Title:
TILTING PAD JOURNAL BEARING AND ROTARY MACHINE USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/163162
Kind Code:
A1
Abstract:
This tilting pad journal bearing is configured so that the opening of an oil supply hole for supplying lubricating oil to the sliding section of a bearing pad can be set at different circumferential positions relative to the bearing pad depending on the position of the bearing pad. For example, in a bearing pad (2a) below a rotating shaft (1) which supports the load of the rotating shaft, the circumferential position of the opening (7a) of an oil supply hole (8a) relative to the bearing pad (2a) is set on the upstream side, in the direction of rotation of the rotating shaft (1), of the space (10) between pads, or, for example, in a bearing pad (2d) located above the rotating shaft (1) and on the side opposite the side which supports the load of the rotating shaft, the circumferential position of the opening (7d) of an oil supply hole (8d) relative to the bearing pad (2d) is set on the downstream side, in the direction of rotation of the rotating shaft (1), of the space (10) between pads.
