Rotary anode bearing for X=ray tube - has roller bearing which is loaded with axially directed force to eliminate bearing play using magnetic parts mounted on end wall of vacuum tube and rotating shaft respectively.

摘要

Permanent magnets (14,15) produce an axially directed force, and each are associated with a ferromagnetic parts (6,11) to form magnetic components. One magnetic component (14,6) is connected to the rotary axis (1) and the other (15,11) with the vacuum housing (2) of the X-ray tube. The shaft (6) or a section of the vacuum housing (2) form the ferromagnetic components (6,11). The fixed bearing acts as a roller bearing and has a static loose magnet bearing. USE/ADVANTAGE - Simple construction.
