1.What is a slip ring?
Slip ring is a mechanical transmission component, also called a rotary joint or swivel joint. Its main function is to realize the electrical and signal transmission of the machine equipment, so that the rotating parts can work normally during the continuous rotation. The slip ring consists of two parts: a fixed part and a rotating part. The fixed part is generally outside the machine equipment, and the rotating part is connected to the rotating shaft. There is a conductive material inside the slip ring, which realizes the transmission of current or signal through the conductive material.
2. Working principle of slip ring
The working principle of slip ring is to transmit current or signal through metal contact. Different slip ring manufacturers use different conductive materials, common ones are copper alloy, gold and silver alloy, etc. The conductive material is generally coated on the contact surface of the slip ring, and the current or signal is transmitted through the contact surface when the rotating part is connected to the fixed part. Since the slip ring is rotatable, it is generally necessary to use springs, springs and other mechanisms to ensure continuous pressure on the contact surface during rotation to ensure normal transmission.
3. Slip ring manufacturing materials
Since slip rings have a wide range of applications, different manufacturing materials will be selected for different application fields. Commonly used slip ring materials include pure copper, copper alloy, gold-silver alloy, stainless steel, etc. Among them, pure copper is suitable for low voltage and high current environments, and copper alloy is a more common slip ring material.
4. Application fields of slip rings
Slip rings are widely used in various mechanical equipment and manufacturing fields, among which the most common are engineering machinery, logistics conveying equipment, semiconductor equipment, equipment testing, etc. In engineering machinery, slip rings are mainly used for rotating equipment, such as tower cranes and cranes. In logistics conveying equipment, they are used to realize electrical transmission of rotating conveyor belts. In semiconductor manufacturing equipment, slip rings are used to transmit high-frequency current signals to realize the manufacturing of semiconductor chips.
In short, as a transmission device, slip ring plays a very important role. A deep understanding of the working principle and application field of slip ring is very helpful for engineers, manufacturers and users.
