Slip rings for electrical machines

The invention relates to a slip ring body for electrical machines, in particular for high-speed alternators lower power, with slip rings made of non-metallic materials.

Slip ring bodies are known in which the current supply and discharge to the slip rings made of non-metallic materials is accomplished by pressure, adhesive or cutting contact arrangements or, in the case of additional metallization, by conventional soldering or welding processes.
For example, it is known to screw such a slip ring onto a metallic threaded bushing.,
so that the threads cut into the material of the slip ring and bring about good contact. However, this contact has the disadvantage that as a result

the use of a metallic threaded bushing provides additional insulation to the shaft of the electrical machine erfcxderliah which is an additional Ieolier & auteil in the Öesamtkonstiaiiction des SoleifringkiJiper presupposes "

* So it is: a sole if ring body is proposed worlt # n »in which the 3tronu supply and discharge is also possible. the grinding made of non-metallic materials in which it quietly happens that round or band-shaped anchoring elements are inserted into prefabricated holes - the slots in the slip rings, the surfaces of which are provided with pointed elevations, which are then in the '7andungön dei · holes; ά $ χ · Sciilitza e.uis; anöideü uud bring about the right- speaking contact «

A part of this power supply and discharge is the unconditional requirement of holes or slots in the Slip rings which, for technological and economic reasons, are used in the mass production of slip rings of smaller dimensions, mostly in the extrusion process are made, not given 1st «

The purpose of the invention is to eliminate known status of the SteoJtnik under Jaesonöerer
