What is a screw screw drive?

Ball screw drive is a device that adds a linear movement with high load used to activate another device using accurately machined lead screw and ball bearings. The output movement of the drives is achieved by placing several rows of Helically arranged, captured ball bearings in the sleeve, which acts as an agent of movement. The rows of the balls are arranged to match the pitch of the lead threads of lead screws as they pass the nut. Thus, the coach lies in the lead screw fibers and, as it turns, causes the matrix to move up or along its length. The matrix is ​​connected to the control arm, which is used to transmit the movement of mats to the activated device.

drives are remote devices used to produce work by transforming energy sources, usually electric current or compressed gas and oil, into linear or rotary movement. The output movement then used them to switch, move or activate a secondary device where the non -tranalized PRAbout the operator to do it. The ball screw drive is one such device that creates a linear or straight output movement from the rotary input. The input energy is usually supplied by an electric motor and is translated into linear power using a precisely machined lead screw and a set of captured ball bearings.

ball bearings used in the ball screw drive are located in precisely processed grooves in a metal or composite sleeve. The lead screw passes through the sleeve with one end -supported shrub or bearing and the other connected to the engine drivers. The sleeve coach is arranged to match the precise pitch and spacing of the lead screws and are located in such a way that they lie comfortably in these fibers. When the engine turns the lead bolt, the balls function as the threads of the rotating nut, allowing the sleeve to move up and down along the length of the bolt with minimal friction. The sleeve is connected to the output arm of the device that transmits its movement to the mechanism requiring activation.

The

precise movement of the low -friction ball screw mechanism allows the device to produce very high levels or torque activation with a very low load on its working parts. The inherent accuracy of the mechanism also causes a very high level of accuracy at the output of the driver. Thanks to these characteristics, the ball screw driver is the ideal choice for precise applications with high load.
