  • a rolling bearing is proposed, which has the Wälz stresses hofig and at least one rolling element. In this way, a high efficiency can be achieved.
  • the rolling bearing can in particular also be installed in transport equipment in mining or storage facilities of ships or in particular in large gearboxes.

  • the WälzSystemkorfigwand 16 is flat and is partially formed by a Sens mecanicselement 30, which is formed as a metal plate, which is formed of copper.
  • the rolling element 14 is circular-cylindrical, wherein it has a circular cylindrical recess 34 on its end face 18.
  • the sensors 20, 22, 24, 26 of the sensor unit 10 are arranged, which are arranged on the end face 18 of the rolling body.
  • the sensors 20, 22, 24, 26 are designed as distance sensors.

  • the sensor unit 10 detects the maximum skew angle 12, which the rolling body 14 in the operating state with the adjacent Wälzöfigwand 16, which is located directly opposite the end face 18, forms.
  • the maximum skew angle 12 is an acute angle and is formed by a first straight line 36 and a second straight line.
  • the first straight line 36 intersects the axis of symmetry 40 of the rolling body 14, which is circular-cylindrical up to the recess 34, at right angles. Further, the straight line 36 passes through that point 42 of the rolling element 14, which has the smallest distance from the WälzConsequentlykarfigwand 16.

  • the transmitting unit sends the distances by radio to an evaluation unit 46 of the wind turbine ( Figure 1).
  • the evaluation unit 46 has a transceiver unit, a computing unit, a memory unit and an operating program and calculates the maximum skew angle 12 from the distances.
  • the transceiver unit transmits the evaluation unit 46 a warning signal to a person who is responsible for a maintenance of the wind turbine.
  • the person can immediately carry out a maintenance, which leads to the fact that during operation, the maximum skew angle 12 is smaller again.

  • a sensor which is designed as a gyroscope, or two acceleration sensors, which measure accelerations along two mutually perpendicular axes to use would be arranged in the rolling element. With the gyroscope or the acceleration sensors, respectively, the position of the center of gravity of the rolling element can be detected, with which the position of the rolling element cage 28 can be concluded to a good approximation. With further Sens mecanicschal the gyroscope and the acceleration sensors then the maximum skew angle 12 can be calculated.
  • the invention can be applied analogously to rolling bearings with differently shaped rolling elements.
  • FIG. 4 shows an alternative embodiment. Substantially identical components, features and functions are basically numbered by the same reference numerals. However, in order to distinguish the exemplary embodiments, the letters "a" are added to the letter of reference in the exemplary embodiments in Figure 4.
