Abstract

PURPOSE:To eliminate the creep deformation, etc. and prevent unbalanced oscillations by supporting stationary shafts provided at both ends of an impeller for oscillation-proof construction by use of bearings and oscillation-proof gums and connect them to a shaft on a motor side with a flexible joint. CONSTITUTION:A stationary shaft 4 on the left end is supported by a main body (not shown in the figure) with a bearing 9 and an oscillation-proof gum 10 for oscillation-proof construction, and the middle of a stationry shaft 15 on the right end is also supported by the main body with a bearing 16 and an oscillation- proof gum 17 for oscillation-proof construction. In addition, the tip of the shaft 15 on the right end and the tip of a shaft 13 of a motor 12 fitted to the main body not shown in the figure through an oscillation-proof gum 11 are connected together through a flexible joint 18. Thereby, the eccentricity between an impeller 2 and the motor 12 can be absorbed by the flexible joint 18, and unbalanced oscillations can be eliminated because the impeller 2 itself is supported by the main body for oscillation-proof construction by use of the bearings 9, 16 and the oscillation-proof gums 10, 17.
