True-tilting pad (100) of journal bearing (300) has face (102) with border region (112) including engagement surface (114) and defining pocket (116) with longitudinal sidebars (121, 123), bottom (119), and abrupt step (120). The pad is pivotally supported by pivot (122) and can cooperate with one or more other pads and fluid (126) within housing (124) to hydrodynamically and mechanically support the shaft. The pocket (116) hydrodynamically increases pressure on the convex surface (111) of the shaft during rotation, and generates pressure effecting on the face (102) counteraction force about the pivot (122) and upstream relative to the rotation direction (108) in order to counteract spragging force. Method of journal bearing relatively dimensions the pocket. |
