Abstract

174,350. Allis-Chalmers Manufacturing Co., (Assignees of Binder, H. P., and Humphrey, N. H.). Jan. 21, 1921, [Convention date]. Securing rotors on shafts.- Relates to means for securing the rotor of a centrifugal pump or hydraulic turbine to its shaft to permit of the rotor being removed or adjusted from outside the casing. In a centrifugal pump having a casing 2, 3 and the impeller 10 coated with a protective layer of rubber 6, 7, 11, the impeller is feathered. on keys 13 of the shaft 12 and is adjusted axially thereon by a flanged sleeve 14, which engages at one end a screw-thread 24 on the shaft 12, and can be locked in any desired position thereon by a set screw 18 engaging slots in the sleeve and shaft. The adjustment or removal of the impeller from the shaft is effected from outside the by a spanner engaging holes 19 in the sleeve 14. In a modification, the impeller is screwed on to the inner end of the sleeve 14, and engages two or more stepped cylindrical surfaces on the end of the shaft 12 to facilitate removal.
