ABSTRACT:
A roller driving apparatus for use in a roller hearth kiln has a kiln tunnel and kiln side walls. The apparatus includes a rotary drive shaft, a holder fixedly mounted at one end thereof on the rotary drive shaft, a metal connection pipe detachably mounted on the other end of the holder and including a positioning aperture formed therein, a ceramic roller, and a metallic receiver roller rotatably supporting the driven end of the ceramic roller through a metallic coil spring. The positioning aperture extends along the longitudinal axis of the connection pipe, and the ceramic roller is mounted at a drive end thereof on an end of the connection pipe opposite to the holder for receiving drive power from the rotary drive shaft. The ceramic roller has another, driven end, and extends through the kiln tunnel through one of the kiln side walls of the roller hearth kiln. An engaging arrangement is fixedly mounted at one end of the holder, for selectively engaging with the positioning aperture of the connection pipe, and the metallic coil spring is wound on an outer periphery of the driven end of the ceramic roller.
