Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a spherical roller bearing which is easy to install. Background Art

[0002] A spherical roller bearing is a bearing with double rows of rollers. Its outer ring features a common spherical raceway, while the inner ring has two raceways inclined at an angle relative to the bearing axis. This design gives the bearing self-aligning properties, automatically adjusting for shaft misalignment caused by shaft or housing deflection or misalignment. This makes the bearing less susceptible to shaft-to-housing misalignment or shaft bending. Spherical roller bearings are primarily used in metallurgy, papermaking, heavy machinery, and rail transportation.

By setting a plug rod and a socket, the plug rod can connect the spherical roller bearing, the first arc plate and the second arc plate. The socket can limit the plug rod, and the plug rod limit can position the spherical roller bearing.

[0004] In the above technical solution, the bearing is positioned and installed by using the cooperation of the insertion rod and the insertion hole. However, when the bearing is used on the equipment after installation, iron chips will be splashed onto the roller surface of the bearing due to external equipment such as cutting, resulting in reduced stability of the bearing installation and use.
