Mar 12, 2019· The ' torque-band ' in an engine curve represents its pulling ability which determines a vehicle's ' driveability ' & ' acceleration '. Torque is most needed while moving a vehicle from the stand-still and/or climbing a slope. Similarly, heavier is the vehicle or a vehicle with full rated load requires a higher amount of torque to pull it and ...
These calculations are based upon theoretical values and are only intended for planning purposes. Actual results will vary. No responsibility from Kennametal is assumed.
Torque and Power in Cold Rolling *Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.*The total rolling load is distributed over the arc of contact. *However, the total rolling load can be assumed to be concentrated at a point along the arc of
Roll force and torque are derived by means of two independent integrals. Thus, the lever arm coef-ficient is evaluated from the expressions for roll force and torque using conventional rolling theory. Roll-ing trials report good agreement with theory. Measured roll forces are similar to calculated forces.
mill. The first system (with specific sensors) is an online vibration monitoring system for control on-line the sheet quality and mill maintenance in relation with diagnostic functions. The second system is used to monitor the torque and to measure the mill parameters as well (the force, the mill speed, the gap between work roll etc.).

Jul 01, 2009· I was thinking the same thing about the hammer mill with no load. We are spinning a really heavy roll (100k lbs.) with hammers that will swing out under centrifugal force and with no resistance except for windage and bearings. I have amp readings for the same mill running with no load for two different motors at 450 and 600rpm.

Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. ... Calculate the value for load torque, load inertia, speed, etc. at the motor drive shaft of the mechanism. Refer to page 3 for calculating the speed, load torque and load inertia for various
As the speed changes, the load torque remains constant and the horsepower changes linearly with speed. Constant torque loads cause motors to draw relatively high current at low speeds when compared to variable torque applications. This is why the same size drive may have a lower HP rating for Constant Torque applications.
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.
DuoDrive Talk about torque. Pinch roll reducers use one worm on the power input shaft to turn two gears simultaneously, in opposite rotations. Pinch roll reducers are designed for applications such as cold-roll forming, tube mills and wire mills, where very high torque is needed to smoothly propel metal through high pressure mill rollers.
The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece.
