Jaw Coupling with Elastomer Spider - Shreeji Gears

Versatile Jaw Couplings

Shreeji Gears is a leading jaw coupling manufacturer, offering reliable and cost-effective solutions for general-purpose power transmission. Jaw couplings consist of two metallic hubs and an elastomeric spider.

The interlocking jaws of the hubs engage with the spider, transmitting torque while providing excellent vibration damping and shock absorption. This makes them ideal for various industrial applications like pumps, fans, and conveyors.

Understanding Jaw Couplings

Jaw couplings transmit torque through the compression of an elastomeric spider placed between the jaws of two hubs. The design is simple yet effective, allowing for misalignment compensation. The spider's material and hardness determine the coupling's characteristics.

Key Advantages:

  • Cost-Effective: One of the most economical flexible coupling types.
  • Vibration & Shock Damping: The elastomer spider effectively absorbs torsional vibrations and shock loads.
  • Fail-Safe Design: If the spider fails, the hub jaws interlock, allowing continued (though noisy) power transmission for a short period.
  • No Lubrication: Requires no lubrication, simplifying maintenance.
  • Variety of Spiders: Different elastomer materials (PU, NBR, Hytrel®) offer varying levels of torque capacity, damping, and temperature resistance.

Considerations:

  • Backlash: Standard jaw couplings have some backlash. Specialized spider designs can minimize this for motion control applications.
  • Spider Wear: The elastomer spider is a wearing part and may require periodic inspection and replacement.
