Abstract

The machine parts assembly method based on determining minimum values of the absolute deviations of linear dimensions from the nominal dimension is proposed. Searching methods, ensuring assembling accuracy is an important issue of mechanical engineering technology. It is proved for existing distribution laws of random variables – linear dimensions that the variance of the minimum value of the absolute deviations of the linear dimensions from the nominal dimension is ten times smaller than the variance of the random variable – linear dimension. It was found that high accuracy is achieved by the ordered arrangement of the values of the absolute deviation of the linear dimension from the nominal dimension and a selection of two machine parts with a minimum of these values for the assembly. This method will allow to ensure high assembling accuracy by the linear dimension parameter. This method can be used for a small statistical sample as well.
