The utility model relates to a splashing differential pressure lubricating system of a speed-changing box. The splashing differential pressure lubricating system comprises a speed-changing box shell and a first lubricating oil channel which is formed in the top of the speed-changing box shell, wherein one end of the first lubricating oil channel is communicated with the inside of a first oil collection box, and the other end of the first lubricating oil channel is communicated with an internal oil circuit of an input shaft; a second lubricating oil channel is also formed in the speed-changing box shell, one end of the second lubricating oil channel is communicated with the top of a ball bearing on an output shaft, the other end of the second lubricating oil channel is communicated with the inside of a second oil collection box, and the side part of the second oil collection box is communicated with the side part of the first oil collection box through an oil collection channel. By adopting the splashing differential pressure lubricating system, the lubricating oil can be adequately collected through the oil collection device; moreover, each bearing can be lubricated through each lubricating oil channel, and the service life of the bearing can be prolonged.
