Characteristics of different types of slip ring structures

Regardless of the type of industrialproduct, structure is an important factor determining its performance, and forslip rings, the importance of structure cannot be denied. Different types of sliprings have different application scenarios. For example, the pancake slip ringdesigned with a flat structure is particularly suitable for installation inequipment with very small axial space. The slip ring designed with a separatedstructure can be applied to some platforms that require quick disassembly ortimely maintenance because of its convenient installation. The through-holetype slip ring can be quickly installed on the transmission shaft and otherrotating parts.

In addition to the installationadaptability brought by the external structure, the internal structure of theslip ring is also very important, which determines the service life of the slipring and is one of the important factors in electrical performance. As anestablished manufacturer in the field of slip ring manufacturing for nearly 30years, JINPAT has a sound verification process for slip ring structures. Sincethe establishment of the R&D center, JINPAT Laboratory has verified over athousand different slip ring structures and applied these verified slip ringstructures to standard and customized products.

Taking a small capsule slip ring as anexample, JINPAT has developed products on this series of slip rings, such aslong-life slip rings, high-speed slip rings, and IP68 high protection levelslip rings. The common feature between long-life slip rings and high-speed sliprings is that their lifespan exceeds one billion revolutions per minute. Thedifference is that low-speed slip rings with a hundred revolutions per minute canwork for many years, while the lifespan of high-speed products with a speed ofover 20000 revolutions per minute is determined by the startup time. Theinternal structure differences between these two products are very significant,and different structural designs give them unique electrical and mechanicalcharacteristics.

In addition to electric slip rings, thereare also some special types of slip rings with unique structural designs, suchas fiber optic slip rings and high-frequency slip rings. Due to thetransmission of optical signals, the fiber optic slip ring uses optocouplercomponents inside and does not require friction pairs. Therefore, its structureand electric slip ring have a large diameter, and the frictionless structure ofthe fiber optic slip ring also gives it a very long lifespan. After replacingthe high-speed bearing, its designed working speed can reach tens of thousandsof revolutions. Although high-frequency slip rings mainly transmit RF andhigh-definition video signals, they still belong to the category of electricslip rings. However, their internal structure is also different from ordinaryelectric slip rings. For example, the high-frequency sliding ring LPHF-05Dproduced by JINPAT for antenna bases adopts a multi contact structure, whichcan effectively reduce phase jitter and is suitable for high-capacity datatransmission without delay.
