Electrical Through Hole Slip Ring

Electrical Through Hole Slip Ring is a special electrical component designed for applications that require the transmission of electrical quantities such as current and signals during equipment rotation. It achieves electrical connection between rotating and fixed components through a conductive structure with a central hole, without affecting the rotational movement of the equipment. The through-hole Conductive Slip Ring has been widely used in multiple fields due to its unique structure and function.

2、 Characteristics

Central perforated design:

The significant feature of through-hole conductive Slip Rings is that they have one or more holes at the center, which allow the rotating parts of the equipment (such as shafts) to pass through while achieving electrical connections.

The size of the hole is usually customized according to application requirements, with common aperture ranges from a few millimeters to tens of millimeters. For example, some models of through-hole conductive Slip Rings have a hole diameter of up to 38mm or 50mm, meeting the requirements of large-diameter shafts.

Efficient electrical transmission:

The through-hole conductive slip ring adopts advanced conductive materials and structural design to ensure high efficiency and stability of electrical transmission during rotation.

Electrical contact resistance is usually extremely low, less than 1 milliohm, which ensures accurate transmission of signals and currents and reduces energy loss during transmission.

Multi channel transmission capability:

Through hole conductive slip rings can simultaneously transmit multiple currents and signals, meeting the needs of complex electrical systems.

The common number of transmission channels varies from 1 to 24, depending on the model and design of the slip ring. These channels can transmit the same or different currents and signals, providing flexible electrical connection solutions for devices.

Low torque, low loss:

The design of through-hole conductive slip rings optimizes the friction and wear between rotating and fixed components, reducing torque and losses during rotation.

This enables the slip ring to maintain stable electrical performance under high-speed rotation and long-term operation, extending its service life.

High reliability and long lifespan:

The through-hole conductive slip ring adopts high-quality materials and manufacturing processes, ensuring its high reliability and long service life.

Some models of slip rings can have a lifespan of hundreds of millions of revolutions under normal usage conditions, which greatly exceeds the lifespan of ordinary electrical connection components.

Maintenance free design:

The structural design of the through-hole conductive slip ring makes it maintenance free. Once installed, users do not need to regularly maintain or replace it.

This reduces the maintenance cost of the equipment and improves its reliability and stability.

This avoids damage to the cable due to twisting or wear during rotation, ensuring stable signal transmission.

Wind power generation:

In wind power generation systems, through-hole conductive slip rings are used to connect the electrical connections between the rotating and fixed components of the wind turbine.

This enables the wind turbine to maintain stable power transmission during rotation, improving power generation efficiency.

Filling and packaging machinery:

In filling and packaging machinery, through-hole conductive slip rings are used to connect electrical connections between rotating and fixed components.

This enables the machine to maintain stable electrical connections during rotation, achieving automated filling and packaging processes.

This enables the aircraft to maintain stable electrical connections during flight, ensuring the safety and reliability of the aircraft.

Medical equipment:

In medical equipment, through-hole conductive slip rings are used to connect electrical connections between rotating and fixed components.

This enables medical devices to maintain stable electrical connections during rotation, improving the reliability and accuracy of the equipment.

Other fields:

In addition to the above application scenarios, through-hole conductive slip rings are also widely used in fields such as robotics, automation equipment, testing equipment, etc.

In these fields, through-hole conductive slip rings provide stable electrical connections between the rotating and fixed components of equipment, ensuring the normal operation and reliability of the equipment.

4、 Maintenance methods

In order to ensure the long-term stable operation of through-hole conductive slip rings, the following maintenance measures need to be taken:

Regular inspection:

Regularly inspect the through-hole conductive slip ring, including electrical performance, structural integrity, and contact surface wear.

If any abnormal phenomena are found, such as severe wear on the contact surface or decreased electrical performance, they should be promptly treated or replaced.

Cleaning and maintenance:

Regularly clean the contact surface and surrounding environment of the through-hole conductive slip ring to remove impurities such as dust and oil.

Use specialized cleaning agents and tools for cleaning to avoid damage caused by corrosive substances or tools.

After cleaning, ensure that the surface of the slip ring is dry to avoid residual moisture causing corrosion or short circuits.

Lubrication and maintenance:

According to the usage of the equipment and the manufacturer's recommendations, regularly lubricate and maintain the through-hole conductive slip ring.

Use appropriate lubricants to ensure a moderate coefficient of friction between the contact surfaces, reducing wear and heat generation.

Attention should be paid to the stability and durability of lubricants in environments such as high temperature and high speed.

Avoid overload:

During use, avoid exceeding the rated current and voltage range of the through-hole conductive slip ring.

If high-power signals or electricity need to be transmitted, corresponding specifications and models of slip rings should be selected to ensure the normal operation and safety of the equipment.

Storage environment:

If the through-hole conductive slip ring is not used for a long time, it should be stored in a dry, ventilated, and non corrosive environment.

Avoid prolonged exposure to harsh environments such as high temperature, high humidity, or strong magnetic fields to prevent damage to the equipment.

Professional training:

Provide professional training for operators and maintenance personnel to understand the working principle, performance characteristics, and usage precautions of through-hole conductive slip rings.

Improve the skill level of operation and maintenance personnel to ensure the correct use and maintenance of equipment.

Recording and analysis:

Establish usage and maintenance records for through-hole conductive slip rings, including inspection time, cleaning frequency, lubrication status, etc.

Regularly analyze and summarize records to promptly identify potential issues and take corresponding measures.
