Description

Technical Field

[0001] The utility model relates to the field of spherical roller bearings, in particular to a quickly replaceable spherical roller bearing outer ring connection mechanism. Background Art

[0002] Spherical roller bearings have two rows of rollers, which mainly bear radial loads, but can also bear axial loads in any direction. They have high radial load capacity and are particularly suitable for working under heavy loads or vibration loads, but cannot bear pure axial loads. The outer ring raceway of this type of bearing is spherical, so it has good self-aligning performance and can compensate for coaxiality errors. Spherical roller bearings are divided into two different structures according to the cross-sectional shape of the rollers: symmetrical spherical rollers and asymmetrical spherical rollers.

[0003] At present, spherical roller bearings are usually embedded in the inside of the bearing seat. However, it is troublesome to separate the spherical roller bearings from the bearing seat, which greatly reduces the replacement progress of the spherical roller bearings. In addition, the replacement process increases the workload of the staff and is not conducive to current use. Therefore, we propose a quick-replacement spherical roller bearing outer ring connection mechanism to solve the above problems. Utility Model Content
