Claims

[Claims for Utility Model Registration] 1. A large number of rollers made of heat-resistant metal are arranged in parallel inside a tunnel-shaped furnace body and pass through the furnace walls on both sides, and the object to be fired placed on the rollers is rotated in parallel. In the roller hearth kiln, which fires continuously while conveying the
On the outside of one of the furnace walls, a number of rotating shafts connected to a drive mechanism are freely supported for rotation only, and on the outside of the other furnace wall, support is provided concentrically with each of the rotating shafts and forming a pair with each other. The shafts are supported so as to be freely rotatable and freely movable in the axial direction, and the corresponding ends of both shafts have fitting holes that fit substantially tightly into the rollers, and slots are formed in the length direction. A connecting cylinder is provided, and a pair of pressing pieces made of an elastic material are attached to the connecting cylinder, and the pressing pieces are housed in the slotted circle and protrude into the fitting hole,
Retaining protrusions are provided protrudingly on the corresponding surfaces of the tips of both pressing pieces, and locking holes that fit into the engaging protrusions are formed on the outer circumferential surfaces of both ends of the roller, and both ends of the roller are connected to the connecting member. The rollers are freely attached to and detached from the shafts by fitting the pressing pieces elastically into the fitting holes of the cylinder and fitting the engaging protrusions into the locking holes. Features a roller support device for roller hearth kiln. 2. Utility model registration characterized in that the connecting cylinder has an outwardly inclined guide surface on the edge of the fitting hole, and the pair of pressing pieces each have an outwardly inclined guide part at the tip thereof. A roller support device for a roller hearth kiln according to claim 1.
