Cardan Shaft-The Ultimate FAQ Guide

Are you operating a machinery business? Do your machines lack efficient power transmission?

The solution is simple:

You need a Cardan Shaft for proper power transmission within your machines.

This FAQ guide will solve all your queries and allow you to select the right Cardan Shaft for your business. Let’s get started.

What Is A Cardan Shaft?

A Cardan Shaft is a mechanical Shaft that transfers power between components of a machine.

It is a bridge between two mechanical components that maintain power flow between them.

As it is used in heavy machinery, it is metallic and may be composed of:

• Steel
• Chrome
• CrMo

In addition to these, many strong metallic alloys like stainless steel and forged steel are also used to compose a Cardan Shaft.

How Does The Cardan Shaft Work?

A Cardan Shaft works with high-pressure intensity to transmit power from one machine component to the next.

The Cardan Shaft is attached with two flanges on each side, further connected to the pressure receiving output box.

When the flanges rotate, they provide torque power to the receiving end.

The gear output box receives and transfers pressure further in the machine.

This transfer of pressure instigates power which drives the pump.

As the pressure increases, so increases the power.

What Are The Main Parts Of The Cardan Shaft?

Following are the main parts of the Cardan Shaft:

• Cross Universal Joint

It is a kind of coupling or, as the name shows, a joint that connects two axles commonly in a Shaft.

• Flange

Flanges are the most important part of Cardan shafts.

They are points that rotate to generate torque and are present on both sides of the Shaft.

• Flange Yoke

The flange yoke is the part of a Cardan shaft that connects the flanges for power transmission.

What Are The Main Applications Of The Cardan Shaft?

Cardan Shafts have widespread applications in mechanical industries such as:

• Automotive Industry

Cardan Shafts are widely used in automobiles such as trucks, forklifts, and other loading vehicles.

• Rolling Mills

The machinery in rolling mills also requires efficient power transfer from multiple machine components.

For this, it is also home to multiple uses of Cardan Shafts.

• Paper Production

Heavy machinery is used in the papermaking process.

They, too, require Cardan Shafts of varied sizes at numerous points in the production machines.

• Crane System

Cranes are commonly used for moving high weights in construction and engineering.

They also use Cardan Shafts for movement with power transmission.

• Pump Machinery

Pump machinery widely used in water recycling and other processes needs something to drive the pump.

Cardan Shafts provide this energy.

What Is The Working Principle Of A Cardan Shaft?

A Cardan Shaft works on the high-pressure principle and inertia.

When pressure is provided from one end, the Shaft rotates, creating a torque.

The strength of this torque further transmits the power to further components of the machine.

The Cardan Shaft works as a torque carrier and is subjected to torsion and shear stress principles.

These are equal to the input and output power; otherwise, the whole inertia of the machine becomes imbalanced.

What Are The Types Of Cardan Shafts?

Cardan shaft has the following types:

Light Duty Cardan Shaft

It has 58 to 225 mm flange diameter and is commonly used in:

• Paper machinery
• Pumping machinery
• General machinery
• Test machinery

Long Series Cardan Shaft

With a flange size of 160 to 390 mm, it is a low inertia Cardan Shaft.

The long series Cardan Shaft is typically used in:

• Pumping equipment
• Marine drives
• Papermaking machines
• Down coilers

Medium Cardan Shaft

Medium Cardan Shafts have 160 to 390 mm flange size and are used in:

• Cranes
• Rolling mills

• Straightening machinery

Heavy-Duty Cardan Shaft

600-1200 mm flange size, the heavy-duty Cardan Shaft is used in:

• Plate mills
• Crushers
• Tube piercers
• Windmill test machinery

Hollow Penetration Cardan Shaft

Hollow penetration Cardan Shaft has 225-490 mm diameter size and is usually used in:

• High beam mills
• Bar mills

Ultra Short Cardan Shaft

The flange size of ultra-short Cardan Shaft is 275-405 mm and is used in:

• Marine drives
• Locomotives
• Windmills

Other than these truck Cardan Shafts, roller Cardan Shafts, and dust cover Cardan Shafts are also widely used in the mechanical engineering industry.

How To Choose The Right Cardan Shaft?

To choose the right Cardan Shaft, you must consider the following factors:

• Functionality

You must check out the functionality that is the purpose of a Cardan Shaft.

Either it was built for drive trains, automobiles, or paper machinery, it all impacts its functional patterns.

So determining the functionality is the first and foremost thing.

• Structure

The right structure or construction of a Cardan shaft must be taken into account before purchasing.

You must check out the distance of the axle and if it will fit inside your target machinery.

The size of joints should also be appropriate for fitting and rotation.

Overall the assembly should have a perfect structure for your target purpose.

• Material, Quality

The material used in your Cardan shaft composition must be high quality.

Following materials are considered best for manufacturing Cardan Shafts:

• Steel
• Chrome
• Forged steel

Any other material-made Cardan Shaft is not preferable.

• Rotational Speed

You must take the rotational speed of the Cardan Shaft into consideration.

This is because it will be transmitting power in between components.

If it is too slow, it will not drive your machine.

If it is too fast, the machine will burn out.

In case you find all of the above okay, you must go back to your requirement.

For instance, if you are in the automobile industry, you need to consider the appropriate size for the making.

After this, you need to test the Cardan Shaft to note the following things:

• If there is too much noise.
• If there is oil leakage from any point of the assembly.
• Does it knock in case it is inside an automobile?
• If the Shaft’s vibration is normal when the speed is increased.

If this entire checklist is marked, you can proceed to buy your Cardan Shaft.

How To Maintain The Cardan Shaft？

You can maintain the Cardan Shaft using these three tips:

• Oil The U Joints

The Cardan Shaft has a rotational action that can generate a lot of friction.

Friction causes irreparable damage to a machine to avoid oil the joints of the Cardan Shaft.

Regular lubrication, it is recommended to inject oil once a week, and once a day under high-temperature conditions

• Avoid Water Contact

Exposure to water can rust the parts of the Cardan Shaft quickly due to its metallic.

Rust also disrupts the smooth running of the Shaft as it is stuck.

So avoid contact with water at all costs. Lynnuo usually adds an inside slide cover on the spline shaft.

• Balanced Use

If used excessively, your Cardan Shaft may burn out.

If used too little, it can become jammed.

So always use your Cardan Shaft in intervals with short breaks in between for best performance results.

These three tips efficiently multiply the life of a Cardan Shaft manifold.
