Special bearing and bearing composite construction for X ray tube

Abstract

A bearing dedicated for X-ray tube is composed of internal and external rings made of high-speed steel and with the channels puttered to form a compact MOS2 film as a lubricating layer, steel balls made of high-speed steel and coated with a silver layer by ionic method, and the holder made up of stainless steel 1Cr18Ni9 through punching and coated with a silver layer by electroplating. Such two bearings can be combined to form an assembly. It can reduce vibration and noise.

Description

Technical field: [0001] The invention relates to the technical field of bearing components, and relates to a special bearing for an X-ray tube and a bearing combination structure. Background technique: [0002] The performance and quality of the X-ray tube directly affect the important performance of the X-ray machine. The vibration, noise and life of its components are important technical indicators of the X-ray tube. It has a direct and direct relationship with the rolling bearing or bearing combination structure installed in the X-ray tube. close relationship. In the past, when domestic X-ray machines did not have strict requirements on the vibration index of X-ray tubes, the vibration value was between 3-9g, and the vibration value was scattered.

Problems solved by technology

In the past, when domestic X-ray machines did not have strict requirements on the vibration index of X-ray tubes, the vibration value was between 3-9g, and the vibration value was scattered. With the upgrading of products and the localization of CT tubes, and people's expectations The requirements of the medical working environment require a higher level of performance for the overall performance of the X-ray machine; therefore, higher requirements are put forward for the direct factor bearings and bearing combination structures that generate vibration, noise and affect life in X-ray tubes and CT tubes , so that the bearing assembly can adapt to a vacuum of 1×10 8 Torr, the working temperature is 400-500°C, the speed is 10000rpm, and the vibration of the whole tube is 1-2g, and the long-life work is difficult for general-purpose bearings.
