A wiper mounted for rotation with the shaft of an apparatus such as an electric motor for preventing wicking by lint collecting on the portion of the housing surrounding the shaft opening thereof. The wiper, in the illustrated embodiment, is carried on the lubricant slinger mounted to the shaft and extending outwardly through the housing opening. The slinger, in the illustrated embodiment, is pressfitted to the shaft so as to permit the wiper to be accurately juxtaposed to the outer surface of the housing defining the shaft opening. In the illustrated embodiment, the wiper is formed integrally with the slinger. The wiper is preferably resiliently carried by the slinger so as to accommodate axial displacement of the motor shaft tending to bring the wiper into engagement with the housing portion defining the shaft opening.
In a rotary apparatus having a housing defining an end cap assembly provided with an opening on which assembly lint may be deposited, a shaft rotatively disposed in said housing and having a portion extending outwardly through said housing opening, and fluid lubricant on said shaft in said housing, an improved oil slinging structure comprising:
In an electric motor for use in an atmosphere wherein lint may be present and having a housing defining a portion provided with an opening on which portion lint may be deposited, an armature shaft rotatively journaled in a bearing in said housing and having a portion extending outwardly through said opening, and lubricating means in said housing for providing lubricant to said bearing, and lubricating means defining a lubricant reservoir in said housing, improved oil slinging structure comprising:
