Thermal insulation effect of spherical contact surfaces in high vacuum
Abstract
A method to transmit large forces from one system to the other with minimal heat flow under high vacuum conditions (available in aerospace technology) is described. A mathematical treatment of the thermal contact resistance is given and experimental results are presented. An example of thermal decoupling of oblique ball bearings is given.
