Abstract
The invention relates to an airtight rotating driving device with eccentricity, especially for volumetric pump.
The device comprises a bent shaft (1) presenting an input axis (5) and an output axis (10) parallel and off centered in such a way as to carry out an orbital circular movement, and an airtight and non-rotatable sleeve (14) surrounding the shaft and comprising two metallic bellows (19, 20) linked by a guiding ring (21) mounted longitudinally in a sliding relation on the sloped intermediate section (17) of the shaft.
Utilisation for converting a rotating movement into an orbital circular movement with an absolute airtightness.
