ABSTRACT:
A conveyor apparatus includes a drive unit with a drive sprocket assembly of an armored face conveyor having a central drive shaft for rotation within a lubricated bearing. A bearing housing encloses the bearing and includes an array of access ports circumferentially spaced around the perimeter. A split conveyor frame defines semicircular mounting rings for receiving the bearing housing and securely mounting the drive sprocket assembly. A lubricant channel is provided in the surface of one mounting ring, and the surface of the other mounting ring provides a lubricant seal. The lubricant channel aligns with the access ports of the bearing housing, and includes stopper plugs at each end to restrict the lubricant flow. A transfer tube having a lubricant fitting on a first end transversely extends across the conveyor assembly. A lubricant passage in the conveyor frame extends between the lubricant channel and a feed orifice of the transfer tube. Lubricant applied at the fitting is communicated through the transfer tube and lubricant passage to fill the lubricant channel. From the lubricant channel, lubricant is forced through the access ports of the bearing housing to effectively lubricate the internal bearing.
