The dynamic balancing debugging of motor shaft new energy automobile is an important part to ensure the smooth operation of the motor, reduce vibration and noise, and extend the life of the motor. The following are the specific steps for the dynamic balancing debugging of motor shaft new energy automobile:
1. Preparation
First, you need to prepare professional dynamic balancing test equipment, such as a dynamic balancing machine. Check the appearance of the motor shaft to ensure that there is no obvious damage or deformation. At the same time, clean the impurities and oil on the surface of the motor shaft to avoid affecting the test accuracy.
2. Install the motor shaft
Install the motor shaft on the dynamic balancing machine, ensure that the installation is firm and the center line of the shaft coincides with the rotation axis of the dynamic balancing machine. Be careful to avoid bending or twisting of the shaft during installation to avoid affecting the test results.
3. Initial test
Start the dynamic balancing machine and let the motor shaft rotate at a certain speed. The dynamic balancing machine will detect the imbalance of the shaft during rotation, including the size and position of the imbalance. The initial test can obtain basic information about the imbalance state of the shaft.
4. Determine the position and size of the imbalance
According to the detection results of the dynamic balancing machine, determine the position and size of the imbalance on the motor shaft. Usually, imbalance will appear as the weight of the shaft being too heavy or too light at a specific position. The position of the imbalance can be marked on the shaft for subsequent adjustment.
5. Adjusting the imbalance
According to the position and size of the imbalance, take appropriate adjustment measures. Common adjustment methods include adding or removing balancing blocks, performing local processing, etc. If the imbalance is small, you can add balancing blocks at specific positions on the shaft and achieve balance by adjusting the weight and position of the balancing blocks. If the imbalance is large, you may need to perform local processing on the shaft to remove excess material to achieve balance.
6. Retest
After making adjustments, start the dynamic balancing machine again to test the motor shaft. Check whether the imbalance is within the allowable range. If the imbalance is still beyond the standard, repeat the adjustment steps until the requirements are met.
7. Verification and Recording
When the imbalance of the motor shaft meets the requirements, perform the final verification test. Ensure that the motor shaft can maintain a good balance at different speeds. At the same time, record the data during the adjustment process, including the position, size, adjustment method and final balance state of the imbalance, for subsequent reference and quality traceability.
In short, the dynamic balancing and debugging of motor shaft new energy automobile requires professional equipment and technology. Through precise testing and adjustment, it can ensure that the motor shaft can maintain balance when rotating at high speed and improve the performance and reliability of the motor.
