Introduction

The goal of solving the problems is a deeper assimilation of the main theoretical positions and acquisition of skills for selecting fits for various joints of parts depending on their technical purpose, as well as improvement of skills for searching and using regulatory documents (GOST, ST CMEA, etc.) and tabular data.

Designations

D (d) - nominal diameter of hole and shaft

Dmax (dmax) - largest limit size of hole and shaft

Dmin (dmin) - smallest limit size of hole and shaft

EI - lower limit deviation of hole

ES- upper limit deviation of hole

ej- lower limit deviation of shaft

es - upper limit deviation of shaft

JT quota tolerance

TD (td) - inlet for manufacturing of hole or shaft

T (SN) - clearance or interference (landing tolerance)
