擒纵机构参数对钟表机构的计时散布影响研究

Timing Dispersion of Clock Mechanism with Parameter of Escapement Mechanism

针对某弹药定时机构计时散布大的问题,应用理论分析和计算机仿真的方法,研究了尺寸因素对计时的影响问题.在对钟表机构动力学理论分析的基础上,通过对机构进行三维建模和动力学仿真,得出了部分擒纵机构参数对钟表机构计时精度的影响.结果表明,擒纵轮齿顶圆直径与擒纵轮轴与摆轴中心距对钟表机构计时的散布影响较大.

Studies the timing dispersion of clock mechanisms by theoretical analysis and computer simulation. Based on dynamic analysis of the mechanism, 3D model building and dynamic simulation, influence of escapement mechanism parameter to timing of clock mechanisms is well understood. The result indicates that the diameter of escape wheel addendum, center distance of escape wheel and pendulum have their significant influence on the timing of clock mechanism.
