DEVICE FOR REMOVAL OF STATIC ELECTRICITY CHARGES FROM ROTATING OBJECTS Russian patent published in 2025 - IPC H01R39/00 H05F3/02 

FIELD: electricity.

SUBSTANCE: invention relates to devices for removal of static electricity charges from rotating objects. Proposed device comprises housing with axle fitted therein. Rolling bearings are installed on the axle, on which two current-collecting discs rest, each of them with a damping, for example polyurethane, rim. Current-collecting discs are made of current-conducting material. Between the discs, a support element is installed and rigidly fixed to one of the discs by a clamp, which is a ring from a package of alternating layers of damping material and soft current-conducting material, laid in layers and forming a current-collecting surface in contact with the current-carrying object. Damping outer rim of the current-collecting discs has a recess made along circular arcs directed by the concave part one towards the other and forming, in the pressed state, a support surface in the form of an annular groove in contact with the current-carrying object. Current-collecting surface of the support element forms a surface which is single with the support surface of the annular groove of the rim of the current-collecting discs.

EFFECT: elimination of sparking and noise, which enables to use the device when working with flammable materials, as well as with rotating light, heavy and large-sized objects.
