Flexible drive coupling with convoluted links

摘要

A flexible power transmission coupling wherein a drive member is connected to a driven member by a link assembly. The links are stacked and connected in series. Each link has a first end, a second end and an intermediate part. The first ends of each link are connected together and to the driven member, the second ends of each link are connected together and to a driven member or vice versa. The intermediate part of each link is convoluted and narrower than the ends. This allows greater axial and angular misalignments between drive and driven members. Also this results in a more linear relation between axial force and deflection of the coupling.
