The Kinematics Of RV-reducer And The Manufacturing Processes Of Its Components

RV (Rotate-Vector) the formation of reducer is built based on the structure of the less teeth difference cycloid gear planetary reduce and It is the two grade structure is composed of the front part of the involute planetary gear and the cycloid gear reducer after part, It not only has a compact size, high transmission efficiency, large range of transmission ratio, and it can bear heavy load, high precision, small hysteresis. At present, it is mainly used widely used in the articulated industrial robot joint reducer. Recently our country to the RV reducer is studied, including some universities and companies. The content of the research in the design and manufacturing technology is still not perfect, most of which is the theory research processing out of the prototype not to meet the requirements on strength, accuracy, return difference. Therefore in the industrial robot applications, its function is not up to the standard and can not replace the RV reducer. Up to now, The RV reducer in our country still can not get the approval of the marketIn the implementation of the issue, the project remove buy RV reducer (At present, the reputation of the international market is the best, the highest) and then use the method of reverse size, measurement of RV reducer parts size, three-dimensional modeling by Solidworks software.According to the relationship with the accuracy requirements of working conditions and the parts of RV reducer and assembly, the use of professional tools for manual work, important surface analysis, using CAXA software to draw the parts drawing; At the same time according to the analysis of parts materials and strength of cycloid gear, the materials and heat treatment of RV reducer parts to explore, and material properties of the core parts of the analysis; According to the common process of parts, the processing difficulties of reducer RV core parts in the exploration process, the existing problems deeply and solve, on the aspect of kinematics analysis of mechanism.Based on "cycloid pin gear planetary transmission" in parts of the materials and checking method, the above conclusion analyzes further analysis of the RV reducer, preparing for the design of pilot machine.
