Title:
DYNAMIC PRESSURE THRUST BEARING
Document Type and Number:
WIPO Patent Application WO/2022/160680
Kind Code:
A1
Abstract:
A dynamic pressure thrust bearing, relating to the technical field of bearings. The dynamic pressure thrust bearing comprises: a thrust disc (10), one or more threaded grooves (101) being provided on the disc surface thereof, and the threaded grooves (101) being arranged along the circumferential direction of the disc surface; and a dynamic pressure bearing assembly (20), arranged coaxially with the thrust disc (10) and arranged opposite to the disc surface. When the dynamic pressure thrust bearing rotates at a high speed, the threaded grooves (101) drive air between the thrust disc (10) and the dynamic pressure bearing assembly (20) to flow to transfer heat, thereby facilitating improvement of temperature uniformity of the dynamic pressure thrust bearing, and also facilitating cooling and improvement of operation reliability.
