What torque is needed for an electric screwdriver?

Gasoline engines do not differ in the largest twisting moment. The torque of the gasoline engine reaches at a speed of at least 3-4 thousand of its greatest value. Rpm. However, the gasoline engine will quickly be able to increase power and spin to 7-8 thousand. Rpm. With such ultra.High speeds, the power increases significantly.

The diesel engine does not differ in high speeds. This is usually 3-5 thousand. Maximum maximum, and then he loses gasoline motors. However, the torque of the diesel engine is much higher, and it becomes accessible very quickly, almost from the idle.

As a specific example, you can recall the tests of two engines from Audi. One diesel: 2.0 TDI with a capacity of 140 l.With. And torque 320 N.M, and the second gasoline: 2.0 FSI with a capacity of 150 l.With. And twisting a moment 200 N.M. According to the results of the control run in various modes, it turns out that the diesel is as much as 30-40 liters.With. More powerful than a gasoline engine in the range from 1 to 4.5 thousand. Revolutions. Therefore, it does not work only to look at horsepower. It happens that a motor with a smaller working volume, but with a high torque, shows itself much more dynamic than an engine with a large working volume, but low torque.

In the technical characteristics that are indicated for each car and its engine, the indicator of the maximum torque is always indicated in combination with the value of revolutions, in which such torque can be achieved. It is usually considered: if the maximum torque can be reached at revolutions up to 4.5 thousand. Rpm., then such an engine can be called low.Speed; and if more than 4.5 thousand. About/min. Then high.Speed.

With a small number of revolutions, a small amount of air-fuel mixture per unit of time enters the area of ​​combustion, so the torque and power are small. Increasing the speed, the amount of fuel-air mixture (and after it the power and torque) increase. Reaching significant parameters, power begins to decline due to mechanical losses for friction of mechanisms; inertial losses; from insufficient air injection (called oxygen starvation).

torque, electrical, screwdriver, device

For reasons of ensuring the maximum amount of incoming air into the combustion chamber, even at minor engine speeds, turbocharged boost systems with electronic regulation are used. Using such turbocharging systems, it is possible to ensure uniform characteristics of the torque in the wide engine speed.

Incorrect selection of packaging

The cheapest packaging option is cardboard. But it will not last long. The packaging will tear. Then there will nowhere to store an electric screwdriver. For an amateur who bought a tool for an apartment or home, this will not be a problem. But the professional master needs a case. You should choose it in a plastic suitcase. It is convenient for storing and transporting. There are thoughtful modular cases. They are attached to each other, can be transported on a wheelbarrow. These are optimal plastic suitcases for professionals like L-BOXX or METALOC. Cases with such a system are often used by popular tool manufacturers: Metabo, Bosch.

“ TORQUE SCREWDRIVERS “ An Electrical Code Requirement( NEC Article 110:14 )

This tool is available in various modifications, which can be classified as follows:

  • Battery screwdriver. Designed only for working with fasteners like screws, screws, screws. Widely used on assembly conveyors.
  • Gaikovyrt. Created to work with bolts and nuts, is used on assembly conveyors, car services and other enterprises.
  • Drill-shurovyrt. Designed for drilling, there is a low speed mode for twisting and twisting fasteners with a slot under a screwdriver.
  • Shurovyrt. It is used to unscrew and twist fasteners with cruciate heads, as well as for drilling holes of small diameter in wood, plastic, non.Ferrous metals and other soft materials.

For the use of screwdrivers does not require any special skills. Even a small child easily begins to twist and twist screws, if he showed him how to do it correctly. As soon as the Drill-Shurovyrt appears among home tools, the need for nails and hammer immediately decreases. Particularly popular are models working from batteries. They do not need an electric network, so they are mobile, autonomous, independent.

All screwdrivers are divided into two groups: professional and household. The main differences are the price, the capabilities of the tool and the duration of continuous work. Professional models are more resilient, but not so functional, have more powerful batteries that are much less likely to require charging. A professional tool is made of strong materials, with high quality and designed to work in “Spartan” conditions. It has a torque higher than that of a household tool, therefore it can screw the screws into more durable and strong materials.

And what is Newton-meter?

Again, if you use a quote from Wikipedia, then “one Newton-meter is equal to the moment of strength created by a force of 1 N, relative to a point located at a distance of 1 m from the line of action”.

