brushes Explanation: A slip ring consists of a stationary graphite or metal contact (brush) which rubs on the outside diameter of a rotating metal ring. As the metal ring turns, the electric current or signal is conducted through the stationary brush to the metal ring making the connection. Additional ring-brush assemblies are stacked along the rotating axis for more electrical circuits.

rotating surface Explanation: Typically, a slip ring consists of a stationary graphite or metal contact (brush) which rubs on the outside diameter of a rotating metal ring. As the metal ring turns, the electric current or signal is conducted through the stationary brush to the metal ring making the connection. Additional ring/brush assemblies are stacked along the rotating axis if more than one electrical circuit is needed. Either the brushes or the rings are stationary and the other component rotates.[1][2] This simple design has been used for decades as a rudimentary method of passing current into a rotating device. https://en.wikipedia.org/wiki/Slip_ring According to the above explanation, either the brush or the metal ring could be stationary or rotating, therefore I would go with "rotating surface", especially since the German term does not specify that either. However, since there is mention of score marks and striations on the surface, I would tend to think that the author is talking about the rotating metal ring. |

slip ring surface Explanation: Is, I think, the easiest solution. This is about checking surface wear (mechanical or electrical sliding wear) on the metal "bands" of slip rings caused by contact with the brushes. The actual electrical contact strip to the individual brushes is called the slip ring. (it's a ring, and it "slips" under the brushes when it rotates) For example: Overall appearance of the slip ring surface (could be surfaces with multiple slip rings) Slip ring surface with distinct streaks and banding The URL is to an article about wear on slip rings -------------------------------------------------- Note added at 5 hrs (2018-10-27 13:34:47 GMT) -------------------------------------------------- Damage can be caused by debris between the brushes and rings or uneven contact (mechanical wear) or by effects such as arcing (electrical wear) -------------------------------------------------- Note added at 5 hrs (2018-10-27 14:01:49 GMT) -------------------------------------------------- http://tinyurl.com/yc27ngm9 There's a nice diagram on page 3 of this PDF that shows the locations of rings and the brushes and describes the various parts. -------------------------------------------------- Note added at 5 hrs (2018-10-27 14:07:36 GMT) -------------------------------------------------- The PDF (page 2) also shows a drawing of a "separate brush block and slip ring assembly" showing the rings that would be inspected for wear. -------------------------------------------------- Note added at 5 hrs (2018-10-27 14:11:27 GMT) -------------------------------------------------- In electric motors, the ring is also known as a "conductor ring" https://www.arslipring.com/technical-article/generator-slip-ring-wear.html |
