Abstract
The ultra large aspect ratio gear structure is increasingly widely used in gearboxes for aerospace, high-speed equipment, and heavy equipment to meet the performance requirements of narrow center distance and high torque. The conventional gear specification calculation accuracy is difficult to meet the performance requirements of ultra large aspect ratio gears. The article comprehensively summarizes the current mainstream methods for gear modification and dynamic performance research. It is recommended to use the finite element method to calculate the bending deformation, shear deformation, compression deformation, gear matrix deformation, Hertz contact deformation, and gear meshing stiffness of the gear teeth, coupled with the bending and torsional deformation of the gear shaft under bearing constraints. In the presence of uncertain factors such as manufacturing and installation, accurate gear contact deformation and modification results can be calculated. Furthermore, a robust optimization method for uncertain systems is adopted to reduce the transmission error fluctuations of gears from the source of gearbox vibration, in order to achieve robust dynamic optimization effects.
