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.

03-11-2008· 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.

Diameter based torque, from an external source or by calculation provides the torque reference required to maintain constant tension as the roll package builds to maximum diameter. When calculating diameter using winder motor speed, a memory circuit can hold the diameter information until reset so that stopping and restarting a partially built roll is possible with limited tension disturbances.

Then, when we calculate the Acceleration Torque in Torque Calculation we divide the total the total inertia by the gravity from. Gravity = 386 in/sec². oz-in² = Inertia based on weight; oz-in-sec² = inertia based on mass; Calculation for oz-in² to oz-in-sec². Torque. Torque is the tendency of a force to rotate an object about an axis.

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 rotate the system at specified rotational speed and acceleration.

Companies that manufacture conveyor systems probably have software tools that calculate the motor size for them. But for someone who doesn't have this software, how does one go about determining what size motor they need to drive a 6000lbs load over a conveyor of length 20 feet.

The minimum torque needed to completely stop the motor shaft from ... If the wheels roll without slipping no power is dissipated by friction between the ... This is the no load case. Assuming no internal friction the wheel will turn at Wn. The speed of the vehicle will be rWn. Case 2: Free rolling with no external forces and a lot of weight ...

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. T=IxA "I" inertia for a solid shaft, I=1/2MR^2 = 1/2*0.925lb * (1.095in)^2 = 0.55 lb-in^2 "R" - radius = (2.19in/2)= 1.095in "M ...

Calculate the radius accurately, otherwise it will easily cause a large deviation. 4, compared with common calculation methods. Calculate the above example according to the usual calculation method: = 0.20m, =0.87m, N=30 conveyor belt length is: L=1/2(2z X 0.20+2.n×0.87)X 30=100.79m

Derivation of the exact formula. To calculate the exact length of the spiral, we write the equation of the curve in polar coordinates: Here ρ is the distance between the axis as a function of the angle φ.φ is expressed in radians and is 0 at the beginning and increases by 2π every turn. So, every turn the radius ρ increases by h.. To calculate φ we proceed as we did before to calculate N ...

Torque What is Torque? Torque (pronounced “tork”) is a force that you use to rotate or turn things. You generate torque any time you apply a force using a wrench. Tightening the lug nuts on the wheels of your car is a good example of torque. When you use a wrench, you apply a turning force to the handle. This torque turns the lug nut.

However, that is the absolute minimum torque just to keep the system in steady state. It leaves nothing for actually accellerating the mass and for overcoming the inevitable friction. To get the real torque required, you have to specify how fast you want to be able to accellerate this mass upwards. For example, let's say you need at least 3 m/s².

24-04-2017· Most engines use horsepower to describe how much work they can do in a given amount of time. The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second. Because horsepower, like wattage (no coincidence ...

27-05-2008· The motor has a 5/8in gear of 17teeth and each roll has the same gear as the motor at one end. I have a steady velocity, so a=0. Thus torque=friction=FcxMxg. Am i correct? And if so do i have to divide the torque calculated with the number of rolls? Because the torque that i calculate is much higher than the motor torgue.
