Abstract
A chain drive for a link chain of mining conveyors or mining extraction machines, in particular for scraper chain conveyors, includes a drive shaft. The drive power or the drive torque is introduced into the link chain by chain tooth elements. The chain tooth elements are set directly in the drive shaft in seats. For that purpose, the chain tooth elements have a lower coupling portion for interlocking engagement in the seats in the drive shaft. Accordingly, a separate chain wheel is unnecessary.
