THE SELECTION OF PRELOAD IN ANGULAR CONTACT BALL BEARINGS ACCORDING TO THE DURABILITY CRITERION
Journal Title: Tribologia - Year 2018, Vol 277, Issue 1
Abstract
The regulation of the preload of angular contact ball bearings is mentioned in specialist literature, but only as a practical activity carried out based on experience, still without selection methodology. At present, there exists no widely accessible method of this load selection. Neither the literature on the subject nor catalogues of bearings producers give recommendations for the selection of this parameter, which is most often perceived intuitively. Still, it is known that its wrong selection can have a catastrophic influence on the durability of bearings. In consequence, there exists a problem of the accurate choice of preload (i.e. of such a preload that the durability of bearings will not be significantly decreased). The aim of the study is to determine the maximum preload in angular contact ball bearings by the criterion of durability, taking into account shaft flexibility and the flexibility of bearings. In order to determine a general influence of preload on fatigue life of bearings, numerous calculations were made for different locations of the plane of load.<br/><br/>
