Calculation and a choice of transitional landings are important for fixed, but portable units and for more exact centring of details. Character of landings is determined by the probability of creation in them pulls and gaps.
\nCalculations of pulls and gaps probability are the base on normal details sizes\u2019 distribution during their production. Distribution of pulls and gaps in this case is also done according to the normal law, and probability of their creation is determined by means of probability integral function. At the credible calculation we determine a mean of value and dispersion of gap or pull. At the installation and at the fixing of details both fixer and machine-operator keep near to the safe limits. For the opening hole it is the least and for the shaft are the maximum size limits. As a result, there is some asymmetry in the distribution of sizes\u2019 deviations.<\/p>\n

Key words: transitional landings, gap, pull, mean of gap value (pull value), a credible dispersion, the most and the least of credible gaps and pulls, Laplace\u2019s function, standard of deviations, maximum and credible gaps, landing\u2019s admittance.<\/p>\n
