RV reducer,as a precise transmission mechanism for the joint motion of industrial robots,plays a very important role in completing the target tasks of the robot.Taking the cycloid wheel as the research object,the transmission principle and structure of the RV reducer are introduced.Through the study of the parameter equation of the standard theoretical tooth profile cycloid curve,the expression of the parameter equation is simplified,and the parametric modeling is carried out with SolidWorks.The three-dimensional physical sample of the cycloid wheel manufactured by the method of fusion accumulation rapid prototyping has high surface accuracy and sample size accuracy,which is beneficial to provide feasible help for the research and development of various parts of the RV reducer in the later period.
