Different purposes gears characteristics studies during the design phase make possible to evaluate the design decisions quality. With use of the standard design approach based on state standards it is often unable to find the optimal design solution. The major problem occurs in the high-precision drive systems design based on the use of the wave gear drive as a drive output unit for the military and aerospace industry needs. In the paper a gears design methodology based on transmission geometric parameters selection and its characteristics analysis with finite element method was presented. Within the framework of wave gear torsional stiffness study, the wheel rotation angle relative to the flexible wave generator according vs. output torque diagram was presented. For cylindrical gears as a component of spacecraft drive as a fast and intermediate stage, impact assessment of selected geometric parameters on the transmission accuracy and load capacity was estimated. A modern manufacture methods review of gears designed by the proposed method with the use of rapid prototyping was present. The trial print results by means of rapid prototyping fine-grained spur gear with involute profile, made of stainless steel and titanium oxide was present. The current level 3d printing development can’t be obtained a quality of teeth side surface is required for special application high-precision drive systems. The overhaul results can be recommended for use in multi-stage gear units designing. The finite element methods usage will provide a visual stresses and strains distribution diagram of drive components at the design stage. The presented technique along with modern methods of gear technological implementation allows you to design not only the precision actuators for special purposes, for the needs of the military-industrial complex or the space industry, but also be used to analyze a wide range of general engineering programs.
