This design provides good oil film characteristics for efficient lubrication. Crowned Tips Tips of teeth are amerigear coupling catalogue with a radius equal to the outside of the gear element.

The crowned tip contacts the root of internal gear teeth in the external sleeve, accurately piloting the sleeve with true concentric ball-andsocket action.

This permits minimum diametral amerigear coupling catalogue clearance and centers the sleeve physically to assure good dynamic balance characteristics under various loading and misalignment conditions. Crowned Chamfers Faces of the teeth adjacent to the tips are amerigear coupling catalogue to eliminate interference with the sleeve tooth fillets.

This allows the true involute flanks of the gear teeth to be in contact with the sleeve teeth and assures freedom to misalign. In accordance with our established policy to constantly improve our products, the specifications contained herein are subject to change without notice.

Large massive shafting, loosely mounted in sleeve bearings and merely joined together by rigidly bolted flanges, cannot provide efficient mechanical power transmission.

Especially today, as machine designers and builders demand higher speeds, higher torques, and higher misalignment capacities, the need for flexibly connecting this equipment becomes apparent. A flexible coupling is necessary since it is practically impossible to achieve and amerigear coupling catalogue perfect alignment of coupled rotating shafts.


During initial assembly and installation, precise alignment of the shaft axes is not only difficult to achieve but in many cases it is economically unfeasible. During operation, amerigear coupling catalogue is even more difficult to maintain. Shaft misalignment caused by uneven bearing wear, flexure of structural members, settling of foundations, thermal expansion, shaft deflection and other factors is an operating certainty.

Because these factors are extremely difficult to control, a flexible coupling serves as an ideal answer to compensate or amerigear coupling catalogue the effects of unavoidable misalignment and end movement of coupled shafts. A amerigear coupling catalogue coupling must provide three basic functions: 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.

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.

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. Three types of misalignment must be effectively accommodated by a flexible coupling.


Parallel Offset axes of connected shafts are parallel, but not in the same straight line. Angular axes of shafts intersect at center point of amerigear coupling catalogue, but not in the same straight line.

Combined Angular-Offset axes of shafts do not intersect at point of coupling and are not parallel.


Increased tooth contact area improves the load-carrying capacity of the teeth regardless of operating conditions and provides amerigear coupling catalogue piloting action at all misalignments. As a result, connected equipment is able to operate at higher torques, speeds, and misalignments with resultant longer life.
