| 摘要 |
The invention is drive mechanism for transmitting rotating motion, comprising a drive mechanism housing (15) and a first shaft (10) rotatably connected to the drive mechanism housing (15), an eccentric shaft section (14, 18) being parallel with the first shaft (10) and being offset with respect to first shaft (10) by an eccentricity parameter value, a wobbling disc (25, 27) being rotatably connected to the eccentric shaft section (14, 18), and a wobbling gear-wheel (24, 26) connected by means of a fixed or a releasable connection to the wobbling disc (25, 27) and having an axis parallel with the first shaft (10). The drive mechanism according to invention further comprises a transmitting gear-wheel (22) having an axis of rotation arranged parallel with the axis of the wobbling gear-wheel (24, 26) at a distance therefrom determined by the eccentricity parameter value, being connected to the drive mechanism housing (15) as being rotatable around its axis of rotation, having a first toothing (28) with a teeth number different from the teeth number of the wobbling gear-wheel (24, 26), and connected to the wobbling gearwheel (24, 26) with its first toothing (28), and a guiding connection establishing, upon motion of the first shaft (10), wobbling motion of the wobbling disc (25, 27) together with the connection between the wobbling gear-wheel (24, 26) and the transmitting gear-wheel (22), and having an axis being offset with respect to the axis of the eccentric shaft section (14, 18). |
