Amerigear® Gear Couplings
Amerigear®.., the first, the finest… flexible coupling with Fully-Crowned Gear Teeth. In contrast with ordinary gear tooth forms, the Amerigear Fully-Crowned Tooth represents the ultimate achievement in the art of gear tooth design, wherein all three working portions of the tooth are crowned.
As a result, 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 of maximum load-carrying capacity with minimum size, maximum reliability and long life.

Amerigear® Class I Gear
Amerigear Class I High Performance Gear couplings with fully crowned gear teeth are designed for higher torque, higher speed, and higher misalignment to accommodate the increased performance demands of modern, rotating equipment. Standard and custom designs are manufactured to precision tolerances to meet weight, size, temperature, speed and misalignment requirements. Higher torque, higher speed, and higher misalignment requirements; this is the trend in rotating mechanical equipment. Let Ameridrives Couplings, first to apply the Fully Crowned Tooth concept to a gear-type coupling in the early 1950’s, supply a coupling for your needs. Our engineering know-how in tooth design, material and lube selection, and manufacturing techniques stands ready to serve you. We can supply you with one of our conventional Class I high performance designs, or let us custom-design a coupling for your application.
