The invention provides a novel oil-cooled generator rotor component cooling oil circuit structure which comprises a generator hollow shaft, a rotor core, an excitation winding, V-shaped insulation paper, a V-shaped insulation support and a shunt slot wedge. The rotor iron core is in interference fit with the hollow shaft, V-shaped insulation paper and a V-shaped insulation support are arranged between the excitation winding and the rotor iron core, and the side face of the excitation winding, the V-shaped insulation paper and the V-shaped insulation support jointly form an oil guide way. And a shunting slot wedge is arranged between the excitation winding and the rotor iron core yoke part. According to the invention, cooling of the pole body, the pole shoe, the yoke part and the inner side surface of the winding of the rotor iron core is realized by designing the cooling oil path in the rotor iron core and designing the shunting slot wedge and the V-shaped insulating bracket, and the cooling effect of the rot
