Gear Flexible Coupling

Types of Gear Flexible Coupling
  • Type GDE (Double Engagement Coupling)
  • GDEL (Double Engagement Large Coupling)
  • Type GSE (Single Engagement Coupling)
  • GSEL (Single Engagement Large Coupling)
  • Type GSCD (Spacer Coupling Double Engagement)
  • Type GH (Gear Horizontal Sliding)
  • Type GDBW / GSBW (Brake Wheel Double/Single Engagement)
  • Type GFS (Single Engagement Coupling with Floating Shafts)
  • Type SS/CC (Gear Double / Large)
  • Type SE/CE (Gear Single /Large)
Characteristics of Gear Flexible Coupling

The shafts may be misaligned by various causes, such as heat, vibration and worn bearing, etc. When the initial alignment is not correct and heavy stress is imposed on the coupling, life time will be short. Any or all of the misalignments shown in the above illustrations are present in every connected drives.

Advantages of Gear Flexible Coupling

Gear Coupling takes the method of coupling by linking sleeve and Hub With shaft and our gear coupling adoped AGMA method(U.S.A) in manufacturing of gear which is the most imporant in gear Coupling so that we can maintain high quality in product.

  • Light weight, small size, long life and very little loss of transmitting power.
  • It prevents leakage of lubricants by using gasket at the connection point, and it's convenient to set by concavo-convex style.
  • Gear Coupling permits parallel, angular and end floating misalignments by crown gear form of hub tooth.
    Parallel Misalignment:
    The driving and driven shafts are parallel to each other, but not on the same straight line.
    Angular Misalignment:
    The driving and driven shafts cross to each other with an angle an the same straight line.
    End Floating:
    The driving and driven shafts slide sliqhtly each other on the center line.
  • The coupling made of S45C has a good endurance to high speed and peak load and we can use some special materials.

The crowned hub teeth provide larger contact area, lower the stress.

Applications of Gear Flexible Coupling
  • Heavy load, but compact design coupling required
  • High speed up to 5,000rpm(Depending on size, refer to the data.)
  • Low speed but high starting torque required.
  • End float application
  • Spacer required due to longer distance between shaft ends
  • Low load and light weight application is not recommended.

Standard Material
SM 45C - N SM 45C - H NBR

Under the heavy load, high speed and corrosion environment, special materials will be required.
