Since conventional metal alloys are most widely used in engineering structures compared to advanced composite materials, the joining of polymeric composite materials to metal alloy is very useful for the manufacturing of various engineering structures. Lee, in European Structural Integrity Society, 2003 INTRODUCTIONД¬arbon fiber-epoxy composite materials have been used in advanced engineering structures such as spacecraft, aircraft, automobile transmission shafts and robot structures because of their high specific stiffness and high specific strength. Couplings are further discussed in Section 11.3.14. Couplings are typically designed to accommodate some misalignment. Many applications require connecting one shaft to another axially. These items should be designed with the same factor of safety as other drive machinery components at the design operating loads. Keys, pins, and splines are important connections in shafts, designed to transmit power and torque. Per USACE, where spur gears are mounted on separate shafts, the relative slope of the shafts, at the centerline of the gear mesh, should not exceed one-third of the gear backlash divided by the smallest gear face width. The distance between bearings on shafting subject to bending, except that due to its own weight, should be such that the maximum bending moment deflection is limited to be fewer than 0.83В mm/m of shaft length at the maximum rated load. Shafts should be supported at locations necessary to minimize bending and axial movement, yet allowing for thermal expansion. A combined shock-and-fatigue factor of 1.25 is recommended for USACE projects. Stress concentration factors should be used where applicable.

The ASME shafting code requires additional stress reduction factors for keyways in the shaft. The design criteria for shafts follow the ASME shafting code equations with applied torsional and bending factors for heavy shock loading. In the United States, the ASME code is one of the approaches followed in design of transmission shafting.

In USACE projects, a factor of safety of 5 should be applied to shafts based upon the ultimate strength of the materials with the normal working load split equally between the winch units. Several references for shaft design include Refs. Intermediate bearings can be utilized to provide support and minimize the shaft diameter. To minimize both deflections and stresses, the shaft length should be kept as short as possible and any overhang minimized. Fatigue design should follow AASHTO and Shigley and Mischke. Shafting should be designed for the rated loads and increased by applicable shock and fatigue factors.

11.31, a torque limiting system was applied to limit the maximum torque or stall torque to 200% of the full-load torque. For this overload condition, unit stresses in components should not exceed 75% of the yield stress of the material and wire rope loads should not exceed 70% of the nominal breaking strength. At this condition, applying 70% of the stall torque to one side needs to be evaluated to determine if any components will yield. also requires an evaluation of the drive system for overload conditions at motor stall.
