Gearbox Vibration Sensor and AE Sensors for Monitoring a Machine’s HealthPosted by eliteinternet on February 10th, 2020 Primarily, the gearbox vibration sensor comes built-in the product to prevent grime and grease and to correct any issues with gear meshes. Importance of gearbox systems: Before heading towards the gearbox vibration sensor, it is vital to learn the importance of gearbox systems first. These systems will play a key role in multiple machines like power plants and production machines and functions in multiple industrial applications.
The industrial community needs reliable and effective sensing tools for monitoring the machine’s health condition and capturing structural defects within initial stages. So, some of the Acoustic Emission sensors and accelerometers are widely used in many applications to monitor the machines used. Acoustic Emission and Vibration Characteristics: Some research operates with machine vibration and acoustic emission with advanced signal techniques that have already been examined for monitoring and predicting the present health of the rotating machine. The interest related to applications through acoustic emission for condition monitoring systems has grown over time. Even though the field of vibrating monitoring has dominated several decades to cover industrial applications, acoustic emission technology offers attractive advantages when it comes to machine vibration. Acoustic emission will not have any specified direction and in some instances, one AE sensor is more than enough to complete the task. In contrast, the vibration monitoring tool will need data from a minimum of 3 sensors from 3 various axes to perform well. The position of these sensors is important for procuring major data relating to the condition of the machine. This sensor is chosen depending on the calculated gear mesh frequency and even some of the bearing defect frequencies. You can easily determine the gear mesh by multiplying the number of gear teeth by its rotational frequency. For example, any motor that comes with 1800 rpm and gear with 50 teeth might result in a frequency of 1500 Hz. The result then gets multiplied by a factor of around 3.25 for providing you with information on the maximum frequency that the sensor canmeasure, providing you with the best results. If the gear comes with an unknown number of teeth, the maximum sensor frequency will be assumed to be around 200 times rpm, as a rule of thumb.
