Product Description

Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc

Coupling performance

1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

How to select the appropriate coupling type

The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

chain coupling

Can chain couplings accommodate parallel misalignment?

Yes, chain couplings are designed to accommodate a certain degree of parallel misalignment between the connected shafts. Parallel misalignment refers to the situation where the axes of the two shafts are not perfectly aligned and run parallel to each other but at a distance.

Chain couplings have some inherent flexibility that allows them to tolerate a certain amount of parallel misalignment. The flexibility is primarily provided by the roller chain, which can compensate for small parallel displacements between the shafts. This flexibility helps to reduce stress on the coupling components and allows for smooth operation even in the presence of parallel misalignment.

However, it is important to note that chain couplings have limitations in terms of parallel misalignment. Excessive parallel misalignment beyond the specified limits can lead to increased stress, uneven load distribution, accelerated wear, and potential coupling failure. The manufacturer’s specifications and guidelines should be followed to ensure that the parallel misalignment remains within the acceptable range for the specific chain coupling being used.

Proper alignment during installation is crucial to minimize parallel misalignment. The shafts should be aligned as closely as possible to ensure optimal performance and longevity of the chain coupling and the connected machinery or equipment. In some cases, additional measures such as shims or adjustable mounts may be necessary to achieve the desired alignment.

Regular inspection and maintenance of the chain coupling are also important to identify and address any parallel misalignment issues that may arise over time. If significant parallel misalignment is detected, corrective measures should be taken to realign the shafts or consider alternative coupling options that are better suited for parallel misalignment requirements.

In summary, chain couplings can accommodate a certain degree of parallel misalignment, but excessive misalignment should be avoided. Proper alignment during installation and adherence to manufacturer’s guidelines are essential for ensuring optimal performance, reliability, and longevity of the chain coupling and the connected machinery or equipment.

What are the key components of a chain coupling?

A chain coupling consists of several key components that work together to transmit power and accommodate misalignments. Here are the main components of a chain coupling:

  • Sprockets: Sprockets are the toothed wheels that engage with the chain. They are typically made of steel or other durable materials and have specially designed teeth that mesh with the chain rollers. The sprockets provide the driving and driven connections, transmitting torque from one shaft to another.
  • Roller Chain: The roller chain is a series of interconnected links with rollers between them. It is looped around the sprockets, with the rollers engaging with the sprocket teeth. The roller chain transfers the rotational motion from the driving sprocket to the driven sprocket, allowing power transmission between the shafts.
  • Connecting Pins: Connecting pins are used to join the links of the roller chain together, forming a continuous loop. These pins are inserted through the pin holes in the chain links and secured with retaining clips or other fasteners. They ensure the integrity and strength of the chain.
  • Bushings or Bearings: Bushings or bearings are used to support the shafts and allow them to rotate smoothly within the chain coupling. They are typically inserted into the bores of the sprockets and provide a low-friction interface between the shaft and the coupling components.
  • Guard or Cover: In some chain couplings, a guard or cover is added to enclose the sprockets and chain. This serves as a protective barrier, preventing contact with moving parts and reducing the risk of accidents or injuries. The guard or cover also helps to contain lubrication and protect the chain from contaminants.
  • Lubrication: Lubrication is essential for the smooth operation and longevity of a chain coupling. Proper lubrication reduces friction, wear, and noise. Lubricants, such as chain oil or grease, are applied to the chain and sprockets to minimize frictional losses and prevent premature wear.

These components work together to provide a reliable and efficient power transmission in chain couplings. The sprockets engage with the roller chain, and as one sprocket rotates, it drives the chain, causing the other sprocket and the connected shaft to rotate. The roller chain and its components, along with lubrication, allow for flexibility and compensation of misalignment between the shafts.

How to select the right chain coupling for a specific application?

Choosing the appropriate chain coupling for a specific application involves considering various factors to ensure optimal performance and reliable power transmission. Here are some key steps to guide you in the selection process:

  1. Identify Application Requirements: Begin by understanding the specific requirements of the application. Consider factors such as the torque load, speed, misalignment conditions (angular, parallel, axial), and environmental conditions (temperature, moisture, presence of corrosive substances).

  2. Determine Torque and Speed Requirements: Calculate or estimate the torque and speed requirements of the application. This information is crucial in selecting a chain coupling that can handle the transmitted torque and operate effectively at the required speed range.

  3. Evaluate Misalignment Compensation: Assess the expected misalignment conditions in the application. Determine the magnitude of angular, parallel, and axial misalignments that the chain coupling needs to tolerate. This will help in selecting a coupling design that can accommodate the anticipated misalignment without compromising performance or causing excessive stress on the machinery.

  4. Consider Space Limitations: Evaluate the available space for the chain coupling. Measure the shaft-to-shaft distance and ensure that the selected coupling can fit within the available space without interference with other components or structures.

  5. Assess Environmental Factors: Take into account the environmental conditions in which the chain coupling will operate. Consider factors such as temperature extremes, humidity, presence of dust or debris, and exposure to corrosive substances. Choose a chain coupling that is designed to withstand these conditions and is made from materials that offer adequate corrosion resistance.

  6. Consult Manufacturer Specifications: Review the specifications and technical information provided by reputable chain coupling manufacturers. Pay attention to factors such as torque ratings, speed limits, misalignment capabilities, material compatibility, and recommended maintenance practices.

  7. Consider Maintenance Requirements: Evaluate the maintenance requirements of the chain coupling. Assess factors such as lubrication needs, ease of inspection, and adjustment procedures. Choose a coupling that aligns with the maintenance capabilities and resources available in your application.

  8. Seek Expert Advice if Needed: If you are uncertain about the selection process or have specific application requirements that need expert guidance, consult with knowledgeable engineers or technical representatives from the coupling manufacturer. They can provide valuable insights and recommendations based on their expertise and experience.

By following these steps and considering the specific application requirements, you can select the right chain coupling that meets the torque, speed, misalignment, space, and environmental demands of your application. Proper selection will ensure efficient power transmission, reliable operation, and extended lifespan of the chain coupling.
