Choosing manufacturer based on cost

As cost is an essential factor, a manufacturer chosen only based on the lowest price can be detrimental.

There can be a quality compromise if products are of low cost. It may lead to frequent replacement and maintenance costs in the long run.

A balance between cost and quality is to be made to ensure that the chosen manufacturer offers value for money.

Ignoring the need for customization options

Every application has unique requirements; therefore, if the customization options are ignored, it may lead to suboptimal performance.

Choosing a coupling supplier with customization options showcases flexibility and a commitment to meet the customers' needs. On the contrary, ignoring customization options limits the potential benefits of coupling solutions.

Neglecting to check with industry standards

If the manufacturer's products are not verified according to industry standards, it may lead to safety and performance issues.

Couplings that do meetn't required standards lead to leading machinery and personnel. Requesting and reviewing the certificates and compliance documents is necessary to ensure selected manufacturers adhere to industry standards.

Failing to assess long-term support and warranty options

A manufacturer who doesn't give long-term support and warranty options may lead to several challenges.

Choosing the best coupling supplier provides ongoing support and warranties that instill confidence in the durability of their products. Failing to assess such aspects may lead to difficulties addressing problems during downtime.

Advances in Material Science for Improved Coupling Performance

As material science continues to evolve, it has improved and developed new materials in coupling manufacturing. It has continuously introduced new compounds and alloys.

A manufacturer willing to use advanced materials speaks to their commitments and provides state-of-the-art solutstate-of-the-arthould be at the forefront of material science and engage in continuous improvements, maintaining the latest material trial that enhances the performance of couplings.

Conclusion

Choosing the proper coupling manufacturer requires a thorough understanding and exploration. It is necessary to check on manufacturers' reputations, experience, product quality, customization options, strong technical support, and industry standards, and be mindful of costs and guiding points.

Choosing the Right Mechanical Coupling

Mechanical couplings can be divided into four main categories:

  • Flexible couplings
  • Torsionally rigid couplings
  • Rigid couplings
  • Hydrodynamic couplings

There is a wide variety of couplings available on the market. Sometimes, it’s easy to know which one to choose. For example, if there is no significant misalignment, a rigid coupling will be the cheapest and most reliable solution. If torsional damping is the main concern, then a jaw coupling is the best choice.

Couplings have several functions and advantages:

  • Transmit movement from the drive side to the driven side of a rotary system
  • Quickly connect two components of a system (for example, a motor and a pump) and easily separate them for maintenance purposes
  • Compensate for axial, radial, or angular misalignment
  • Add more flexibility to a system
  • Absorb vibrations and mechanical shocks
  • Protect equipment from torque overloads

The choice of coupling should be based on the following criteria:

  • Type of misalignment between the two axes (radial, angular, or axial)
  • Maximum torque to be transmitted (generally, in the technical characteristics of the coupling, the manufacturer indicates the maximum torque allowed)
  • Characteristics and operating conditions of the drive side and the driven side of the system (frequency of starts, shocks and vibrations, operating temperature, etc.)
  • Maximum rotation speed
  • Coupling dimensions
  • Diameter of input and output shafts
  • Cost/performance ratio

The service life of the coupling in relation to its replacement cost is an important selection criterion. In certain cases, for example, if downtimes are particularly costly or it is difficult to dismantle the components to carry out maintenance on the coupling, it is advisable to opt for a coupling with a longer service life that requires little or no maintenance.

System performance versus cost must also be considered. For example, if the motor or driven components are expensive or fragile, you should opt for a more expensive coupling that exerts softer reactive forces.

Flexible couplings consist of rigid parts and an elastic connection. This elastic element makes them torsionally flexible. As such, they can compensate for certain misalignments but are mainly intended to absorb shocks and vibrations in the transmission resulting from variations in torque (from a pulsating torque, for example).

There are various types of flexible couplings, such as elastomer couplings, jaw couplings, tire couplings, grid couplings, etc.

They have various applications in conveyor belts, mixers, pumps, etc.

Choosing a coupling of this type depends on several factors, such as the space available for mounting it, the durability required, and the transmission capacity.

The operating temperature is an equally important aspect. The product’s technical characteristics usually indicate the temperature range in which the coupling can operate.

As with any mechanical assembly, it is difficult to achieve perfect alignment between the parts. As such, there are misalignments between the drive shaft and the driven shaft that can complicate the transmission of movement. These misalignments can be axial, radial, or angular. Misalignment can lead to fatigue or wear of the coupling. Therefore, when selecting a coupling, you must consider the speed of rotation, the maximum permissible misalignment, and the torque the assembly can withstand. This information is provided by the manufacturer for each product.

When transmitting high powers, ensure that the torque transmitted is less than the maximum torque indicated in the product’s technical characteristics, leaving a margin proportional to the expected misalignment. The rotational speed of flexible couplings is limited, so they are not suitable for shafts with high rotational speeds, especially if there is significant misalignment.

Concerning mechanical shocks and vibrations, these couplings can generate vibrations if they start to show backlash due to wear. Fixing these assemblies with a flange helps prevent marks from being produced on the shafts, offering greater resistance to sudden reversals and vibrations.

Rigid couplings are, as their name suggests, permanent rigid couplings (or joints) connecting two shafts or shaft/hub. Unlike flexible couplings, they do not allow misalignment.

They ensure that machines can be driven without any unwanted movement between the shafts. They have a very low capacity to absorb misalignment, making them ideal for transmissions with high torques and no misalignment between the shafts. They are also suitable for systems with low rotational speeds.

Rigid couplings are mounted precisely between the two shafts and are easy to assemble, disassemble, and adjust. They are unable to accommodate misalignment. If misalignment does occur, due to assembly misalignment or thermal expansion during operation, the use of rigid couplings can result in significant reactive forces on the bearings. However, if these misalignments are very small and the bearings are robust, rigid couplings will be the best choice both for their low cost and their durability.
