“…Results show the importance of internal bearing contact angle variation on the high vibration modes. Alfares and Elsharkawy [11] showed the effects of axial preloading of angular contact ball bearings on the dynamics of a spindle. In a high-speed spindle the bearing axial preload is kept essentially constant during thermally generated changes to spindle dimensions by spring or hydraulic arrangements.…”

“…A correctly determined preload can have a positive influence on the distribution of loading of rolling parts in the bearings and thus on their durability [6]. For example, higher accuracy of guidance and higher stiffness assured by preloaded bearings of a pinion and bearings of a differential mechanism means that the co-face of the teeth will be more accurate, the value of contact will be more stable, and dynamic forces will be minimized [3]. As a result, the work will be less noisy, and the teeth in the bearing will be in a good condition for a longer time.…”

Optimum values of preload can be achieved in well-tried constructions and then applied in similar structures. For new structures, it is recommended to calculate the preload force and to test the correctness of calculation by means of experiments. In practice it may be necessary to introduce corrections, because not all real work parameters can be precisely known. Credibility of calculations depends, first of all, on the consistence between the assumptions concerning temperature conditions during work and elastic deformations of cooperating elements -first of all of a holder -and the real work conditions. The aim of the study is to determine how preload influences the work of a system of angular ball bearings, in relation to durability of bearing, moment of friction and rigidity of the bearing.

“…Initial preload of rolling bearings is widely applied to obtain high stiffness of machine tool spindles, restrain vibration and enhance rotational accuracy [1][2][3]. Proper preload of the angular ball bearing is important to the speed, rigidity, accuracy and life of the spindle.…”
