Aluminium Couplings is versatile and is a renowned material for various industries. Consequently, it possesses these distinctive functions:
- The aluminium coupler detaches efficiently for convenient repairs and maintenance.
- It must be uncomplicated to unite the shafts and must keep them adequately.
- Coupling must join shaft units manufactured separately for different purposes, such as a motor shaft and a generator shaft.
- Ideal to be an aid for the misalignment of connected shafts.
- To permit mechanical flexibility, such as in the matter of flexible coupling.
- Lessening and absorbing transmission of shock freight from one pole to another
- Rendering protection against overloads
- To alter the vibration characteristics of rotating equipment whenever required.
Generally, there are two main classifications of the aluminium coupler. Namely,
Rigid Aluminium Coupler
An aluminium coupler is beneficial to join two shafts in symmetrical alignment.
It composes two flanges with hubs, one keyed to the driving shaft and the other to the driven shaft. Two flanges utilize robust bolts to keep in place.
There are three types of rigid aluminium coupler
- Sleeve or muff coupler
- A split muff or clamp coupler
- Flange Coupler
Flexible Aluminium Coupler
An aluminium coupler linked two shafts holding both sidewards and angular misalignment.
The aluminium coupler structure is comparable to a rigid coupler. However, compared to a rigid coupler, it has a flexible feature.
The flexible element is the rubber bush is equipped with brass lining to evade unwanted wear. These rubber bushes grip the misalignment between the shaft.
There are three main types of flexible aluminium coupler shaft:
- Bushed pin-type coupler
- Universal coupler
- Oldham coupler
Moreover, flexible aluminium couplers-both rigid and flexible aluminium couplers possess some of these salient benefits:
The helical trimming of flexible couplers causes them to act as a spring in the X Y and Z linear axis except in the rotational axis.
That means you won’t get more backlash.
The aluminium coupler is an instrument that transfers power and torque.
Couplings do not allow disconnection of shafts during operation.
Yet, some couplers have torque limits that can drop or disjoin when some torque limit overextends.
Through meticulous selection, structure, and care of couplers, significant conserving is possible in fewer maintenance expenses and downtime.
It can guard the driving and driven shaft components against damaging effects because of misalignment, impulsive shock loads, and shaft expansion or vibrations.
In many applications, you need to choose the proper type of aluminum coupler.
Determining what kind of coupling helps you achieve a satisfying and efficient project.
When selecting a suitable aluminum coupler for your applications, here are some factors to consider.
Thread Type
Identifying the exact thread type is essential. Multiple types of aluminum couplers suit your applications.
Here are some types:
NST or National Standard Thread
NPSH or National Pipe Straight Hose
NPT or National Pipe Tapered
Thread Gender
Thread genders are divided into three types, which includes:
Female Coupler – is designed with internal threads that receive male coupler.
Male Coupler – is formed with external threads. It is ideally used for applications where discharging water is required.
Ungendered – You can connect even two parts of this gender without using threads.
Compatibility
Consider the list below to know the aluminum coupler types and threads compatibility.
| Thread Type and Gender | Compatible with: |
| NH/NST male | NH/NST female |
| NH/NST female | NH/NST male |
| NPT male | NPT female, NPTF female, NPTSH female |
| NPT female | NPT male, NPTF |
| NPSH male | NPSH female, NPSM female |
| NPSH female | NPSH male, NPT, NPTF, NPSM |
Coupling Sizes
Lastly, if you have already defined the thread types and gender, ensure the appropriate size for your specific applications now.
The aluminum coupler sizes range is about ¾ inches to 6 inches in diameter.
To find out your fitting size, measure the internal diameter of the male coupler.
It helps determine what aluminum coupler dimension you need.
