The large gear is generally installed in the kiln or near the end of the kiln. This is to reduce the torque of the cylinder, reduce the thermal effect of the cylinder on the transmission, and reduce the intrusion of dust at both ends. The appropriate distance between the large gear and the tire is about 3 meters. Because it is not easy to bend when it is close to the cylinder of the tire, it is easy to ensure the correct meshing of the large and small gears. If the distance is too small, it is not convenient for installation and maintenance.
There are three ways to install the large gear on the cylinder: tangential and longitudinal spring plate installation, and rigid connection with the cylinder.
