Definitions
- An electric motor armature shaft 13 is journaled within suitable bearing surfaces such as shown at 14 and 1S of the bearing assembly projection 11 on the back side of the bean'ng support member l0.
- a centrifugal impeller shaft 16 is journaled in suitable bearing surfaces 17, 18, and 19 of the bearing assembly support projection l2 on the front side of the bearing support member 10.
- a centrifugal gas compressor impeller 20 is secured to the shaft 16 for rotation therewith and a pinion gear 2l on the shaft 16 is geared to the bull gear 22 to rotatably interconnect the electric motor armature shaft 13 and the centrifugal impeller shaft I6.
