А quantitative estimate of uncertainty of the random scattering of the average clearance and interference in mating

Actual dimensions of suitable parts made according to the same drawings can fluctuate between the given limit dimensions, and the clearances and interferences in the conjugations — depending on the random scattering of the actual dimensions with the deviation of the shape of the real surface or...

description Actual dimensions of suitable parts made according to the same drawings can fluctuate between the given limit dimensions, and the clearances and interferences in the conjugations — depending on the random scattering of the actual dimensions with the deviation of the shape of the real surface or profile. The error of the shape of the real surface affects the probabilistic estimate of the results of sorting parts, leads to uncertainty in the size of the maximum of the material, a random scattering of the average clearance and interference in the mating and, as a consequence — the uncertainty to use all that come in for assembly of parts. The main result of the study is related with ensuring the receipt for the assembly of an equal number of parts, to the conclusion possessing novelty of the analytical dependences of finding a quantitative estimate of the uncertainty of the random scattering of the average clearance and interference in the mating, the random scattering of the average size relative to the upper and lower acceptance boundaries. Using the assembly method proposed with the initial reduction of real clearances and interferences in the mating by means of narrowing the tolerances of the actual dimensions to the tolerance of the shape of real surfaces in diametric terms within the random dispersion of the average size relative to the upper and lower acceptance boundaries allows to ensure the receipt on the assembly of an equal number of parts is achieved, including in the tested batches of parts with a breakdown of the tolerances of the actual dimensions into an equal number of dimensional groups.
