摘要

Apparatus for determining a service life for the determination of the service life of a bearing, the a axis of rotation of a machine, the apparatus for determining a service life of the bearing comprises:a storage unit, in the data are stored for a coefficient, which corresponds to a rotational speed of the axis of rotation, or a mathematical formula for calculating the coefficients from the rotational speed of the axis of rotation,a rotation speed - detection unit for detecting the rotational speed of the axis of rotation in a predetermined time interval,an amount of rotation - calculating unit for calculating an amount of rotation of the rotation axis, on the basis of the detected rotational speed and of the time interval,a unit for calculating a corrected amount of rotation for obtaining of the coefficients, the detection unit by the rotational velocity - detected speed of rotation corresponds to the axis of rotation, on the basis of the data stored in the memory unit or calculation formula, and for calculating a corrected amount of rotation for the service life determination by multiplying the by the amount of rotation - calculating unit calculated amount of rotation with the obtained coefficients,an integration unit for the corrected amount of rotation for integrating the calculated corrected amount of rotation, so that an integrated corrected amount of rotation is obtained, anda determining unit for determining that the service life of the bearing has elapsed, when a predetermined value by the integrated corrected amount of rotation is exceeded.
