Abstract
An adjustable attachment for connection of a rotor to a shaft which provides precise axial positioning of the rotor with respect to a motor housing. The adjustment is effected by a screw mounting of the rotor on the shaft and spring discs placed in a compartment in the motor housing with a shaft spacer placed between the rotor and the discs. The adjustment feature is especially adapted for use in conjunction with sliding vane type vacuum pumps, compressors and air motors.
