1. The knocking force is generally applied to the inner ring of the NSK bearing. The knocking force of the shielding machine room should not be applied to the rolling elements and cages of the bearing. This method is simple and easy to implement, but it is easy to damage the bearing. When the bearing is located at the end of the shaft When the bearing is installed, use a copper rod or other soft metal material smaller than the inner diameter of the bearing against the shaft end, add a spacer to the lower part of the bearing, and tap lightly with a hammer to remove it. When applying this method, attention should be paid to the proper placement of the pad and the correct focus point.
2. Hot disassembly method It is used to disassemble the tightly fitted bearing. First, pour the oil heated to about 100 ℃ on the bearing to be disassembled with an oil can. After the bearing ring is heated and expanded, the bearing can be pulled out with a puller.
3. Pushing method Push the bearing with a press, and the work is stable and reliable, without damaging the machine and the bearing shielding room. The press has manual push, mechanical or hydraulic press push.
Matters needing attention: The pressing point of the press should be on the center of the shaft, and should not be biased.
4. Pull-out method Using special puller, when disassembling, as long as the handle is rotated, the bearing will be slowly pulled out. When disassembling the outer ring of the bearing, the corners of the two legs of the puller should open outward; when disassembling the inner ring of the bearing, the two feet of the puller should be inward and clamped on the end face of the inner ring of the bearing.
