The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl + M seal.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

I want to calculate the required force to bend a 10 mm thick plate which is 2,500 mm wide. The rolling machine is connected to a 10 HP motor with a gear box and the rollers have an rpm of 8.Answer (1 of 3): Power(kW) = Torque(Nm) × Speed(rpm) / 9550 You will get Torque from this equation, Torque(Nm) = Weight(kg) × 9.81 (N/m2) × D(Dia. Of shaft)/2 From above equation, you can get minimum required dia. of shaft.

Now you can calculate the torque for this load at this speed assuming that you know efficiency of the motor. Our estimated 15% efficiency represents maximum efficiency of the motor which occurs only at a certain speed. Efficiency may be anywhere between zero and the maximum; in our example below 1000 rpm may not be the optimal speed so the for ...The Wheel Torque calculated in Step Five is the total wheel torque.

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.

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 ...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.

Answer: In the absence of mass of the shaft and with no friction, no torque is needed to rotate the shaft. If the mass of the shaft is negligible, then the important thing is the load.
