Bearing Units and Surface Micro-Geometry of Rolling Races in Textile Machinery

The paper dealt with surface micro-geometry and influence on generation of unwanted vibrations of bearing units in textile machinery. Any deviation of ideal shape of contact surface of shaft and inner bearing ring considerably influence the shape of bearing rolling race. The dimension and geometry accuracy of shaft is very important for intended lifetime, operating speed and mounting of bearing. Moreover, paper evaluates dependency of dimension and geometry shaft accuracy on bearing lifetime according to experimental measuring.
