Abstract
In a shaft connecting structure, particularly suitable for fragile or brittle shafts of ceramic materials, used in high temperature environments such as conveyors in sintering furnaces, two shafts are connected in end-to-end driving relationship. Each shaft has one or more axial sector-sectional projections and sector-sectional grooves alternately formed at its end. The sector-sectional projections of each shaft enter the sector-sectional grooves of the other shaft, and the assembly of projections and grooves is clearance-fit in a cylindrical opening of a body which may be carried by the shafts or fixed to another structure.
