Standard Through Hole Slip Ring

Standard Through Hole Slip Ring is a collective term for a series of conductive Slip Rings with a central hole. It is mainly used for transmitting precision signals, weak currents, high currents, and high voltages, while supporting the transmission of various media such as electricity, signals, and fluids. The through-hole slip ring solves the problem of energy and data transmission in rotating equipment through innovative hollow shaft design and precision contact system

2、 Characteristics

High space utilization:

Traditional Slip Rings require reserved external wiring space, while the hollow design of through-hole Slip Rings can be directly integrated into the equipment spindle, increasing space utilization by more than 50%.

Typical applications such as drone gimbal and surgical robot wrist joints benefit from this design, achieving a more compact and efficient layout.

Multi functional integration:

A single through-hole slip ring can simultaneously transmit power (such as three-phase AC and DC power), signals (such as RS485/CAN bus, optical fiber, thermocouple), and fluids (such as compressed air and cooling water, with optional rotary joints).

This multifunctional integration reduces the number of external adapters, lowers equipment failure rates, and lowers maintenance costs.

In terms of lifespan indicators, the standard product has a lifespan of ≥ 20 million revolutions per minute (calculated at 10 revolutions per minute, continuous operation for 3.8 years), ensuring the reliability of long-term operation.

Low torque, low loss:

The through-hole slip ring has low torque characteristics, making rotation smoother and reducing energy consumption and wear.

The low loss and maintenance free design extends the service life of the equipment and reduces maintenance costs.

Superior electrical performance:

The through-hole slip ring has low electrical noise characteristics, ensuring signal clarity and stability.

Stable transmission performance, suitable for high-precision and high-frequency signal transmission requirements.

High reliability:

Through rigorous testing such as MIL-STD-202G vibration test and 500G mechanical impact test, it meets military grade requirements.

It can maintain stable performance even in harsh environments and is suitable for various complex application scenarios.

3、 Application scenarios

Industrial automation:

In production lines that require high real-time and stability, such as robot control systems, through-hole slip rings can stably obtain external energy support (such as power batteries) or receive data commands from the host.

Intelligent logistics sorting equipment also relies on through-hole slip rings to achieve efficient operation.

medical apparatus and instruments:

From pacemakers to in vitro diagnostic instruments and various high-end therapeutic devices, through-hole slip rings complete complex electrical signal processing tasks.

The rise of remote medical service models has further promoted the application of through-hole slip rings in the field of medical devices.

Aerospace:

In satellite communication, deep space exploration and other projects, through-hole slip rings serve as a powerful "lifeline" guarantee to maintain the normal operation of various key businesses.

Its excellent adaptability and anti-interference characteristics meet the special requirements of the aerospace field.

Consumer Electronics:

In consumer electronics products such as smartphones and tablets, through-hole slip rings support various functions such as charging management, audio and video input and output.

With the continuous improvement of consumers' requirements for product performance, through-hole slip rings have broad application prospects in the field of consumer electronics.

4、 Maintenance methods

Safe power outage:

Before carrying out any cleaning or maintenance work, it is necessary to ensure that the equipment is completely powered off and all power and signal inputs are disconnected to prevent the risk of accidental short circuits or electric shocks.

Use specialized cleaning agents:

Choose a specialized cleaning agent suitable for slip rings to effectively remove light oil stains, carbon and fat pollutants formed by electric arcs, etc.

Use a spray to evenly spray the cleaning agent on the surface of the conductive ring. After cleaning, let the slip ring dry naturally for a period of time to ensure that the cleaning agent is completely volatilized.

Avoid damage:

During the cleaning process, avoid using overly strong solvents or brushes to prevent damage to the surface of the slip ring.

Regularly check the fasteners on the slip ring, such as bolts and nuts, to ensure they are securely tightened and avoid looseness and instability of the slip ring.

Lubricant maintenance:

Regularly inspect and replace lubricants according to the design and requirements of the slip ring.

Lubricate with slip ring specific lubricant to ensure even spraying and distribute lubricant evenly by rotating the stator frame.

Electrical connection inspection:

Regularly check the electrical connections of the slip ring to ensure its stability and reliability.

Pay attention to checking the contact of the wires and repair or replace damaged wires and connectors.

Environmental control:

Ensure that the working environment of the slip ring is clean and suitable.

Avoid prolonged exposure of the slip ring to damp, corrosive, or dusty environments to reduce damage and corrosion to the slip ring.

Professional maintenance:

It is recommended to hire professional maintenance personnel to disassemble and clean the slip ring to avoid damage caused by improper operation.

Develop a regular maintenance plan based on the working environment and frequency of use of the slip ring to ensure its long-term stable operation.
