HA-CO Elastomer Couplings and Jaw Couplings

Backlash-free and vibration-damping couplings for reliable drive systems

A reliable and precise connection between a motor and driven shaft is essential in many industrial machines. It is not only important that torque is transmitted accurately, but also that vibrations and shocks are absorbed as effectively as possible. HA-CO elastomer couplings and jaw couplings provide a compact and flexible solution for these applications.

These high-quality couplings are manufactured by HA-CO GmbH and are designed for applications where backlash-free torque transmission, vibration damping and compensation of shaft misalignment are important.

Thanks to the elastomer spider, the coupling can compensate for small parallel, angular and axial misalignments between the two shafts. At the same time, the elastomer provides a damping effect that helps reduce vibrations and shocks within the drive system.

What is a HA-CO elastomer coupling?

An elastomer coupling, also known as a jaw coupling, is a mechanical shaft coupling used to connect two shafts and transmit torque from the drive to the driven machine.

The coupling consists of two hubs with an elastomer spider positioned between them. The elastomer spider forms the flexible and damping element between the two hubs.

The elastic properties of the spider allow small deviations between the two connected shafts to be compensated while maintaining backlash-free torque transmission.

The elastomer spider can compensate for:

• Axial misalignment.

• Parallel or radial misalignment.

• Angular misalignment.

• Minor assembly and manufacturing deviations.

The elastomer also provides damping of vibrations and shocks that can occur during machine operation.

Key benefits

HA-CO elastomer couplings combine backlash-free torque transmission with vibration damping and compensation of shaft misalignment.

The main benefits include:

• Backlash-free torque transmission – provides accurate torque transmission between both shafts.

• Vibration damping – the elastomer absorbs vibrations and shocks within the drive system.

• Compensation of shaft misalignment – small axial, parallel and angular deviations can be compensated.

• Compact construction – suitable for applications where installation space is limited.

• Easy installation – various versions can be easily plug-in mounted and can be disconnected without completely dismantling the coupling.

• Different elastomer hardnesses – different spider hardnesses allow the coupling to be adapted to the specific application.

• Low moment of inertia – various versions are suitable for dynamic drive applications.

• Electrical insulation – depending on the version, the elastomer spider can provide electrical insulation between the two shafts.

• Suitable for high speeds – various HA-CO versions are designed for applications with high rotational speeds.

• Suitable for servo motors – certain versions are particularly suitable for precision servo drives.

Different HA-CO elastomer couplings

The HA-CO range includes various elastomer couplings. The different versions vary in terms of dimensions, torque range, speed, construction and elastomer spider characteristics.

OpenSupply offers various versions, including the SKK, SKL, SKM, SKP, SKS and SKT.

HA-CO SKK

The SKK is an elastomer coupling designed for reliable and backlash-free torque transmission.

This version is suitable for various industrial drive systems and is available in different torque and speed configurations.

HA-CO SKL

The SKL is an elastomer coupling for applications where a combination of reliable torque transmission and vibration damping is important.

This version is suitable for various industrial drive systems where a flexible and reliable connection between two shafts is required.

HA-CO SKM

The SKM is a compact elastomer coupling with aluminium clamping hubs. This version features an elastomer spider and is designed with good damping characteristics.

The SKM provides backlash-free torque transmission through preloading, is easy to plug in and has a low moment of inertia. This makes it suitable for applications including servo motors.

HA-CO SKP

The SKP is a precision elastomer coupling suitable for applications where accurate torque transmission and dynamic performance are important.

This version combines a compact construction with the advantages of an elastomer spider, making it suitable for various industrial drive systems.

HA-CO SKS

The SKS is a compact elastomer coupling suitable for a wide range of industrial applications.

Its compact construction and elastic characteristics make this version suitable for drive systems where both accurate torque transmission and vibration damping are important.

HA-CO SKT

The SKT is an elastomer coupling designed for applications where a reliable and vibration-damping connection between two shafts is required.

This version combines reliable torque transmission with the flexibility and damping characteristics of the elastomer.

The elastomer spider as a flexible element

An important component of an elastomer coupling is the elastomer spider. It is positioned between the two hubs and forms the connection between the driving and driven shaft.

The spider not only transmits torque but also has an important damping function. This allows vibrations and shocks generated by the motor or machine to be partially absorbed.

OpenSupply also offers elastomer spiders as individual components. Depending on the application and required characteristics, the elastomer spider can therefore be replaced or adapted.

Different hardnesses for different applications

Not every machine has the same requirements for a coupling. For this reason, elastomer spider couplings are available with different hardness levels.

The hardness of the elastomer spider affects the characteristics of the coupling, including its damping properties and the behaviour of the connection during torque transmission.

This allows the coupling to be adapted to the specific requirements of the machine.

For applications where a high level of vibration and shock damping is required, different characteristics may be preferred compared with a drive where the most precise transmission of movement is the main priority.

Backlash-free and vibration-damping torque transmission

An important advantage of a HA-CO elastomer coupling is the combination of backlash-free torque transmission and vibration damping.

The preload between the hubs and elastomer spider allows torque to be transmitted without unwanted play. At the same time, the elastic material helps damp vibrations and shocks within the drive system.

This makes the couplings suitable for machines where both precise movement and smooth drive operation are important.

Easy to install and maintain

Another important advantage of various HA-CO elastomer couplings is their simple installation.

The coupling can be easily plug-in mounted, allowing the connection between the shaft and motor to be disconnected quickly. This means that all coupling screws do not have to be loosened every time the coupling is removed.

This can be particularly useful for machines that require regular maintenance, inspection or replacement of components.

The compact construction also makes the couplings suitable for drive systems where available installation space is limited.

Easy integration into your drive system

Elastomer couplings can be used between different types of drive components, including motors, servo motors, drive shafts and machine components.

When selecting the correct coupling, factors such as the following should be taken into consideration:

• Required nominal torque.

• Maximum torque.

• Operating speed.

• Shaft diameters.

• Available installation space.

• Required damping characteristics.

• Possible shaft misalignment.

• Desired elastomer spider hardness.

The different HA-CO versions and elastomer hardnesses allow the coupling to be adapted to the specific requirements of the drive system.
