A ball screw (or ballscrew) 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 … See more Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the … See more The ball screw was invented independently by H.M. Stevenson and D. Glenn who were issued in 1898 patents 601,451 and 610,044 respectively. Early precise screwshafts were produced by starting with a low-precision screwshaft, and then See more Back-drive Because of their very high mechanical efficiency, especially compared to traditional lead screws, ball screws can potentially be back-driven (i.e., a linear force applied directly to the nut can induce a rotation of the … See more The circulating balls travel inside the thread form of the screw and nut, and balls are recirculated through various types of return mechanisms. … See more To maintain their inherent accuracy and ensure long life, great care is needed to avoid contamination with dirt and abrasive particles. This may be achieved by using rubber or leather See more Low friction in ball screws yields high mechanical efficiency compared to alternatives. A typical ball screw may be 90 percent efficient, versus 20 to 25 percent efficiency of an Acme lead screw of equal size. Lack of sliding friction between the nut and … See more Ball screw shafts may be fabricated by rolling, yielding a less precise, but inexpensive and mechanically efficient product. Rolled ball … See more WebJan 28, 2024 · The motor spindle is directly coupled to a helical screw, via the drive shaft, which in turn rotates in a ball screw nut. As the spindle rotates the ball screw nut is driven forwards, or backwards, along the helical screw. A hollow piston rod is attached to the ball screw nut and this creates the linear motion out of, or into the linear ...
