Jan 01, 2017Fig. 2 shows a test drive used to measure the position deviation in control motion. The ball screw, rotated by a servomotor, drove the table supported by a friction-less aerostatic guideway. The ball screw was mounted on the test drive, while keeping the runout of the shaft end within 3 μm and the parallelism between the screw shaft and the guideway within 10 μm.

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in

Characteristics of ball screws • High mechanical efficiency In ball screws, about 90% or more of the force used to rotate the screw shaft can be converted to the force to move the ball nut. Since friction loss is extremely low, the amount of force used to rotate the screw shaft is as low as one third of that needed for the acme thread lead screw.
