Abstract

The invention relates to a combined bearing for a rolling mill. The combined bearing for the rolling mill comprises a double-row conical bearing, a sealing ring, a check ring and a bearing seat. The outer-diameter portion of the double-row conical bearing is directly inserted into the bearing seat. The check ring is arranged between the double-row conical bearing and the bearing seat and used for positioning and adjusting a bearing clearance. The sealing ring is arranged between an inner ring and an outer ring of the double-row conical bearing. Compared with the prior art, the combined bearing for the rolling mill has the advantages that installation maintenance is convenient, and the clearance can be adjusted conveniently.

Description

technical field [0001] The invention relates to a bearing, in particular to a combined bearing for a rolling mill. Background technique [0002] At present, multi-row tapered or cylindrical roller bearings are commonly used in the rolling mill industry. It is characterized by strong carrying capacity. But its disadvantages are: 1) installation is inconvenient and maintenance is difficult. The technical requirements for installers are high, resulting in waste of working hours. 2) It is difficult to adjust the preload and clearance. Contents of the invention [0003] The object of the present invention is to provide a combination bearing for rolling mills which is convenient for installation and maintenance and clearance adjustment in order to overcome the defects of the above-mentioned prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A combined bearing for a rolling mill, characterized in that ...
