摘　　要：为解决弹药加工中分时控制的问题,设计一款弹药加工高精密分度模型。根据主动轮轮廓面与从动轮滚子之间的运动规律,构建主从动轮之间的传动模型及其接触方程,通过主从动轮速度方向间的数学关系,给出压力角与从动轮向径之间参数关系,采用Creo参数化设计模块构建高精密分度机构模型,并通过实例验证了该设计模型的有效性。结果表明,该研究对于弹药转盘式加工和装药分度机构的设计具有一定的参考价值。To solve the problem about time-sharing controlling of ammunition parts manufacturing,design the precision indexing mechanism model of ammunition part manufacturing.Based on motion principle between contour surface of driving wheel and roller of driven wheel,both transmission model and contact equation were established between driving wheel and driven wheel.According to mathematical relationships for velocity direction located in contact point between driving and driven wheel,the parametric relationship between driving and driven wheel was deduced.The parametric design module of Creo software was employed to construct parametric design model of the higher precision indexing cam mechanism.The availability of design model was verified by design example.The results show that research has reference valuable for both ammunition rotary machining and charge ammunition manufacturing.
