Abstract:
In order to analyze the influencing factors of the high-speed cam system composed of a motor,a gear reducer and a cam mechanism,the system dynamic lumped parameter model is established by considering the motor,the stiffness excitation and error stimulation of the gear,the stiffness of the gear shaft and the cam follower stiffness,etc.The linear meshing stiffness and damp in the line of engagement are equivalent to the torsional stiffness and damp.The parametric analysis simulation is carried out using the software of Adams.The simulation results show that:the rotational inertia of the cam has great influence on the follower’s response;the response time of the follower delays 18% when the rotational inertia increases 10 times,and the follower is less affected by the environment;because the proportion of the cam inertia load is larger,the stable external load has little effect on the cam;compared with no-load condition,the response time of the follower delays 3 milliseconds under the load condition;the impact load has more effect on the follower response;the gear mesh stiffness and shaft stiffness have little effect on the cam follower in small power cases.
