Product Description
Gear Coupling
Triple crowned teeth hub is manufactured on a fully automatic hobbing machine with built in crowing attachment which is controlled by hydraulic & electronic systems. Under the misalignment condition of 2 shafts on the equipment, due to the curvature on teeth flank the contact area is much more and therefore, there is increase in life of coupling.
Gear couplings are power intensive and considered as the king of the coupling types. You would see the gear couplings being adopted for wide range of application in drive technologies. Hence, we love love gear coupling (and I think, you would too!).
Gear Couplings and Universal Joints
Gear couplings and universal joints are used in similar applications. Gear couplings have higher torque densities than universal joints designed to fit a given space, while universal joints induce lower vibrations. The limit on torque density in universal joints is due to the limited cross sections of the cross and yoke.
The gear teeth in a gear coupling have high backlash to allow for angular misalignment. The excess backlash can contribute to vibration.
Gear couplings like all other shaft coupling devices perform the basic functions of connecting 2 shafts to transmit torque and compensate for misalignment. Gear couplings though are the king of the coupling types. While each type of coupling has its own niche, gear couplings are more power intensive, have more modifications, and a wider size, torque, and bore range than all the others. Gear couplings can also perform at extremely high rates of speed. As inferred by the name, gear couplings use the meshing of gear teeth to transmit the torque and to provide for misalignment.

Can Spacer Couplings Handle Misalignment Between Shafts?
Spacer couplings are designed to handle some degree of misalignment between shafts, but their capacity to do so depends on the specific coupling design and the magnitude of the misalignment.
Unlike flexible couplings, which can accommodate significant misalignment through their elastic properties, spacer couplings are generally less forgiving when it comes to misalignment. However, they can tolerate limited angular, parallel, and axial misalignment.
The amount of allowable misalignment for a spacer coupling depends on factors such as:
- Coupling Design: Some spacer couplings, such as the sleeve or muff coupling, have relatively more flexibility and can handle more misalignment than others.
- Coupling Size: Larger spacer couplings may have a higher misalignment capacity than smaller ones.
- Material: Certain materials used in manufacturing spacer couplings may provide some level of flexibility to accommodate misalignment.
- Application Requirements: The specific needs of the application, including the type of connected equipment and the expected operating conditions, will influence the acceptable misalignment range.
It is essential to consider the manufacturer’s specifications and recommendations when using spacer couplings to ensure that the misalignment falls within the permissible limits. Excessive misalignment can lead to premature wear, increased vibration, and reduced coupling life. Therefore, precise alignment during installation is critical for optimal performance and longevity of the spacer coupling and the connected machinery.
How Does a Spacer Coupling Handle Angular, Parallel, and Axial Misalignment?
A spacer coupling is a type of flexible coupling that is designed to accommodate different types of misalignment between shafts. Here’s how it handles angular, parallel, and axial misalignment:
1. Angular Misalignment: Angular misalignment occurs when the axes of the two shafts are not parallel but intersect at a certain angle. A spacer coupling can handle angular misalignment by allowing the flexible element (such as an elastomeric or metallic component) to flex and bend when the shafts are not perfectly aligned. This bending action allows the coupling to compensate for the angular displacement between the shafts and transmit torque smoothly.
2. Parallel Misalignment: Parallel misalignment occurs when the axes of the two shafts are parallel but are offset laterally. A spacer coupling can handle parallel misalignment by virtue of its design. The spacer element (a cylindrical piece that connects the two coupling halves) provides the required lateral space between the shafts. This space allows the shafts to have a slight offset without inducing excessive stress on the machinery, thereby minimizing the risk of premature wear or failure.
3. Axial Misalignment: Axial misalignment occurs when the two shafts move closer together or farther apart along their axis. Some spacer couplings may have limited axial movement capabilities, which can help accommodate slight axial misalignment. However, it’s essential to ensure that the axial displacement is within the coupling’s specified limits to avoid overloading the coupling or the connected equipment.
Overall, spacer couplings are designed to be flexible and provide some degree of misalignment accommodation, but their ability to handle misalignment depends on their specific design and material properties. It’s essential to select the appropriate type and size of spacer coupling based on the expected misalignment and operational requirements of the machinery to ensure optimal performance and longevity of the coupling and the connected components.
