【摘要】：小型精密减速器具有结构紧凑、体型小、传动比和输出扭矩大、精度高等诸多优点,因而在当前的机器人、航空航天、现代智能医疗器械、军事工业等高科技领域广泛运用。国内对小型减速器这方面研究起步较晚,因而在这方面的设计理论尚不成熟。并且小型减速器由于齿轮模数小、加工工艺除了机械切削,更多地应用粉末冶金以及注塑成形技术,这使得减速器的性能很大程度上受制造工艺水平的影响。设计理论的不成熟再加上制造工艺水平的不足,这两大因素使得国产的小型减速器的实际工作性能和理论设计预期是有比较大的出入的。而国内并没有很好相关的针对小型减速器性能测试的平台,因而自主开发一套相应的检测装置,对设计加工出的小型减速器进行性能检测,然后通过对实验检测结果进行分析总结来发现其性能上的不足和设计上的缺陷,这对完善我国在小型减速器设计理论方面不足和提升在这方面的制造技术是有着非常重大意义的。本课题正是基于这方面的考虑以及科研教学要求并依托学校自制设备项目而提出的。论文主要研究工作是为了满足多种不同类型小型减速器的性能测试工作,因此对测试平台提出了通用性强、调节快速准确、测试精度高这三大核心要求。根据测试平台的功能要求提出了将测试平台进行模块化设计的结构方案,将整体测试平台分为动力源模块、减速器模块和负载模块。考虑到不同类型减速器的体型、出轴方式等差异,为了满足测试要求对传统打表法同轴度检测装置进行改进和优化并设计了相配套的调位装置。在平台搭建好后,由于在进行测试工作时会有动载荷的产生,这会使与测试元器件相连接的连接板会发生形变,如果形变过大可能会使得各连接轴之间的同轴度偏差过大而无法满足测试要求,因此使用Ansysworkbench对其进行受力形变分析,从而确保测试工作的可靠性。最后在实际的减速器测试工作中,对设计好的小型减速器测试平台在功能和质量两大方面进行评估,结果表明此测试平台整体性能良好,可靠性高。
[Abstract]:Small precision reducer has many advantages, such as compact structure, small size, large transmission ratio and output torque, high precision and so on, so it has many advantages in the current robot, aerospace, modern intelligent medical equipment. Military industry and other high-tech fields are widely used. The domestic research on the small speed reducer started late, so the design theory in this field is not mature. And the small gear module of the small reducer is small. In addition to mechanical cutting, more application of powder metallurgy and injection molding technology. This makes the performance of the reducer greatly affected by the manufacturing process level. These two factors make the actual performance of domestic small reducer and theoretical design expected to be quite different. However, there is no good related platform for the performance test of small reducer in China. Therefore, we develop a set of corresponding detection device to test the performance of the small speed reducer designed and processed, and then through the analysis and summary of the experimental results to find its performance deficiencies and design defects. It is of great significance to perfect the theory of small reducer design in our country and to improve the manufacturing technology in this field. This subject is based on the consideration of this aspect and the requirement of scientific research teaching and depends on the school. The main research work of this paper is to meet the performance test work of many different types of small speed reducers. Therefore, three key requirements of the test platform are put forward, which are universal, fast and accurate adjustment and high test precision. According to the functional requirements of the test platform, the structural scheme of modularized design of the test platform is put forward. The whole test platform is divided into power source module, reducer module and load module. In order to meet the test requirements, the traditional tabulation method coaxiality detection device is improved and optimized, and a matching adjusting device is designed. After the platform is built, there will be dynamic load in the test work. This will result in deformation of the connecting plate connected with the test components, if the deformation is too large, the coaxiality deviation between the connecting axes will be too large to meet the test requirements. Therefore, Ansysworkbench is used to analyze the mechanical deformation to ensure the reliability of the testing work. Finally, in the actual reducer testing work. The function and quality of the small reducer test platform are evaluated. The results show that the test platform has good performance and high reliability.
