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. Conversely, the torque driving the
If posible i need calculation steps P=Tω power = torque . angular velocity To calc power required (for a constant speed) you need to figure out/measure the opposing torque due to whatever loads are acting and know what speed the roller needs to run at.

It also requires the gear train mechanism with the motor to drive roller, to transfer torque to overcome the vertical load acting during operation, and speed reduction for ease bending & rolling process. Thus analysis of load acting on the gear tooth is necessary to set the minimum inside radius of roll for 3-roller bending machine.

Torque and Newton's Second Law for Rotation Torque, also known as the moment of force, is the rotational analog of force. This word originates from the Latin word torquere meaning "to twist". In the same way that a force is necessary to change a particle or object's state of motion, a torque is necessary to change

Pay enough attention when calculating the load torque. * The transmission efficiency η between the motor and load varies depending on the ...
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.
The presentation covers the different aspects of machines including unwinds, rewinds and point-to-point applications. It also looks at the different methods of control be it either speed or torque. Lastly we will explore the different types of tension systems including: manual, open loop and closed loop. We will discuss different components

to is massless.) To illustrate, we will calculate the moment of inertia for a mass of 2 kg at the end of a massless rod that is 2 m in length: I= mr2 = (2 kg)(2 m)2 = 8 kg m2 If a force of 5 N were applied to the mass perpendicular to the rod (to make the lever arm equal to r) the torque is given by: ˝= rF= (2 m)(5 N) = 10 N m

The Wheel Torque calculated in Step Five is the total wheel torque. This quantity does not change with the number of drive wheels. The sum of the individual drive motor torques (see .

rot= rotational mechanical power M = torque ω = angular velocity The most commonly used unit for angular velocity is rev/min (RPM). In calculating rotational power, it is necessary to convert the velocity to units of rad/sec. This is accomplished by simply multiplying the velocity in RPM by the constant (2 x π) /60: = × 60 2 /sec

High-speed, high-torque machines are often—but not always—one or two barrel sections longer than a conventional twin-screw. The highest screw speeds apply only to smaller screw diameters. W&P's ZSK MegaCompounders go up to 1200 rpm but only in sizes up to 70-mm diam. At 133-mm, maximum speed is 1000 rpm.
1 August 15, 2007 1 17. Shaft Design Objectives • Compute forces acting on shafts from gears, pulleys, and sprockets. • Find bending moments from gears, pulleys, or sprockets that are transmitting loads to or from other devices. • Determine torque in shafts from gears, pulleys, sprockets, clutches, and couplings. • Compare combined stresses to suitable allowable stresses,
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. Typically, a safety factor is used so that the ...
P r = synchronizing torque coefficient W = weight of all rotating parts in pounds k = radius of gyration of rotating parts in feet. When a pulsating torque is applied to its shaft, the synchronous machine rotor will oscillate about its average angular position in the rotating magnetic field produced by the currents in the stator.
It is difficult to find the torque required because you need to know friction, which is difficult to estimate. A company I know who makes conveyors for large animal cages assumes a friction coefficient of 1.0, in other words if you hang the load off the side the conveyor and tilt the machine up, it would be strong enough to lift it vertically.
The roller rotates and the output gear of the reducer meshes with the gear of the lower roller to provide torque for rolling the plate. The disadvantage of this machine is that the end of the sheet needs to be pre-bent by means of other equipment. W11 Series Mechanical Three-Roller Asymmetrical Plate Bending Machine
