<p>An electric motor having a stationary shaft carrying two spaced-apart bearings rotatably supporting a rotor. The shaft has an axial bore communicating with a radial slot in the shaft. An elongated locking member extends from the bore, through the slot, and into operative engagement with one of the bearings. A plug within the bore holds the locking member in place. A collar surrounds the shaft in the region of the slot, the locking member fixing one end of the collar against said one of the bearings. A compression spring surrounding the shaft presses against both the collar and the other of the bearings. The bore merges with the slot along an inclined surface which guides one end of the elongated locking member through the slot as the locking member is advanced along the bore during assembly.</p> |
