[0002] When the roller table adopts chain drive and the center distance between the two sprockets is relatively large, the chain on the running side of the driving sprocket is in a tensioned state, while the chain on the running side of the driving sprocket is in a loose state, and heavy loads are frequently started, braked and normalized. When reversing, the chain may loosen, especially after the chain is worn out, the possibility of loosening is greater, resulting in transmission failure and affecting the normal operation of the equipment, and the chain is difficult to install and debug when there is no tensioning device. It is not very convenient to disassemble the equipment during maintenance
The structure of the traditional tensioning device is relatively complicated, it takes up a large space, and it is inconvenient to adjust, so it is not suitable for use on the continuous casting roller table
