Roller body for roller bearing

Abstract

A roller body for a roller bearing includes at least one cavity extending from an end face of the roller body, at least one retaining element is disposed in the cavity, and at least one sensor is disposed in the cavity, such as in or on the retaining element. The sensor is at least partially surrounded by an elastic material in a protective manner.

Description

technical field [0001] The invention relates to a rolling element for a rolling bearing. Background technique [0002] In the use of rolling bearings, the generally rotational movement between two bearing rings can be achieved by the rolling movement of the rolling bodies arranged between them. To accommodate relatively high loads, for example in wind power installations or in the automotive and heavy machinery industries, cylindrical roller bearings or tapered roller bearings are preferably used. In cylindrical roller bearings, the rolling elements have a cylindrical basic shape, in tapered roller bearings, the rolling elements have a conical basic shape. In particular large radial loads can be transmitted via cylindrical roller bearings, whereas tapered roller bearings can only additionally accommodate axial loads. [0003] During operation, rolling bearings are generally subjected to numerous ambient influences which are detrimental to the running and service life chara...

However, this results in greater material and cost expenditure

In addition, rolling bearings may be subject to regular inspections, which also means higher costs
