AP Form Flex Couplings

TB Wood's AP Series Form-Flex couplings transfer mechanical power from one shaft to another. They are ideal for pumps, centrifugal & screw compressors, fans, blowers, mixers and turbo compressors. These couplings offer wider separation between two shafts than other couplings, allowing servicing operations without moving or disconnecting the equipment. They accommodate angular, parallel and axial misalignment. Choose from a wide range of these Form-Flex couplings, available in 1.19, 1.38 and 1.63 inch bore sizes on Raptor Supplies.

Spline 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.

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.
