- calculate torque to turn a roll

To determine a fan or blowers horsepower use the following equation.

Theoretically, zero torque is required to start the barrel turning as long as it starts out in equilibrium. To keep it turning at a constant speed, the required torque varies periodically with a time-average of zero. This assumes that there is no friction in the barrel and that the dirt doesn't roll around inside.

across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the rewind shaft must increase at a linear ratio, relative to roll diameter, as a rewind ...

How to Convert Torque to Force. ... The equation is simple, but if you are trying to calculate torque experimentally, you will need some measuring devices to obtain the values necessary in the equation. At a minimum, you need to know the amount of force applied to the system and the distance from the shaft to the point where the force is ...

How can I calculate roll center of a car on a turn? Update Cancel. ad by The Great Courses Plus. Discover the hidden workings of your world and beyond. ... How can I calculate torque of a supra car? What should be the distance between roll center and center of gravity in a formula car?

How do I calculate the minimum torque to rotate a .925lb, 0.625' diameter shaft with a .925lb 2.19' hub 10K rpm within 3 seconds? I am trying to spec out an electric motor that I can couple up to the shaft supported by two ball bearings to spin test the hub on.

In a car, torque is the force that pistons put on the crankshaft, causing it and the wheels to turn. While often considered an automotive term, torque is actually a general physics term that has ...

Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant.

Motor Torque Calculation Tel: (86)755-26434369 1 Web site: Motor Torque Calculation Selecting the proper motor and driver to meet a specific application needs motor torque calculation. Generally speaking, the user can follow the below …

Nov 03, 2008· Hello, I would like to know how to calculate the torque required to turn a roll which is supported symmetrically at both ends by bearings. A load is placed in the center of the roll due to the tension developed in the belt by the take up system on the other side of the conveyor.

From this, we can calculate the torque exerted by the mass (a torque which our gearmotor must be able to exceed in order to lift the mass). Alternatively, if we have already selected our gearmotor, it becomes a case of re-arranging the torque equation to find out either the maximum load, the motor can lift or the radius for the pulley.

wound until the diameter is 4 feet. If a 100 ft-lb constant torque is supplied to the center of the roll, the empty roll tension is 100 lbs. tension = torque/radius, radius = diameter/2, resulting in tension = 100 ft-lb/1 ft The tension at the roll surface will lessen as the diameter builds at constant torque.

Hi, Rolling Friction. The torque required [Nm] at the wheels is Maximum force[N] x radius of the wheel{m] T(wheel) = F x r. This has to be converted to the torque required at the machine side, which is …

Calculate the Torque required to lift the Force with the lever arm . T = F x d = 49.05 N x 0.5 m = 24.525 N-m . We cannot perform the lift with this set-up, because the stall torque is smaller than . the torque required for the lift. We must either shorten the length of the lever arm,

Calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or …

In physics, how much torque you exert on an object depends on two things: the force you exert, F; and the lever arm. Also called the moment arm, the lever arm is the perpendicular distance from the pivot point to the point at which you exert your force and is related to the distance from the axis ...

Horsepower to Torque Calculator is an online tool used in electrical engineering to calculate how much torque will be generated according to the input power value either in horsepower or watts. Generally, horsepower is a unit for measuring the power of various electrical motors, piston engines, steam turbines etc.

Jul 06, 2016· Typically, the pilot is expected to counter this force through the control inputs. To counter the aircraft roll left, the pilot applies right aileron. It is important to understand that torque is a movement about the roll axis. Aileron controls roll. Prop torque is …

The required tractive torque of the motor shall be equal to the tractive torque at wheel, T w = F t.r w, (i.e. Tractive Torque = Tractive Force x mean wheel radius).

When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.

Drive Wheel Motor Torque Calculations . Step Four: Determine Total Tractive Effort . The Total Tractive Effort (TTE) is the sum of the forces calculated in steps 1, 2, and 3. (On higher speed vehicles friction in drive components may warrant the addition of 10%-15% to the total tractive effort to ensure acceptable vehicle performance.)

I would like to calculate torque to rotate 1200 kg of mass which is attached in 1.5" dia shaft. Shaft is supported by 2 bearings at its end. Neglect bearing frication.

ACCELERATION TORQUE CALCULATION: When a machine must be accelerated to a given speed in a certain amount of time, the drive system HP may have to supply additional torque during acceleration to compensate for the load inertia. The acceleration torque must be added to the normal torque requirements of the machine.

Sep 14, 2014· Over the roller, a fabric in a roll form is loaded. The fabric roll sits over this roller by means of gravity. The roller has to drive the fabric roll on its circumference & feed the fabric end to another machine. Problem: 1. What is the torque required to drive the roller at the shaft end. 2.

To calculate horsepower, it is necessary to understand how it is related to torque and RPM. Examine the definition of horsepower. In British units, it is 550 ft*lb / …

Acceleration Torque These formulas will calculate the amount of torque required to accelerate or decelerate a load in a given period of time, or the amount of time it will take to accelerate or decelerate a load at a given torque.

Im trying to design a wheel that is supposed to rotate a balanced system (wheel is pinned to the body of the system, and will not turn unless force is applied) ... the problem Im having is that the system is very heavy(70kg) but the torque calculation results in an extremely small torque required to ...
