Raschet i vybor perekhodnykh posadok

The calculation and selection of transitional planting is important for fixed but detachable connections and to more accurately centered detail. The nature of landings determined by the probability of occurrence of these tightness and gaps. Calculations of the probability tightness and gaps based on the normal distribution of sizes of parts in manufacturing. Distribution of tightness and gaps in this case is also subject to the normal law, and the probability of their occurrence is determined by the integral function of probability. The probabilistic calculation of the mean value and dispersion of the gap or tension. How to configure, and in the processing of parts and machine operator adjuster stick closer to secure borders. For the hole is the smallest, and the shaft - the largest size limits. The result is that there is some asymmetry in the distribution of deviations of sizes.
