Abstract
A flexible shaft casing assembly for use in permanent installations wherein the flexible shaft may rotate at high speeds along a tight radius bend or bends in power driven application. The assembly includes a plurality of rigid, curved, tubular casing members which are capable of defining the bends. The casing members are provided with a flared portion at one end which secures a bearing member therein. The casing members are frictionally rotatable 360.degree. within each other by means of the flared portion of one engaging the non-flared portion of an adjacent casing member. Suitable high-temperature epoxy resin renders the bearing members secure in the flared portions of the casing members to provide a permanent installation.
