Abstract

PURPOSE: To obtain a sliding bearing adapted to maintain a constant rotational accuracy for a rotation shaft even if the load on the rotation shaft is changed by providing a plurality of wedge-shaped spaces to be gradually narrowed along the rotational wise of the rotation shaft between a wedge-shaped separation type bearing and the rotation shaft.
CONSTITUTION: A bearing metal 2 of two divided pieces is contained inside a casing 3. The inner surface 2b of this bearing metal 2 is shaped to come gradually closer to the periphery of a rotation shaft 1 along the rotational wise of the rotation shaft 1. That is, the shaft metal 2 is shaped like a wedge, and wedge-shaped gaps are provided between the rotation shaft 1 and the bearing metal 2. These gaps are filled with lubricating oil 4. In this construction, when the rotation shaft 1 is rotated as an arrow show, the lubricating oil is brought into narrower parts of the above-written wedge-shaped gaps because of its viscosity to generate a dynamic pressure, which helps to bear the rotation shaft 1 in a floating state against the bearing metal 2.
