Our Advantages

Electromagnetic design
Air gap between the stator and rotor core is smaller, therefore, our SG series generators have higher efficiency, compared with the products from other factories.

Excitation system
Excitation stator lamination is made by cold-rolled silicon steel sheet,with 1 or 2 high performance magnets, so the temperature rising of exciter is low, it will not lose excitation. Excitation start faster, easy to build pressure.Normally , when speed reach 600-700 rpm/min ,it is able to built pressure.

Mechanical Design
The biggest improvement is that, between driven disk and shaft,we adopts interference fit ,instead of key connection. Our advantage is that the process is more simple, the size is more precise,connection is more reliable.

Materials Used in Manufacturing Disc Couplings

Disc couplings are typically constructed using a combination of high-quality materials that contribute to their durability, strength, and performance. Some commonly used materials include:

  • Stainless Steel: Stainless steel is a popular choice due to its corrosion resistance and high strength-to-weight ratio. It ensures longevity and can withstand harsh environments.
  • Aluminum: Aluminum is known for its lightweight properties and is often used in applications where weight reduction is essential while maintaining reasonable strength.
  • Steel: Carbon or alloy steel is chosen for its robustness and ability to handle high torque loads and harsh operating conditions.
  • Bronze or Brass: These materials can be used in specific applications where electrical conductivity is a concern, or when friction and wear properties are important.

The selection of materials depends on factors such as the coupling’s intended application, torque requirements, environmental conditions, and the desired balance between strength, weight, and resistance to wear and corrosion.

Suitability of Disc Couplings for High-Speed Rotation and Critical Alignment

Disc couplings are well-suited for applications involving high-speed rotation and critical alignment due to their unique design and performance characteristics:

  • High-Speed Rotation: Disc couplings can handle high rotational speeds while maintaining their balance and integrity. Their lightweight and compact design minimize the effects of centrifugal forces, making them suitable for high-speed applications.
  • Critical Alignment: Disc couplings offer excellent flexibility and angular misalignment compensation. They can accommodate axial, radial, and angular misalignments, making them suitable for applications where maintaining precise alignment is crucial.
  • Torsional Stiffness: Disc couplings can provide a balance between flexibility and torsional stiffness, allowing them to transmit torque accurately even in critical alignment scenarios.
  • High Torque Capacity: Many disc couplings are designed to handle high torque loads, making them suitable for applications with demanding torque requirements.
  • Resonance Damping: The flexible nature of disc couplings can help dampen vibrations and reduce the risk of resonance, which is important in high-speed applications.

When selecting a disc coupling for high-speed rotation and critical alignment, it’s essential to consider factors such as torque requirements, speed range, misalignment compensation, space limitations, and dynamic behavior to ensure optimal performance and reliability in the specific application.

Disc Couplings: Function and Application in Mechanical Systems

A disc coupling is a type of flexible coupling used in mechanical systems to connect two shafts while allowing for angular misalignment, axial movement, and some degree of torsional flexibility. It consists of two hubs with flexible metallic discs, known as diaphragms, positioned between them.

Disc couplings are commonly utilized in various industrial applications where precise power transmission, reliability, and flexibility are essential. Some key features and applications of disc couplings include:

  • High Torque Transmission: Disc couplings are designed to transmit high torque loads between shafts while maintaining shaft alignment. The flexible diaphragms can accommodate misalignments and prevent torque overloads on connected equipment.
  • Angular Misalignment Compensation: The design of disc couplings allows them to handle angular misalignment between shafts, which can occur due to manufacturing tolerances or dynamic conditions.
  • Axial Movement Absorption: Disc couplings can absorb limited axial movement along the shaft axis without transferring excessive forces to the connected components.
  • Torsional Flexibility: The metallic diaphragms of disc couplings offer torsional flexibility, enabling them to dampen vibrations and shock loads. This helps protect connected equipment from damage and increases overall system reliability.
  • Precision Machinery: Disc couplings are often employed in precision machinery and equipment, such as CNC machines, robotics, pumps, compressors, and servo systems. These applications require accurate motion control and reliable power transmission.
  • High-Speed Applications: Due to their balanced design and ability to maintain precise alignment, disc couplings are suitable for high-speed applications where even a small misalignment can lead to vibration and wear.

The ability of disc couplings to provide both flexibility and precise torque transmission makes them a preferred choice in various industries, including manufacturing, aerospace, automotive, and more. Proper selection, installation, and maintenance of disc couplings contribute to improved machinery performance, reduced downtime, and extended component life.
