Aim To study the influence of the acceleration and the joggling factor between the pallet and the escape wheels on the timing characteristics of the clock mechanisms with unturned escapement. Methods The mathematics model and dynamic simulation software-WORKING MODEL 3D were used to build virtual prototype and to simulate the timing characteristics of the clock mechanisms with the unturned escapement in actual environments. Results Joggling factor among the escape wheels and the acceleration influence the timing characteristics of the clock mechanisms very deeply. Conclusion The reasonable values of the acceleration and the joggling factor among the escape wheels can improve the design efficiency of the clock mechanisms with unturned escapement.
