Screw torque formula
Webb4 mars 2006 · Torque=total torque for both screw shafts, denoted in Newton-meters (N-m), kW=motor rating on the HSEI twin-screw extruder. For example: If a HSEI twin-screw extruder with a 60-mm screw diameter has a torque rating of 2800 N-m and uses a 200-kW motor if geared for 600 rpm, then a 400-kW motor would be specified at 1200 rpm as … WebbT R = F d m 2 ( l + π μ d m π d m − μ l) + ( F μ c d c 2) Neither of the mean diameters for the square thread, nor the collar were given. However, I found that the mean diameter of the square thread can be determined from the pitch, l, and nominal diameter, d n, by d m = d n − l 2
