On a new cycloidal planetary gear used to fit mechatronic systems of RES

The paper deals with a new variant of a cycloidal planetary transmission (CPT) with modified structure, proposed by the authors, able to accomplish high kinematical ratio and high efficiency, useful to fit mechatronic systems of renewable energy systems (RES). Through the conceptual design approach, six new transmission variants were generated and the principle solution was established. Further on, optimization studies on the geometrical features and dynamic behavior of the new planetary gear were performed. Based on a physical prototype and using a modern high-tech stand, experimental researches on the efficiency of the new cycloidal transmission tested as reducer were performed. The obtained experimental results comply with the theoretical model, and some performance features of the transmission prototype are thus derived.
