Abstract
The link chain has links which are coupled together by connecting joint elements (2, 3), formed with end surfaces which transfer frictional forces between a cone disk and the chain. A plurality of links are coupled to these connecting joint elements which form an essentially uniform overall cross section, transferring force between the connecting joint elements and the links. In order to provide for uniform force transfer, some of the links (4, 5, 6, 6', 8, 9, 10) are strengthened with respect to others or 'normal', usually interiorly located links (1, 8). The strengthening can be obtained by using higher strength material, making the links thicker or doubling link elements to form a double-thickness link.
