  • Mechanism for feedthrough of rotary motion to a sealed chamber
    Patent number: 4885947
    Abstract: A rotary motion feedthrough mechanism for a sealed chamber comprises a first driven shaft (56) with a through opening (66) and a second driven shaft (96) moveably inserted into the through opening of the first shaft. At its rear end the first driven shaft has a recess (102) which is eccentric and inclined with respect to the axis of rotation of both shafts. The recess rotatingly supports one end of a conical sleeve (110), the other end of which is rotatingly supported in an inclined opening of an external sleeve (68) which is connected to a rotary drive unit through a sprocket (76) installed on the outer surface of the external sleeve. The end of the second drive shaft opposite to the eccentric opening of the first shaft is connected to an independent rotary motion feedthrough mechanism which is capable of transmitting rotation into a sealed space. When the mechanism is sealingly connected, e.g.
