Utilizing Rotary Joints in Electromechanical Systems: Signal Conduction in Moving Applications

Rotary joints, also known as rotary-electric joints, are key components in many electromechanical systems, where it is necessary to transmit electrical signals between moving parts. Due to their ability to continuously transmit signals and enable unlimited rotations in both directions, they are indispensable components in various applications, from industrial machinery to medical devices.

Division into Brushed and Brushless Rotary Joints

Rotary joints are mainly divided into two categories: brushed and brushless. Brushed joints, utilizing special brush and ring manufacturing technologies, are characterized by very high rotational speeds and long trouble-free operation times. They can reach speeds of up to 1000 rpm and withstand even up to 150 million revolutions, depending on the quality of materials used in production. Additionally, the possibility of gold or silver plating of rings and brushes positively influences the quality of the connection and the durability of the joint.

On the other hand, brushless joints utilize the latest technologies in conductivity, often using a small amount of mercury as a conductor. They are made of high-quality insulating materials and seals, ensuring reliability in harsh environmental conditions. Their housing, made of aluminum or stainless steel, guarantees durability and resistance to working conditions.

Hybrid Rotary Joints

Modern industrial needs require increasingly advanced solutions. Therefore, hybrid rotary joints, which allow simultaneous transmission of power and various electrical and pneumatic signals, are increasingly used. Designed to meet specific customer requirements, these joints are the perfect solution for advanced applications, providing both versatility and reliability.

Signal Transmission Possibilities

With hybrid rotary joints, we can transmit various signals, including:
• Power up to 300A per contact,
• Profibus,
• Ethernet at various speeds (10M/100M/1000M GBit),
• RF signals up to 3 GHz,
• RS 232 and RS 485 serial interfaces,
• Fiber optic transmission,
• HD-SDI quality television signals,
• Coolants, water, steam, gas, air, and oil,
• Temperature measurement using PT 100 sensor.

With these capabilities, rotary joints become key elements in advanced industrial systems, ensuring reliable communication even in the most demanding conditions.

Summary

Rotary joints are essential components in electromechanical systems, enabling smooth transmission of electrical signals even in moving applications. Thanks to various technologies and capabilities, these joints provide reliability, durability, and flexibility in adapting to individual customer needs.
