ROTATING UNIT OF A MEDICAL IMAGING DEVICE WITH A HYDROSTATIC SLIDE BEARING AND AN INTEGRATED COOLANT CONDUIT

摘要

A rotating unit of a medical imaging device has a hydrostatic slide bearing and an integrated coolant conduit. The rotating unit includes at least one stator, at least one rotor that is borne such that it can rotate relative to the stator, and at least one portion of a circulation system for the circulation of a bearing medium, so the rotor is borne hydrostatically floating by the bearing medium. The at least one portion of the circulation system for the circulation of the bearing medium also has at least one stator-side opening and one rotor-side opening to the hydrostatic slide bearing. The rotating unit additionally has at least one at least single-channel rotary joint mounted between the rotor and the stator. The rotating unit is designed such that the bearing medium can be supplied through the stator-side opening into the hydrostatic slide bearing and the bearing medium can be supplied again through the rotor-side opening and the rotary joint into the circulation system again.

主权项

1. A rotating unit of a medical imaging apparatus, comprising:
a stator; a rotor mounted for rotation relative to said stator; a portion of a circulation system that circulates a bearing medium in a gap between said stator and said rotor in which said rotor hydrostatically floats so as to the rotatable relative to said stator; a single-channel rotatory joint between said rotor and said stator; said portion of said circulation system comprising a stator-side opening and a rotor-side opening in fluid communication with said bearing medium and said rotary joint, said portion of said circulation system being configured to cause said bearing medium to be supplied through said stator-side opening into said gap and to be supplied from said rotor-side opening and said rotary joint into a remainder of said circulation system, allowing said bearing medium to flow through said portion of said circulation system.
