Ameridrives Amerigear® Couplings


Ameridrives Amerigear® Couplings are the first and finest flexible couplings featuring fully-crowned gear teeth.

In contrast with ordinary gear tooth forms, Amerigear fully-crowned tooth technology represents the ultimate achievement in the art of gear tooth design, with all three working portions of the tooth being crowned.

Crowned Flanks
Flanks of the teeth are crowned so that tooth thickness is greatest at the center of the tooth.

Crowned Tips
Tips of teeth are crowned with a radius equal to the outside of the gear element.

Crowned Chamfers
Faces of the teeth adjacent to the tips are chamfered to eliminate interference with the sleeve tooth fillets.

As a result of this “triple-crown” machining, the teeth act much like a rocking chair, capable of sliding freely in the axial direction without digging or gouging the internal mating teeth. Because of this design advantage, Amerigear flexible couplings with fully-crowned gear teeth offer operational benefits, including maximum load-carrying capacity, minimum size, maximum reliability and long life. Optimum separation of gear meshes permits high parallel offset capacity. Units feature precision-machined medium carbon steel hubs and sleeves.

Features:

  • Over 10" diameter bore capacity
  • Highest torque ratings at a full 1-1/2 degree of misalignment
  • Torque capacity of over 1,000,000 in.lbs.
  • High axial capacity
  • Standard design allows for installation flexibility (reverse mount hubs for unexpected shaft gaps)
  • AGMA standard design for interchangeability
  • Both O-ring and metal seal models are available
  • Strong, rigid floating sleeve
  • Positive dust-tight seals
  • Seals enshrouded to prevent damage
