Abstract
A friction roller conveyor includes friction rollers mounted within a housing. A housing cover has openings therein through which the friction rollers partially extend. The rollers are secured against axial shifting and are driven. The friction roller conveyor is made from easy to assemble and replace individual elements, and may be walked on and driven over without damage to the conveyor, the people or to the crossing vehicles. Repairs can be made without disassembling the entire conveyor construction.
Claims8
A friction roller conveyor comprising at least one housing, a removable cover for the housing having spaced apart openings therein, a plurality of friction rollers mounted in the housing partially extending through the openings in the cover, a pair of opposed U-shaped box sections spaced apart and generally parallel to one another with the housing connected to and extending therebetween, a drive shaft in the housing upon which the friction rollers are loosely mounted such that they are capable of axially moving along said drive shaft, bearings secured to the U-shaped box sections rotatably supporting the drive shaft, drive means disposed in at least one of the U-shaped box sections connected to drive the drive shaft, and, replacable guide elements not fixedly attached but releasably connected to the housing cover at the periphery of the openings therein for preventing axial movement of the friction rollers on the drive shaft.
