Description

Technical Field

[0001] The utility model relates to the technical field of spherical plain bearings, and particularly relates to a novel spherical plain bearing. Background Art

[0002] Spherical plain bearings are important mechanical components, mainly composed of an outer shell and an inner bearing. Spherical plain bearings have the characteristics of flexible rotation and can withstand large loads, and are widely used in fields such as construction machinery, mining machinery, and shipbuilding industry. The inner and outer rings of existing spherical plain bearings are usually designed very tightly to ensure their high load-bearing capacity and stability. However, this tight fit design makes the spherical plain bearings very difficult to disassemble. Due to the tight fit of the inner and outer rings, a large amount of force and special tools are required for disassembly, which is prone to deformation. During use, it may be affected by rust and dirt, and these attachments will increase the friction between bearing components, further increasing the difficulty of disassembly; and existing spherical plain bearings have complex structures and motion forms, including multiple raceways and friction points. In some parts, it is difficult for the grease to fully cover, resulting in these parts not being effectively lubricated. This may lead to increased local wear and shorten the service life of the bearing. Summary of the Invention
