Title: JOURNAL BEARING AND ROTARY MACHINE
Abstract:
This journal bearing is equipped with a first oil supply unit positioned upstream from and immediately in front of a first bearing pad, a second oil supply unit positioned at the location in the circumferential direction between the first bearing pad and a second bearing pad, and a pair of side plates mounted along the outer circumference of the rotor shaft to one end of the carrier ring in the axial direction and to the other end thereof. The journal bearing also has a gap for connecting the exterior and an interior bearing space which is enclosed by the pair of side plates between the outer-circumferential surface of the rotor shaft and the inner-circumferential surface of each of the side plates. The amount of lubricating oil discharged by the first oil supply unit is set so as to be greater than the amount of lubricating oil discharged by the second oil supply unit.
