Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] Such as figure 1 As shown, the combined cage type four-row cylindrical roller bearing includes two double raceway outer rings 5, three outer retaining rings, two inner rings 2, cage cover 3, roller 6, cage seat 7 and screws 8, where the three outer retaining rings include two first outer retaining rings 1 and one second outer retaining ring 4 . After the roller 6 is loaded into the pocket hole of the cage seat 7, cover the cage cover 3, and assemble the roller 6, the cage seat 7 and the cage cover 3 through screws 8 to form a cylindrical roller assembly; After the assembled cylindrical roller assembly is loaded into the two double raceway outer rings 5, the two ends are respectively blocked by two first outer retaining rings 1 and the second outer retaining ring 4; the two inner rings 2 are respectively installed into the cylinder in the roller assembly.

Abstract

The invention relates to a novel combined retainer type four-line column roller bearing mainly applied to rollers of rolling mills in the steel industry. The traditional bearing applied to the rollers of the rolling mills in the steel industry is a four-line column roller bearing in an original tree branch type retainer structure and is used for bearing radial loads. Due to the structural characteristics of the bearing, the bearing has inconvenient installation, and rollers often fall off so that the bearing is difficult to install and replace. Adopting an integrated and combined structure formed by a retainer and the rollers, the invention not only favorably satisfies the requirements of radial loads, but also solves the problems of difficult installation and replacement, and the like.

Description

technical field [0001] The invention relates to a novel combined cage type four-row cylindrical roller bearing mainly used in the iron and steel industry for rolling mill rolls. Background technique [0002] The traditional four-row cylindrical roller bearings used in the steel industry for rolling mill rolls are four-row cylindrical roller bearings with a dendritic cage structure to withstand radial loads. Due to the structural characteristics of the bearing, the installation of the bearing is very inconvenient, the rollers often fall off, the installation is difficult, and it is not easy to replace. Contents of the invention [0003] In order to overcome the problems of difficult bearing installation and difficult replacement, the invention provides a combined cage type four-row cylindrical roller bearing. [0004] The technical solution of the present invention: combined cage type four-row cylindrical roller bearing, including a first outer retaining ring 1, an inner r...
