Abstract
The invention relates to a method and a computer programme for detecting the stationary state of a roller bearing, comprising z rolling bodies, where z is a whole number, preferably an even number, to which a sensor arrangement is fixed, delivering a sinusoidal signal, dependent on the rotational position of the bearing on the rotation of the roller bearing. Said sinusoidal signal is sampled, whereupon sampled values are determined. According to the invention, a first average value (MW) of the sampled values of a first time interval (J) is determined (S), whereupon the corresponding average value (MW, MW) of other time intervals (J, J) is determined (S). The roller bearing is considered stationary as long as A) the corresponding average value (MW, MW) of the other time intervals (J, J) does not differ (S) significantly from the first average value (MW) and/or B) the gradient between the first average value (MW) and the corresponding average value (MW, MW) of the other time intervals does not differ significantly from 0 (S). The invention further relates to a roller bearing, provided with an analytical device for carrying out the inventive method or the computer programme.
