Gearbox couplings | types |working



Hello readers, welcome to all of you in another new post, do you know what are gearbox couplings and how many types are? Know what is Gearbox Coupling


gearbox couplings

Gearbox Coupling is a connector that connects two shafts together so that power transmission can be done. Gear couplings are known for high torque power transmission. Why are couplings used for s, there are other ways to connect two shafts, such as welding, or a gearbox can also be used, but let us tell you that there is a risk of shaft damage due to welding. increases, as well as high torque transmission, is not possible, the two shafts do not connect properly, which increases the chances of misalignment No problems as such and both shafts can be easily disassembled if needed which is difficult with welding Gearbox couplings allow easy high torque transmission

Working on Gearbox Couplings

If understood in simple language, the main function of gearbox couplings is to connect two different shafts together. Gearbox couplings are used to connect the edges of these two shafts. When one shaft rotates, it also spins the other shaft, and it also protects against road shocks that lead to high torque transmission

types of couplings

There are two types of couplings

Jaw Couplings

Jaw Couplings is such a mechanical device, it is used for the transmission of torque in small quantities, and flex material is used to make them. It is made, which enables high power torque transmission.


gear couplings

A hub is used to make gear couplings and external gears are used in both the sleeves and bolts are used to connect the sleeves and crown gears are used in the upper side. In this, the gear ratio is used to transmit power from one shaft to another, which is about 1:1. Gear coupling is used for the transmission of torque in high amounts to avoid friction in it. Lubricant is used, this type of coupling is used in heavy vehicles.

magnetic couplings

Use of Magnetic Couplings: This type of coupling is mostly used in an electromagnetic clutch, in which electromagnetic is used for power transmission, which causes torque transmission.

Universal Couplings, Hook Couplings

Universal couplings use a universal joint, also known as hook coupling. It is used to supply torque transmission in rotary form and to interconnect non-parallel alignment shafts. The shafts are called the driving shaft and the driven shaft, the, when driving shaft which we also called the input shaft, its rotation is simultaneous with angular speed, and vice versa, the driven shaft which is also called the output shaft, is angular speed and varies with you. Must have understood that the angular speed of two shafts is not the same.

Construction of Universal Coupling

In this, forks are made at one end of the driving shaft and drive shaft. Both the forks of the shaft are connected to the centerpiece. The centerpiece is usually of spherical shape but they are also made in cross and square shape if needed, these fork centers are connected at the right angle on the piece, in which the fork connection is used between the two shafts and the fork connection itself gives motion to both the intersecting axes shafts. or power is delivered to the front axle

double hook couplings

These couplings are also almost similar to hook couplings, but in this, two universal joints are used and these two joints are connected to each other through intermediate shafts, they are always intermediate to obtain uniform angular speed and constant velocity ratio. remains at an equal angle with the shaft and the forks of the intermediate shaft rotate uniformly

Rigid Couplings

In this type of coupling, rigid couplings are used to connect two shafts, this is a kind of very rigid coupling, it is used at the place where the access of both the shafts is collinear, which means two Shafts should have the same access, in this, the movement between both the shafts is negligible, in this two rigid are used which act as a single shaft, thus

Wire couplings are mostly used in vertical form like in turbines etc.

Construction of Rigid Coupling

This type of coupling is normal to see and their pricing is also very high because they are used in connecting parallel shafts, so if misalignment occurs in the shaft, then this coupling does not work properly or does not work at all. There are three types of rigid couplings which are as follows

sleeve couplings or muff couplings

Sleeve couplings are also a type of gear coupling, in which a material piped device is used, which looks almost like an engine cylinder and it connects the drive shaft and the drive shaft, which the shafts are connected by means of bolts. It is known that there is a high torque transmission without loss of power, this type of coupling is also used for the transmission of low torque and is also better in shaft alignment.

In this type of coupling, the transmission of power is first from the driving to the key and then through the power key to the sleeve, and then to the driven shaft. This type of shaft is mainly used for small diameter shafts whose diameter is about 65- 85 mm This type of coupling is not able to tolerate any kind of jerk and vibration, so where this type of coupling is used, it should be vibration free and jerk free

clamp coupling

This is a modified form of the muff coupling, it also uses sleeves, and these sleeves are divided into equal two halves, which it is also known as split muff coupling, both of the sleeves are interconnected through split nut bolts. are assembled and the key is used between the sleeve and the shaft so that the connection between the sleeve and the shaft is maintained, which is very important for torque transmission. transmits to the second shaft

flange couplings

From a structural point of view, flange couplings also look almost the same as sleeve couplings. And it is almost the same, but in this, the flange is used around the sleeve, meaning the flange is used to connect the two shafts, this type of coupling is also not able to tolerate jerk and vibration.


Flexible Couplings

Gears are used in gear couplings, and gear arrangement is used, you all know that even if the alignment of the shaft is done correctly, the shaft moves due to vibration, this type of coupling is similar to the flange coupling but in this Rubber, the bush is used along with the flange, which reduces the vibration in the shafts and also reduces the damage in the shaft.

split muff coupling

In this type of coupling, two cylinder-shaped pieces are joined together through bolts, it is also commonly called compression coupling.

Oldham coupling

Oldham couplings are used to connect two parallel shafts, two rotating shafts have eccentricity, and they have misalignment, between these two shafts, a driven flange, and drive flange are used and between these flanges, there is a rectangular slot. are cut and these slots connect to each other at right angles tongs are used in these slots. When the shaft is rotated, the tongs slide over the flange.

Apart from this, there are some other couplings which are as follows


Grid Couplings
JXL Pin & Bush Couplings
Tire Couplings
Torsional Couplings
All Steel Gear Couplings
Bellows Couplings
Hydrodynamic Fluid Couplings

Disc Couplings

S-Flex Couplings
Disc Couplings
Claw Couplings
Magnetic Couplings



Q-What is a coupling gearbox?

Ans- A gearbox coupling is a machine used to connect two separate shafts. A shaft coupling is used to transmit torque to the transmission system. Due to this, there is a high torque transmission, there are many types of it, and

couplings are used a lot in automobiles.


Q-What are the types of coupling?

Ans- There are many types of couplings and couplings are designed in many ways such as Jaw Coupling, Gear Couplings, Magnetic Couplings, Magnetic Couplings, Universal Couplings, Hook Coupling, Double Hook Coupling, Rigid Couplings, Sleeve Couplings or Muff Couplings. There are many types of couplings, such as clamp couplings, flange couplings, flexible couplings, etc.

Q-What is the purpose of coupling?

Ans- The main function of gearbox coupling is to transmit high torque without loss of power,

as well as to absorb jerks and vibrations.
