摘要
指出将齿轮副作为高副来计算平面齿轮机构自由度是不全面的。通过实例分析平面齿轮副的约束度，认为将齿轮副作为瞬心副包含了高副约束和附加几何约束，在充分考虑由此带来的重复约束的前提下，对传统计算公式作了修正，为平面齿轮机构的设计提供了方便。
lt is incomplete to caculate the freedom of plane gear mechanism regarding gearpair as higher pair. The anal ysis on constrains of plane gear pair with practice examples indicates thatgear pair looking as instant center pair.containshigber and attached geometrical constrains. Considering the repeating constraint caused by it. the traditional formula is corrected. witch provides convenience for design of plane gear mechanish
