Electrostatic discharging device
A discharging device for discharging electrostatic charges from a shaft includes a conductor arrangement having at least two bending elastic conductors arranged on a holder and made of a carbon-fiber arrangement. The holder has two holder legs arranged on a common pivot axis, each holder leg serving to accommodate a terminal section of a conductor. The holder legs are pivotable relative to each other to enable a holder angle (α) formed between the holder legs to be adjusted. The holder legs are lockable in a defined pivoted position.
1. A discharging device for discharging electrostatic charges from a shaft, said discharging device comprising:
a conductor arrangement having at least two bending-elastic conductors;
terminal sections for connecting the conductors to a grounding, each terminal section having a shaft contact section, the shaft contact sections forming a contact arrangement for making contact with two circumferential contact areas of a shaft circumference, the contact areas being arranged opposite each other in a shaft contact plane W, in such a manner that the shaft contact sections are arranged tangentially to the shaft circumference when they are in contact with the shaft circumference; and
a holder accommodating said terminal sections and on which said conductor arrangement is arranged, said holder being made of a carbon-fiber arrangement and running transverse to a shaft longitudinal axis, the holder having two holder legs arranged on a common pivot axis, each holder leg accommodating one of said terminal sections and the holder legs being pivotable against each other in order for a holder angle α formed between the holder legs to be adjusted and the holder legs being lockable in a defined pivoted position.
