Support roller bearing of high-accuracy wide and thick plate straightening machine

Abstract

The invention relates to a support roller bearing of a high-accuracy wide and thick plate straightening machine. The support roller bearing is characterized by comprising a support outer ring, a rotation shaft, roller pins, roller pin retaining racks, thrust ball bearings, retainer rings, seal rings and dustproof rings, wherein a concave opening is formed in the inner side of each of two end openings of the support outer ring; the rotation shaft is arranged in the support outer ring; 2-4 roller pin retaining racks are arranged on the rotation shaft; a plurality of roller pins are arranged on each roller pin retaining rack; one thrust ball bearing is arranged in the corresponding concave opening of the support outer ring; a retainer ring, a seal ring and a dustproof ring are arranged on a rotation shaft on the outer side of each thrust ball bearing in sequence from inside to outside; an oil injection hole is formed in one end of the rotation shaft and is used for injecting lubricants into the roller pins, the roller pin retaining racks and the thrust ball bearings. The support roller bearing has the advantages that the bearing is convenient to mount and use, the accuracy of produced plates can be improved, the service life is long and the structure is relatively compact.

Description

technical field [0001] The invention relates to a bearing, in particular to a support roller bearing of a high-precision wide and thick plate straightening machine. Background technique [0002] At present, the support roll of the wide and thick plate straightening machine used in the precision plate straightening machine includes a supporting outer ring, a rotating shaft, a number of backing bearings and a sealing cover; the backing bearing is set on the rotating shaft, and the supporting outer ring is set on a number of straightening machines. On the outer side of the bearing, a sealing cover is installed at both ends of the supporting outer roll; before the support roll of the wide and thick plate straightening machine is used, the supporting outer ring, rotating shaft, several straightening machine bearings and sealing covers must be assembled on site. The installation is cumbersome; and because there are several straightener bearings in the supporting outer ring, each b...

Problems solved by technology

[0002] At present, the support roll of the wide and thick plate straightening machine used in the precision plate straightening machine includes a supporting outer ring, a rotating shaft, a number of backing bearings and a sealing cover; the backing bearing is set on the rotating shaft, and the supporting outer ring is set on a number of straightening machines. On the outer side of the bearing, a sealing cover is installed at both ends of the supporting outer roll; before the support roll of the wide and thick plate straightening machine is used, the supporting outer ring, rotating shaft, several straightening machine bearings and sealing covers must be assembled on site. The installation is cumbersome; and because there are several straightener bearings in the supporting outer ring, each backing bearing cannot be assembled with the supporting outer ring and the rotating shaft with high precision, so that the straightening machine bearing and the supporting outer ring and the rotating shaft cannot be assembled with high precision during use. The rotating shaft is easy to wear and affect the production quality of precision plates. At the same time, it is cumbersome to disassemble and repair the backing bearing from the support ring of the wide and thick plate leveler after the backing bearing is worn.
