Abstract

1,228,678. Securing impellers on shafts. MITSUBISHI JUKOGYO K.K. 20 Aug., 1969 [20 Aug., 1968], No. 41622/69. Heading F2U. A centrifugal impeller 2 and an inlet vane assembly 4 are secured on tapered portions 1b, 1c of a drive shaft 1 by an end nut 7 with biasing springs 8, 9 between the members 4, 7 and 2, 4 respectively, the loading of spring 8 being greater than that of spring 9, preferably twice as great, so that under all conditions of operation the springs bias the members 2, 4 against the tapered shaft portions 1b, 1c. The torque loading is transmitted by keys 3, 5.
