Abstract: The
kinetic precision of transmission chain is a key problem in the
research of gear cutting machine transmission system. The
traditional point of view is to consider the transmission chain
as a geometrical meshing system, thus it is deemed that the
kinetic precision of the transmission chain only depends on the
manufacturing and assembly errors of its transmission parts. But
further research reveals that the kinetic precision of
transmission system is closely related with the system dynamic
effects. Therefore, from the dynamic point of view, it is
discerned that not only deems the transmission chain as a
geometrical meshing system but also considers it as a dynamic
system performing with torsional vibration. On the basis of
analyses and processes of measuring data of samples from tests
of cutting machine's kinetic precision of transmission chain,
the results represent that the influences of dynamic
characteristics of the transmission system on its kinetic
precision is non-negligible. Experimental methods for discerning
the transfer function of torsional vibration of gear
transmission system and experimental results have been given.
