Abstract

This paper discusses a method for improving the kinematic accuracy of gear trains through precise analysis and decomposition of the errors of individual gears during assembly. Through mathematical modeling and analysis of collected data, the optimal meshing of the gear wheels is determined, allowing for the minimization of the total error.
