Patent number: 6279734Abstract: A chain drum arrangement for a scraper-chain conveyor has a chain drum, which is connected at its end regions to two mutually aligned chain drum shafts mounted rotatably in a machine frame and, when uncoupled, can be removed from its fitted position transversely to its longitudinal axis from the machine frame. The chain drum shafts have terminal shaft journals projecting inwardly from side wall sections of the machine frame whereas the chain drum is provided, at its end regions, with substantially radially extending pockets with which it can be plugged onto the shaft journals and locked non-rotatably thereto The shaft journals are peripherally flattened to engage positively in the pockets and have external regions which act as locking claws fitting into undercut regions of the pockets when the drum is partly rotated around the journals. Closure members with screwed-on releasable locking plates serve to lock the drum on the journals.Type: GrantFiled: September 21, 1999Date of Patent: August 28, 2001Assignee: DBT Deutsche Bergbau-Technik GmbHInventors: Hans Meya, Gerhard Merten
