The installation method of bearing installation is very important. Improper installation may endanger the service life and performance of equipment or spindle bearings. So if the bearing is installed improperly, how should we dismantle the bearing? The editor will answer for you next. 1. Pushing method: Use a press to push and disassemble the angular contact ball bearing, which is stable and reliable, and will not damage the machine and the bearing shielding machine room. Presses are divided into manual push presses, hydraulic presses and mechanical presses. Matters needing attention: When the bearing is disassembled, the force point of the press should be on the center point of the shaft, and the pressure should not be biased. 2. Knocking method: The knocking force should not be applied on the rolling body or the cage of the bearing, but should be applied to the inner ring of the bearing. This method of disassembling the bearing is convenient and easy to operate, but it may damage the bearing. When the bearing is located at the end of the shaft , Use a copper rod or similar soft metal object lower than the inner diameter of the bearing to bear against the bearing end cover, add a protective layer pad under the bearing, and gently tap it with a hammer to remove it. Matters needing attention: When using this method to disassemble the bearing, it should be noted that the protective layer pad should be placed in a proper position, and our force point should be appropriate. 3. Pull out method; When installing the outer side of the bearing, the corner of the puller should be stretched outward; when assembling the inner ring, the puller should be stuck inwardly on the inner ring. Things to pay attention to: 1. The hook of the puller should be hooked on the inner ring of the bearing, not on the outside, so as to prevent the bearing from being loose or damaged during the disassembly process; 2. When disassembling the bearing with the puller, use The ball screw points to the core hole of the shaft and cannot be tilted. Also pay attention not to damage the hook and bearing, and pay attention to the force between the bearing and the hook; 3. During the disassembly of the bearing, pay attention to avoid dislocation of the hook; 4. The legs of the puller should be lower than 90. The above are the more common bearing disassembly methods summarized by engineers. In fact, during the design of bearings, it is necessary to fully consider the convenience of assembly in advance, and it is also very important to make special tools for assembly according to actual needs. When assembling, scientifically study the assembly method and order according to the drawings drawn, and investigate the mutual cooperation conditions of the bearings, so as to ensure the safety of the assembly work. If it is necessary to disassemble, follow the above methods to ensure that the bearings are not damaged to the greatest extent.
