Oscillation proof brushblock for sliprings

摘要

A slip ring assembly for the electrical connection of two rotating parts has at least a sliding track with V-grooves. At least two brushes of electrically conductive material are contacting the sliding track within the V-groove. The brushes are connected electrically with each other and mounted at different levels resulting in a different distance to the rotation axis of the sliding track. This results in an improved resistance against shock and vibrations.

1. A brush block for a sliding track, the brush block comprising:
a holder comprising a first carrier plate and a second carrier plate that is parallel to the first carrier plate; a first brush comprising an electrically conductive material; and a second brush comprising an electrically conductive material and electrically connected to the first brush, where the first brush is attached to the holder at a different distance from a rotating axis of the sliding track than the second brush,
the second brush is attached to the first carrier plate, and the first brush is attached to the second carrier plate, andthe second brush is electrically connected to the first carrier plate, andthe first brush is electrically connected to the first carrier plate and the second carrier plate.
