Connecting coupling bearing of thermal insulating X-Ray tube

Abstract

The invention discloses a connecting coupling bearing of a thermal insulating X-Ray tube. The bearing comprises a connecting coupling bearing composed of a connecting flange and a shaft lever. The bearing is characterized in that a thermal insulating ceramic device is arranged at the contact surface between the connecting flange and a tungsten disc of a CT machine. The thermal insulating ceramic device is arranged at the contact surface between the connecting flange and the tungsten disc of the CT machine, so that when the CT machine works, the tungsten disc emits heat, the heat of the tungsten disc transmitted to the coupling bearing is reduced, and thus the heating of the coupling bearing is alleviated, and the heating expansion and cooling contraction coefficient of the coupling bearing is reduced; therefore, the transmission accuracy of the coupling bearing is guaranteed, the service life of the coupling bearing is prolonged and the machine maintenance cost is saved.

Description

technical field [0001] The invention relates to a shaft-connected bearing, in particular to a heat-insulated X-ray tube-connected shaft-connected bearing, which is mainly used for connecting X-ray tubes of CT machines in hospitals. Background technique [0002] At present, the X-ray tubes of hospital CT machines are connected by shaft-connected bearings. The main structure includes the connecting shaft-connected bearings installed in the X-ray tubes. The flange end of the shaft-connected bearings is directly connected to the tungsten disc of the CT machine through screws. , the shaft part of the shaft-connected bearing is combined in the anode rod of the X-ray tube. When the CT machine is working, it must first heat the tungsten disc of the X-ray tube in a vacuum state until it turns red, causing the anode rod and the bearing to heat up (transmitted to the bearing The temperature is about 600 degrees), and the film can be taken. The heat of the tungsten plate is directly tra...

When the CT machine is working, it must first heat the tungsten disc of the X-ray tube in a vacuum state until it turns red, causing the anode rod and the bearing to heat up (transmitted to the bearing The temperature is about 600 degrees), and the film can be taken. The heat of the tungsten plate is directly transmitted to the shaft-connected bearing, causing the shaft-connected bearing to heat up and expand, and then shrink after cooling, which affects the accuracy coefficient and service life of the shaft-connected bearing.
