摘　　要：装配过程中对修配环进行修配是补偿和协调装配累积误差的有效方法之一。为了满足封闭环的装配要求,修配量应当有一个极限值。本文首先分析修配环修配时影响封闭环的四种情况,分别推导了这四种情况下修配环最大修配量计算公式,其结果相同。本公式有助于装配过程申对修配环进行合理的修配。Repair method can make repair-chain redeem assembly-stack error in the process of product assembly. But repair value must meet the requirement or restriction from assembly requirements of close-chain. The paper analyzes four cases that repair influences close-chain, and deduced the formulae for computing the maximal repair-value of four cases, and these formulae are the same. This formula helps appropriate repair of repair chain.
