Abstract : The patent describes a cable traction sheave comprising a metal sheave body fixed to a rotatable hydraulic motor housing and having a novel cable groove liner. The liner is formed of a solid elastomeric and has a band of pressure release material that permits deformation of the liner so as to increase lateral pressure on the cable to preserve the round shape thereof and increase gripping of the cable by the liner. An alternative embodiment comprises spring elements embedded in an elastomeric liner and configured to cause the liner to grip the cable in response to cable pressure. The device is designed for submarine-towed devices.
