Rotating important part of the slip ring is usually installed on the machine, operate slip ring, brush with the ring through the relative sliding between the transmission signal, but as the growth of the running time, its produce powder can make the conductive ring and brush contact resistance increases, thus affecting the signal transmission and service life, so in order to prolong its service life and machine uptime, guarantee slip ring in vibration impact and high-speed rotating under the condition of normal work, requires a reasonable choice of matching slip ring manufacturer conductive slip ring and brush plating material, so the slip ring material selection is mainly divided into the material selection of conductive ring and brush the choice of materials.

 

First conductive ring material choice, because the work of the slip ring operation principle, so the material selection of conductive ring to match the brush material, at the same time, the performance of the conductive ring material directly affects the contact reliability and performance of slip ring, CENO at choice when considering the working conditions of the product and the performance of the selected material whether meet the requirements and the length of life, often conductive ring of material can be divided into two kinds, precious metals and their alloys, and metal and its alloy electroplating, plating metals can be divided into single metal plating, metal composite plating and alloy plating three.

 

Then is the choice of brush material, the material that requires the brush has enough to go to strength, good elasticity and conductivity, and not easy oxidation.CENO selected based on the working characteristics of the slip ring and usually use either pure gold or silver as the coating for the contact. However, both materials have their own advantages and disadvantages in processing, which are not discussed here.

 

Due to the special working environment of slip ring, materials with low resistivity, large elasticity and small elastic delay, high chemical stability, high electrical erosion resistance, high corrosion resistance and good processing performance are usually selected for the selection of two parts of slip ring.
