Disassembling bearings requires the same level of care as installing them. It's essential to avoid damaging the bearing or surrounding components, especially when dealing with interference fit bearings, which can be quite challenging to remove. Planning ahead during the design stage and understanding the disassembly process is crucial. Always refer to the drawings and check the bearing's fit conditions before starting.
Here are some effective methods for disassembling different types of bearings:
1. **Outer Ring Disassembly**:
For interference fit bearings, it’s recommended to pre-install several outer ring loosening screws around the outer casing. Tighten these screws evenly on one side, and while removing them, cover the screw holes with plugs. For tapered roller bearings and other separable bearings, make a few cuts on the outer shoulder of the housing and use a block and press to open them, or gently tap them to loosen.
2. **Inner Ring Disassembly (Cylindrical Bore Bearings)**:
The inner ring of standard cylindrical bore bearings can be removed using a hydraulic press. Ensure the inner ring is properly supported during the pulling process. For large bearings, an oil pressure method is often used, where oil is applied to the shaft to facilitate removal. Bearings with larger widths may require combined drawing and clamping devices.
For NU and NJ type cylindrical roller bearings, the induction heating method is effective. Heat the part briefly to expand the inner ring, then pull it off safely.
3. **Tapered Hole Bearings**:
These bearings are generally easier to disassemble than tight-fit sleeve bearings. Support the inner ring with a block fixed on the shaft, and turn the nut back several times. Then, strike the block with a hammer to remove the bearing.
For large tapered bearings, the oil pressure method is particularly useful. Apply oil through the oil hole on the conical shaft to expand the inner ring and remove the bearing. In some cases, the nut itself can act as a blocking tool.
