【摘要】：谐波齿轮传动是在柔轮弹性形变理论基础上发展起来的新型传动，主要由柔轮、刚轮和波发生器组成。由于具有传动比大、结构简单、体积小、重量轻、传动效率高、承载能力大等特点，自谐波传动理论诞生以来就在航空航天、精密仪器、雷达和机器人领域得到广泛应用，近几年逐渐由军事领域向通用的机械产品领域发展。但是虽然一般传统的设计方法虽然能满足设计指标，但是设计效率低，成本高，周期长，限制了谐波齿轮传动技术的推广应用。我国虽然很早就开始谐波齿轮传动技术的研究工作，，但是至今仍未建立相关的规范或标准，未能形成产业化模式生产设计。因此对谐波齿轮减速器进行参数化设计，对实际设计有很好的实用价值。本文主要的研究内容如下：首先，对谐波齿轮传动的特点、应用领域及发展前景进行总结。阐述了对谐波齿轮减速器进行参数化设计的实际意义。其次，研究了利用UG平台与VC++软件结合的相关技术，对利用UG实现参数化设计的可行性进行分析，并实现谐波齿轮减速器进行参数化设计。完成谐波齿轮减速器啮合参数计算，编写相应的程序，再利用UG和VC++相结合进行UG二次开发。利用啮合算法算得的参数，对各个主要构件建立三维零件库，综合利用ADO和ODBC数据库接口技术实现数据库的存储、读取、增加等相关操作。最后，利用有限元分析软件ANSYS对谐波齿轮减速器的最主要构件柔轮简要进行有限元分析。对柔轮模型进行简化，设置优化参数后，合理进行网格划分，对柔轮进行模态分析和空载时受力分析。
[Abstract]:Harmonic gear transmission is a new type of transmission developed on the basis of flexible wheel elastic deformation theory. It is mainly composed of flexible wheel, rigid wheel and wave generator. Because of its high transmission ratio, simple structure, small volume, light weight and high transmission efficiency, harmonic gear transmission is a new type of transmission, which is mainly composed of flexible wheel, rigid wheel and wave generator. Since the birth of harmonic transmission theory, it has been widely used in the fields of aerospace, precision instruments, radar and robot. In recent years, it has gradually developed from the military field to the field of general mechanical products. But although the conventional design methods can meet the design targets, the design efficiency is low, the cost is high, and the period is long. Although the research work of harmonic gear transmission technology was started early in our country, there is still no relevant standard or standard. Therefore, the parameterized design of harmonic gear reducer has good practical value for practical design. The main contents of this paper are as follows:. Firstly, the characteristics, application field and development prospect of harmonic gear drive are summarized, and the practical significance of parameterized design of harmonic gear reducer is expounded. Secondly, the feasibility of parameterized design based on UG is analyzed by using the related technology of UG platform and VC software. The parametric design of harmonic gear reducer is realized. The meshing parameter calculation of harmonic gear reducer is completed, the corresponding program is compiled, and the UG secondary development is carried out by combining UG and VC. The parameters calculated by meshing algorithm are used. The 3D part library is established for each main component, and the database storage, reading, adding and other related operations are realized by using ADO and ODBC database interface technology. Finally, the finite element analysis software ANSYS is used to analyze the flexible wheel, which is the main component of harmonic gear reducer. Modal analysis and load analysis of flexible wheel are carried out.
