ABSTRACT:
An elastic shaft coupling of the disk type in which the inner member is connected to one shaft and is affixed to an annular elastic (rubber) member by vulcanization. The rubber member is provided with an array of formations interdigitating with complementary formations of the outer member which is connected to the other shaft. The rubber body is retained against the outer member by pure radial precompression between the inner and outer members and progressively decreases in cross section radially outwardly, i.e. with increasing diameter, to maintain the shear stress substantially constant within the rubber member.