Regarding the electric screwdriver I will explain this as follows. The cartridge of an electric screwdriver has a axis around which it rotates. Take an electric screwdriver and place its rotation axis horizontally

torque, electrical, screwdriver, device

Then we take a metal rod of a Mr.-shaped shape, in which one of the sides has a length of 1 m, and the second (no matter how long) will be clamped in the cartridge. So, if the side of the rod, which is 1m, is horizontally and on its opposite from an electric screwdriver, the end is hung with a load weighing 100 g, then we will get a torque that affects the cartridge approximately equal to one new meter. And if you hang, for example, a load of 4 kg, we get 40 nm

And if you hang, for example, a load of 4 kg, we get 40 nm.

Therefore, if an electric screwdriver is stated, for example, that its maximum torque is 40 nm, this means that the engine of an electric screwdriver through the gearbox transfers such a force to the cartridge as if we really collected the above design and hung a load of 4 kg. We will not consider the mass of the rod itself.

This is what the torque of an electric screwdriver is.

Well, in conclusion, I must say that the maximum torque is achieved by full pressing the start button. In addition, at two.Speed screwdrivers at different speeds, the moment will also be different. At the first, the second less.

Also, screwdrivers have a special regulator with a scale with marks from 1 to 15, 20 or another number (as the manufacturer decides) and the last mark in the form of a drill (in this position you can and should be drilled), which limits the torque. That is, if you install the regulator on one of the numerical marks, then when the moment reaches a certain value of the moment, the electric screwdriver does not twist further, but fades it. But if the regulator is put in the “drill” position, then the electric screwdriver will not fade, but will try to twist what it twists to the last. At the same time, the numbers indicated above do not mean the very moment itself, but simply show how much or less you do it (simply to focus faster at work)

I hope I managed to explain the essence of the torque of the electrical screwdriver. I leave this on this. Until new meetings!

Screw the screw is one of those tasks that arise from nowhere, but with enviable constancy. Correct the distorted cabinet door, hang a mirror in the hallway, attach a shelf in the bathroom. Small household problems, which you need to solve daily. Twist a bolt, screw or self.Tapping screw using a screwdriver. You can, but it does not always work out. Who has tried, knows: the matter is ungrateful, long, and the result is often zero. But you need to quickly and effectively.

Buy an electric electric screwdriver for everyday household work for households is the best way out. Not to mention the fact that he is indispensable in the work of professionals. It is used at construction sites, in repairs and in furniture workshops. Using an electric screwdriver, installation of drywall structures, installation of windows and doors, fastening of skirting boards and furniture assembly is installed.

Choose an electric screwdriver, focusing exclusively on its cost. Gross error. They differ in power and various functions. In order not to be mistaken when choosing, you should carefully study its technical characteristics before buying. The main ones are rotation speed, torque and battery type (in a battery). But to read digital data. Half the age, you still need to be able to orientate what indicators are needed for you and for the planned work.

Using an electric screwdriver for mixing building mixtures: torque

Screwdrivers are used in construction not only for installation, but also for stirring various mixtures and solutions. To do this, a special mixer is inserted into the tool cartridge. In this case, the torque must also correspond to the nature of the work performed. When mixing liquid solutions, you can use small values ​​of rotating force.

However, when acquiring a power tool, it is necessary to choose a rotating action sufficient to work with viscous mixtures. In this case, the professional model of the screw.Vert with manual or electronic control is more appropriate. The presence of a lowering transformer will make it possible to work not only with viscous, but also with liquid mixtures. Due to low voltage.

Having carefully read the article, the user will be able to choose the optimal model of an electric screwdriver for both repair work in the household and various assembly or construction operations in production.

How to choose the right electric screwdriver for the home. Battery screwdrivers

This type of instrument is more widely used. Such devices are obtained from batteries, the capacity and time of charging which can vary significantly.

  • Independence from the presence of electricity and the location of the outlet, which gives freedom of action. Work can be performed at a height, in hard.To.Reach places, and almost in the field, and the wires will not be confused underfoot;
  • The scope of use is wider, which follows from the autonomy and mobility of the tool.
  • Dependence on the level of the battery charge, the need to constantly monitor this parameter and periodically charge batteries. Experts recommend taking a spare battery together with the battery electric screwdriver: while one is charging, the second works. It is preferable to choose batteries that are quickly charged;
  • In power, the battery tool loses to the network. Torque may not be enough to work with solid materials, but there are exceptions here. Professional battery screwdrivers are quite powerful and reliable.

