Journal bearing

摘要

A journal bearing is provided for mounting a gear component thereon and for reducing vibrations from operation of the gear component. The journal bearing includes a cylindrical body having two recessed portions defined thereon. The journal bearing further includes a primary passage extending longitudinally through the cylindrical body, and two secondary passages radially extending from the primary passage to the recessed portions. An angle of the two secondary passages with respect to a horizontal plane of the journal bearing is based on at least one of a magnitude and direction of a pre-determined bearing load, a rotational speed of the gear component, a clearance between the journal bearing and the gear component, oil properties, wherein the oil is introduced between the journal bearing and the gear component, and one or more system stability parameters.
