Lubricating and cooling system for speed reducer of roller press

The invention discloses a roller press speed reducer lubricating and cooling system which comprises an oil separator and a first middle box body, lubricating and cooling oil enters the oil separator through a flange, and the oil separator is sequentially communicated with a first lubricating pipeline, a second lubricating pipeline, a third lubricating pipeline, a fourth lubricating pipeline, a fifth lubricating pipeline, a sixth lubricating pipeline and a seventh lubricating pipeline; the invention relates to the technical field of speed reducer lubrication. According to the lubricating and cooling system for the speed reducer of the roller press, special lubricating and cooling oil ducts are established for gear meshing and bearings, the lubricating and cooling effect of the speed reducer is improved, each lubricating part adopts a nozzle form, and a certain pressure difference exists inside and outside each nozzle, so that oil sprayed from the nozzles is almost in a straight line within a certain distance,
