What is a slide ring?

SLIP CING is a device that allows the transfer of electric current or signal between the static source and a rotating object without using a physical cable connection between them. The arrangement of the slip ring reaches this connection with the conductive ring connected around the rotating component and the brush -charged brush or contact on the static component. This brush carries against the swivel ring and maintains a constant electrical contact with it while it remains static. Slip devices have different applications.

The current or signal transmission between rotating and stationery objects is the engineering puzzle, which is best solved by low friction and sliding contact between them. In applications involving rotor, such as applications found in generators and engines, it is the best way to achieve this, use a solid slide ring. It consists of a conductive ring, usually made of high -quality polished copper that runs around the rotor shaft. This ringThe IS insulated from the shaft and was involved in the rotor winding. It is located a brush charged with springs carrying electricity to maintain constant pressure on the ring during its rotary travel in this way by completing the circuit.

Brushes are usually made of conductive material such as carbon that is softer than the ring. This material is used to ensure that the brush, rather than the ring, first wears, because the brush is easier and cheaper when it wear. In applications that require low resistance, mercury can be used to replace carbon brushes. However, due to its toxicity, it may not be used in pharmaceutical or food industries where mercury contamination represents a health risk.

The use of the slip system is not limited to the passage of electric current. This transmission is also not limited to the static passage of the rotoring either; Current, signal or daThese can be transferred from a rotating component to a static element. As long as the surfaces of the brush and the ring are maintained clean and without corrosion and chips, the connection to the slip can be very "clean" with a minimum of sparking, interference with data and sound noise. The application of the slip ring includes a rotating signal or warning beacons, alternators, generators and engines with electric slip and use several patterns and materials for rings and contacts.
