JSB Type One-Shell Axially Mounted Snake Spring Coupling

The JSB Type Snake Spring Coupling is a high-performance flexible coupling featuring a single-piece outer shell and axially assembled serpentine spring elements. It is specially engineered to transmit torque smoothly while absorbing shock, damping vibration, and compensating for misalignment between connected shafts. Its compact design and ease of installation make it a preferred solution in demanding industrial applications.

This coupling uses a special serpentine spring (also called a "snake spring") which engages precisely machined teeth on two hubs housed within a rigid outer shell. The spring’s flexibility allows for minor shaft misalignments while also providing excellent torque transmission performance and vibration isolation.

Key Features:

• Axial assembly design
  The coupling is assembled by inserting the spring axially, allowing for quicker installation and easier maintenance, especially in confined spaces.

• Compact one-piece shell structure
  The single outer shell provides strong protection for the spring and internal components, improving durability and alignment integrity.

• Serpentine spring for smooth torque transmission
  The spring allows for progressive load transfer, which helps to absorb shock and reduce torsional vibration during operation.

• Good misalignment compensation
  Capable of handling angular, axial, and small radial misalignments without compromising transmission efficiency.

• Low noise and vibration
  Ideal for applications where quiet operation and reduced mechanical stress are required.

• Maintenance-friendly
  No lubrication is needed, and parts can be easily replaced without disassembling connected equipment.

Typical Applications:

The JSB Snake Spring Coupling is widely used in:

• Gearboxes and reducers

• Conveyors and lifting systems

• Pumps and compressors

• Metallurgy and mining machinery

• Fans and ventilation systems

• General rotating machinery requiring high-reliability power transmission

Operating Conditions:

• Operating temperature: –30°C to +80°C

• Suitable for medium-speed, medium-torque applications

• Forward and reverse rotation compatible

• No lubrication required due to dry-flex operation

• Designed for horizontal installations (customizable for vertical or inclined arrangements)

The JSB Type One-Shell Axially Mounted Snake Spring Coupling offers a balanced combination of high torque transmission, flexible compensation, and reliable operation. Its efficient design and robust performance make it an excellent choice for industrial environments requiring both flexibility and precision in drive systems.
