According to the type of slip ring, Jingpai slip ring can be divided into: cap type slip ring, hollow shaft type (over-hole) slip ring, separated slip ring, disk type slip ring, high frequency/fiber optic slip ring, high-current slip ring ...... and so on
1, ? Cap slip ring Features: monofilament gold alloy material, one-time bending molding, stability is relatively good, wear resistance is good, the shortcomings of the elasticity of some of the shortcomings; high life expectancy, small contact resistance, compatible with various types of data bus communication protocols, small rotating torque, smooth operation, high stability, compact structure, small size; Applications: monitoring, electrical test equipment, rotary table, robots, medical equipment, rotary table, exhibition/display equipment, instrumentation, LED, etc..
2.? Hollow shaft type (over-hole) slip ring Features: the use of brush hard and ring soft characteristics, brush wire to silver alloy into a bundle of brush wire-based, in order to better match the friction, the ring is also based on silver as the main material, silver has a very good lubrication, so that the design of the life of the higher, the disadvantage is that the ring is a large diameter, wear down the grinding will be more, because of the brush wire wear is a point, the ring wear is a whole circle; Advantages: easy to install, 360-degree continuous Rotary transmission of power and data signals, ultra-long life / maintenance-free, compatible with various types of data bus communication protocols, transmission of analog and data signals; Applications: robotics, radar antennas, medical equipment, wind power generation equipment, manufacturing and control equipment, exhibitions and display equipment, construction machinery, test equipment, packaging machinery, etc..
3.? Separate slip ring Features: composed of separated rotor and contact brush (brush has two kinds of brush wire, and graphite contact), of which the rotor part can be with through-hole for hydraulic channel, pneumatic channel or assembling drive shaft, can better match the space limitation and installation demand in customer's system, and can be used with pins/posts instead of wire contact; Advantages: stator and rotor are separated, transmission of current and signals, low contact resistance, Easy to install, use in narrow installation space; Applications: instrumentation and test equipment, aviation, military and medical fields, aerial photography, gimbals, military/civilian drones, etc.
4.? Disk slip ring Features: specially designed for vertical direction with height limitations of rotating equipment, its ring channel and contacts around a central hole contact, great savings in height space. Disk slip rings are also divided into two types: one-piece disk and separated disk. One-piece disk slip rings are available with solid and different sizes of overbore options; separated disk consists of separated rotor and stator, which can satisfy more stringent height requirements and can be installed independently according to the application environment.
5.? High-frequency slip rings (high-frequency rotary joints) Features: high-frequency rotary joints are used in continuously rotating devices to transmit high-frequency signals and high-rate signals between the fixed part and the rotating part, which can transmit analog signals and high-speed digital signals with a frequency of up to 500MHz - 50GHz; such slip rings have a compact structure, stable performance, good shielding effect, strong anti-jamming ability, and are easy to be integrated into other devices. Applications: radar antennas, military system devices, high-definition network video surveillance systems, satellite communication systems, medical engineering equipment, air traffic control, missile defense systems.
6.? Fiber optic slip ring Features: low transmission loss, high transmission bandwidth, large data capacity, ultra-long transmission distance, communication is completely free from the influence of electromagnetic interference, information security without leakage; Applications: fiber optic slip ring is mainly used in fiber optic communication system.
7.? High-current slip ring Features: the use of elastic materials and graphite alloy combination of good elasticity, a single brush through the current is large, contact-type brush wire is suitable for matching with the smooth type of ring channel, in the rotary movement is prone to wear and tear dust, the need for regular cleanup and maintenance, the cost is low, graphite alloy carbon brushes are not very suitable for transmitting data-type signals. Applications: wind power generation, ships, large engineering machinery and equipment, radar monitoring equipment.
