Research Of The Non-Centering Constant Velocity Universal Joint Based On The Spatial Machanism

As the development of the industry technology, the constant velocity universal joints must tend to be more in kinds and abroader in application. However, the research in this field is still lack of consummate theory system and new kinds of products with better character at present. So, it is useful and available to seek new mechanisms with more advantages by extending the research from centering to non-centering constant velocity.This thesis does structural analysis and constant velocity analysis for several kinds of universal joints, with the mathematic tools of the resolution of vectors and coordinates conversion. The similarity and the scope of application of the different constant velocity theories—centering theory and non-centering theory were obtained by doing the theoretical derivation, induction and summarization. What's more, the theory models' has extended in this thesis, which provides the theory guide for deeply research of the field of constant velocity umversal joints.With the application of the mathematics tool—the direction cosine matrices, the present non-centering universal joint is performed for the instant of the tripod universal joint with its output axle fixed with a self-aligning bearing. Based on the kinematics analysis, the complex dynamic analysis is done with the "single force pair" method. And the analysis results provide the data for the universal's parameter design and structural optimization.On the ground of the spatial constant velocity linkage mechanism, the completely calculation and deduce is performed to the staggered RCRCR mechanism. First, the dimension restraint relationship is deduced according to the condition that if the mechanism has its rotating shaft. Then, the constant velocity analysis is given for the...
