TORQUE TRANSMITTING MEMBER, COMBUSTION TURBINE ENGINE INCLUDING SAME, AND METHOD OF USE

摘要

Of The Invention A male-female spline coupling between two shafts includes a polymer spline insert removably carried by the female shaft. The spline insert engages with the female shaft in torque transmitting relation and defines a wear resistant spline surface engaging the male shaft to accommodate limited angular and radial misalignment while rotationally transmitting torque therebetween. The coupling includes provision for removal of the spline insert and replacement thereof with a fresh insert with a minimum of tools and in very short time. Tools for both removal and replacement of the spline insert are disclosed.
