The invention relates to a multipoint radial jetting oil supply nozzle for a high-speed and heavy-load bevel gear. A hollow oil chamber, an oil inlet and oil jetting holes are formed in the nozzle. The hollow oil chamber communicates with the oil inlet and the oil jetting holes. A circumferential locating boss is formed at the end of the oil supply nozzle. The oil jetting holes comprise the first oil jetting hole, the second oil jetting hole and the third oil jetting hole. The three oil jetting holes are all formed in the end of the oil supply nozzle, and an independent included angle is formed between each of the three oil jetting holes and the central axis. An upper limit value of the oil supply amount exists for transmission of any gear. When the oil supply amount exceeds the upper limit value, no cooling effect can be achieved for the gear. The upper limit value is called as the valid oil supply amount, and the exceeding part is the invalid oil supply amount. By means of the multipoint radial jetting oil
