THE ANALYSIS OF THE DYNAMIC LOADING OF HIGH-SPEED SPINNING HEADSTOCK COMPONENTS

The article deals with the effective design of vibro-diagnostics of sources caused by self-excited vibrations of a high-speed spinning headstock bearing generated by residual unbalance, the quality of production and assembly of high-speed spinning headstock components. It also analyses the dynamic load from external vibration sources, primarily from the guide and pressure pulleys of the drive belt, as well as the effect of the Eigen frequencies of the Eigen modes of the test equipment. The article suggests the possibilities of analysing the dynamic load of high-speed headstock bearings using diagnostic sensors and it also indicates the calculation of the sound power level from the vibration velocity of the high-speed spinning headstock and/or another analysed component. The aim of this article is therefore to contribute to the reduction of energetic, dynamic (vibration and noise) and economic demands using operational condition monitoring in the production of textile yarn by improving the performance properties of high-speed bearings of spinning headstocks, which form an essential part of spinning technology.
