Shaft connecting structure

In a shaft connecting structure, particularly suitable for fragile or brittle shafts of ceramic materials, used in high temperature environments, two shafts 1a, 1b are connected in rotational driving relationship. Each shaft has one or more axial sector-shaped projections 3a, 3b and sector-shaped cu...

Zusammenfassung:	In a shaft connecting structure, particularly suitable for fragile or brittle shafts of ceramic materials, used in high temperature environments, two shafts 1a, 1b are connected in rotational driving relationship. Each shaft has one or more axial sector-shaped projections 3a, 3b and sector-shaped cut aways 4a, 4b alternately formed at its end. The sector- shaped projections of each shaft enter the sector-shaped cut aways of the other shaft, and the assembly of projections and grooves is clearance-fit in a cylindrical opening 6 of a body 5 which may be carried by the shafts or fixed to another structure. An axial gap (t, in fig 1a) may be provided between the two shafts to accommodate thermal expansion.
