Abstract

The accuracy of guiding a spindle is greatly influenced by the thermal load of the bearing. Increased thermal load implies deformation of the bearing parts which is directly reflected in the work quality of the machine system. For this reason, the aim of this paper is to analyse the influence of the material and the geometry of the housing on the temperature field of the threaded spindle bearing assembly, which was realised by "radially mounting" of axial angular contact ball bearing ZKLN. This paper represents a new approach for thermal analysis of the special bearings, type ZKLN which are not involved in the relevant standards for the determination of the reference speed. At the same time the value of this paper finds itself in finding of the guideline at engineering practice which is very important at early design phase of the systems with threaded spindle. The analysis was carried out using experimental and numerical methods. Combination of the mentioned methods gave result which was used to define appropriate guideline regarding influence of housing material and geometry on thermal stability of the ZKLN bearing.
