ABSTRACT:
A rotary anode stem tube is secured to a bearing by a coupling arrangement including a nested body and shaft, the shaft being thermally conductively coupled to the stem tube and the body being thermally conductively coupled to the bearing. The body and shaft have a relatively large interface region in facing spacing relation. Different positions of the interface region engage in thermally conductive relation in accordance with the temperature of the stem tube to selectively increase the thermal conductivity of the shaft to the body and selectively decrease the cooling time of the stem tube without an unacceptable increase in the bearing temperature.
