In modern industry and high-tech equipment, the Slip Ring plays an indispensable role. As the "multi-functional link" between rotating and static components, the Slip Ring breaks through traditional cable technology limit in the process of its rotating operation, ensuring the seamless link between the energy and the information. And, its performance characteristics directly determine upper limit of overall motor system. The followings are the main features:
First, excellent electric transmission
The first mission of the Slip Ring acts as the bodyguard for stable transmission for the current and the signal. In the field of its contact resistance, high-performance slip ring, through the advanced design of precious-metal alloy brush and its conductive ring, can realize the contact resistances between the lowest static and its dynamic for the purpose of ensuring the lower losses and heating in the process of transmitting large current. Moreover, for complex medium transmission such as high-frequent signal, fiber optic and radio frequency, modern slip ring can meet the requirements for an extreme insert loss and an excellent voltage standing wave ratio, which can effectively isolate electromagnetic interference in the process of high-speed rotation for the purpose of ensuring accurate non-loss transmission for the data and the image.
Second, high-tech mechanic and structural characteristics
Inside the structure, the Slip Ring integrates a serious of complex components, including precious bearing, insolated materials and elastic brush. In order to adapt space limit of different kinds of the equipment, the Slip Ring presents a highly structural compactedness and provide related solutions for extra-large pore size or customized microminiaturization. In the process of its mechanic operation, excellent slip ring can meet the requirements for extremely low startup and dynamic friction moment of force, which can realize a smooth operation and lower noise. Through special open frame structure design, it can also effectively solve heat dissipation in the process of large current transmission, ensuring a long period of mechanically structural operation.
Third, excellent environmental adaption and strong prevention capacity
Many Slip Ring can service under extremely harsh environments. For example, in the systems of ocean engineering, ship propulsion appliances or navigation aid, the Slip Ring must meet the requirements for high-level water and dust resistance (IP prevention) and "Three-Aspect prevention" against salt and spray, erosion and mycete within the temperature range from -55℃ to 120℃. In the fields of aerospace and nuclear submarine, the Slip Ring should also meet the requirements for vibration-free, shock resistance and even high-precision signal transmission in vacuum environment.
Four, extremely longer service life and high reliability
As a precious quick-wear part, the core performances for the Slip Ring are its abrasive resistance and its service period. Thanks to advanced fiber-brush technology, gold-to-gold multipoint contact technology and excellently imported carbon brush material application, modern slip ring can realize a hundred-million-time operation with maintenance-free. Meanwhile, in order to deal with its frequent repair and maintenance for offshore platform or large-scaled radar, the design of the Slip Ring usually reserves redundant channel after strict life-cycle-period test, ensuring a lasting operation stability under harsh environments.
In conclusion, the Slip Ring has already surpassed simple conductive component scope. Because it integrates material science, precious mechanical and microwave engineering, becoming the "rotating footstone" for major national equipment and high-end smart equipment.
