Embodiment Construction

[0024] In this figure, in the left half of the figure, it is first visible how grease 2 is produced from the two grease components 3 and 4 . The illustration is simplified here and is not illustrated in that the grease 2 consists of only two components, a thickener or soap 3 and a base oil 4 . Mainly, the two components 3 and 4 are colored differently. The first fat component 3 is provided with a yellow pigment, while the second fat component 4 has a blue pigment.

[0025] The mixed components 3, 4 thus give a grease which (as a mixture of blue and yellow particles) is green in color.

[0026] This grease 2 (as shown in the right half of the figure) enters the rolling bearing 1 for the lubrication of the rolling bearing.

[0027] The rolling bearing 1 is provided with a color sensor 5 which is connected (by wire or wirelessly) to an evaluation unit 6 . The color sensor 5 measures the wavelength of light reflected from the grease, from which the color is derived.

Abstract

A method for operating a rolling-element bearing includes manufacturing a lubricating grease by mixing a first pigment having a first color with a first grease component to form a first colored grease component, mixing a second pigment having a second color different than the first color with a second grease component to form a second colored grease component, and mixing the first and second colored grease components to form a grease having a grease color. The method also includes lubricating the rolling element bearing with the grease, operating the bearing, measuring the color of the grease and providing a signal when the grease color becomes a predetermined grease color.

Description

technical field [0001] The invention relates to a method for running a bearing, in particular a rolling bearing, in which grease is introduced into the bearing. Background technique [0002] For bearings, especially in the case of rolling bearings, the state of the grease lubricant is of particular interest for the reliable functioning of the bearing or of the unit inserted into the bearing. [0003] Reliable information about the condition of the grease lubricant or about the duration of the service life allows an optimal configuration of the maintenance intervals of the system. As a result, on the one hand, short relubrication intervals are avoided, since these lead to higher costs. On the other hand, excessively long intervals are avoided, since they expose a higher risk of failure. [0004] In order to determine the state of the lubricant, it has been done so far to calculate or estimate the life of the grease on the basis of empirical knowledge. As an alternative, a ...
