Modification of Cycloid Profile in RV320 Industrial Robot Reducer

RV320 reducer is specially used as industrial robots reducer High bearing capacity,small return difference and small volume etc.are required.The cycloid structure of mechanical structure can meet the requirements.The cycloid gear of the general structure uses standard profile,which has big clearance and return difference.They shall be improved when applied.After the analysis of modification of cycloid profile,it is concluded that the modification parameters can form more tooth.And clearance is formed between the valley of tooth,which forms oil film lubrication.Return difference is also narrowed Tests show that it can meet the needs of the high precision gear reducer.
