Abstract
A shaft earthing ring for establishing an electrical potential connection between a rotating shaft and a housing of an electric motor comprises an electrically conductive earthing element which has a contact portion that contacts the shaft, and a metal support body fixed to the housing. The metal support body has at least one ventilation opening which allows ventilation of a housing interior while bypassing the earthing element.
Claims22
A shaft earthing ring for establishing an electrical potential connection between a rotating shaft and a housing of an electric motor, comprising:
- an electrically conductive earthing element which has a contact portion that is configured to contact a rotating shaft of an electric motor, and
- a metal support body configured to be fixed to a housing of the electric motor, wherein when the contact portion contacts the rotating shaft and the metal support body is fixed to the housing, an electrical potential connection is established between the rotating shaft and the housing,
- wherein the metal support body has at least one ventilation opening which allows ventilation of a housing interior of the electric motor while bypassing the electrically conductive earthing element.
