Degassing disc for gas turbine lubricant box

The invention provides a degassing disc for a gas turbine lubricant box, belongs to the field of power device oil supply, and particularly relates to the degassing disc for the gas turbine lubricant box. The degassing disc comprises a degassing disc body, a step, a slope and an oil drain hole. The degassing disc body is horizontally arranged at the position, lower than a system oil return port, ofthe inner wall of an oil tank and used for bearing system return oil. The step is vertically arranged on the side, away from the oil return port, of the degassing disc body, and the bottom of the step is connected with the degassing disc body. The top end of the slope is connected with the top of the step, and the tail end of the slope penetrates into the oil tank. The oil drain hole is formed inthe degassing disc body, impact potential energy generated when the return oil falls into the oil tank can be obviously reduced, and air mixed into lubricant can be reduced. In addition, the step isdesigned on the degassing d
