摘要： A journal bearing includes an oil supply nozzle, having an oil distribution part which extends in an axial direction of the rotation shaft and supplies lubricating oil, and a pad, provided at the rear side of the oil supply nozzle, in a rotational direction of the rotation shaft and supporting the rotation shaft rotatably. The inner periphery face of the pad, which opposes the outer periphery face of the rotation shaft, has an opening side face, in which the radial direction spacing between the inner periphery face and the outer periphery face of the rotation shaft becomes smaller, from the front end face of the pad, located at the front side in the rotational direction of the rotation shaft, toward the rear side in the rotational direction, and between the oil distribution part and the pad, the journal bearing has a bubble discharge path which discharges air bubbles.

摘要： A hydrodynamic bearing in the form of a flex pad bearing includes configurations structured to change a bearing characteristic. One form of the bearing includes a nonlinear back wall that includes a circular arc and a transition, where the back wall extends radially outward of a ligament. The bearing can include an opening for the deposit of a weighted mass, wherein the opening can threadingly receive a threaded weighted mass. In one form a sidewall that includes the back wall segment can have an average outer radius which determines a thickness of the flex pads.

摘要： A support of a bearing pad of a sliding bearing is provided. A bearing pad support connection is disclosed, including a bearing pad and a bearing pad support structure whereby the bearing pad is connected to a support structure by a ball joint. The bearing pad includes a ball head, and the support structure includes a ball socket. The bearing pad and the support structure are connected via a spring connection apply a force between the bearing pad and the support structure to force the ball head to rest movable in the ball socket.

摘要： Bearing adapters for use with truss foundations supporting mechanically balanced single-axis trackers. The bearing adapter joins the free ends of a pair of adjacent truss legs to form a rigid A-frame shaped foundation structure. A bearing is formed in an upper portion of the bearing adapter to allow a torque tube to be suspended from a pin in the bearing and to swing through an arc bounded by the bearing adapter. The bearing may have a catenoid shape to compensate for misalignment in multiple directions.

摘要： A journal bearing includes: a carrier ring; a plurality of bearing pads disposed on a radially inner side of a lower half region of the carrier ring; a pair of side plates disposed on both sides of the plurality of bearing pads with respect to an axial direction of the rotor shaft; and at least one oil-supply unit for supplying lubricant oil to the plurality of bearing pads. From among the at least one oil-supply unit, a first oil-supply unit disposed on a downstream side of a most downstream pad positioned most downstream of the plurality of bearing pads is configured to supply the lubricant oil toward a region below a corner portion of the most downstream pad, of a trailing edge surface of the most downstream pad, the corner portion being formed by an intersection between a pad surface of the most downstream pad and the trailing edge surface.
