby has reduced the transmission efficiency of carrier roller, has increased the job costs of carrier roller.

The utility model content

At the problem that carrier roller in the above-mentioned prior art exists, the utility model provides a kind of applicability and practical, long service life, transmission efficiency height, the three anti-two anti-carrier rollers that job costs are low.

The technical scheme that the technical problems to be solved in the utility model is taked is: described three anti-two anti-carrier rollers comprise roller, bearing, center shaft and sealing member, described roller adopts the manufacturing of high-strength abrasion-proof stupalith, described bearing fixing is at roller inner chamber two ends, described center shaft passes bearing and extend out to outside the roller two ends, described center shaft is the steel hollow shaft, in the bearing arranged outside sealing member is arranged, described sealing member is an outside framework oil seal.

Described high-strength abrasion-proof stupalith roller is to add bauxite in the existing clay ceramics of making roller, makes aluminum content in its ceramic roller bring up to 40%wt by original 20%.

In making the carrier roller roller, increase roller polishing operation, improve the surface finish of roller, thereby reduced the wearing and tearing of roller surface, the radial runout that has reduced carrying roller and rotational resistance.

The utlity model has following characteristics:

1, resistance to abrasion is good, and is not easy to wear, and long service life has on average made the life-span more than 35000 hours, is 2-3 times of existing common carrying roller.

2, have three anti-be the characteristics of waterproof and dustproof, antifreeze and two anti-promptly wear-resistant, acid-alkali-corrosive-resistings, product environment applicability is stronger.

3, stable and reliable operation, noise is little, and I﹠M is convenient.

4, transmission efficiency height, service expenditure is few, and the operation job costs are low.

The specific embodiment

In Fig. 1, described three anti-two anti-carrier rollers, it comprises roller 1, bearing 3, center shaft 2 and sealing member 4, described roller 1 adopts the manufacturing of high-strength abrasion-proof stupalith, and aluminum content is 40%wt in the ceramic roller chemical analysis, and described bearing 3 usefulness sealants are fixedly mounted on roller inner chamber two ends, center shaft 2 passes bearing and extend out to outside the roller two ends, described center shaft is the steel hollow shaft, is provided with sealing member in the bearing outside, and described sealing member is an outside framework oil seal.

Claims

1. three prevent two anti-carrier rollers, it comprises roller (1), bearing (3), center shaft (2) and sealing member (4), it is characterized in that: described roller (1) adopts the manufacturing of high-strength abrasion-proof stupalith, described bearing (3) is fixed on roller inner chamber two ends, described center shaft (2) passes bearing and extend out to outside the roller two ends, described center shaft is the steel hollow shaft, in the bearing arranged outside sealing member is arranged, and described sealing member (4) is an outside framework oil seal.
