Method and system for determining shifts in position

A method for determining shifts in position in at least two different spatial directions between a first bearing ring and a second bearing ring of a roller bearing, with the first bearing ring being fixed and the second bearing ring being rotatable relative to the fixed bearing ring about a longitudinal axis, and the roller bearing having at least two contactlessly measuring sensors, which are arranged spaced apart in the at least two different spatial directions from at least two standards fixedly connected to the second bearing ring, wherein sensor surfaces of the at least two sensors are opposite to the at least two standards in the respective spatial direction and register them, wherein:

• the at least two sensors scan the at least two standards and generate output signals in interaction with the at least two standards, using which in combination an absolute position of the second bearing ring is determined, which is connected to a rotational movement, and
• wherein furthermore by means of the output signals of the at least two sensors, values are determined which characterize the distance between the respective sensor and the corresponding standard of the second bearing ring in the associated spatial direction, which are corrected as a function of the ascertained absolute position of the second bearing ring, and from which the shift in position of the second bearing ring relative to the first bearing ring in the respective spatial direction is determined.
