Abstract The endbell of a motor is of stamped sheet metal including a cup-shaped central portion surrounded by a flange-like outer portion which is secured to the stator and which supports a device for providing an oil passageway to a centrally located bearing. The cup-shaped endbell portion is part of the bearing housing that also includes a second cup-shaped member disposed within the first cup-shaped portion in opposite facing relation. The two cup-shaped elements have shaft receiving apertures and contain a bearing and oil retaining wicking material. One of the cup-shaped elements has an additional aperture off the shaft axis. The oiler device is a unitary member of molded plastic material; it is snap fit, without fasteners, in an aperture in the flange portion of the endbell and has an extremity in the aperture of one of the cup-shaped elements. The outer extremity of the oiler device is proximate the radial extremity of the endbell.
A dynamoelectric machine comprising, in combination: an enclosure including an endbell of sheet metal having a cup-shaped central portion surrounded by a flange-like portion, said cupshaped central portion forming part of a housing for containing a bearing; said bearing housing also comprising a separate cupshaped member with a rim secured within said cup-shaped central portion, said cup-shaped member having a shaft aperture in alignment with a shaft aperture of said cup-shaped central portion, said housing also having an additional aperture in one of said cup-shaped elements; an oiler device of a unitary member having a tubular passageway through a body disposed radially against a surface of said flange-like portion and retained thereon by a projection locked within an aperture of said flangelike portion, said body including a stem-like portion with an extremity within said additional aperture.
