[Problem] To provide, as a main shaft bearing for a wind-powered electricity generation device, a composite sliding bearing that stably supports a radial load and an axial load with a compact construction, and has excellent maintainability. [Solution] A composite sliding bearing (3) is formed by means of: an inner ring (4), comprising two split rings (4a, 4b) which are divided at the center in the axial direction, with an inclined surface having a V-shaped cross section formed in the outer diameter surface thereof; bearing pads (5) arranged distributed on the inclined surface of the split rings (4a, 4b) along the outer diameter surface of the inner ring (4); and an outer ring (6), on the inner diameter surface of which is formed an umbrella-shaped inclined surface having a V-shaped cross section and corresponding to the outer diameter surface of the inner ring (4). When the bearing pads (5) are lubricated the inner diameter surface of the outer ring (6) slides on the sliding surface of the bearing pads, thereby supporting the radial load and the axial load applied to the bearing (3). |
