Embodiment Construction

[0018] In the following description of the drawings showing the embodiments, the same reference numerals denote the same or similar components. Furthermore, generalized reference signs are used for components and objects that appear several times in the exemplary embodiments or figures, but are described in common with respect to one or more features. As long as the description does not expressly or implicitly express differently, parts or objects described with the same or general reference signs can be designed to be the same in individual, multiple or all features, such as their dimensions, but also when necessary can be designed differently.

[0019] Some embodiments relate to a bearing system or bearing arrangement for supporting mutually movable components. The bearing system has at least one bearing and a preload. The preload device varies the preload of the bearings based on the operating conditions of the bearing system.

[0020] For example, the rigidity, bearing ...

Abstract

A bearing system for supporting components that are movable relative to one another includes at least one bearing and a preload mechanism for changing a preload of the at least one bearing based on an operating state of the bearing system, where the preload mechanism includes, for example, a piezoelectric element, a Peltier element, an expansion material or a micromechanical element.

Description

technical field [0001] Embodiments of the invention relate to a solution for preloading a bearing and in particular a bearing system and a method for operating a bearing system. Background technique [0002] In bearing systems for supporting mutually movable components, it is necessary to adjust a positive or negative running bearing play in the bearing arrangement. In many fields of application a positive running bearing play may be desired, ie a small residual bearing play remains in the bearing during operation. [0003] However, in many cases, for example, in bearings of machine tool shafts, gear bearings in vehicle drives, bearing arrangements in small electric motors or bearing arrangements with oscillating movements, a negative running bearing play is desired, that is to say a desired preload , used to improve the rigidity of the bearing device or improve the running accuracy. [0004] In many applications, the selection of the preload of the provided bearing system...
