【 摘 要 】

At present, the volume of RV reducer has been limited to the volume calculation of cycloid gear, and the main transmission parts of RV reducer have not been fully calculated. In this paper, according to the structural characteristics and transmission principle of RV reducer, the volume calculation formula of the first decelerator sun gear, planetary gear, second decelerator cycloid gear, needle gear, crankshaft, Planetary frame I and planet frame II in the planetary frame are derived respectively, and the total volume formula of the RV reducer is calculated. The 3D model of RV reducer is built in SolidWorks, and the volume of the said parts is calculated by using relevant commands in SolidWorks. Comparing the volume calculated by the formula with the volume of the three dimensional model, the accuracy of the derived formula is verified. The error between the RV reducer volume calculated by the above formula and the volume of 3D model in SolidWorks is not more than 1.5%, and the maximum error of component volume contrast is 3.49%.
