DRIVE CONNECTION WITH INTEGRATED CHAIN TENSIONING APPARATUS FOR FACE CONVEYORS

摘要

A drive connection is disclosed. The drive connection may be configured to be interconnected between a main driving unit and a main gear unit of a driving device configured to drive a chain of a conveyor of a longwall device. The drive connection may have a housing configured to be connected to the main driving unit and to the main gear unit. The drive connection may also have a drive shaft disposed within the housing and configured to transmit torque from the main driving unit to the main gear unit. In addition, the drive connection may have a chain tensioning apparatus disposed within the housing. The chain tensioning apparatus may have a worm drive interacting with the drive shaft. The chain tensioning apparatus may be configured to drive the drive shaft for tensioning the chain of the conveyor when the main driving unit is in a non-operative state.
