Abstract: A method is provided for evaluating a maintenance requirement of a linear transmission device that is driven by a driving device. A control unit receives, from a sensing unit, a plurality of electric sensor signals that respectively correspond to multiple physical quantities of the linear transmission device or the driving device. The control unit calculates at least four correction factors based on the electric sensor signals, and calculates a service life of the linear transmission device based on the electric sensor signals and the at least four correction factors for scheduling maintenance of the linear transmission device.
