High-performance corrosion-resistant non-metal carrier roller

Technical Field

The utility model relates to the technical field of carrier rollers, in particular to a high-performance corrosion-resistant nonmetal carrier roller.

Background

In the mining field, the bearing roller is a conveying part who often is used, and in material transportation process, erects the conveyer belt through a plurality of bearing rollers to rotate through the bearing roller with the conveyer belt with the material synchronous transportation at its top.

In view of the harsh environment in the mining field, the idler must have wear-resistant and corrosion-resistant characteristics, most of the existing idlers on the market are metal idlers, rubber idlers and nylon idlers, and the idlers have technical defects in the using process, for example, 1. The metal carrier roller is not corrosion-resistant, has larger weight and strong conductivity, is easy to generate static electricity, and has certain risk when being used in a mine; 2. the rubber carrier roller and the nylon carrier roller have certain corrosion resistance, but the two carrier rollers have higher manufacturing cost and cause certain production cost pressure for use units; 3. all the types of carrier rollers have the defect of heavy weight, and the defect directly causes high-power operation of driving equipment and high energy consumption; 4. the carrier rollers of all the types have no good sealing performance, and are easy to scrap due to impurities or water seepage in severe environments such as mines and the like.

To prior art's drawback, as this trade technical staff, how to improve current bearing roller, make it have light in weight, corrosion-resistant, the good advantage of leakproofness and have fine insulating nature to thoroughly solve the drawback in the prior art.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a high-performance corrosion-resistant nonmetal carrier roller.

The utility model provides the following technical scheme: a novel carrier roller is characterized in that a roller body is arranged to be of a symmetrical structure, a fixed shaft is arranged in the center of the roller body, a steel lining is sleeved on the outer side of the fixed shaft in a surrounding mode, counter bore bearing chambers are arranged at two ends of the steel lining, the fixed shaft penetrates through a counter bore in the center of each counter bore bearing chamber, a lining and a bearing are arranged in each counter bore, the inner diameter of each bearing is in interference fit with the outer diameter of the corresponding fixed shaft, and the outer diameter of each bearing is in interference fit with the inner diameter of each counter bore bearing chamber; an annular inner sealing ring is arranged on the outer side face of the bearing, and an outer sealing ring is inserted into the right side of the inner sealing ring.

Preferably, a layer of roller skin is coated outside the steel lining inner liner, and the roller skin is a non-metal composite flexible material layer.

Preferably, an inner blocking cover and an outer blocking cover are arranged on the outer sides of the inner sealing ring and the outer sealing ring.

Preferably, the outer diameter of the inner baffle cover is in interference fit with the roller skin.

Preferably, the outer blocking cover is fixed on the fixed shaft through a clamp spring.

Preferably, the inner sealing ring and the outer sealing ring are both irregularly shaped, and the inner sealing ring and the outer sealing ring are matched to form a labyrinth-shaped sealing area.

The utility model has the beneficial effects that: the left end and the right end of the roller body are provided with the counter bore bearing chambers, and the inner diameter of each counter bore bearing chamber is provided with the bearing, the inner sealing ring and the outer sealing ring; the inner sealing of the roller body is realized through the labyrinth-shaped sealing section, the waterproof and dustproof protection is realized through the combination of the inner blocking cover and the outer blocking cover, the fine dust and liquid entering the roller body are primarily protected, and the dust and the liquid are thoroughly blocked through the labyrinth-shaped sealing section.
