DRIVE SYSTEM FOR IMPELLER SHAFTS

摘要

A~drive system for impeller shafts includes a coupling that has a universal joint that is lubricated under all operating conditions. A housing is connected to the universal joint, which housing includes a hollow end portion adapted to receive the non- threaded end of an impeller shaft. A threaded stud projects from the end of the shaft and into the housing where the stud is secured by means of a nut. The nut is readily accessible to the user so that the axial position of the shaft can be adjusted without difficulty. The nut is releasably held within the housing so that the shaft and stud, with nut attached, can be quickly disconnected from the coupling. The invention also includes a modified "square driven" configuration for the ends of the shaft that is extremely strong and enables the shaft to be connected to the impeller and the coupling very easily.
