| Summary: | The increasing demands on the quality of machines, in
particular multipurpose CNC machines, determine the
tasks aimed at improving the designs of their critical
components. The aim of the work is to ensure the
accuracy, contact rigidity and durability of torquetransmitting connections of spindle assemblies during
reusable replacements of auxiliary tools based on the
use of conical profile connections with an equiaxed
contour. The paper presents the results of experimental
studies of these compounds on models that are made
of optically active materials, which allows us to visually
study the processes of contact interaction of profile parts
under cyclic loading conditions. The method of static
photoelasticity in the study of flat profile joints with an
equiaxed contour made it possible to establish based on
the analysis of isochrome patterns, that the change in the values of maximum tangential stresses per revolution of
the profile joint is subject to a pulsation cycle. |
