Abstract
A drive unit for oscillatingly driven mowing sickles has a first transmission unit {} with a first housing () defining a first axis (). A rotor () is rotationally supported in the first housing () around the first axis (). A first internal gear wheel () is fixed in the first housing () and provided with internal teeth. A toothed pinion () is rotationally supported in the rotor () around a second axis (). The second axis () is radially off-set to the first axis (). The toothed pinion () forms the output element of the drive unit and meshes with the first internal gear wheel (). A second transmission unit () has an output () non-rotationally connected to the rotor () of the first transmission unit (). The second transmission unit () is formed as a step-down gear. A motor (), with an output shaft (), rotationally drives the second transmission unit (). The rotational speed Nis reduced by the second transmission unit (), formed as a step-down gear, to the rotational driving speed Nof the first transmission unit ().
