The present invention relates to a method for detecting play in bearings and control mechanisms of a runner or rotor with turnable blades. The invention is characterized in that a specific angular position during rotation of the rotor is detected, and that the angular position of the blade points during rotation of the rotor is detected for upwardly directed, and for downwardly directed load acting on the blade points, starting from the specific angular position of the rotor, wherein the difference in angular position for respective blade for upwardly directed and for downwardly directed load is used as a basis for the determination of the play in bearings and control mechanisms of the respective blade. The invention also relates to a device for carrying out of the method. |
