JS GRID COUPLING is an advanced mechanical transmission connection device that achieves flexible connection between shafts through a unique snake shaped spring structure. Widely used in various industrial fields, it is highly praised for its excellent performance and reliability. Compared with traditional couplings, JS GRID COUPLINGs use snake shaped springs made of special alloy steel as elastic elements, and achieve a perfect balance between transmission efficiency and vibration reduction performance through precise mechanical processing and heat treatment processes.

The JS GRID COUPLING consists of the following key components:

• Serpentine spring element: made of high-strength alloy steel and subjected to special heat treatment process, it has excellent elasticity and fatigue life. The springs are arranged in a three-dimensional serpentine pattern and can absorb vibrations and impacts in multiple directions.
  

• Coupling hub: usually made of high-strength cast iron or alloy steel material, with an inner hole that matches the shaft, and a special tooth groove structure designed on the outer edge that matches the spring.
  

• Protective cover: protects the internal spring from external environmental influences and prevents lubricant leakage.
  

• Lubrication system: Some high-end models are equipped with automatic lubrication devices to ensure lubrication effectiveness during long-term operation.

When the driving shaft rotates, the serpentine spring is driven to deform through the teeth of the hub, and the spring then transmits power to the driven hub. The uniqueness of this design lies in:

• Three dimensional elastic deformation: Springs can not only deform radially and axially, but also achieve a certain degree of angular deflection, forming a true three-dimensional flexible connection.
  

• Progressive stiffness: As the torque increases, the deformation of the spring increases, and the stiffness also increases, forming a nonlinear torque deformation characteristic.
  

• Multi point contact stress distribution: The serpentine design distributes contact stress at multiple points, significantly reducing local stress concentration and extending service life.

Performance advantages and technical features

• Excellent vibration damping performance
  The vibration absorption capacity of JS GRID COUPLING is 40-60% higher than that of ordinary spring coupling, specifically manifested in:
  Can reduce the vibration amplitude of the transmission system by more than 70%
  Effectively suppress high-frequency vibration and instantaneous impact
  Reduce vibration damage to bearings and gearboxes

• Superb compensation capability
  Axial compensation: up to ± 5mm maximum
  Radial compensation: up to 1.5mm maximum
  Angle compensation: up to 1.5 ° maximum
  Three types of compensation can exist simultaneously and interact with each other

• Other significant advantages
  High transmission efficiency: up to 98-99.5%, with minimal energy loss
  Easy maintenance: adopting modular design, replacing the spring does not require disassembling the entire coupling
  Long lifespan: The service life can reach more than 10 years under standard operating conditions
  Strong environmental adaptability: stable performance within the temperature range of -40 ℃ to+150 ℃

Selection considerations

• Torque demand: including rated torque and peak torque
  

• Shaft diameter size: Ensure matching with equipment shaft
  

• Environmental conditions: temperature, humidity, corrosiveness, etc
  

• Installation space: radial and axial space limitations
  

• Dynamic characteristics: system inertia, critical speed, etc

  Cleaning treatment: Thoroughly clean the contact surface between the shaft and coupling
  Hot installation method: For interference fit, it is recommended to use induction heating method for installation
  Bolt tightening: Use a torque wrench to gradually tighten in diagonal order
  Lubrication treatment: Inject specified lubricating grease during initial installation

• Maintenance and upkeep standards
  Regular inspection: Check the wear and lubrication status of the spring every 3-6 months
  Lubrication cycle: Supplement lubricating grease every 2000 working hours under normal operating conditions
  Wear monitoring: Use a dedicated thickness gauge to check for changes in spring thickness
  Vibration analysis: It is recommended to conduct a vibration spectrum analysis once a year
