Abstract
An apparatus (10) for producing an orbital movement in a plane (20) is disclosed. The apparatus (10) comprises a lower shaft (40) and an upper shaft (30), being parallelly and eccentrically attached to one another, and a platform (50) mounted on the upper shaft (30). A ring gear (60) is attached to the platform (50) and coaxially rotatable about the upper shaft (30). A gear wheel (80) is coaxially rotatably mounted on the lower shaft (40) and engages with the ring gear (60).
Claims6
An apparatus for producing an orbital movement in a plane, the apparatus comprising:
- a lower shaft and an upper shaft being parallelly and eccentrically attached to one another;
- a platform rotatably mounted on the upper shaft;
- a ring gear attached to the platform and coaxially rotatable about the upper shaft, the ring gear comprising a plurality of interior teeth on a radially inward circumferential surface;
- a gear wheel, having a plurality of exterior teeth on a peripheral circumferential surface, being coaxially rotatably mounted on the lower shaft, wherein the gear wheel is so placed within the ring gear that at least some of the plurality of interior teeth engage with at least some of the plurality of exterior teeth;
- a first transmission device for driving the lower shaft;
- a first motor operatively connected to the first transmission device;
- a second transmission device for driving the gear wheel;
- and
- a second motor operatively connected to the second transmission device.
