We propose a computational scheme for calculating the temperature
and the heat flow sharing coefficient at indentation of the end
of a thin pin into the lateral surface of a rapidly rotating ring.
It is supposed that on free lateral and end surfaces of the ring,
as well as on the lateral surface of the pin, heat exchange by
the Newton law occurs. The two-dimensional mixed quasi-stationary
heat conduction problem for the ring has been solved by means of
the finite integral Fourier transform. Formulas for calculating
the temperature on the ring surface have been derived, and from
the condition of equality of the average temperatures in the
friction zone of the ring and the pin, the heat flow sharing
coefficient has been determined. The influence of the ring thickness
and its inner surface cooling on the maximum temperature has been
investigated.
