“Don’t work hard, work smart” – this saying definitely comes true when you’re doing something as mundane as changing the wheels from a vehicle. On top of it, if the bolts and nuts are stuck hard, the work becomes much more grueling.
This is the type of situation when a torque multiplier comes in handy. There are few safe alternatives to using torque multipliers when it comes to handling tight bolts and nuts.
So, exactly how to use a torque multiplier? Well, you’ve to go through this short and sweet all-in-one article to learn all about this invaluable toolkit.
What Is a Torque Multiplier?
Basically, torque is a measure of the twisting force that causes rotation about an axis. It is the product of the force and distance from which the force is applied.
Torque multipliers increase this product of force and distance by reducing the force applied and increasing the distance. Thus when an operator uses this tool, they don’t need to work harder. It gives the user a great mechanical advantage by requiring less physical strength.
How a Torque Multiplier Works?
Comprehending the mechanism of a torque multiplier will make you appreciate this tool even more.
We all know, the output power of anything cannot be greater than the input power. So, there has to be some other way to manipulate this rule and increase the effectiveness of the output power.
In the case of rotation, this can be done by reducing the number of output turns compared to that of input turns but at the same time increasing the applied force instead. In this way, the tool is of a fairly basic gear arrangement.
A torque multiplier consists of two gears where the center of one gear revolves around the center of the other. There is a carrier that connects these two centers. It rotates to carry the planet gear around the sun gear forming an epicyclical gear train. In each of the gearing stages, the applied torque is multiplied by the bolt.
As a result, even the most stuck hard bolt starts to rotate ever so slightly, making the most challenging job more manageable.
Different Types of Torque Multipliers
There are three major types of multipliers based on their mechanism, namely manual, hydraulic, and pneumatic torque multipliers.
Manual Torque Multiplier
This is used for everyday usage for fastening or loosening operations. They are typically lightweight and portable.
Pneumatic Torque Multiplier
On the other hand, This uses compressed air power for applying precise torque.
Hydraulic Torque Multipliers
How to Use a Torque Multiplier Wrench?
Although the basic goal for the usage of any toque multipliers is the same, there are few differences in how they’re used. This article will discuss the manual torque multiplier that’s most often used in everyday lives by DIYers and professionals. It is known as torque wrenches.
The method of using these torque wrench multipliers is the simplest among all. Just follow these simple steps:
Step 1 – Get the Right Socket
The most important thing is picking the socket that fits perfectly with the nut and the torque wrench.
Step 2 – Attach the Multiplier
Now attach the torque multiplier to the other end of the socket. This end of the multiplier will rotate slowly and, in turn, rotate the socket.
Step 3 – Put a Stand Under
It is better to put a stand under the torque multiplier to keep it straight with the nut of the vehicle. Although you can keep holding it with your hands.
Step 4 – Attach the Inching Drive
Next, you need to put some strain on the other end of the multiplier, and for that, you have to attach an inching drive to it. It is better if the inch drive is a bit long, for it will require less force.
Step 5 – Rotate
Rotate the inching drive a few times, and you’ll notice the stuck nut is being loosened little by little. When it is loose enough, remove the multiplier, and you’ll be able to do the rest of the work with a simple wrench.
Torque Multipliers have revolutionized the way of working with heavy-duty and stuck nuts and bolts. Learning how to use a torque multiplier helps one immensely in reducing a great many workloads.
