The Design and Dynamics Analysis of Cylindrical Roller Surface Unfolding Mechanism
In order to design an efficient and stable cylindrical rollers surface unfolding mechanism,and know about the motion of the cylindrical rollers surface during the unfolding process.The surface unfolding model of the cylindrical roller is established.The time taken for roller to achieve the uniform rotation and the rollers vibration on the direction of x-axis are used to evaluate the roller unfolding effect.The factors affecting the roller unfolding efficiency and the unfolding stability are determined.The roller accelerating time-consuming equation and the deformation equations of the unfolding wheel are established.The dynamics of the surface unfolding model for the cylindrical roller is studied.The simulation of the roller unfolding motion is carried out by the Adams software to the roller which is U32 52 mm.The simulation results are consistent with the theoretical analysis results.In the roller surface unfolding process,the roller accelerates firstly,the vibration of roller is large,and then the uniform rotation is achieved,and the vibration of roller is small.According to the simulation data,the influence of the material of the unfolding wheel,the bottom radius of the unfolding wheel and the minimum distance between the outer edges of the two unrolling wheels on the stability and unfolding efficiency of the roller unfolding motion are determined.It is concluded that the bottom radius of the unfolding wheel is 16 mm,the material is silicone rubber and the minimum distance between the outer edges of the two unfolding wheels is 8 mm,the cylindrical roller has the best unfolding effect.According to the simulation results,the cylindrical roller surface unfolding mechanism is designed to meet the requirements of use,and the rationality of the cylindrical roller surface unfolding model is verified.It provides a theoretical basis for the research of the surface unfolding equipment for the column workpieces.
