The present invention belongs to the technical field of electric drive axles for heavy-duty vehicles. Provided are an oil shield, and a lubricating structure for a high-speed bearing of an electric drive axle. The oil shield comprises an annular framework, wherein an inner circumferential surface of the annular framework is provided with a crescent soft plate; an outer circumferential surface of the crescent soft plate is fitted to the inner circumferential surface of the annular framework, and an inner circumferential surface of the crescent soft plate faces the center of the annular framework; and a fitting lip is provided in the middle of the inner circumferential surface of the crescent soft plate, and the fitting lip is arranged opposite the center of the annular framework. The beneficial effects of the present invention lie in that same can improve the oil surface level in an oil sump by means of the design of the crescent soft plate and the design of the fitting lip, thereby ensuring that there is a su
