【Abstract】 The project originates from the National Science and Technology Supporting Program, named“The Research on Cycloid Enveloping Planetary Precision Transmission”(No. 2006BAF01B08). Precision transmission is a kind of mechanical transmission mainly focuses on high-precision transmission of movement, it is widely used in many fields, such as weapon equipments, aviation and spaceflight, robot, NC machine tools, medical apparatus, transportation machinery printing , packaging machinery and so on. Precision transmission is an extremely important basic component in defense industry and the equipment manufacturing industry.Cycloid enveloping planetary transmission has advantages of multi-tooth meshing, high-precision of transmission; strong bearing capacity and high torsional stiffness. So it has been paid a wide rage of attention in the filed of precise transmission. This paper primarily studies contact strength and bulk temperature of the single and secondary enveloping cycloid meshing pair, which can provide a theoretical basis for the design of meshing pair, and has the practical engineering significance. The main contents of this thesis as follows:①According to principle of gears meshing kinematics method, conjugate theory of the single and secondary enveloping cycloid meshing pair has been introduced, and the meshing features, radius of curvature and comprehensive radius of curvature of the secondary enveloping cycloid enveloping planetary transmission have been discussed.②Based on Hertz, theoretical contact theory and the theory of cycloid enveloping planetary transmission, the contact strength of single and secondary enveloping cycloid meshing pair has been studied. Contact strength formulas have been derived, which can provide a theoretical basis and reference for the contact strength calculation and finite element analysis for cycloid enveloping planetary transmission.③Based on brief introduction of finite element method, the finite element models of secondary enveloping cycloid meshing pair and single-enveloping cycloid meshing pair are built and analyzed by ANSYS and APDL, and results are analyzed and compared.④According to gear meshing theory and the basic theory of hear transfer, the calculating method of thermal boundary conditions of body temperature filed analysis of single and secondary enveloping cycloid meshing pair are carried out. The body temperature filed of meshing pair is analyzed by ANSYS. ⑤Visual Basic 6.0 and APDL, which is a second development tool provided by ANSYS, are used to develop the program of tooth profile design and finite element analysis in cycloid enveloping planetary transmission. by using it, the integration, automation and parameterization of design and analysis of meshing pair is achieved.更多还原
