Since the birth of the LED lighting industry, it has received much attention. After several years of explosive development, it is accompanied by various doubts. The overcapacity of production capacity in the industry, the lack of standards, the lack of core technologies, and the uneven quality of products have been criticized in the industry. After the twists and turns, it entered 2013, and the industry's development gradually improved and was above the corner. Undoubtedly, the development of the industry in the past two years will have a major impact on the long-term development of the entire industry.
As the lighting industry of China's strategic emerging industries and pillar industries of energy conservation and emission reduction, the current situation can be described as difficult, and there are four major problems. First, there is no market for semiconductor lighting products in China; second, the current problems in the semiconductor lighting industry; third, how to solve the difficulties faced; Fourth, the development of the semiconductor lighting industry. As people in the industry, no matter how many difficulties we have in front of us, we still have to survive with a positive attitude, and we are worried about the responsibility of the industry for the country.
In the face of these problems in the lighting industry, we can consider breakthroughs in the following four aspects. The first is to change ideas and concepts, to constantly learn new technologies, new knowledge, and new ideas; the second is to embed the advanced concepts of the times into lighting products to fully meet the needs of the public; the third is to improve the technological content of applied products; the fourth is to reduce the cost of use. Input.
Three ideas for how to operate the industry. Imagine that the innovative concept of interoperating human and material information enables people and lighting products to form a harmonious relationship between people and things that coexist, serve each other and respect each other. Imagine two, implant scientific and technological content, and achieve product upgrades to fundamentally meet people's needs. Imagine three, replacing the public lighting products, replacing digital semiconductor lighting products with existing semiconductor lighting.
Conveyor pulleys are used on conveyors to support and deflect the belting through the conveyor structure. Conveyor pulleys also provide a mechanism whereby the conveyor belt can be trained to run (track) true along the conveyor idlers. Generally, pulleys are located at the ends of the conveyor structure and at the take-up arrangement. Pulleys are used to transmit the drive power into the conveyor belt and as such, are subjected to the dynamic belt tension forces in a conveyor.
Conveyor Pulley Components:
Drum or Shell:The drum is the portion of the pulley in direct contact with the belt. The shell is fabricated from either a rolled sheet of steel or from hollow steel tubing.
Diaphragm Plates: The diaphragm or end plates of a pulley are circular discs which are fabricated from thick steel plate and which are welded into the shell at each end, to strengthen the drum.
The end plates are bored in their centre to accommodate the pulley shaft and the hubs for the pulley locking elements.
Shaft:The shaft is designed to accommodate all the applied forces from the belt and / or the drive unit, with minimum deflection. The shaft is located and locked to the hubs of the end discs by means of a locking elements. The shaft and hence pulley shafts are often stepped.
Locking Elements:These are high-precision manufactured items which are fitted over the shaft and into the pulley hubs. The locking elements attach the pulley firmly to the shaft via the end plates.
Hubs:The hubs are fabricated and machined housings which are welded into the end plates.
Lagging: It is sometimes necessary or desirable to improve the friction between the conveyor belt and the pulley in order to improve the torque that can be transmitted through a drive pulley. Improved traction over a pulley also assists with the training of the belt. In such cases pulley drum surfaces are `lagged` or covered in a rubberized material.
Bearing: Bearings used for conveyor pulleys are generally spherical roller bearings, chosen for their radial and axial load supporting characteristics. The bearings are self-aligning relative to their raceways, which means that the bearings can be 'misaligned' relative to the shaft and plummer blocks, to a certain degree. In practical terms this implies that the bending of the shaft under loaded conditions as well as minor misalignment of the pulley support structure, can be accommodated by the bearing.
APPLICATION:
Spherical Roller Bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk conveyor pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
