Chain Couplings

The chain coupling is composed of a duplex roller chain and a pair of coupling sprockets. The function of connection and detachment is done by the joint of the chain. It has the characteristic of being compact and powerful, excellent durability, safe and smart, simple installation and easy alignment. The chain coupling is suitable for a wide range of coupling applications.

Parameters of Chain Couplings



What Are Chain Couplings?

Chain couplings are mechanical devices for connecting 2 shafts. They consist of 2 rows of roller chains with sprockets that engage them. The shafts are then cranked to move the coupling. Chain couplings are available in a range of sizes and torque capacities.

Chain couplings are all steel and compact for space-constrained applications. They transmit high torques and offer positive power transmission. Unlike conventional couplings, chain couplings require less space and are easily installed and dismantled. They also provide a balanced unit operation, which is essential for high torques. Chain couplings are typically used in low-speed, high torque applications. They also offer a high degree of flexibility and allow for misalignment of up to 2 degrees between the shafts.

Advantages of a Chain Coupling

A chain coupling is a type of transmission system that uses a single common chain, meshing with 2 parallel sprockets to transfer power from 1 shaft to the other. A chain coupling comes in various varieties, including roller chain coupling, toothed chain coupling, and nylon chain coupling. The benefits of a chain coupling include its simplicity, reliability, and low installation accuracy. A chain coupling is a common option for shafting transmission applications, especially in low-speed, high-torque applications.

One of the most important advantages of chain couplings is their high-torque capability. Because they are made of 2 flanges linked by a duplex roller chain, they are ideal for high-torque applications. They can accommodate up to 2 degrees of misalignment, which makes them a common choice for applications that require high torque. Another advantage of chain couplings is their ease of installation and low-maintenance requirements.

Besides being easy to assemble, a chain coupling also keeps the 2 shafts perfectly aligned. It also minimizes shock and vibrations during power transmission. It should also have a low-profile design and be easy to fit between 2 shafts. And, of course, it should be CZPT to transmit power from 1 shaft to the other. These features are essential for high-speed applications.

How to Install a Roller Chain Coupling?

Ever-power chain couplings feature a unique single-pin design that greatly simplifies the installation process. Simply follow these simple steps.

  • Install the oil seal on each hub
  • Adjust the alignment of the shaft and coupling assembly
  • Adjust the distance between the sprocket faces
  • Thoroughly lubricate the coupling chain
  • Install the chain to the coupling using the single pin coupling ring
  • Firmly close and secure the coupling cover (optional, depending on operating conditions)

The chain coupling installation process is simpler and faster than conventional rigid couplings.

Standard Length Splined Shafts

Standard Length Splined Shafts are made from Mild Steel and are perfect for most repair jobs, custom machinery building, and many other applications. All stock splined shafts are 2-3/4 inches in length, and full splines are available in any length, with additional materials and working lengths available upon request and quotation. CZPT Manufacturing Company is proud to offer these standard length shafts.

Disc brake mounting interfaces that are splined

There are 2 common disc brake mounting interfaces, splined and center lock. Disc brakes with splined interfaces are more common. They are usually easier to install. The center lock system requires a tool to remove the locking ring on the disc hub. Six-bolt rotors are easier to install and require only 6 bolts. The center lock system is commonly used with performance road bikes.
Post mount disc brakes require a post mount adapter, while flat mount disc brakes do not. Post mount adapters are more common and are used for carbon mountain bikes, while flat mount interfaces are becoming the norm on road and gravel bikes. All disc brake adapters are adjustable for rotor size, though. Road bikes usually use 160mm rotors while mountain bikes use rotors that are 180mm or 200mm.

Disc brake mounting interfaces that are helical splined

A helical splined disc brake mounting interface is designed with a splined connection between the hub and brake disc. This splined connection allows for a relatively large amount of radial and rotational displacement between the disc and hub. A loosely splined interface can cause a rattling noise due to the movement of the disc in relation to the hub.
The splines on the brake disc and hub are connected via an air gap. The air gap helps reduce heat conduction from the brake disc to the hub. The present invention addresses problems of noise, heat, and retraction of brake discs at the release of the brake. It also addresses issues with skewing and dragging. If you’re unsure whether this type of mounting interface is right for you, consult your mechanic.
Disc brake mounting interfaces that are helix-splined may be used in conjunction with other components of a wheel. They are particularly useful in disc brake mounting interfaces for hub-to-hub assemblies. The spacer elements, which are preferably located circumferentially, provide substantially the same function no matter how the brake disc rotates. Preferably, 3 spacer elements are located around the brake disc. Each of these spacer elements has equal clearance between the splines of the brake disc and the hub.
Spacer elements 6 include a helical spring portion 6.1 and extensions in tangential directions that terminate in hooks 6.4. These hooks abut against the brake disc 1 in both directions. The helical spring portion 5.1 and 6.1 have stiffness enough to absorb radial impacts. The spacer elements are arranged around the circumference of the intermeshing zone.
A helical splined disc mount includes a stabilizing element formed as a helical spring. The helical spring extends to the disc’s splines and teeth. The ends of the extension extend in opposite directions, while brackets at each end engage with the disc’s splines and teeth. This stabilizing element is positioned axially over the disc’s width.
Helical splined disc brake mounting interfaces are popular in bicycles and road bicycles. They’re a reliable, durable way to mount your brakes. Splines are widely used in aerospace, and have a higher fatigue life and reliability. The interfaces between the splined disc brake and BB spindle are made from aluminum and acetate.
As the splined hub mounts the disc in a helical fashion, the spring wire and disc 2 will be positioned in close contact. As the spring wire contacts the disc, it creates friction forces that are evenly distributed throughout the disc. This allows for a wide range of axial motion. Disc brake mounting interfaces that are helical splined have higher strength and stiffness than their counterparts.
Disc brake mounting interfaces that are helically splined can have a wide range of splined surfaces. The splined surfaces are the most common type of disc brake mounting interfaces. They are typically made of stainless steel or aluminum and can be used for a variety of applications. However, a splined disc mount will not support a disc with an oversized brake caliper.
