Integrated self-lubricating carrier roller structure for medium-thickness plate roller type cooling bed

Abstract

The invention relates to the technical field of manufacturing of high-performance, high-reliability, long-service-life sealing, transmission, fastening, hydraulic and pneumatic products or elements, in particular to an integrated self-lubricating carrier roller structure for a medium-thickness plate roller type cooling bed. The integrated self-lubricating carrier roller structure comprises a shaftand a shaft bushing, installation heads are arranged at two ends of the shaft, the shaft is connected to and installed on a cooling bed, and the shaft and the shaft bushing are integrally installed.One end of the shaft is a protruding baffle ring, the shaft bushing is flush with the baffle ring on the shaft, a section of external thread is machined at the other end of the shaft, a sealing ring is additionally arranged on the end face, a fixing nut is just screwed into the external thread, and the end face is sealed through the sealing ring. Round holes are evenly formed in the side face of the shaft bushing, lubricating blocks are fixed in the round holes, and the shaft bushing with the lubricating blocks plays a self-lubricating role. The integrated self-lubricating structural design isadopted, a compact rolling friction mode is kept all the time, metal ceramic is cladded on an abrasion face through the metal surface engineering technology for strengthening treatment, multi-stage sealing is achieved, dust is prevented from entering the structure, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical fields of high performance, high reliability and long life sealing, transmission, fastening, hydraulic and pneumatic products or components manufacturing, and in particular to an integrated self-lubricating idler roller used for medium and thick plate roller cooling beds structure. Background technique [0002] The rolling plate cooling bed is a cooling bed composed of circular rolling plates with the same diameter. The circular rolling plate (roller) is fixed on the shaft concentrically or eccentrically with the transmission shaft. The total cooling table is arranged in rows and staggered. Thick plate cooling equipment that moves on a rotating circular roller and is cooled by flowing air. The rolling plate cooling bed has the advantages of small scratches on the lower surface of the steel plate, high cooling efficiency, less faults, easy operation and maintenance, and low equipment investment.

Problems solved by technology

The traditional roller bushing is copper-based plus graphite molecules, and there is no adsorption capacity during the lubrication process. The release is too fast, and the lubrication effect is completely lost during the long-term sliding process, resulting in wear of the bushing, or even complete wear of the bushing. Direct friction between roller and shaft

The crux of the problem is that the bushing and the shaft are stuck due to insufficient lubrication between the bushing and the shaft, coupled with the thermal expansion of the slab, which eventually causes the jamming

In addition, due to the high-pressure, high-temperature and dusty working environment, dust can easily enter the device, which will also cause the shaft sleeve to be stuck and the gap between the shaft sleeve and the idler shaft to be too large

The jamming of idler rollers will cause problems such as strain and scratches on the finished slab, and increase the scrap rate
