The installation method of the bearing is very important. Improper installation may endanger the service life and performance of the equipment or the main shaft bearing. So if the bearing is installed improperly, how should we disassemble the bearing? I will answer you next. 1. Pushing method: Use a press to push and remove the angular contact ball bearing, which is stable and reliable, and will not damage the machine and the bearing shielding 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 it should not be biased. 2. Knock method; The knock force should not be applied to the rolling body or cage of the bearing, but should be applied to the inner ring of the bearing. This bearing disassembly method 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 against the bearing end cover, add a protective layer pad under the bearing, and tap it gently with a hammer to remove it. Matters needing attention: Using this method to disassemble the bearing should pay attention to the protective layer pad should be placed in a suitable position, and our force point should be appropriate. 3. Pull out method; When installing the outer side of the bearing, the bent corner of the puller should be stretched out; when assembling the inner ring, the puller should be stuck inward on the inner ring. Matters needing attention: 1. The hook of the puller should be hooked on the inner ring of the bearing, but not on the outer side, so as to prevent excessive loosening or damage during the disassembly of the bearing; 2. When disassembling the bearing with the puller, make sure that 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 the dislocation of the hook; 4. The legs of the puller should be lower than 90 degrees. The above are the more common bearing disassembly methods summarized by engineers. In fact, during the bearing design, it is necessary to fully consider the convenience of assembly in advance. It is also very important to make special tools for assembly according to actual needs. When assembling, scientifically research the assembly method and sequence according to the drawn drawings, and investigate the mutual cooperation standard of the bearing to obtain a foolproof assembly work. If the above method is required to be disassembled, the bearing can be guaranteed to the greatest extent from damage.
