Electromechanical drive unit e.g. steering drive for rotary turntable of conveying vehicle, has conversion gearing coupled to electric motor provided by eccentric gearing

摘要

The electromechanical drive unit has an electric motor (1) coupled to a conversion gearing for rotation of a rotary element, the conversion gearing provided by an eccentric gearing (2) at least partially located within the axial length of the rotor (5) of the electric motor, with a planetary wheel shaft (7) supported in an eccentric bore (5a) of the rotor via 2 axially spaced needle bearings (8,9).
