As the core supporting component of rotating machinery, the performance and condition of rotor bearings directly affect the operational stability and reliability of the entire equipment. For example, in the power generation industry, the rotor bearings of large steam turbine generator sets bear enormous loads, ensuring that the rotor maintains a stable position during high-speed rotation. Any bearing failure can cause the unit to shut down, resulting in huge economic losses. In aircraft engines, rotor bearings operate in harsh environments of high temperature, high speed, and high load, and are crucial to flight safety.
[0003] After long-term operation, the rotor bearing may be tightly bonded to the shaft neck or bearing seat due to wear, corrosion, high-temperature deformation, etc., and the rotor bearing needs to be disassembled. The traditional disassembly method is to use different tools to knock on the rotor bearing to loosen the rotor bearing to achieve the disassembly effect. If the knocking force is too small, the bearing cannot be disassembled smoothly; if the knocking force is too large, the bearing itself, the shaft neck or surrounding related components may be damaged, which brings inconvenience to the disassembly of the rotor bearing, thereby increasing the limitations of the rotor bearing disassembly.

The outer side of the movable column 52 is fixedly connected with a limited movable disk 53. A sliding groove 54 is opened inside the bottom of the L-shaped clamping plate 51.
[0025] As a technical optimization solution of the present invention, by providing a movable clamping assembly 5, the rotating bearing can be clamped to prevent the rotor bearing from being offset during disassembly and becoming unable to be disassembled.

[0029] As a technical optimization solution of the present invention, by providing the clamping area adjustment component 7, the clamping contact area between the L-shaped clamping plate 51 and the rotor bearing can be increased to prevent the rotor bearing from slipping due to a small clamping area.

When the rotor axis loses contact with the connecting piece of the clamping rotor bearing, the rotor bearing is disassembled and can be removed. When the contact area of the clamping rotor bearing needs to be adjusted, the rotating block 73 drives the adjusting screw 72 to rotate and drives the contact plate 71 to move inward to a suitable position. The clamping area adjustment is completed, thereby having the advantage of easy disassembly.
