What is a floating bearing?

    Full floating bearings and the rotor shaft and bearing shell there are gaps between, when the rotor shaft rotates at a high speed, with lubricating oil 0.25-0.4Mpa pressure with the two gap, the floating bearing in two layers of inner and outer oil film with the rotor shaft to rotate, but its speed but than the rotor shaft much lower, so that the bearing bearing hole and the rotor relative to the axis of the line and relative rate dropped significantly. Due to the double layer oil film, the double layer can be cooled, and the double layer damping can be generated. Therefore, the floating bearing has the advantages of high speed and light load, but at the same time, it is found that the floating bearing is very high to the lubricating oil. Must pay attention to the provisions of the filling of lubricating oil
