Abstract:
1. A method for determining operating parameters of a rotating roller bearing, comprising the steps of: fixing a sensor arrangement to the roller bearing; and generating a sinusoidal signal with the sensor depending on rotational position of the roller bearing, which is sampled at sampling points k, k+1, k+2, . . . , as a result of which samples, x*(k), x*(k+1), x*(k+2), . . . , are determined, where k is an integral as a run variable for elapsed time, wherein for determining rotational speed, of rotational direction, of radial force and/or of axial force, the signal at an amplitude of 0μV parallel to an envelope of the signal and is constructed by means of estimation, and the operating parameters are determined on this basis, and/or for determining the operating parameters of structural sound events, the samples are filtered in a high-pass filter for obtaining filter samples, v(k), v(k+1), v(k+2), . . . , and occurring structural sound is determined by means of estimation of a statistical moment at least of a second order, E{V
