Development Of Small Reducer Performance Test Platform

Small high-performance reducer has a lot of advantage, such as compact structure, small size, large transmission ratio, big output torque, as well as high precision. Those advantages made small high-performance reducer widely used in current high-tech areas, including robot,aerospace, intelligent medical devices, military industry and so on. In our country the related research on small reducer started late, so design theory is not yet mature. Small gear reducer has small module, the processing technology, in addition to the mechanical cutting more application of powder metallurgy and plastic forming technology, which makes the performance of the reducer is largely affected by the level of manufacturing technology.Immature design theory coupled with insufficient manufacturing technology level make the domestic small reducer’s development grown slower than expected. Moreover, there are lack of relevant test platform to test the performance of small reducer in our country, thus this paper has developed a test equipment independently. This device can test the performance of the newly designed small reducer, and analyze the experimental results to discover the reducer’s flaws in design and insufficient in performance which could have a very important significance on improving the deficiencies of design theory and manufacturing technology in this area.The subject carries out the plan of developing a test platform for small reducer independently which based on the school projects home-made equipment and consideration of teaching and research requirements in this regard. The main research work of this paper is aim to develop a test platform that could meet the demand of performance testing on a variety different types of small reducer, so there are three core requirements for this test platform,universal versatile, fast and accurate adjustment and high precision.According to the above requirements for the test platform, this paper has proposed a structure program which adopts the modular design for the platform and divided the overalltest platform into three modules, power source module, speed reducer module and load module. To meet the testing requirements and take into account the differences between different unit size and shaft methods of different reducer, this paper has improved and optimize the traditional method of playing table method detection device and designed a relevant adjustable device. After the complete of building platform, the dynamic load will have generated during testing, which makes testing and component connected to the connecting plate will be deformed. If the deformation is too large, it may makes coaxially between the axes, and which might unable to meet the requirements of the test. Thus, this paper has adopted Ansysworkbench to analyze its force and deformation, to ensure the reliability of the test work. Finally, in the actual reducer testing, this completed platform has been evaluated on both function and quality aspects. The results of this test shows this platform has good performance and high reliability.
