Device with at least one elastically deformable component, in particular a rubber-metal bearing and with a device for determining the beginning of a wear-related component remaining service life, as well as methods for determining the component remaining service life

摘要

The invention relates to a device having at least one elastically deformable component as a structural part and / or bearing part, which act in the course of operation of changing operating conditions, different deformation forces that lead to a component life limit component wear, and with a device for determining the component life and a wear-related component remaining service life. According to the invention, a time-repeating, respectively identical operating state is predetermined, to which a respective, periodically acting deformation force is assigned, by which the elastically deformable component material is periodically deformed, wherein by flexing an energy input with a measurable temperature increase compared to an ambient temperature and takes place the respective increase in temperature as characteristic variable in the course of a component service life increases in accordance with a decreasing component rigidity. Such a predetermined operating state is detected in each case by a measuring and evaluation unit and automatically started a measuring operation by a start signal, wherein measured with at least one component temperature sensor, the current temperature rise compared to the ambient temperature as a parameter for a current component stiffness and stored in a waveform and is compared.
