Explosion-proof current diverting device

摘要

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.

主权项

1. A bearing isolator comprising:
a. a stator configured for engagement with an equipment housing, wherein said stator is in electrical communication with said equipment housing, said stator comprising:
i. a main body;ii. an axial groove formed in said main body;iii. a radial bore extending from a radially exterior surface of said stator to said axial groove; b. a rotor configured for engagement with a shaft extending from and rotatable with respect to said equipment housing, wherein said rotor is in electrical communication with said shaft, said rotor comprising:
i. a main body;ii. an axial projection extending from said main body of said rotor and into said radial bore of said stator, wherein said axial projection is formed with a radially exterior surface; and, c. a conductive assembly positioned in said radial bore, wherein said conductive assembly is in electrical communication with said stator, and wherein a contact portion of said conductive assembly extends radially inward and physically contacts said radially exterior surface of said axial projection of said rotor.
