Beschreibung
Zusammenfassung:	The invention belongs to the technical field of gas turbines, and particularly relates to a bearing oil baffle assembly of a gas turbine shaft, which comprises a right baffle ring, a middle baffle ring and a left baffle ring, the middle baffle ring is fixed on the left side of the right baffle ring, and an oil intercepting cavity is formed between the middle baffle ring and the right baffle ring; the left baffle ring is fixed to the left side of the middle baffle ring, and a pressurizing air cavity is formed between the left baffle ring and the middle baffle ring. Sealing rings are embedded in the inner ring sides of the right baffle ring, the middle baffle ring and the left baffle ring, and the inner ring sides of the sealing rings are attached to the turbine shaft to form sealing; pressure differences are formed between the pressurizing air cavity and the air cavity, between the pressurizing air cavity and the oil intercepting cavity and between the oil intercepting cavity and the lubricating oil cavity.
