How your Electric Screwdriver Power Tool Works?

We all know without a screwdriver, we’d not be able to do anything that involves dealing with machinery whether at home or at the workplace. And electric screwdrivers happen to be the most convenient screw driving solutions that we have at present times.

Electric screwdrivers are used everywhere in a variety of situations. Electric screwdrivers are a compact piece of tech that is neatly put together and work like a charm. They are essentially a set of batteries, motors, gears and a switch packed into one extremely well-designed power package.

If you’re looking for electric screwdriver suppliers, then websites such as www.sumitron.com is the place to go. They have all sorts of electric screwdrivers and depending on your need, you can have them in bulk quantities as well.

Let’s have a look inside the design of an electric screwdriver and see how it works.

On taking off the external body, you’re immediately faced with the following components.

a.An electric motor

b.A dual planetary gear system

c.A simple rocking mechanism for chuck

d.The chuck that holds the screwdriver together

e.A rechargeable battery and

f.A switch to operate the mechanism

All parts have a specific function. Let’s have a deeper look into their working mechanism.

The Battery

The battery serves as the powerhouse that keeps everything running. A simple DC voltage output rechargeable battery is used that is connected to the electric motor via the power switch.

The Switch Block

The switch clock serves two important roles in a screwdriver.

1. It prevents electricity from flowing from the battery to the motor.
2. It supplies power to the either polarity of the motor and enables the user to run it in clockwise or anti-clockwise direction as desired.

The Electric Motor

The electric motor used is a typical DC – electric motor. The size may vary with the screwdriver’s size. The motor provides rotational motion to the screwdriver and is connected to a 6 tooth gear which fits into the centre of the planetary system.

The Gears

The gears do the job of taking motion from the rotating pinhead of the motor to the screwdriver. It is the heart of any electric screwdriver. The motor used in a screwdriver is relatively weak with a high RPM, but when paired with this gear system, it can easily be used to collect strength and drive a screw into wood.

The dual planetary gear system has a very high reduction ratio. For every 56 rotations of the motor axle, the chuck turns once. This means a very slow chuck movement as compared to the motor but with ample amount of torque. In order to stop the motor from spinning, 56 times more force is required thanks to the wonderful dual planetary gear system that comes in most of the electric screwdrivers.

If you are looking for the right electric screwdriver, there are plenty of websites you can visit. There are a large number of electric screwdriver varieties present on sites such as www.sumitron.com.
