Oil film bearing throttling nozzle for compensating on-way loss and structural design method

The invention discloses an oil film bearing throttling nozzle for compensating on-way loss and a structural design method, the nozzle is provided with an oil supply channel, the oil supply channel comprises a first oil supply hole and a second oil supply hole, the hole diameter of the first oil supply hole is larger than that of the second oil supply hole, and the nozzle can evenly distribute lubricating oil into an oil film bearing according to requirements through small hole throttling. In the structural design method, the near-end port is determined based on the lubrication station, then the aperture and length of the nozzle connected to the near-end port are determined according to the oil supply flow of the oil film bearing, and then the throttling aperture and length of the nozzle connected to the far-end port are determined according to the length difference in the length direction of the main oil supply pipeline. The throttling hole diameter of the nozzle far away from the lubricating station is conti
