Summary of methods for gearbox vibration analysis and diagnosis
There are three specific analytical and diagnostic methods to detect vibration faults in gearboxes. One，Time domain averaging method The principle is to eliminate noise interference in the detection signal The main points of this method applied to fault analysis are: ① there should be two detection signals, one is the vibration signal, and the other is the time scale signal of the rotation of the rotor shaft; ② smooth filtering; ③ if you need to monitor each gear in the transmission chain, it...
Gearboxes are a critical component of many mechanical devices, and their maintenance and upkeep are essential to ensure proper operation and extended service life of the equipment. Here are some key points about gearbox maintenance: 1. Lubricant management Regularly check the level and quality of the lubricant to ensure it is clean and of the proper viscosity.

What is a gearbox and what does it do?
Gearbox is an important mechanical transmission device that is widely used in several fields. The following are some of the main applications of gearboxes: 1. Wind power generation: In wind turbines, gearboxes are used to transfer the power generated by the wind turbine under the action of the wind to the generator and to bring it up to the corresponding rotational speed. Since the speed of the wind turbine is usually low, the gearbox achieves this through a speed-increasing action, hence the...
