Tóm tắt

 Articulated splines are commonly used in the planetary stage of wind turbine gearboxes for transmitting the driving torque and improving load sharing. Direct measurement of spline loads and performance is extremely challenging because of limited accessibility. This paper presents an analytical model for the analysis of articulated spline coupling designs. For a given torque and shaft misalignment, this analytical model quickly yields insights into relationships between the spline design parameters and resulting loads
  bending, contact, and shear stresses
  and safety factors considering various heat treatment methods. Comparisons of this analytical model against previously published computational approaches are also presented.
