JS Grid Flex Coupling is an advanced mechanical transmission device named after its unique snake shaped spring structure. This type of coupling achieves torque transmission by installing a serpentine coil spring between two half couplings, combining the advantages of elastic couplings and rigid couplings, and is widely used in modern industrial transmission systems.

The JS Grid Coupling mainly consists of the following parts:

• Half coupling (wheel hub): usually forged from high-strength alloy steel, connected to the drive shaft and the driven shaft
  

• Serpentine spring: a high elasticity spiral spring made of special alloy steel, coiled in a serpentine shape
  

• Shell: protects the spring and accommodates lubricating grease to prevent external contaminants from entering
  

• Sealing device: maintain internal lubrication to prevent leakage
  

• Fasteners: high-strength bolts and nuts to ensure reliable connection

When the driving shaft rotates, torque is transmitted to the serpentine spring through the half coupling. The elastic deformation of the spring absorbs impact and vibration, and then smoothly transmits power to the driven shaft. The special shape of the snake shaped spring enables it to undergo gradual elastic deformation when subjected to torque, achieving gentle power transmission.

Main performance characteristics

• High torque transmission capability: The large contact area of the serpentine spring ensures high torque transmission efficiency
  

• Excellent vibration damping performance: can absorb up to 30% of vibration and impact loads
  

• Angle compensation capability: allows for significant axial, radial, and angular deviations (typically up to 1.5 ° for angular deviations and up to 0.5mm for radial deviations)
  

• No lubrication maintenance required: Most models adopt long-term lubrication design, with a long maintenance cycle
  

• Long life design: High quality materials and special heat treatment processes ensure an ultra long service life

JS Grid Couplings are widely used in the following industries:

• Power industry: generator sets, wind turbines, hydroelectric equipment
  

• Petrochemical industry: rotating equipment such as compressors, pumps, fans, etc
  

• Metallurgical industry: rolling mills, crushers, ball mills
  

• Shipbuilding industry: main propulsion system, auxiliary transmission
  

• Mining Machinery: Elevators, Conveyor Equipment
  

• General machinery: various transmission systems that require vibration reduction and compensation for deviations

Selection considerations

• Transmission torque magnitude and variation characteristics
  

• Shaft diameter size and connection method (cone sleeve, keyway, etc.)
  

• Operating speed range
  

• Environmental conditions (temperature, humidity, corrosiveness, etc.)
  

• Installation space restrictions
  

• Do you need a special level of protection

Installation precautions

• Ensure that the shaft end is clean and free of burrs
  

• Check that all components of the coupling are undamaged
  

• Tighten the bolts according to the torque value provided by the manufacturer
  

• Manually rotate and check for any abnormalities after installation
  

• Perform low-speed trial operation before initial operation

Although the JS Flex Grid Coupling is designed as a maintenance free type, to ensure long-term reliable operation, it is recommended to:

• Check the bolt tightening status every 6 months
  

• Check the wear of the spring once a year
  

• Supplement specialized lubricating grease every 2-3 years (depending on working conditions)
  

• Regularly check the condition of the seals to prevent grease leakage
  

• When there is abnormal vibration or noise, the machine should be stopped immediately for inspection

The JS Grid Coupling with its excellent performance and reliability, will continue to play an important role in the industrial transmission field, providing efficient and smooth power transmission solutions for various rotating machinery.
