Document Type and Number:
WIPO Patent Application WO/2023/051158
Kind Code:
A1
Abstract:
A gas bearing assembly, comprising a bearing seat (200), a bearing body (300), and a sealing ring (400). The bearing body is sleeved on a rotating shaft (100) and located in the bearing seat. The bearing body is provided with an annular gas cavity (310), the bearing body is provided with an annular sealing ring mounting groove, and an annular protrusion is formed between the sealing ring mounting groove and the annular gas cavity. The sealing ring is accommodated in the sealing ring mounting groove, and the sealing ring comprises at least one annular sealing unit. The sealing unit comprises an annular sealing outer layer (410) having at least one accommodating groove, and an annular elastic supporting portion (420) located in the accommodating groove. The elastic supporting portion expands the sealing outer layer by means of an elastic force, such that the sealing unit is tightly sealed with the bearing seat and the bearing body. By improving a gas bearing sealing structure, and in particular, improving a sealing ring structure, a sealing effect of the sealing ring is enhanced, and the sealing effect can be maintained for a long time even under a high-temperature working condition. A gas turbine having the gas bearing assembly is further comprised.
