Abstract

An electric power train includes an electric drive, an electric motor driven by the electric drive, and a meshing pair of a drive gear (G1) and a driven gear (G2). The drive gear (G1) is coupled to the electric motor and the driven gear (G2) is coupled to a mechanical load. The backlash of the meshing pair of the drive gear and the driven gear is measured and estimated based on a time (Δ) until a contact of teeth (22, 24) of the rotating drive gear (G1)and the driven gear (G2) during a startup of the electric motor. Wear of the meshing pair of the drive gear and the driven gear based on a change in the measured backlash over time during the operation of the electric power train.
