High-frequency Vibration Analysis of Planetary Reduction Gearmotor

In this article the analysis of signals from vibration sensors in a high-frequency range is presented, and also conclusions about advantages of high-frequency vibration analysis at vibration diagnostics of planetary reduction gearmotors are done. 1. INTRODUCTION Due to wide kinematics possibilities, economy, reliability, small size, low noise level, planetary reduction gearmotors are found wide application in machine-building. Also planetary reduction gearmotors have transmission of large power possibility at small sizes and small loading on gear cogs and on supports. The all above enumerated advantages will be in use only in case, when planetary reduction gearmotors work smoothly. For this purpose it is necessary to carry out the vibration monitoring and diagnostics of these gearmotors timely. The special attention must be attending the analysis of high-frequency vibration, because only at the signal analysis in a high-frequency range it is possible to find out the incipient defects.
