Abstract：[Objective]In order to improve the performance indicators of precision reducers for industrial robots,a type of abnormal cycloidal planetary reducer structure was proposed based on the existing transmission principles of reducers.[Methods]Using SolidWorks software,a three-dimensional structural model of the reducer was established,the force analysis and strength verification on its meshing parts were conducted,and the theoretical calculation of transmission efficiency was conducted.Virtual simulation of angular velocity,meshing force,and transmission efficiency was conducted using Adams simulation software.Prototype tests were conducted,and the performance indicators were compared and analyzed with those of domestic precision cycloidal planetary reducers of the same model.[Results]The results show that the transmission principle of the developed prototype of the abnormal cycloidal planetary reducer is feasible,and the performance indicators such as transmission error and transmission efficiency of the reducer basically meet the national standard requirements.
