※ How big can the aperture of the large aperture slip ring be?

The conductive slip ring is an indispensable mechanical component in many modern industrial equipments. It can transmit power and signals between the 360° rotating equipment to avoid twisting and winding of the equipment during the rotating work. With the advancement and development of science and technology, the application range of automation equipment is more and more extensive, there is more and more large-scale mechanical equipment, and the requirements for conductive slip rings are correspondingly increased. In order to be applied to large-scale equipment, conductive rings are required. The aperture and current must be large enough to drive the device.


Such slip rings are called large-diameter conductive slip rings and are mainly used in entertainment facilities, such as Ferris wheels, merry-go-rounds, large turntables, and windmills. Since its establishment in 2004, Shenzhen JARCH Electromechanical Technology Co., Ltd. is a slip ring manufacturer that can independently develop, produce and sell. It has been specializing in conductive slip rings for more than ten years. Many new types of conductive slip rings have been developed, including large diameter slip rings. The diameter of JARCH slip ring has reached 500mm, 800mm, or even 1000mm, which can almost meet the inner diameter requirements of all large equipment. Gold alloy contact is used for the contact material of the slip ring, which can increase the service life. At the same time, it also improves the stability of the conductive slip ring in transmitting power and signals. In addition to the large diameter, JARCH slip ring can also customize the number of channels and the size of the current as needed.

※ How to use the slip ring?

The conductive slip ring is an electromechanical device that transmits power or signals from the rotating end of the equipment to the fixed end, avoiding the twisting and winding of the wires during the rotation process. Therefore, we must pay attention to some precautions when using conductive slip rings to avoid accidents.


First of all, when selecting the conductive slip ring, some corresponding parameters must be selected to match the mechanical parameters of the equipment; when the conductive slip ring is installed and disassembled, all power transmission must be turned off; the conductive slip ring is a precise electronic component When installing the slip ring, be sure to protect the conductive wire. Rough handling may damage the slip ring; the conductive slip ring cannot be used as load-bearing, and the transmission current cannot exceed the maximum transmission power of the conductive wire, otherwise the slip ring may be burned; When using a conductive slip ring, the operating environment of the conductive slip ring should also be considered, whether it needs to be waterproof, dustproof, explosion-proof or high temperature resistant to avoid accidents or even accidents; it is best to check the conductive slip ring every day before use. Whether there are hidden dangers, eliminate them in advance and prevent them from happening.


※ What should be paid attention to when using conductive slip rings?

Nowadays, the application fields of conductive slip rings are getting wider and wider, and they have penetrated into all walks of life. Almost every industry has its presence in equipment, and the importance of conductive slip rings is also growing. Therefore, the use of conductive slip rings Some precautions still need to be kept in mind.

The slip ring is a precision part, and it needs to be used with great care. Even if a slip ring with good performance is used, improper use will not achieve the expected performance effect, and the slip ring may be easily damaged. Therefore, pay attention to the following when using slip rings:

  • First, keep the slip ring and its surrounding environment clean. Even if the invisible smile dust enters the slip ring, it will increase the wear, vibration and noise of the slip ring;

  • Second, be careful when using and installing. Strong punching is not allowed, do not hit the slip ring directly with a hammer, and do not transmit pressure through the rolling elements;

  • Third, use appropriate and accurate installation tools, try to use special tools, and try to avoid the use of cloth and short fibers;

  • Finally, Prevent the slip ring from rusting When directly holding the slip ring by hand, fully wash the sweat on your hands before operation, apply good mineral oil, and pay attention to rust prevention in rainy season and summer.

Due to the diversity of working environments and conditions, under some special conditions, under light load conditions, the slip ring can obtain a longer life than traditional calculations.

These special operating conditions limit surface damage from contaminants when the rolling surfaces (tracks and rolling elements) are separated by a lubricant film. In fact, under ideal conditions, a so-called long slip ring life is possible.

The life of a rolling slip ring is determined by the number of revolutions (or operating time at a certain speed): a slip ring within this life should have initial fatigue damage (spalling or defects) on any slip ring or rolling element. However, whether it is laboratory test or actual use, it can be clearly seen that under the same working conditions, the appearance of the slip ring is the same, and the actual service life is very different.
