SELF-WEIGHTED SHAFT WITH CONTROLLED FLEXURE Russian patent published in 1997 - IPC

FIELD: mechanical engineering, paper-making industry. SUBSTANCE: shaft has at least one bearing shoe installed at carrier stationary axle for shaft jacket flexure level control with respect to press-contact plane. At every end of shaft there are two bearing guide-members in opposite directions for shaft jacket forcing for positioning stabilizing with respect to stationary axle. One at least bearing guide-member at any end of shaft has dummy piston which working had can replace in radial direction outward bearing mounted at stationary axle. Guide-members can move reciprocally on planes parallel to press-contact plane which includes longitudinal axis of shaft, so guide-members provide opposite directed and equal magnitude stabilizing forces of normal action with respect to plane of press-contact. Bearing guide-members have axis-directed bulbs stopped by thrust rings of end-faces of shaft jacket made for jacket retaining in longitudinal direction with respect to carrier stationary axle during operation. EFFECT: enhanced operation. 8 cl, 10 dwg
