【Abstract】 The spatial cam sliding tooth transmission has the advantages of high transmission precision, adjustable meshing clearance and good self-lock characteristic. So as a new precision transmission device, it is provided with widely application prospects in many industry fields such as robot industry, machine industry, instrument industry, etc.The project originates from the National "863" Plan, named "The Research and Application on New Spatial Cycloid-Ball Gearing" (No. 2001AA423190). Study on the design theory and method of this new transmission is one of the important parts of this project. This thesis emphasizes on the mechanics feature of the spatial cam sliding tooth transmission, and the corresponding numerical computing software is developed. All of these offer a feasible method and prompt tool for the intensity design of the new precision transmission. Major contents of the thesis are as follows:1) Based on brief introduction of the profile theory about the spatial cam sliding tooth transmission, those formulas correlated to the mechanics feature are deduced to calculate the geometrical parameters;2) According to the Hertz contact theory in elastic-mechanics, the mechanics analysis model of the spatial cam sliding tooth transmission is built up; The deformation harmonizing conditions at each contact point are erected; The force analysis formulas of point contact are deduced and the resolution method is presented;3) The numerical calculating software about the deformation of the spatial cam sliding tooth transmission is developed; Using the software, the force characteristics of the spatial cam sliding tooth transmission are calculated with different design parameters; The general law on force characteristics of this transmission is obtained.4) The three-dimensional solid models of the spatial cam sliding tooth transmission are built up; The assembling and exploding on the solid modes of those components are made; The construction of this transmission device is described directly, and the checkout of the assembling coordination between the components of the spatial cam sliding tooth transmission can be done in the design stage. 5) Under the PRO/ENGINEER circumstance, the contact finite element analysis method of the spatial cam sliding tooth transmission are established; Using the I-DEAS software, the corresponding contact finite element analysis has been done. Comparing<WP=6>the result of the finite element analysis with the calculated result based on the Hertz theory, we find that they are accordant. 6) At the same time of the theoretic research, the design and manufacture of several model machines are accomplished with others.更多还原
