We will need to know the number of inches pre revolution. This is pretty easy since it's the screw # of threads per inch. You will also need to know the pi. Pi is half of a circle in radians, or 3.1415927 rounded to the ten millionth. The formula is as follows: Torque = ( (weight) (inches/revolution))/2 (pi) (efficiency).
Tc = torque required during constant velocity (Nm) Fa = total axial force (N) r1 = radius of drive pulley (mm) η = efficiency of belt drive system. Notice that the efficiency (η) of the belt drive system is included in the torque equation. This efficiency accounts for losses such as friction between the belt and pulleys.

P: Pitch of the lead screw (in ...
The torque is obtained by integrating the frictional force multiplied by roll radius over the arc of contact (lagging and leading zones). The negative sign before the second term is due to the fact that in leading zone the metal moves faster than the rolls hence it helps to rotate the rolls. The above integration leads to rather complex ...
