ABSTRACT:
A frame assembly for a scraper-chain conveyor which is usable as a drive or reversing station. The assembly has bearing units, which are supported by spaced-apart side walls. A shaft carrying a chain wheel for engagement with the scraper-chain assembly of the conveyor is mounted for rotation between the bearing units. The chain wheel is constructed from separate parts and can be readily attached to or detached from the shaft without removing the latter. The bearing units have hollow projecting parts which accommodate bearings for the shaft which are protected by seals. These projecting parts smoothly merge with the exterior of the chain wheel. The shaft has hollow end portions provided with splines which can be coupled to a journal introduced into the associated end portion from the exterior of the associated bearing unit which also provides access to the bearings and seals. This journal can then be coupled to a drive means to effect rotation of the shaft.
