Abstract

340,450. Securing rotors on shafts. NAPIER & SON, Ltd., D., THOMAS, J. M., and HARLEY, H. G., 211, Acton Vale, Acton, London. March 7, 1930, No. 7505. [Class 80 (ii).] The rotor of a machine, such for instance as the impeller A of a centrifugal compresser, has externally splined sleeve-like extensions B, C, with bevelled ends B<1>, C<1>. The extension B fits into the internally grooved annular portion E<1> of the pinion E which abuts against the collar D<1> fixed on the shaft D. The extension C fits into an annular member G, and the members E<1>, G, have inclined surfaces, so that rotation of the nut H will cause the rotor A and the members E<1>, G to be wedged together on the shaft. The member G has curved fins G<2> which register with the vanes A<1> of the impeller. Grooves F<1>, E<3> are formed on the rotor casing and the member E<1> to prevent lubricant from creeping between the engaging surfaces. Finer grooves E<4> may also be employed with the same object.
