The invention relates to a method for determining a load zone (A) in a roller bearing (1), wherein the roller bearing (1) has at least two bearing rings (2, 3) and roller elements (4) between the bearing rings (2, 3). To allow a non-invasive and precise determination of the load zone in the bearing in an easy manner, the invention is characterized in that the method comprises the steps: a) emitting radially directed ultrasonic signals (S) from a radial inner or outer surface (5) of one of the bearing rings (2, 3) into the roller bearing (1) by means of at least two ultrasonic sound generators (6 ', 6", 6 ' ",...) at at least two distanced locations (11', 11 ", 11 ",...); b) sensing the ultrasonic signals (S') at the radial inner or outer surface (5) which are reflected at the transition zone (7) between the bearing ring (2, 3) and the roller elements (4) by means of at least two receivers (8); c) determining and forwarding the contact status between the bearing ring (2) having the ultrasonic sound generators (6', 6", 6"', ) and the receivers (8', 8", 8"',...) and the roller element (4) at each of the distanced locations (11', 11 ", 11",...) by evaluating the reflected ultrasonic signals (S') received by the receivers (8', 8", 8"',...). Furthermore, the invention relates to a device for determining the load zone in the roller bearing. |
