1. The tapping force is generally applied to the inner ring of the bearing. The knocking force of the shielding room should not be added to the rolling elements and cage of the bearing. This method is simple and easy, but it easily damages the bearing when the bearing is at the end of the shaft. When using a copper rod or other soft metal material that is smaller than the inner diameter of the bearing, the shaft end is pressed against the shaft end, and the lower part of the bearing is padded, and the hammer is gently tapped with a hammer to remove it. Apply this method should pay attention to the position of the spacer should be appropriate, the focus should be correct.
2. Thermal Disassembly Method Used to remove the tight fit bearing. First, the oil heated to about 100 °C is poured into the bearing to be dismantled. After the bearing ring is thermally expanded, the bearing can be pulled out with a puller.
3. Pushing method Pressing the bearing with a press makes the work stable and reliable, and does not damage the machine and the bearing shielding machine room. The press has manual pushing, and the mechanical or hydraulic press pushes.
Matters needing attention: the focus of the press should be on the center of the shaft, and should not be biased.
4. Pull-out method Use a special puller. When disassembling, the bearing will be pulled out slowly as long as the handle is rotated. When the outer ring of the bearing is disassembled, the angle of the two legs of the puller should be opened outwards; when the inner ring of the bearing is removed, the two legs of the puller should be inward and snapped onto the end face of the inner ring of the bearing.
