Dynamic simulation of novel two-stage indexing cam mechanism
According to the topological structure of a novel two-stage indexing cam mechanism,the dynamics model is set up in the ADAMS environment,and the analysis is conducted on the output response.On this basis,efforts are made to explore the influence of such factors as the rotational speed,the inertia load,and the pin-gear distribution radius on the mechanism's dynam-ic performance.In addition,the analysis is carried out on the strength of the transmission component's pin gear.The results show that the amplitude of the output shaft's angular velocity increases significantly with the ever-growing rotational speed and de-creases with the ever-growing radius of the pin-gear distribution circle;its fluctuation amplitude decreases significantly with the ever-growing of the load.The dynamic meshing force between the pin gear and the cam during the indexing period of the mecha-nism fluctuates significantly.These results provide reference for parameter selection of such indexing mechanisms under different operating conditions.
