Definitions
- the present invention is based on the problem of further developing a method for producing a multi-layer carbon brush, which consists of at least two electrically conductive functional layers and an insulating layer running between successive functional layers, in such a way that manufacturing simplification takes place, the possibility also being created, to design the insulating layer without problems for the area of application of the multi-layer carbon brush to be produced.
- Material properties such as porosity or friction values should also be easily adjustable.
- a problem-free individual design of the thicknesses of the functional layers is to be made possible without the need for complex processing measures.
- the problem is essentially solved in that the carbon material or the material containing this as filler and the electrically insulating material are introduced in powder form into a mold in the course of the layers of the multilayer carbon brush to be produced, then pressed and then heat-treated.
- the insulating material should be introduced into the mold with a respective layer height in such a way that the insulating layer in the finished multilayer carbon brush has a thickness d of preferably 100 ⁇ m ⁇ d ⁇ 500 ⁇ .
- the invention is characterized by a method for producing multilayer carbon brushes, each consisting of at least two electrically conductive functional layers made of carbon material and at least one insulating layer made of electrically insulating material, which runs between successive functional layers, by the method steps:
