ABSTRACT:
A bearing and seal assembly for use in an electric motor rotor or stator bore about a central shaft. The bearing and seal assembly comprises a drawn aluminum sleeve dipsosed in and secured to the wall of the bore and having opposite end portions projecting beyond the bore wall. A sleeve bearing is press fit in the sleeve with the sleeve press fit or adhesively secured in the bore. An annular seal is press fit in one projecting end portion of the sleeve and is thus held in precise coaxial relationship with the bearing. The opposite projecting end portion of the sleeve provides a seat for an O-ring at a diametrically enlarged portion thereof. A cap in snap engagement with the rotor or stator, or alternatively with the sleeve, engages the O-ring and closes a lubricant chamber surrounding the bearing and within the sleeve. The assembly method includes press fitting of the bearing and seal in the sleeve with the elements mounted on an assembly pin for precise concentricity or coaxial relationship. Alternatively, the sleeve may be press fit in the rotor or stator bore or adhesively secured therein.
