Abstract

Spindle is a core component of machine tool. Similarly, the bearings are the significant assembly of the spindle. Bearing preload optimization is beneficial to improve the dynamic characteristic of the spindle and the machine tool working accuracy. This paper presents the relationship between the bearing preload and bearing fatigue life, temperature rise, giving out a new method for bearing preload optimization.
