A rolling bearing apparatus includes a rolling bearing, a seal, first and second machine elements and a bypass apparatus. The rolling bearing includes a concentrically arranged first bearing ring and second bearing ring, and rolling elements arranged radially between the first bearing ring and the second bearing ring. The seal is arranged radially between the first bearing ring and the second bearing ring, and the second bearing ring is installed in the first machine element. The bypass apparatus forms an electrical connection between the first machine element and the second machine element. The bypass apparatus includes an electrically conductive bypass line and a holder connected to the electrically conductive bypass line in an electrically conductive manner. The holder is fastened to the second bearing ring radially between the second bearing ring and the first machine element.

Rolling bearing apparatus

A discharge device for discharging an electrical charge and/or voltage from a rotor of an electric motor via a shaft from a first discharge partner to a second discharge partner, the discharge device including a support body device, wherein the support body device includes a connecting portion for electrical and mechanical connection to one of the discharge partners and expanding portions for expanding the connection of the support body device to the one of the discharge partners, wherein the expanding portions include the connecting portion.

Discharge device for discharging an electrical charge from a rotor of an electric motor

A grounding apparatus for an electrical drive assembly configured for conducting an electrical charge and/or voltage from a rotor of an electric motor via a shaft as a first grounding partner to a second grounding partner. The grounding apparatus has: a supporting body device with a connecting section for electrical and mechanical connection to one of the grounding partners, and a supporting section; a contacting device having a contacting section for electrical connection to the other of the grounding partners, the contacting device having an attachment section and being connected to the supporting section of the supporting body device via the attachment section. The grounding apparatus bridges an annular gap between one grounding partner and the other, and the grounding apparatus has at least one opening which forms or helps to form an air passage in the annular gap in an axial direction.
