  • CONTROLLING SHAFT BENDING MOMENT AND WHIPPING IN A TENDON DEFLECTION OR OTHER TENDON SYSTEM
    Publication number: 20090264818
    Abstract: A tendon deflection system including a shaft, a plurality of tendons movably disposed within the shaft, and a force-balancing element coupled to the tendons. In a first section, the plurality of tendons are arranged around the shaft at equal angles to each other and at an equal distance from the center of the shaft. The tendons operating in concert with the force-balancing element minimize the moment expressed in the first section. The second section is deflectable and includes at least one tendon, extending from the plurality of tendons in the first section, which is arranged along one side of the shaft such that the bending moment expressed in the second section is greater than the first section.
