Rolling bearing with combined retainer

Abstract

The invention provides a rolling bearing with a combined retainer. The defect of the prior art of short service life of the bearing is overcome by the rolling bearing with the combined retainer. The rolling bearing with the combined retainer comprises an outer ring, an inner ring and rolling bodies which are assembled between the inner ring and the outer ring through the retainer. The rolling bearing is characterized in that at least two duplex retainers are served as the retainer for positioning through outer diameters of the rolling bodies so as to restrain at least three rows of rolling bodies in a same axial line; the axial lines of the rolling bodies in the same row are in the same axial line; and at least two duplex retainers and one single-linking retainer also can be used for positioning through the outer diameters of the rolling bodies and are connected through a pin hole, a pin shaft, an elastic sheet or bolt, so as to restrain at least four rows of rolling bodies on the bearing in the same axial line, and the axial lines of the rolling bodies on the same bearing are in the same axial line. The rolling bearing has the advantages of reasonable structural design, simple manufacturing process, high positioning precision, convenience in assembling and disassembling, and capabilities of obviously increasing the service life of the rolling bearing and the production efficiencies of rolling equipment and other equipment.

Description

technical field [0001] The invention relates to a rolling bearing, in particular to a rolling bearing with a combined cage that is positioned on the same bearing by at least two double-linked cages with the outer diameter of the rolling body and constrains at least three rows of rolling bodies on the same axis. It is mainly used in equipment such as rolling mills. Background technique [0002] Rolling bearings are widely used in rolling mills and other equipment, including single-row, double-row, three-row, four-row bearings, etc. In the high-speed and high-load operation of the bearing, due to the continuous alternating load of the bearing components, premature fatigue of the inner and outer rings of the bearing and the rolling elements often occur, resulting in a reduction in the service life of the bearing and frequent failures of rolling mills and other equipment , Increase the maintenance workload, thereby affecting the performance and production efficiency of rolling ...
