Summary:...
Planetary gear transmission is widely used in various industries due to its light weight, large load capacity and high efficiency. In view of the bearing characteristics of the planetary transmission, it is required that all components of the system have sufficient strength and reliability. So what caused the precision planetary reducer to fail?
When using a servo
precision planetary reducer, various equipment failures often occur. According to statistics, 80% of the failures of high-power planetary reducers are caused by gears, that is to say, the gear damage is caused by the planetary reducer. Therefore, the fundamental reason is that in daily management and operation, attention must be paid to the repair and maintenance of high-power gear reducers.
There are various forms of gear failure, and the cracks further develop and expand. There are many ways and forms of its failure form. Among these faults, more crack faults are more serious, and its fault mode can cause gear fatigue or even complete failure. Therefore, it is very important to analyze the failure mechanism of cracks and find out an effective fault diagnosis method for cracks.
The conventional diagnostic method is vibration spectrum analysis. This method is based on traditional vibration theory. Vibration data and waveforms are collected by the diagnostic instrument, analyzed and diagnosed, and the cause and location of the fault are determined. However, a sufficiently accurate fault model must be established to accurately identify vibration signals under fault conditions. The diagnostic staff has rich experience in fault diagnosis. The failure of the gearbox will directly affect the safe and reliable operation of the high-power precision servo reducer, and even paralyze the entire system. When using a planetary reducer, special attention should be paid to the maintenance of the gears to ensure that the gears are in normal condition.
