Amerigear O’Ring

Ameridrives Amerigear O'Ring Seal Gear Couplings were designed in the early 1950's when the Amerigear Fully Crowned Gear Tooth was patented. In contrast with ordinary gear tooth forms, all three working portions of the tooth are crowned. The teeth are capable of sliding freely in the axial direction without digging or gouging the internal mating teeth. This design offers operational benefits of maximum load-carrying capacity with minimum size, maximum reliability and long life.

Amerigear® Fully Crowned Gear Tooth

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...often copied, but never equaled.

Functions of a Coupling

Torque Physically couple together two rotating shafts for efficient transmission of mechanical power, transferring the torque of one shaft to the other, directly and with constant velocity.
Angular Compensate for all types of misalignment between rotating, connected shafts without inducing abnormal stresses and loads on connected equipment and without tangible loss of power.
Axial Compensate for end or axial movement of the coupled shafts, preventing either shaft from exerting excessive thrust on the other and allowing each to rotate in its normal position.

Amerigear Mill Spindles

SM Series

Since the development of gear type spindles, their use has been accepted on all types of mill drives. The SM Mill Spindle is used on heavy-duty, high-torque applications requiring rugged strength such as metals rolling mill main drives and similar heavy equipment. The patent pending Advanced Gear Design increases capacities up to 300%.

Mill type spindles deliver maximum torque capacity under severe shock loads, while operating at relatively high angles. Gear sections are made from forged alloy steels with heat treated teeth. Hub gear teeth are Fully-Crowned to provide maximum torque capacity with minimum backlash. Onepiece, molded lip-type seals, designed for operation under misalignment conditions, provide the most effective closure available to keep lubricant in and contaminants out. All spindles are designed so that the contact point of the thrust button is located on the centerline of the gear mesh. This provides ball and socket action, rather than the sliding motion that occurs if the contact point is located on the thrust plate.



Ameriloc Locking Devices

Ameridrives Couplings now offers a full line of  Ameriloc internal and external locking devices and shaft couplings. All units are custom-engineered, manufactured, and tested to precise tolerances to meet specific customer requirements and provide years of trouble-free service.
