ROTARY ANODE X-RAY TUBE WITH A SLEEVE BEARING |
摘要 |
The invention relates to a rotary anode X-ray tube having a sliding bearing and a further bearing system. The further bearing system, preferably a magnetic bearing, is constructed so that it can absorb substantially entirely the axial and radial bearing forces, while the sliding bearing, which is preferably constructed as a spiral groove bearing with liquid metal lubrication, is shaped so that it absorbs the bearing forces only for a small fraction. It therefore has only a low friction, but it permits the supply of the anode current and especially an effective cooling of the anode disk. |
