Abstract:
A bearing cartridge support for roll apparatus, such as roll screens, feeders, conveyors, and the like, having a frame and a plurality of parallel horizontally extending rolls journaled for driven rotation. The bearing supports include a vertical support carrying a bearing cartridge in the form of a hollow cylindrical housing having a pair of spaced apart bearings therein. Each support plate has lap tongues along its opposite vertical edges and vertically spaced apart fastening means engageable in longitudinal channels in the frame. The ship lapping facilitates maintenance of a seal while permitting variation in spacing between adjacent bearing cartridges. A short roll-supporting stub shaft is journaled for rotation in each bearing, these shafts being engageable by the ends of rolls to be supported within the frame. The stub shafts on one side of the apparatus are adapted to be driven within a closed case protected against entry of abrasive foreign materials. The use of stub shafts permits the easy removal and replacement of worn rolls.
