Description

Technical Field

[0001] This utility model belongs to the field of spherical bearing disassembly technology, and specifically relates to a spherical bearing splitting device. Background Technology

[0002] Spherical plain bearings are sliding bearings with a special structure, mainly used in rotary motion applications that withstand angular changes or slight misalignment. They consist of an outer ring, an inner ring, and balls or sliding contact surfaces between them, capable of bearing radial loads, axial loads, and overturning moments. Spherical plain bearings are widely used in engineering hydraulic cylinders, forging presses, mining machinery, petrochemicals, shipbuilding, metallurgical rolling mills, and many other fields. During use, spherical plain bearings often require partial disassembly and replacement due to damage. Replacing the damaged parts individually reduces operating costs and prevents waste from complete scrapping. However, in common spherical plain bearings where the inner ring is internally connected to a shaft, disassembly often involves directly striking the inner ring to detach it from the shaft. In this disassembly process, the vertical force on the inner ring lacks a supporting structure, causing synchronous displacement between the inner ring and the shaft. This increases the difficulty of disassembly and, without a supporting structure, damages the inner ring during disassembly, increasing the overall scrap rate of the spherical plain bearing.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
