Publication number: 20180175695Abstract: A bearing isolator and explosion-proof current diverting device may be configured to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One aspect of an explosion-proof current diverter ring may include a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft. A conductive assembly may be positioned in a radial bore formed in the stator such that the conductive assembly contacts the rotor to conduct electricity from the shaft to the housing through the explosion-proof current diverting device. The explosion-proof current diverting device may be configured to define a flame path to achieve various explosion-proof certifications.Type: ApplicationFiled: November 21, 2017Publication date: June 21, 2018Inventors: Robert A.

Patent number: 9614339Abstract: 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 is substantially arc shaped with a plurality of radial channels extending there through. A conductive assembly may be positioned in each radial channel such that a contact portion of the conductive assembly is positioned adjacent a shaft passing through the center of the current diverter ring. The arc-shaped body may be particularly useful during installation over certain existing shafts.Type: GrantFiled: April 28, 2015Date of Patent: April 4, 2017Assignee: Inpro/Seal, LLCInventors: Dwight A.

Publication number: 20170077663Abstract: 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.Type: ApplicationFiled: November 14, 2016Publication date: March 16, 2017Inventors: David C.

Publication number: 20150229085Abstract: The current diverter rings (CDRs), captured CDRs, bearing isolators, and explosion-proof CDRs 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 explosion-proof current diverter ring includes a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft may be encompassed by stator and a cap, which cap may be secured directly to the stator or the housing. A conductive assembly may be positioned in a radial channel formed in the stator such that the conductive assembly contacts the shaft to conduct electricity from the shaft to the housing. Another embodiment of an explosion-proof current diverter ring does not require a rotor. The explosion-proof current diverter ring may be configured to define a flame path to achieve various explosion-proof certifications.Type: ApplicationFiled: April 22, 2015Publication date: August 13, 2015Inventors: Neil F.
