CENTRIFUGAL DEVICE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; centrifugal plants with vertical shaft of working member. SUBSTANCE: proposed centrifugal device has housing, rotor with vertical shaft whose upper part is mounted in bearing unit, flexible supporting unit connecting the bearing unit with housing and drive. Flexible supporting unit of upper part of rotor shaft is ring-shaped in form; it is mounted coaxially relative to bearing unit and is provided with fixed base in form of flat rings. Fixed base is rigidly connected with housing and movable base is rigidly connected with bearing unit. Flexible supporting member made in form of rubber shock-absorber is located between bases. Movable base is located in upper part of supporting unit, flexible supporting member is fitted tightly relative to lateral surfaces of bearing unit and housing; rotor shaft is flexible. Proposed device ensures angular displacement of rotor excluding slippage of movable base in radial direction and reducing number of parts of flexible unit. EFFECT: enhanced efficiency and reliability. 2 cl, 1 dwg
