ROLLING BEARING HAVING AN INTEGRATED GENERATOR AND METHOD FOR THE ENERGY MANAGEMENT OF A ROLLING BEARING OF SAID TYPE

摘要

The invention relates to a rolling bearing having a permanently excited first generator (09) which is arranged in the intermediate space between two bearing rings which are rotatable relative to one another, said first generator comprising a primary part and a secondary part and generating a first generator voltage when it operates, wherein the secondary part has permanent magnets (04) which are arranged with alternating polarity on the circumference of one of the bearing rings at least in sections. According to the invention, the rolling bearing comprises a second generator (21), wherein the first generator voltage serves for the supply of energy to a sensor arrangement and/or actuator arrangement integrated in the bearing, whereas the second generator outputs a voltage signal for position determination and rotational speed measurement. The invention also relates to a method for the energy management of a rolling bearing of said type.
