FAQs

1.What Is A Universal Joint Coupling?

The universal joint coupling acts as a joint between two main parts of a machine.

Universal joint couplings are used to join two parts that are dependent on each other in terms of their functioning.

The parts which are connected through a universal joint coupling can be inclined or perpendicular to each other.

Universal joint couplings have broad applications in automobiles as well as various mechanics factories.

The main purpose of a universal joint coupling is to transfer angular momentum between two parts.

Universal joint couplings can be manufactured in various sizes and lengths depending upon the requirements of the machine.

The features, as well as nominal torques of your universal joint coupling, can vary from machine to machine.

Universal joint couplings are also known as cardan shafts.

LYNNUO universal joint couplings are the best and more durable than any other company’s universal joint couplings.

2.How Are Universal Joints Made?

Universal joints are composed of two revolute joints with intersecting as well as perpendicular axes.

When the connection is made using universal joints, the shafts start rotating around the revolute joint with its axis perpendicular to the rotational axis of the shaft.

This process allows the transformation of rotatory motion between the shafts

It is important to note that a universal joint is not a joint with constant velocity.

The velocity of the universal joint keeps changing.

If the input velocity of a shaft is rotating at a constant level then the output velocity of the shaft can be varying or oscillating.

The amount of oscillation or variation in the shaft depends upon the whole amount of alignment between the shafts.

3.Why Do We Use Universal Joint Coupling?

There are various machines in various industries for which the working function depends upon two main parts.

The first main part is the driving component,  which is mostly known as a shaft while the other part is driven, also called the shaft.

On the other hand, there is a driving shaft that works through the functioning of the driven part.

Both the parts are dependent on each other.

In order to connect or join these parts, to make them work perfectly, we use universal joint coupling.

It is very interesting to note that the universal joint couplings act as a permanent shaft between the two main parts of a machine; the driven shaft and the driving shaft.

It doesn’t matter whether the two parts are inclined to each other or not.

Universal joint couplings are also used due to the following properties :

• Highly durable
• Easily replaceable
• Have the simplest structure
• Simple working mechanism
• Connect non-parallel shafts
• Can transfer a larger amount of torques

4.How Does A Universal Joint Coupling Work?

The working process of a universal joint coupling is not that much complicated.

There are also essential components of universal joint coupling which make them work more smoothly.

These components are :

• Flange York
• Cardan joint

The universal joint coupling works in a way that two flanges yorks are very close to each other.

The purpose of the Cardan joint is to pass through the holes of two flange yorks,  and establish the connection between this two flange yorks.

Due to this connection establishment, when one flange york is rotated, the other flange york is rotated itself due to the presence of hinges.

The purpose of flange yorks is to connect the two main parts of the machine.

As the flange york is present at both sides, the driven shaft can be connected at one side while the driving shaft can be connected at the other side.

In this way, the rotatory motion will be transmitted between the two main parts of the machine.

6.How To Select A Universal Joint Coupling?

Selecting the appropriate and best universal joint coupling can be an easy process for you if you know which factors to consider while choosing or selecting a universal joint coupling for your machine.

There are few factors that can affect the selection process for your universal joint couplings.

These factors are listed as under :

• Total Calculated Torque
• Speed of rotation
• Life of Bearing
• The maximum amount of Bending Moment
• Angle of Misalignment

In order to calculate the total torque to select the best universal joint couplings for your machine, you can use the following formulae :

The meaning of each term is explained as under :

Tc = Calculated Torque, N•m;                                  T = Theoretic Torque, N•m;                                                                        PH= Driving Power, hp;                                            Pw = Driving Power, kW ;

n = Operating Speed, rpm；                                    K = Service Factors (See Table )

Secondly, you have to calculate the life of the bearing of your machine in order to select the best universal joint couplings. The bearing life relies upon the misalignment angle, speed of rotations, and the transmitted torque.

The best universal joint coupling is the one that can help you to achieve a bearing life of more than 5000 hours.

You can find the bearing life as under :

In the case of rotational speed, if it is less than 300rpm then you don’t need to worry about that.

On the other hand, if the diameter of your joint is less than 390mm then you can check the rotational speed in addition to the bearing life as well as the calculated torque as under :

The formulae for misalignment angle, as well as the bending moment, are also given below in the figures.

You can use these formulae to find out your exact requirements :

7.How To Install A Universal Joint Coupling?

In order to install your universal joint couplings, you need proper guidance from the manufacturer of your universal joint couplings.

In the case of LYNNUO universal joint couplings, you will get a separate guidebook for your installation process of universal joint couplings.

You have to follow the given easier steps to achieve the installation of your universal joint couplings :

• First of all, you have to raise your universal couplings in a horizontal position with the help of nylon ropes.
• Secondly, you have to make sure that the forkhead at both heads of the spline sleeve and spline shaft are in the same phase.
• Then the next step is the cleaning process.

You have to clean the flange mounting surface.

• Then the next step is to put bolts in the flange from the driven shaft side and then tighten.
• Now you have to use bolts of grade 10.9 high strength and nuts of grade 10 for the purpose of flange connection.
• Now you have to apply MoS2-free grease spray on the threaded portion of bolts.
• Now, the next step is to use a torque wrench which will help you to tighten the bolts.
