CHAIN DRIVE FOR LINK CHAINS OF MINING CONVEYORS OR MINING EXTRACTION MACHINES

摘要

The invention relates to a chain drive (1) for link chains (2) of mining conveyors or mining extraction machines, in particular for scraper chain conveyors. The chain drive (1) comprises a drive shaft (3). The drive power or the drive torque is introduced into the link chain (2) by chain tooth elements (4). According to the invention the chain toothed elements (4) are set directly in the drive shaft (3) in seats (6). For that purpose the chain tooth elements (4) have a lower coupling portion (8) for interlocking engagement in the seats (6) in the drive shaft (3). According to the invention a separate chain wheel is unnecessary.
