たり、オイルミストの圧力を高くする必要がある。(Prior Art) In recent years, for bearings such as high-speed rotating bearings, lubricating oil is made into fine and light oil particles, and oil is sprayed at high speed on the rolling surface and sliding surface of a bearing from a nozzle together with compressed air for lubrication. Has been taken. In particular, in high-speed rotating bearings, the heat generated by the stirring resistance of the lubricating oil causes the temperature of the bearing to rise, so a very small amount of lubricating oil is continuously supplied and the wind that accompanies the high-speed rotation of the bearing breaks through. Atomizing energy is also required. Therefore, it is necessary to adjust the mixing ratio of the lubricating oil and the compressed air or to increase the pressure of the oil mist.
