As a product with frequent start, high speed ratio and stable operation, the utilization rate of precision motor shaft has been greatly improved. For the shaft, vibration and shock resistance are the basic requirements, because in many cases, heat treatment is required during processing. The surface hardness of the shaft is increased, and the wear resistance and vibration resistance are increased. However, sometimes people will have the problem of large vibration of the motor shaft during use. Why?
There are three main reasons for the large vibration of the precision motor shaft, mechanical equipment, electromechanical engineering and electromagnetic induction. Let the technicians of Sanyuan Machinery Factory analyze them one by one.
The rotor of the machine is in an unbalanced state, and it is not installed properly during installation, resulting in insufficient impact toughness. When the motor shaft is close to the use limit line, the vibration will continue to increase, and there will be noise during operation.
2. Mechanical And Electrical Engineering Mixed Aspects
The rotor of the motor shaft is not symmetrical due to its own force or magnetic center management, and the prosperous electromagnetic induction anti-tension force makes the motor shaft vibrate. Sometimes the situation is more serious, which can cause damage to the piston pin, and the piston pin will vibrate when the temperature rises rapidly. Intensify.
The power supply is unstable or the three-phase voltage is unbalanced, the grounding device has been broken down, the winding is disconnected, and the inter-turn penetration will cause the precision motor shaft to vibrate.
The above three points have introduced the reasons for the vibration of the precision motor shaft. In order to ensure the normal, stable and safe use of the motor shaft, each of the reasons mentioned above needs to be taken seriously.
