Abstract
Abstract A rotary anode for X-ray tubes, wherein the rotary system consisting of the plate, rotor and bearings is connected by springs with the casing of the tube. The invention is particularly characterized in that the plate and the rotor are mounted upon an axle to which a rotary ring of each of two bearings is connected, while the other rotary ring engages a tube provided with springs which provide a connection with the casing and have their own frequency which is substantially less than the driving frequency.
