How much torque do I need?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

How much torque do I need in a driver?

Generally speaking, an impact driver with 1500–1800 in-lbs of torque puts more emphasis on higher RPM. It will do 95% of the work more quickly than a tool with more torque and slower speeds. Our rule of thumb is that, if you need to reach for a socket adapter, you're better off grabbing an impact wrench.

How do I choose a motor torque?

The load torque should be between 75%-100% of the rated motor toque with 95% being an ideal choice. For constant speed applications where the motor will run continuously at rated speed you do not need to work out torque. You can simply look at load power and motor power and use the same 75%-100% rule.

How much torque do you need for automotive work?

Very heavy duty automotive fasteners require between 200 and 1,000 ft. lbs of torque, or even higher amounts. Applications include camshaft sprockets and harmonic balancers. Many off-road vehicles or performance racing vehicles will require torque applications in this range as well.

How do I know if I need torque a bolt?

DETERMINING TORQUE

The general equation for bolt load based on applied torque is T = KF_iD_b where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.

HORSEPOWER VS TORQUE SIMPLEST EXPLANATION

How do you calculate torque specs?

Where To Find The Correct Manufacturer Recommended Torque Specs. The torque specs for the axle nut (and other nuts and bolts) should be listed in the dealership/shop guide provided by the manufacturer. If you can't find that information, or if you don't have a guide, you can find the specs in the service manual.

Is more torque better in a drill?

The key to drill performance is being able to deliver the required torque at the highest speed. A common misconception is: the higher the torque rating, the faster the drill will complete an application.

How many ft lbs impact wrench do I need?

An impact wrench needs about 500 ft-lbs of torque to remove lug nuts. In most cases, you will need the same amount of torque you used to tighten the lug nut in order to remove it. So, if you over-tightened it, you might need more than 500 ft-lbs torque.

Do Impact drivers have torque control?

Impact drivers do not have torque control, so the only way to adjust the amount of torque being delivered is by using the speed control trigger (or by selecting a model with several gears). These tools are extremely powerful, producing up to 150Nm of torque!

How big of a motor do I need?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.

How do I choose an engine horsepower?

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.

How do you choose an engine for a load?

The most critical consideration for selecting a motor in these cases is to choose one whose speed-torque curve exceeds the load torque curve. Loads from centrifugal pumps, fans, blowers, compressors with unloaders, and similar equipment tend to be variable over time.

How does torque affect ball flight?

If we think about torque affecting how the club head is delivered to the ball at impact, you can imagine that it would affect ball flight. One study in 2017, showed that shafts with a higher torque caused a more open club face at impact which led to a slightly higher launch that tended to go right.

What's torque in a golf shaft?

Torque is defined as “a twisting force that tends to cause rotation.” In the case of a golf shaft, it's the amount of twisting (or lack thereof) that occurs during the swing.

What does low torque mean in a golf shaft?

A low torque shaft means that the shaft actually has a high degree of resistance to twisting. The “low” refers to the number assigned to the torque value. For example, a shaft that has a torque value of 2.5* has a very low degree of torque, which means that is has a high ability to resist twisting.

How strong of an impact wrench do I need to remove lug nuts?

Lug nuts might have been over-tightened during previous servicing. If you tighten a lug nut to 100 ft-lbs, you should be able to immediately remove it using a tool that can deliver 100 ft-lbs of torque.

What size impact do I need to remove lug nuts?

The most common size for the average DIYer or automotive enthusiast is the ½-inch impact wrench, which has enough power to turn the lug nuts of a typical car.

Can a 3/8 impact wrench remove lug nuts?

A 3/8-inch impact wrench may be your best option if you want a small, lightweight tool that can yet fit in tight spaces while still delivering a fair amount of torque. However, you should be aware that attempting to remove rusty and stubborn nuts and bolts may turn impossible while using this tool.

How much drill torque do I need?

The more settings the finer your control while working. Newton Metres (Nm) on drills: 4 to 15Nm is fine for all of those smaller screw driver tasks around the home. 15 to 35Nm is a great all-rounder to drill and drive medium sizes screws and hole drilling.

How do you choose a drill torque?

How much torque does a cordless drill have?

How much torque does an average cordless drill have? As mentioned earlier, the torque of an average cordless drill goes up to 10 or 20. Whatever drill you own, the number sequence is quite similar and typical. They all work in the same manner, no matter the maximum torque level.

Are torque specs important?

When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation. Following exact torque specifications matters for a number of reasons. Too much torque can result in overtightening, which has significant consequences.

Do mechanics use torque specs?

We absolutely use torque specs, especially when we're working with unfamiliar equipment. I always carry a torque wrench in my toolbox. Using them is great, easy insurance for a mechanic.

Which motor is the best?
