1. Pushing method Use a press to push the bearing, the work is stable and reliable, and the machine and the bearing shielding machine room are not damaged. The press has manual push, mechanical or hydraulic press push. Matters needing attention: The force point of the press should be on the center of the shaft, and it should not be biased. 2. The knocking force is generally applied to the inner ring of the bearing. The knocking force of the shielding machine room should not be applied to the rolling element and cage 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. 3. Pull-out method Using a special puller, when disassembling, as long as the handle is rotated, the bearing will be slowly pulled out. When disassembling the bearing outer ring, the corners of the two feet of the puller should be opened outward; when disassembling the bearing inner ring, the two feet of the puller should be inward and clamped on the end face of the bearing inner ring. Matters needing attention: 1. The hook of the puller should be hooked to the inner ring of the bearing, not the outer ring, so as to avoid excessive loosening or damage to the bearing; 2. When using the puller, align the screw rod with the center hole of the shaft , must not be skewed. Pay attention to the force of the hook and the bearing, and do not damage the hook and bearing; 3. Pay attention to preventing the hook from slipping; 4. The angle of the two feet of the puller is less than 90°. 4. 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. Matters needing attention: 1. First, the puller should be installed on the bearing to be dismantled, and a certain pulling force should be applied; 2. Before heating, wrap the shaft with asbestos rope or thin iron plate to prevent the shaft from expanding due to heat, otherwise it will It is difficult to disassemble. When removing the bearing from the bearing housing hole, only the bearing housing housing can be heated, but the bearing cannot be heated; 3. When pouring oil, the shielding machine room should pour the oil can smoothly on the bearing ring or rolling element. And put an oil basin under it to collect the hot oil that flows down to avoid waste and burns; 4. The operator should wear asbestos gloves to prevent burns.
