Abstract

The invention belongs to the technical field of steel rolling equipment, and particularly relates to a roller bearing assembly structure. A roller is rotatably installed in a bearing seat through a cylindrical roller bearing and a tapered roller bearing; an axial positioning assembly is installed on the roller, and the cylindrical roller bearing and the tapered roller bearing are axially positioned through the axial positioning assembly; a first oil inlet channel and a second oil inlet channel are axially arranged in the bearing seat; and a plurality of annular oil grooves are formed in the wall of an inner hole of the bearing seat, the first oil inlet channel communicates with the annular oil grooves through a plurality of first branches, and the second oil inlet channel communicates withthe annular oil grooves through a plurality of second branches. With the roller bearing assembly structure, the problems about roller assembly in the prior art can be solved, and the problem of poorbearing lubrication effect caused by unreasonable lubrication channels at present is also solved.

Description

technical field [0001] The invention belongs to the technical field of rolling equipment, and in particular relates to a roll bearing assembly structure. Background technique [0002] As the width of steel strip produced by iron and steel enterprises becomes larger and larger, the size of the rolls of the corresponding rolling mills is also increasing. At the same time, the size of the bearings in the roll system is also increasing. Bearing radial force also needs to bear axial force, which puts forward higher requirements for its assembly structure. A more reasonable and stable assembly is enough. At the same time, the lubrication form of the bearing has become a problem that needs to be continuously improved. In the past small strip steel production line, due to the relatively small size of the bearings used, a single oil inlet (only one oil inlet hole is drilled on the bearing seat of the rolling mill) oil-air lubrication can meet the use requirements. But just can not s...
