18/05/2016 (In ball screw terminology, we commonly refer to lead, which is the linear distance the screw moves for every complete rotation, rather than pitch, which is the linear distance between screw threads.) The equation for drive torque: Td = (Fa * P)/(2000 * π * η) demonstrates that torque, T, is directly proportional to the lead of the screw, P. Danielle Collins says. September 28, 2018 at 12:33 ...
