Abstract
Link for chain having an extent about an aperture defines a section which is wider near the inside with the section being usually concave outward on each side, A junction link comprises a C member and a bridging member with a cross section generally similar to the link. A method of assembling the bridging member to the C member involves providing two pairs of aligned apertures. In each pair a rivet like member with a head end and a free end has its free end inserted through the aligned apertures, after which a head is formed on the free end by arc welding.
Claims10
Link of substantially circular shape for a rotary kiln chain,
- having an extent, extending about most of the circular shape of substantially uniform cross section,
- said extent defining a section wider at the inside than outside said section having opposite sides defining outwardly facing concavities,
- and said section defining a radial thickness and said link having a maximum axial thickness,
- said section defining a radial thickness greater than the link's maximum axial thickness.
Link of substantially circular shape for a rotary kiln chain,
- having an extent, extending about most of the circular shape,
- said circle defining link aperture and aperture diameter,
- said extent having a section wider at the inside than the outside,
- said section defining a radial thickness,
- said radial thickness being about 40% of said link aperture diameter.
Link of substantially circular shape defining an annulus radial extent and a central opening diameter when said radial extent is about 40% of the central opening diameter.
Link of substantially circular shape for a rotary kiln chain,
- having an extent, extending about most of said circular shape of substantially uniform cross section,
- said cross-section defining an inner contour,
- said extent defining an inner aperture,
- the radius of said inner aperture being substantially greater than the radius of said inner contour.
Link of substantially circular shape for a rotary kiln chain,
- having an extent, extending about most of said circle of substantially uniform cross section,
- said cross section defining a straight inner taper meeting a lesser straight outer taper whereby a concavity is defined where said tapers meet.
