Abstract
The invention relates to a multipart drive shaft of a chain drive for chain scraping conveyors for heavy-duty sprags in coal mining, consisting of a main shaft with unilateral or bilateral internal gearing for receiving externally geared stub shafts for the gear connection, and a chain sprocket fastened to the main shaft for interaction with the conveyor chain band. In this invention, the chain sprocket fastened to the main shaft is constructed in multiple parts by radially running segments, and is shrink-fitted in several or all individual parts to the main shaft. In accordance with the invention, a radial division into two shrink-fitted casings and a chain drum is especially appropriate and economical.
