摘　　要：针对动、静涡旋体的加工制造中所需满足的几种关键形位公差指标进行了研究,得出了公差指标与机械摩擦及气体泄漏之间的关系;通过对比分析数值逼近法和展成法两种常见的加工方法,得出阿基米德螺线逼近法具有精度高、节点少、适用性高等优点。Several key indicators of shape and position tolerance were studied by aiming at requirements in processing and manufacturing of dynamic and static scroll body. Then the relationship of tolerance indicators, mechanical friction and gas leakage were pointed out. By comparatively analyzing the two common processing methods of numerical approximation and unfolding generation, it is concluded that Archimedes spiral approximation method has strongpoint of high precision, less node and high applicability, and etc.
