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 Torque calculation to a drive a roller Dimensions We've a roller of length 400mm & Dia of 90mm. At both ends of the roller a shaft is fitted. Shaft dia is 25 mm & length is 100mm each side. On the 25mm Dia shaft, two flanged bearings are fitted. The total roller & shaft weight is 6 kgs. Working Principle:

CONVEYOR POWER CALCULATOR. Use this calculator to calculate the force, torque and power required from a conveyor to move a load at an angle. If your conveyor is horizontal enter an angle of 0. Enter your values for the Mass, Diameter, Beltspeed, Friction and Angle; select your units as required. COEFFICIENT OF FRICTION.

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

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 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 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 ...

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

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

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. Sep 9, 2014 #9 saruvanan 10 0 Let me rephrase my question Dimensions

The bending torque M K acting on the roller can be determined according to the principle of equal function. The bending work AK produced by bending torque on the roller shall be equal to the work AP for plastic deformation of steel plate, i.e. A p = A k (shown in Fig. 3). Fig. 3 Variation of bending moment along plate length

To determine the root mean square (continuous) torque, we first calculate the torque values required during each phase of the move profile. Torque required for constant velocity For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a ) on the belt multiplied by the radius (r 1 ) of 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.
