JOURNAL BEARING
First Claim
1. A journal bearing for mounting a gear component thereon, the journal bearing comprising:
- a cylindrical body comprising;
two recessed portions defined on the cylindrical body;
a primary passage extending longitudinally through the cylindrical body; and
two secondary passages radially extending from the primary passage to the recessed portions, wherein an angle of the two secondary passages with respect to a horizontal plane of the journal bearing is based on at least one of the following;
magnitude and direction of a pre-determined bearing load;
rotational speed of the gear component;
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.

Abstract
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.

16. A method of designing a journal bearing to mount a gear component thereon, the method comprising:
-
defining a primary passage longitudinally through a cylindrical body; defining two secondary passages radially from the primary passage, wherein an angle of the two secondary passages with respect to a horizontal plane of the journal bearing is determined based on at least one of the following; magnitude and direction of a pre-determined bearing load; rotational speed of the gear component; 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; and defining two recessed portions on the cylindrical body such that the recessed portions are located adjacent to the secondary passages. - View Dependent Claims (17, 18, 19, 20)
