Abstract
A double coupling comprising two flexible couplings are connected to each other through an intermediate hollow shaft and have outer parts on each and each with a hub and radially extending arms between which rubber blocks shaped as ring segments are inserted in a prestressed state. The rubber blocks each comprise a central, radially inwardly narrowing wedge to which two rubber members carrying plates on their free surfaces are symmetrically vulcanized on either side. The wedges are connected to corresponding claws of the intermediate shaft. The wedge and claws, along with the intermediate shaft serves as a common hub portion and form an inner part of the flexible coupling. One hub is secured to a solid shaft and the other hub is secured to a hollow shaft. The solid shaft extends through the hollow shaft and they move relative to each other, even in misaligned positions. As compared to similar prior art couplings for transmitting comparable power, the weight of such a doubling coupling is reduced.
