Are you curious about How Chainsaw Works?
Moreover, do you want to know how to operate a chainsaw smoothly?
Undoubtedly, the main concern related to chainsaws is the uncertainty of what goes on inside it. Apart from this, people also face problem in the calibration, power, maintenance and simply even in How Does a Chainsaw Work.
We are here to make things easier for you by letting you know how it actually works.
How Chainsaw Works – Know the ABC of Working a Chainsaw
Welcome to the world of a chainsaw:
Let’s Take a Peek Inside the Chainsaw After You Start it:
Before we see how it works, we need to know the components that make it work. They are as follows:
- The engine of the saw.
- A starting mechanism.
- Crank and connecting rod.
- Gear wheels.
- A drive shaft.
- Clutch of the chain.
- Guide Bar.
All these work with one another in coordination to make the saw work.
First things first:
A source of energy is required to run the chainsaw.
1. How Does a Gasoline Chainsaw Work?
Understanding the dynamics of a gasoline chainsaw, one thing is clear that it requires more torque to work as compared to an electric one be it corded or cordless.
Why do I say so?
The following steps take place when you start a gas chainsaw.
- When you pull the starter pulley, the crankshaft gets into motion by rotating.
- That in turn sets the piston moves up and down.
- Obviously, when the piston moves up, there is a vacuum created below it.
- As a result of this, the combustion chamber on the top of the piston is compressed because of the piston hitting the top.
- Now, what the air filter does is that it throws in air in the vacuum created.
- On the other hand, the fuel comes in from the fuel tank.
- Here, the air and fuel mix.
- From here, this mixture fills the crankcase below the piston.
- While all this happens, the piston starts to make its journey downward.
- This pressurizes the fuel mixture to get combustion chamber on the top.
- This up and down motion goes on for a second or two and the temperature of the mixture is increased because of the compression and the addition of more mixture.
- Once it reaches a maximum level, a spark occurs.
- This is the first stroke of the gasoline chainsaw.
- Now, the piston moves downwards and opens the exhaust port of the saw.
- The new mixture enters and the gases of the burnt fuel escape.
In this way, the process starts all over again.
And the amazing thing is:
That all of this happens within seconds.
A thing to notice here is all of this happens when you start your chainsaw for the first time in the day. If you are working after a short period of time, the spark plug will face less trouble to reach the temperature it needs to operate.
2. What Goes into Making an Electric Chainsaw Spin?
On the other hand, if you are going to use an electric chainsaw, an electric current will power it.
What happens is that an electric current goes into the motor of the saw. Furthermore, this motor produces kinetic energy by converting electric energy provided to it.
In turn, the crank and rod uses this energy to produce a rotary motion.
Both the corded and cordless electric chainsaws run on electric power. The corded one needs electricity from a power supply. On the contrary, the cordless ones run on batteries. But, the working mechanism is same for both.
3. Where Does It Go from Here?
From here, the mechanism of both a gasoline chainsaw and electric one is the same.
Can you see a domino effect happening?
From here on, a drive shaft transmits the rotary power to a centrifugal clutch.
4. Why Does a Saw Need a Clutch?
The clutch lets the engine run all the time by disengaging the chain when the blade is not being used. Moreover, it saves the hassle of switching the saw on and off again and again by disengaging the chain.
This is made possible because of the gears that connect the clutch to a sprocket holding the chain.
Last but not the least:
It spins around the steel guide bar that is a steel plate which spits out the dust of the wood as it works.
Clearly, there is so much going on inside the chainsaw!
To sum it all up, now you know for sure How Chainsaw Works. Overall, there are a few simple components explained in this guide like the piston, combustion chamber etc. that work together to make the saw do what it does best.
