AA Form Flex Couplings
TB Wood's Form-Flex couplings connect two shafts and transmit torque / power effectively from one shaft to the other. They compensate for angular, parallel and axial misalignment between two connected shafts at a closer distance. These AA couplings feature a flexible disc to minimise misalignment forces and allow easy interchangeability, thereby reducing downtime & maintenance time. Choose from a wide range of these Form-Flex couplings, available in torque ratings ranging from 2363 to 17010 lb-inch on Raptor Supplies.

ASpline Shafts And Couplings
Hub City spline shafts are specially designed for transmitting high amount of torque force and rotation. These plain and involute splined shafts feature 1215 cold-rolled steel to deliver fair vibration damping and excellent chemical resistance. We also offer Hub City couplings in 1144 stress-proofed steel to connect and transmit torque between two rotating shafts. These couplers feature Kwik-D-Tach connection for safe and secure attachments.
Working Mechanism
- The shafts of the machinery are positioned in such as way that their ends are facing each other.
- The spline shaft is inserted securely into the grooves of the coupling.
- The coupling is then fastened onto the end of the other shaft by using bolts or clamps.
- When torque is applied to one of the shafts, it is transmitted through the spline shaft and coupling to the other shaft, causing both shafts to rotate at the same speed.
Features
Lovejoy U-Type Couplings :
- These Uniflex couplings are used in a variety of applications, including high misalignment, space limitations, high temperature and exceptionally low backlash or windup conditions.
- They feature a flexible triple-wound spring design that helps transmit torque between two rotating shafts while accommodating vibrations.
- These compact couplings contain two hubs that are brazed to the speed spring pack to create a durable one-piece flexible coupling.
- They are supplied with keyways and set screws for offering a secure and accurate connection between the coupling and the shafts.
- These short-version couplings can accommodate different length requirements and provide a maximum OAL (overall length) tolerance of 1/8 inches.
- They are ideal for applications like textile equipment, robotic / positioning, conveyors, carton folding and glueing equipment, machine tools, blowers and the steering mechanism.
TB Woods Form-Flex Couplings :
- They help transmit torque while compensating for angular, axial and parallel misalignment between two connected shafts.
- These spacer couplings allow enough space for installation and maintenance without moving the connected machinery.
- They feature a metal disc that uses a double hinge effect through two flexible discs and a spacer, causing both shafts to rotate at the same speed.
- If the shafts are misaligned, the flexible element deflects and absorbs the displacement, reducing the transmission of vibration and shock between the two shafts.
Frequently Asked Questions
What is overall length tolerance?
OAL (overall length tolerance) refers to the allowable deviation from the nominal or desired length of the coupling. It helps to position and align the coupling on the shafts it is connecting.
What is the purpose of keyways in Lovejoy couplings?
Keyways are grooves or slots that are machined into the bore of the coupling hub and include a matching key that is installed in the keyway to connect the hub to the shaft. These keyways help transmit torque, ease installation and provide accurate alignment between the shaft and the coupling.
How to maintain a spline coupling?
- Regular visual inspections are needed to identify any signs of wear or damage of the spline coupling, such as cracks and corrosion.
- Ensure the coupling is properly aligned to maintain smooth operation and prevent premature wear.
- Regularly lubricate the coupling to prevent wear and reduce friction.
- Ensure that spline couplings are not subjected to overload conditions, as this can cause permanent deformation and reduce the strength of the spline teeth.
How do I select the right type of shaft coupling for my application?
The choice of coupling depends on shaft misalignment, torque requirements, speed and environmental conditions.
What is the difference between rigid couplings and flexible couplings?
Rigid couplings do not allow any angular or parallel misalignment between shafts. They provide a solid, backlash-free connection. In contrast, flexible couplings accommodate some degree of misalignment and are often used to dampen vibrations and shock loads in machinery.
How do I calculate the torque capacity of a spline shaft?
- To calculate the torque capacity of a spline shaft, you can use the formula:
- Torque (T) = Shaft Diameter (D) x Material Strength (S) x Safety Factor (SF)
What is the difference between external spline and internal spline configurations?
External spline refers to the presence of the splines on the outside surface of a shaft, while internal spline refers to the splines inside a cylindrical bore.
How does rigid, flexible and fluid connection coupling differ from each other?
Rigid couplings provide a solid connection with no flexibility, flexible couplings offer misalignment compensation, and fluid couplings use hydraulic principles for torque transmission and speed control.
