To improve the accuracy and speed of fault diagnosis, it is necessary to improve the accuracy and speed of fault diagnosis. What are the characteristics of the micro-gear motor when it fails? The following is an introduction to the characteristics of the fault of the micro-gear motor.
1. Bearing peeling and pitting due to fatigue
2. The bearing has serious unbalance, bending and wiggling
3. The gear tooth engagement frequency and its harmonics are the carrier frequency, the gear shaft rotation frequency and its multiplier are the tooth engagement frequency modulation of the modulation frequency, and the vibration energy and envelope energy increase to a certain extent. When this phenomenon occurs When it indicates the fault of the tooth profile error of the micro gear reducer motor.
4. There is an impact-type vibration with a large amplitude, and the frequency is equal to the rotation frequency of the broken toothed shaft.
5. In the process of tooth engagement, when the gear turns to the pitting part to release, due to the sudden increase of friction force, one or several shocks will occur, and the tooth engagement vibration is modulated, and its frequency domain is manifested as a series of signals in the signal spectrum. Equally spaced frequency clusters. When this phenomenon occurs, it indicates that the micro-gear reduction motor has a failure of tooth surface pitting.
6. The vibration energy is very large, and the phenomenon of box resonance occurs.
7. The amplitude of the gear tooth engagement frequency and its harmonics increases significantly. The higher the order, the greater the amplitude of the amplitude increase, and the greater the increase in the vibration energy. This heralds the failure of uniform wear of the gears.
