ABSTRACT:
A scraper which has a bowl provided with an upright auger has a bottom bearing assembly on the bowl floor which supports the auger. The bearing assembly has a fixed lower housing with a stepped cavity containing bearings, and an upper housing rotatably carried in the bearings that has a through bore affording a lubricant chamber. The lower and upper housings have confronting external flanges between which is a metal-to-metal lubricant seal having elastomeric rings that must be compressed to make the seal effective. The bearing assembly includes surface engaging preload means in the through bore to depress the upper housing and thus compress the elastomeric rings, after which a cover plate is fastened on the top of the upper housing member and the lower end of the auger shaft is seated on a mating square stub on the cover plate. The weight of the auger further depresses the upper housing to disengage the surfaces of the preload means.