Professionals know that choosing a battery electrical screwdriver is even more difficult than network, because it is necessary to take into account not only directly the functions of the device, but also the features of the battery.

The first thing to pay attention to is the type of battery:

  • Lithium-ion batteries, Li- Ion. This is the most popular and modern type of battery, used everywhere, not only in screwdrivers. Of the advantages, low weight, sufficient power, lack of memory effect, a large resource of charge/discharge cycles (about 3,000 or more), high charging speed. Of the minuses is a relatively high cost, so this is a good option for constant, but not one.Time work. Such a battery is not designed to work in the cold. In order for the battery to serve as long as possible, it is better not to discharge it by less than 15% and not charge more than 90%. Service life is about 3 years;
  • Nickel-cadmium, Ni-CD. Have high resistance to low temperatures and voltage surges. On the other hand, they have a pronounced memory effect, so it is better to discharge such a battery completely and completely charge, so as not to reduce its capacity. The battery withstands about 1000-1500 charge/discharge cycles, but it charges for a long time-about 7 hours, so it is better to have a spare battery. The weight of the battery is significant, but it costs the cheaper. Service life is about 5 years;
  • Nickel-metallhydridid, ni-mh. Such batteries become more and more popular, differ in slight weight, low resistance to low temperatures, the effect of memory is unexpressed. A big plus is the minimum self.Discharge, and the minus is the price;
  • Lithium-polymer batteries, Li- Pol. Used in screwdrivers is extremely rare. These are capacious, but not very durable batteries.

Which adapter for a screwdriver is better to take

Oddly enough, your ice screw will require a special adapter that will allow you to connect the drill shaft and the drive shaft of the screwdriver itself. Over, this adapter must have a special pen, for which you will hold on to the left hand, and the screw handle itself will be in the other hand. It is also worth taking care of the insurance of a special limiter, which will not allow the ice discovery to get into the hole if it jumps out of the cartridge. Not every adapter will approach your seeder. It is better to know this moment in advance in the description of the device.

Bosch GSR 18

This model has a slightly more powerful engine than sixty.Three nm, but the weight of the device is noticeably higher. The kit also includes two 18 into batteries with a capacity of two As. Of the minuses, users note the tendency of the cartridge to self.Winding.

Twisting. What is it?

Twisting the moment is an indicator with which you can establish the strength of the load on a screwdriver.

Usually it is in the range of 5 to 10 nm, which allows you to quickly, efficiently and without problems perform work.

Such a load is used for household and semi.Professional models.

She easily dries metal plates, screws large screws, and also works with concrete.

What torque is needed for a good work for good work? This is determined by the purpose of the tool. For example, for a universal device it is better to choose the maximum indicator. This will allow him to work equally successfully with self.Tapping screws and hard materials.

If the screwdriver is purchased for drilling wooden bars, then the cheapest household model with a low torque is also suitable. For example, 400-500 revolutions will be able to easily tighten the self-tapping screw. But for drilling holes in solid surfaces, you need to select the number of revolutions 1200-1300 per minute.

The ratio to the diameter of the screw

During the purchase of a screwdriver, Accent should also be made on the ratio of the diameter of the screw and the speed of rotation. It is quite simple to make it:

  • For a screw of 6 mm, the rotation frequency in the process of twisting will be 10 nm. If the design of the material is very soft or tough, then the frequency will increase to 25 nm.
  • For a screw of 7 mm, torque will be 27 nm for hard surfaces and 11 nm. For soft.
  • For 8 mm screw (maximum value), a torque of 30 nm is used.

torque, electrical, screwdriver, device

The correct selection of the speed of rotation will not only work with greater efficiency. It also provides high quality, reliability and long service life of a screwdriver. With a large torque, the tasks are performed faster, and the master does not make much effort.

For tools working from the network, the power of rotation does not have much influence on performance. But the battery models sit much faster. That is why for professional tools it is recommended to always have a spare battery or device for quick charging. When buying professional tools, spare batteries are usually included, but household models will have to purchase them on their own.

Important! When buying a tool, it is worth paying attention to the presence of the return mode, it will help free the nozzles during stuck. On electrical screwdrivers, reverses are electronic, to turn it on, two.Position switches are used near the launch key
