Briefly describe the design concept of carbon steel roller conveyor

The carbon steel roller loading conveyor adopts a structure in which the shaft is fixed on the outer support of the carbon steel roller. During transmission, only the cylinder and the bearing rotate, forming a transmission system that separates the main force and the transmission components. The design concept is to reduce the overall running resistance. In the design of the shaft, the oil injection hole is set at the shaft end, and the lubricating oil is injected through the internal passage of the shaft body; a seamless steel pipe sleeve is added to the outside of the shaft, and the two ends of the shaft sleeve are welded with the casting welding plate through the connecting plate to form the bearing, shaft and The seal is an integral sealing system. Carbon steel roller loading conveyor design features: 　　 1. The radial gap between the shaft sleeve and the shaft is 0.5-1mm, and the oil is injected from the oil cup at the shaft end to fill the gap between the shaft sleeve and the shaft. The gap between the shaft sleeve and the shaft sleeve can be formed The adsorption oil film can replenish the lubricating oil in the bearing and the sealed cavity at any time. After testing, the overall rotation resistance of the new carbon steel drum is about 40% lower than that of the ordinary carbon steel drum.　　2. The structure solves the problems that the shaft end and the bearing are easy to be misaligned when the large carbon steel drum is assembled, which causes the shaft step and the bearing inner ring to be scratched, which affects the service life of the parts, and wastes man-hours in assembly. The shaft sleeve assembly can be used for better alignment and easy installation. 3. The connecting plate adopts a cast-welded structure, and the connecting plate and the barrel are welded with a 'U'-shaped weld. In order to ensure the adhesion strength of the cast glue, the metal surface turning process thread of the barrel is reasonably designed after testing to ensure its technical requirements. 　　 4. The shaft sleeve has been treated with corrosion resistance, so that the inner wall of the barrel skin is isolated from the entire transmission system due to aging and external erosion, such as oxides and other impurities, which greatly extends the life of transmission parts such as shafts and bearings, and increases the carbon. The tightness of the steel drum.
