What is a slip ring made of?

The body of the slip ring is composed of many parts, including shaft assembly, brush assembly, bearing, housing, various interfaces, etc. According to different application fields, the design of components is different. However, everything should be properly prioritized and clearly defined. Similarly, the slip ring is the same. The shaft assembly (stator) and brush assembly (rotor) of the ring are the two most important components of the slip ring, namely, the contact of the slip ring, which is the most critical core component affecting its performance.

The shaft body of the slip ring is machined from an aluminum alloy or stainless steel, and then the shaft body is equipped with an electroplated super hard gold copper ring. A complete shaft body component is made through different processing processes. Some of them are precisely overlapped through the channel, and the number of overlapping paths is set according to the use requirements. Some are formed by integrated processing technology, and the processing methods are different according to different use requirements. The slip ring brush is a material lapped on the shaft body. It can be divided into many kinds, including single brush wire made of precious metal gold alloy material, brush bundle made of silver plating, graphite brush block, etc.

How do slip rings work?

The slip ring transfers energy and data between two components, mainly consisting of a group of metal rings and corresponding brush lines. The working principle of the slip ring is to make the metal ring contact with the wire. During this process, the brush part is stationary, the metal part rotates, the wire of the brush and the conductive ring contacts internally, and is electrically connected with the equipment on both sides of the slip ring. Therefore, one end of the wire and the stator of the slip ring are fixed, and the wire at one end and the rotor of the slip ring rotate together, which is equivalent to no winding.

What is the function of slip ring?

During the electrical design of the slip ring, when the mechanical part rotates 360 degrees, the electrical engineer will encounter the problem of wire winding. At this time, he needs an electrical rotary connector, commonly known as the electrical slip ring, to transmit the rotary connection of power and signal.

That is to say, the role of the slip ring is the electrical component responsible for connecting and transmitting energy and signals for the rotating body. According to the different transmission media, the slip ring can also be divided into electric slip ring, fluid slip ring, smooth ring, etc., which can also be collectively referred to as "rotary connection" or "rotary connection".

What are the applications of slip rings?

Slip rings are widely used. In modern high-end industrial equipment, there are many requirements for relative motion such as revolution and rotation to transmit different energy media (weak current signal, optical signal, air pressure, water pressure, etc.), so as to ensure that electrical appliances work normally when rotating. For example, among common medical equipment, amusement equipment, display equipment, intelligent cameras, revolving doors and other equipment, as well as uncommon aerospace equipment, radar communication equipment, automatic processing equipment, smelting equipment, cable equipment, crystal furnaces, robots and other fields, slip rings are essential equipment elements.
