Abstract: The article notes that as a result of the processes of mechanical processing, heat treatment and assembly of parts included in the machine spindle assembly, in the latter occur deviations in the location of their responsible base surfaces . Are given the obtained analytical dependences, which make it possible to determine the modulus and phase of the angles of mutual misalignment of the rolling surfaces of the outer and inner rings of the bearings of each of the supports. Calculations based on the obtained dependences showed that the axis of rotation is curved, and the geometric axis of the spindle describes a closed shape around the axis of rotation. Based on theoretical studies and computer modeling of the spindle assembly, conclusions are drawn about the influence of the misalignment of the outer rings of bearings and the deviation from the alignment of the inner rings of bearings on the runout of the spindle axis, the displacement of the center of rotation and the runout of the working end of the spindle.
Key words: spindle assembly, spindle rotation, skew angles, deviation from alignment, modeling, changing the position of the center of rotation.
