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.

A5 Form Flex Couplings
TB Wood’s A5 Form-Flex couplings are designed for transmiting torque while compensating for axial, angular & parallel misalignment between two connected shafts. These easy-to-install couplings protect equipment from shock, vibration & misalignment, and are widely used in cooling fan drive applications. These metal couplings have zero backlash & high torsional stiffness and are ideal for printing applications & positioning systems. The brand’s A5 Series flexible couplings are available in 0.48, 1.27, 3.49, 6.03 & 18 HP ratings at 100 rpm. Choose from a wide range of TB Wood’s flex couplings in 5, 10, 20, 25 & 35 sizes on Raptor Supplies.

A5C/B5C Form Flex Couplings
TB Wood’s A5C / B5C Form-Flex couplings are spacer style couplings configured to minimise shaft separation. Two fully machined steel hubs & one flat block spacer are included in composite spacer Form-Flex couplings to eliminate the need for high maintenance center support bearings. These A5C / B5C Series couplings have a zero backlash design and offer elastomeric & gear coupling replacements without the need for lubrication. They can also be used in combination with floating shaft couplings and pillow block bearings to span long distances. Choose from a wide variety of these couplings, available in torque ratings ranging from 2200 to 34000 lb-inch on Raptor Supplies.
