Dynamic Balance Optimization Strategy of Gear Shaper Main Motion Mechanism
The main movement of the gear shaper is achieved by means of a crank slider mechanism.Be-cause the mass centers of crank pin and connecting rod do not coincide with the rotating centers,the unbal-anced inertia force will be produced during the process of gear insertion.Vibration and noise of the lathe will cause,and the improvement of gear insertion machining accuracy will be restricted.Therefore,the mass equivalent analysis of the crank pin and connecting rod was carried out to calculate the total unbalance between the crank pin and connecting rod when the crank rotates once.In order to obtain the optimal bal-ance effect,it adopted an optimization strategy that integral solution and mean solution were two optimiza-tion calculation methods and mean variance was evaluation index.The calculation of dynamic balance of main movement mechanism of gear shaper YKW51160 shows that the unbalance of balancing block calcu-lated by integral optimization method is similar to that calculated by mean optimization method.and the fluctuation of unbalance after integral optimization is smaller and the vibration reduction effect is better.
