Regarding One Estimation of the Technical Condition of the Selective Headers

摘要

The paper presents an issue of estimation of the technical condition of the selective headers applying mathematical model of alteration of the actual condition of an object of diagnostics. The paper shows that a complex method is more relevant to the selective headers; the method is based on emission-and-spectrum analysis of lubricant oil for cutting gear, and analysis of mechanical vibration in cutting drive. As an example of degradation of the cutting gear in a header SM-130K as per alteration of mechanical impurities content in lubricant oil and vibration intensity on the cutting gear mounting group has been reviewed. It is shown that the developed forecast model, based on statistical analysis of the results of the lubricant oil and parameters of mechanical vibrations, allows with 95% confidence probability to predict a moment of the cutting gear breakdown and schedule a timely maintenance.
