Rolling bearing assembly, apparatus and method for determining a used and / or remaining period of a grease service life

摘要

A rolling bearing arrangement comprising: a first and a second raceway element and rolling elements arranged between the two raceway elements such that the two raceway elements are rotatable relative to one another in the manner of a roller bearing, a space between the raceway elements in which the rolling elements roll, which comprises a lubricating grease, - at least one sensor element for detecting a temperature at a specific point of the rolling bearing, in particular in the space, and for detecting a speed of the rolling bearing and a unit which receives the detected temperature and speed, from the profiles the calculated temperature over time and from the speed over time via a calculated energy exerted on the fat, a used and / or remaining period of the fat life calculated.
