In industrial production, the motor is a very common equipment, but the equipment will inevitably encounter wear problems during use. This is inevitable. Among the many accessories of the motor, the motor shaft is relatively easy to wear, so how to repair it ? Here are a few common methods
1. Interference-welding method
This repair method can be used when the motor shaft is slightly worn. This method is commonly used in the early days. The repair is faster. Install the shaft sleeve on the shaft journal through interference, and install a few fixed pins on the surface to make The pin and the sleeve are stabilized after being welded. If the wear is more serious, then this method is obviously not applicable.
2. Glue bonding method
Apply magnesium special iron glue on the surface of the shaft journal, heat the shaft sleeve, and bond it through the temperature curing of the shaft sleeve. The motor shaft repaired by this method has good performance and reliable connection. If the wear is not serious, then the above introduced The combination of the surplus welding method and the glue bonding method can ensure concentricity and high accuracy, but the operation is a bit troublesome, and the two need to be well coordinated.
3. Glue injection bonding method
This method uses transition and hot-fitting bushings, waits until it has cooled down, and then performs concentricity matching requirements, and then glues and bonds. In order to ensure the smooth communication of oranges when injecting glue, a spiral groove can be opened in the sleeve. This repair method is relatively simple, and can generally be repaired in one go.
The above are the three methods for repairing motor shaft wear. Each repair method has its own adaptability. Therefore, you can choose which repair method to take based on the wear of the electromechanical shaft.
