1. Overview of the global slip ring industry
1.1 Definition and working principle of slip ring
Slip ring, as a key electromechanical device to achieve power and signal transmission between fixed and rotating parts, is also called conductive slip ring, collector ring, etc. Its basic working principle is to build a stable electrical connection between relatively rotating parts through the sliding contact between brushes and conductive rings. When the rotating part of the equipment is running, the brush slides on the surface of the conductive ring, thereby ensuring that the current and various signals (such as data signals, control signals) can be transmitted uninterruptedly to ensure the normal operation of the equipment. For example, in a wind turbine, the slip ring transmits the electric energy converted from wind energy captured by the rotating blades to the power grid stably; on the rotating workbench on the industrial automation production line, the slip ring ensures the continuous transmission of control signals and power supply, so that the workbench can operate accurately.
1.2 Main types of slip rings
Classification by transmission signal type
Power slip ring: mainly undertakes power transmission tasks, commonly seen in equipment that requires high-power power supply, such as industrial cranes, port loading and unloading equipment, etc., can transmit high voltage and high current, and meet the strong power support required for equipment operation.
Signal slip ring: Focuses on transmitting various data signals, such as encoder signals, sensor signals, video signals, etc. It is widely used in medical imaging equipment, security monitoring pan-tilt and other equipment with extremely high requirements for signal accuracy and stability, ensuring accurate and fast data transmission without signal distortion or loss.
Combination slip ring: It integrates power transmission and signal transmission functions, and can simultaneously meet the equipment's needs for power and multiple signal transmission. It plays an important role in scenarios such as aerospace equipment and complex industrial automation production lines, reducing the complexity of internal wiring of equipment and improving system integration.
Classification by structural form
Disc slip ring: It has a flat disc structure and is small and compact. It is suitable for equipment with limited installation space, such as some small automation equipment, instruments, etc. Its compact design facilitates the realization of rotational transmission functions in a small space.
Cap slip ring: It looks like a hat and is usually installed at the end of the rotating shaft. It is easy to integrate into the rotating parts of the equipment. It is more common in equipment such as camera pan-tilts and small robot joints, providing a simple rotation connection solution for the equipment.
Through hole slip ring: It has a through hole in the center, allowing the rotating shaft to pass directly through. It is particularly suitable for applications that require full-scale continuous rotation around the axis and the shaft needs to be through, such as turntables, centrifuges and other equipment, to ensure that power and signal transmission are not affected during the rotation of the shaft.
1.3 Development History and Current Situation of Slip Ring Industry
The development of slip ring technology has undergone a long evolutionary process. Early slip rings had a simple structure and limited performance. The contact reliability between the brush and the conductive ring was poor, and the transmission efficiency was low. They could only meet some simple equipment applications with low transmission requirements. With the rapid development of materials science, manufacturing technology and electronic technology, modern slip rings have achieved a qualitative leap in performance. The application of new conductive materials, such as highly conductive and wear-resistant alloy materials, has significantly improved the service life and transmission performance of conductive rings and brushes; advanced manufacturing processes, such as precision machining technology, have greatly improved the manufacturing accuracy of slip rings, reduced contact resistance, and improved the stability and reliability of signal transmission.
At present, the global slip ring market is showing a trend of sustained growth. According to data from market research institutions, the global slip ring market size will reach 497 million yuan in 2023. With the acceleration of industrial automation and intelligentization, and the vigorous development of emerging industries such as new energy and smart security, it is estimated that by 2029, the global slip ring market size will grow to 607 million yuan, with an average annual compound growth rate of approximately 3.09%. From the perspective of regional distribution, the Asia-Pacific region has become the world's largest slip ring market, accounting for a large proportion of the global market share, thanks to its huge manufacturing base, rapidly developing industrial automation level and growing demand for emerging industries.
