ball screw driven actuators: the fundamental principle behind the ball screw driven actuator is essentially an improvement over a lead screw driven ball screw driven actuators, the rotation of the ball screw drives the ball nut/mounted carriage due to the fact that the interface between the stud and ball screw is essentially a ball bearing system, where hardened steel balls in .
ball screws. ball screws are mechanical linear actuators that create linear motion without friction. they are usually chosen as they have faster rates of speed with continuous duty cycles and can carry higher loads than lead screws. though they are the more expensive option, they are reliable and easily integrated into a project.
(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.
