Abstract

The current diverter rings and bearing isolators serve to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One embodiment of the current diverter ring includes an inner body and an outer body configured to clamp at least one conductive segment between them. In the preferred embodiments of the current diverter ring, the conductive segments are positioned in radial channels. The outer body may be affixed to a shaft, a motor housing, a bearing isolator, or other structure. The bearing isolator may incorporate a retention chamber for holding conductive segments within the stator of the bearing isolator, or the bearing isolator may be fashioned with a receptor groove into which a current diverter ring may be mounted.

Claims19

Dependent claims

A multi-ring current diverter ring comprising:

a. a retainer comprising:
i. a retainer base extending in the axial direction, wherein an outer surface of said retainer base is defined as a retainer radial exterior surface;
ii. a first annular groove formed on an inner surface of said retainer base;
iii. a retainer wall extending radially inward from said retainer base;
and
iv. a second annular groove formed on said inner surface of said retainer base;
b. a first ring comprising:
i. a radial channel fashioned in an interior axial surface of said first ring, wherein said interior axial surface of said first ring abuts said retainer wall;
ii. a radial ring exterior surface abutting said first annular groove;
and
iii. an exterior axial surface opposite said retainer wall;
c. a second ring comprising:
i. a radial channel fashioned in an interior axial surface of said second ring, wherein said interior axial surface of said second ring abuts said exterior axial surface of said first ring;
ii. a radial ring exterior surface abutting said second annular groove;
and
iii. an exterior axial surface opposite said first ring.
d. a conductive segment, wherein said conductive segment is positioned in said radial channel of said first ring.
