On The Loading Capacity And Error Analysis Of Spatial Multi-congjucate Transmission Mechanism

The spatial multiple conjugate transmission mechanism transfers movement and powerby more conjugate surface mesh at the same time. Multiple contains more conjugate and theconnotation of interactive envelope at the same time. Through multiple space meshing,multiple conjugate transmission mechanism has very significant advantages: flexible structuredesign, stable transmission, compact structure, high transmission efficiency and high contactratio and so on. But due to the complexity of design calculation, processing difficulties, whichtransmission performance is difficult to meet the design requirements, and it have no accuracyevaluation system, multiple conjugate transmission mechanism has been restricting itsdevelopment. In this paper, based on the related theory and technology research to overcomethe above bottlenecks, promote its popularization and application.Tthe research background of the mechanism is elaborated, the definition of the spatialmultiple conjugate transmission mechanism has been given. The relationship between spatialmeshing theory and the multiple conjugate transmission mechanism is analyzed. This paperexpounds the research development of the multiple conjugate transmission mechanism’s staticload and dynamic, and the error analysis and comprehensive research development. Theproblem is in urgent to solve were analyzed, and the research content of this paper is givenaccordingly.The knowledge of differential geometry, coordinate transformation and space conjugateconditions such as knowledge used in the paper were first introduced. Then, the meshingcondition of the multiple conjugate transmission mechanism was derived. The meshing anddigital simulation model of the globoidal cam and the toroidal drive were established. Studyon the spatial multiple conjugate cylindrical end cam was developed for its engineeringapplication. At the same time the building method of the error equation of conjugate curvedsurface was also studied.The load distribution model was built when multiple conjugate transmission mechanismwas meshing by2or more contacts between two congjuate parts, And based on this model,study of toroidal drive pressure angle changes, studied the body meshing gear contact fatiguestrength and fatigue strength calibration method.Based on the established multiple conjugate meshing model and meshing with errormodel, develop multiple conjugate transmission mechanism’s error analysis and synthesis,and by the toroidal drive and globoidal cam, studies to establish their accuracy systemmethod. First of all, build the dynamic model of the toroidal drive, add error in it, and the error ofimpact on the natural frequency of the toroidal drive was developed.Spiral angle including error was substituted in normal force calculation formula. Bymatlab programming, using the different value of error, the influence of error on the toothsurface normal force calculation and analysis were developed. By studying multiple conjugate,coefficient of load balancing were developed, the influence of the accuracy is helpful to theresearch of the mechanism.Summary and outlook to the front of the content, improve the understanding of researchmethods and content, the content of the research for to continue were had a more profoundunderstanding.With multiple conjugate transmission mechanism error analysis as the main target, thedevelopment of the meshing theory analysis to establish the digital meshing model, static anddynamic load analysis of the mechanism and the product trial research, has carried on thebeneficial and effective exploration for dealing with its the engineering application problem...
