Induced Oscillations in Worm-Gear Drives of Rotary-Type Manufacturing Machines

Abstract

Induced oscillations in the electromechanical worm-gear drives of rotary-type manufacturing machines are investigated. Using two design models, viz., a model with rigid linkages and a model that accounts for elastic linkages, natural frequencies have been determined and amplitude-frequency characteristics have been constructed. An asynchronous drive motor is described by the dynamic characteristic. A comparison of the results calculated using two models has established the range of the initial parameters within which the dependences can be used that were obtained from the simplest design model with rigid linkages. This will allow considerable simplification and reduction in the time of synthesizing the drive under consideration.
