Sukov M. Substantiation of parameters of large-wave wave gears of drives of powerful machines

Scientific methods and means of increasing the load capacity of large-wave wave gears are considered. The force analysis of deformed gearing is based on physical and mathematical models that cover the three-dimensional force interaction of a flexible element in combinations of higher kinematic pairs. Studies of complex models have improved the accuracy of the results of three-dimensional quantitative and qualitative distribution of forces in the gearing, as well as allowed to determine the boundary conditions for the manifestation of interference and missing teeth. Studies of kinematic processes in the gearing of the wave transmission allowed to determine the velocities of the points of the flexible wheel in the radial and circular directions, the sliding speed of the teeth, to evaluate the gearing field by minimizing the sliding speed, wear and jamming of teeth, energy losses. The developed mathematical models of the stress-strain state of the flexible wheel in the form of a cylindrical shell clamped at the ends, gear and splined crowns connected by a cylindrical shell allowed to establish the stress distribution, as well as linear and angular deformations of the flexible wheel. The influence of design factors on interference and energy losses in gear transmission of wave transmission is established. The obtained results provided a significant reduction in energy losses and increased load capacity of large-wave wave reducers.
