The use, maintenance and installation rules of the reducer are ignored by the majority of users, resulting in the reduction of the service life of the reducer. Most users use, install and maintain the reducer based on previous experience and independent research methods, and there is no technology to speak of. When the reducer manufacturer develops and manufactures the reducer, it has a set of instructions for use, installation and maintenance, which inform and remind users how to use, install and maintain the reducer.
The most common faults of single-stage worm gear reducer are gear damage, bearing failure and gear failure, which shows the position and importance of gear problems in the reducer. Generally, the gear reducer needs to be shut down for maintenance, which is relatively troublesome. Therefore, the research on maintenance and fault diagnosis of gear reducer without disassembly and shutdown can have extremely important technical and economic effects.
When the transmission shaft, gear and bearing of the reducer are working, no matter whether there is any fault, they will generate vibration. If a fault occurs, the amplitude of the vibration produced will increase, and the energy distribution of the vibration signal will change. Therefore, it is one of the more effective methods to often use the vibration analysis method to diagnose the fault of gear reducer. Tooth surface wear, pitting, shaft bending and tooth breakage are typical faults, which can be analyzed from the vibration characteristics of gear reducer.
