The solution of sudden failure of servo motor reducer

2021-08-12

There are many types of reducer used by servo motor, such as the more common servo motor reducer worm gear worm reducer, planetary reducer, hard tooth surface reducer. These three reducer can be matched with servo motor use, but these three reducer and have different characteristics.
 
For example, if you use a worm gear reducer, it is characterized by low cost, self-locking, low transmission efficiency and high noise.
 
If you use the planetary reducer, then one of its characteristics is high precision, transmission efficiency is much higher than the worm gear worm reducer, low noise, but the price is relatively expensive.

Then the hard tooth surface reducer, servo motor use hard tooth surface reducer is used in most cases because of the use of large equipment.
 
The hard tooth surface based on the manufacturing cost is relatively high, so the servo motor selection of hard tooth surface reducer must be careful about the accuracy of parameters.
 
Each type of servo motor reducer has its own characteristics, xiaobian here to remind you that no matter which type of servo motor reducer should pay attention to its daily use steps, such as the sudden failure of the servo motor reducer, how to solve it? This article will also explain the emergent fault solution.
 
The sudden failure of servo motor reducer refers to the failure with rapid development speed and mutability. It is characterized by sudden occurrence, no obvious and long-term development process and its accompanying symptoms, which is difficult to be predicted by condition monitoring, and the development process of the fault cannot be described or reflected with certain rules. Therefore, after a fault occurs, it is often easy to find the fault location, but the cause of the fault is not clear, and the fault can be judged only after analysis.
 
For servo motor reducer failure analysis of the commonly used method is, first to find out the main characteristics of the malfunction, various marks, especially in the development process of fault by the stress of the trace analysis of damage parts again, find out the causes of abnormal force, or contact related parts by fault feature analysis, the structural characteristics of Can achieve the purpose of understanding the root cause of the fault.
