Chain Coupling: Attributes, Designs And Specifications.

Chain couplings in very simple description is composed of a flexible three-piece that are all having a flexible shaft. These shafts are flexible couplings which are used in connecting both the driven shaft and the driving shaft in any form of mechanical energy transmission. This couple with flexible shaft are all used for solving the often encountered problem of misalignment between shafts.

 

Bellows, grid, beams, Schmidt, Oldham, gear and disc are just a few of the existing styles of couplings, amongst a host of others.

 

Specifications and attributes

● Parallel misalignment

This is also known as lateral offset, it stands for the highest tolerable distance of shaft alignment that may occur along the axial dimension which can be tolerated by the coupling.

 

● Coupling diameter

This term is used to refer to the total diameter of each coupling

● Gap

A particular gap to be maintained between the coupled shaft Is referred to as a gap.

 

● Bore size

It is also known as diameter.  It is used to describe the diameter size of a particular coupling bore, which is able to accept the commenting shaft.

 

The sizes of the bore on all the sides of each coupling depend on the type of the model. They may be of similar or different sizes.

 

● Overall length

This is the measurement taken from one end of the length to another. This is usually measured starting from the extremes of both extreme faces of each coupling.

 

● Allowable speed

This refers to the highest revolution per minute (rpm) at which the coupling works.

 

● Highest rated torque

It is the highest rating for the coupling of each rating for the peak torque.

 

● Shaft coupling and fastening method

This is the method whereby the coupling shaft is being attached to the driven shaft.

 

● Maximum RPM

The maximum speed for the coupling is often times usually stated by the Manufacturer.

 

● Product size

The sprocket and coupling chain must be of an exact match. For example, a 8020 by a 1.5-sprocket will nicely fit into a 1- ½  inches diameter. Shaft. Also, it will couple with a coupling chain of about 8020.

Applications

They can be used in a series of application as stated below;

● They are often used in low as well as  moderate speed or even a high torque uses.

● They are also used in line-shaft couplings, especially in live roller conveyors. In this case, the plastic chain is responsible for providing a coupling solution without lubrication that doesn’t need either covers for the retention of lubricant nor even coupling guards. This is because the smooth external surface of the chain doesn’t have any catch hazards.

 

Overall, they are easy to install and are sturdy and considered to be fairly rugged.

 

Coupling design

A typical coupling design consists of two identical sprockets, one on the left and another on the right. They are connected through acetal plastic chains. Unlike roller chain coupling which requires lubrication, acetal plastic chains couplings doesn’t need any lubrication, and for this reason, they dispense with their covers over.

 

A downside to plastic chains is that it transfers less torque than roller chains but makes up for it with its eco-friendly aspects.

 

In environments with no tolerance for grease spills, where they are considered as contaminants or where they might lead to accumulation of debris and atmospheric corrosion is already a problem, plastic chains are your best bet.
