[0002] Gearbox is an important part of mechanical transmission equipment, and its operating status is directly related to the safety, reliability, and maintainability of the mechanical transmission system and the operation of the whole machine; with the automation, systematization, complexity and The degree of precision is getting higher and higher, and the gearbox box is closed, the internal temperature is high, the speed is high, there is lubricating oil, there is oil gas, there is variable speed, variable load, and the installation space is small, so it is urgent to develop a gearbox that can meet the above special mechanical environments. The state monitoring system of mechanical transmission equipment under the existing technical transmission state monitoring system is expensive, large in size, and difficult to supply power. By installing the sensor outside the mechanical transmission equipment box, it is far away from gears, bearings and other high-failure-prone equipment. , the sensor can only be installed in a fixed position such as a gear box far away from the fault location, where it will not rotate, resulting in many sources of signals sensed by the sensor, a wide sensing area, and at the same time affected by the transmission path, structural quality, friction and Due to the influence of mutual coupling between structures, there are shortcomings such as less original signal components, large noise interference, and poor environmental adaptability.
