In a machine assembly, its performance (such as the axial clearence, the alignment error…) is usually determined by errors of concerned dimensions of a series of machine components linked up to form a "dimension loop". These dimensions are called loop members. One of the ways to guarantee the performance is to insert into the loop a compensating member, which is graded by its concerned dimension. During the assembling, the accumulative error of the loop members is measured and an appropriate grade...

In a machine assembly, its performance (such as the axial clearence, the alignment error…) is usually determined by errors of concerned dimensions of a series of machine components linked up to form a "dimension loop". These dimensions are called loop members. One of the ways to guarantee the performance is to insert into the loop a compensating member, which is graded by its concerned dimension. During the assembling, the accumulative error of the loop members is measured and an appropriate grade of the compensating member is determined to ensure the required performance. The article provides the mathematical analysis which tells how to determine the scope of this compensating dimension and its rational grading with known tolerence of loop members, as well as the number of compensating components of each grade needed in assembling as derived from the theory of probability. The article also provides an example of calculation.

分级调节装配的线性尺寸链解算原理是将调节环的公称尺寸视为变量,依据其它 各组成环的误差条件和装配技术要求,求解线性尺寸链,确定调节尺寸。具体解算过 程是.根据公差条件,求解一个极值尺寸链.得到一个极端条件下的调节尺寸并推算 出其它各级调节尺寸。由报算确定的另一极端条件的调节尺寸应满足相应条件的极值 尺寸链,并且封闭环公差应等于各组成环公差之和减去调节范围之差,由此来校核解 算结果。此外,调节环公差应取为封闭环公差之半为最佳.各级调节件的数量按统计 分析方法来确定。实例进一步归纳了解算过程
