Dynamic Analysis Of The New-type Four-ring-type Cycloid Drive

Double crank four ring-plate-type cycloid drive is a new-type drive. After analyzing the merits and the shortcomings of involute gear ring-plate drive and traditional cycloid drive each, we proposed the double crank four ring-plate-type cycloid drive, which possess the merits of small volume, light weight, wide range of transmission ratio, high efficiency, uniform operating, well knit-structure, high load-capacity. Because double crank four ring-plate-type cycloid drive is still at the stage of studying, its design and manufacture lack the reliable theoretical foundation, it is extremely meaningful for mechanical industry to study its dynamics, to analyze the vibration mechanism, to present the measures to improve performance, and to design planetary gear trains with super performance. This dissertation mainly explores the dynamics of the double crank four ring-plate-type cycloid drive.Applied lumped parameter method of the double crank four ring-plate-type cycloid drive, according to different characteristics of each component, and the degree of freedom of the different quantities separately are considered, the elastodynamics equation of the system was built in this paper. And stiffness, such as component bearings and gear meshing interactions, are considered. Developing the systematic dynamics equation and carrying on the proper transformation to the equation, can get the dynamics equation which include such factors as involute gears mesh stiffness, planetary bearing rigidity, output and input shaft bearing rigidity and meshing rigidity, etc. The equation can be used to calculate the natural frequency of the sample. Analyzing the dynamics characteristic of the double crank four ring-plate-type drive, improves its dynamic characteristic and sets up the solid theory analytical method.A closed-form numerical algorithm for the periodic dynamic response of the symmetry system is developed based on real modal analysis using MATLAB.
