SUBMERSIBLE PUMP AND BEARING ARRANGEMENT

摘要

A submersible pump includes a bearing arrangement and a rotor shaft. The bearing arrangement includes a bearing cover, a bearing flange, and one or more bearing elements, each bearing element having an inner bearing ring, an outer bearing ring and a roller element. The rotor shaft is rotatably supported in the one or more bearing element about an axis of rotation extending in a longitudinal axial direction so that the inner bearing ring is configured to rotate along with the rotor shaft in an operating state. The bearing element is arranged at the bearing flange such that the bearing cover tensions each outer bearing ring in a longitudinal axial direction and such that a peripheral gap having a predefined axial width is formed in a radial direction between the outer bearing ring and the bearing cover and between the outer bearing ring and the bearing flange.
