Tool for disassembling bearing outer ring of printing rubber roller

Abstract

The invention provides a tool for disassembling a bearing outer ring of a printing rubber roller, and relates to the technical field of printing machinery. The tool for disassembling a bearing outer ring of a printing rubber roller comprises a first ejection rod making contact with the bearing outer ring, a connector fixedly connected with the first ejection rod, a sleeving connection head connected with the connector in a telescopic mode, a second ejection rod fixedly connected with the sleeving connection head and making contact with the bearing outer ring, and an electric punching rod perpendicularly connected with the sleeving connection head. The diameter of the first ejection rod is larger than that of the connector. The bearing outer ring can be driven to be separated from the rubber roller, a rubber roller barrel and a rubber layer on the surface can be protected as much as possible, and the aim of not damaging the rubber layer of the rubber roller is achieved.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a tool for disassembling the outer ring of a printing rubber roller bearing. Background technique [0002] In the lithographic printing machine industry, the printing rubber roller of the printing unit is defined as a general wearing part. During the printing process, the rubber layer on the surface of the printing rubber roller is easy to wear and tear. At the same time, the supporting bearing of the rubber roller body will also be worn due to high-speed operation, the bearing cage will break, the inner ring of the bearing will come out, and the outer ring of the bearing will still be sleeved in the bearing hole of the rubber roller body. The outer ring of this kind of bearing is difficult to remove, which will make the rubber roller unusable. The usual method is to weld a rod on the outer ring of the bearing, and continuously tap the welded rod to drive the outer ri...

AI Technical Summary

Problems solved by technology

At the same time, the supporting bearing of the rubber roller body will also be worn due to high-speed operation, the bearing cage is broken, the inner ring of the bearing comes out, and the outer ring of the bearing is still set in the bearing hole of the rubber roller body

The outer ring of this kind of bearing is difficult to remove, which will cause the rubber roller to be unusable

The usual method is to weld a rod on the outer ring of the bearing, and continuously tap the welded rod to drive the outer ring of the bearing to vibrate, thereby driving the outer ring of the bearing to slowly come out of the rubber roller body. Although this method is commonly used, it takes a long time , and because the high temperature and spattered welding slag generated during welding are easy to damage the rubber layer of the rubber roller, resulting in damage to the rubber roller
