Abstract

This invention relates to a chain drum arrangement for a central or double central scraper chain conveyor, comprising a divided chain wheel, the shell-type chain wheel segments of which are attached, locked in rotation and detachably, via an axial splined portion to the shaft, wherein the chain wheel is secured in its installed position on the shaft by means of locking rings disposed on both sides and at least one of these two locking rings consists of a divided locking ring which can be taken off radially from the shaft in order to remove the divided chain wheel from the shaft. According to the invention, the divided locking ring is disposed as an intermediate ring between the divided chain wheel and a hollow journal which receives the respective shaft bearing and which projects axially from the respective side cheek of the machine frame into the interior space thereof, which results in a narrow mode of construction of the divided locking ring.
