Introduction
When a designer wishes to choose a shaft and hole deviation and
tolerances, as, for example, an interference fit, he may be led to
assume, when reading B.S.1916, that a particular fit combination
will give the same functional characteristics over the entire size
range covered by the standard.
It is the intention of this note to show that this assumption is
not necessarily valid, and that the fit combination_ required to meet
a particular functional requirement will vary with size, These
comments are not intended as a criticsm of the standard as such but,
rather, that a supplement to the standard is required, to give the
designer guidance on the choice of fit for particular functional
requirements. |
