Flower blue bolt in coal mine of usage
In general machine tools it has thread, that screw.
1, according to GB/T17587.3-1998 and applications, ball screw can be used to the rotary motion into linear motion; Or the linear motion into rotary motion of the actuator, and has high transmission efficiency, accurate positioning and characteristics;
2, when screw as active body, nut can follow screw rotation Angle, in accordance with the corresponding specification lead into linear motion, passive workpiece can through the nut seat and nut connection, so as to realize the corresponding linear motion.
3, ball screw wire between mother because there is no gap, linear motion accuracy is higher, especially in frequent commutation without backlash compensation. Ball screw wire mother friction between the small, turns very easily.
4, ball screw and motor connection must be among the coupling to achieve soft connection. Synchronous belt, can directly use synchronous wheel and motor output shaft connection.
5, ball screw pair, on the basis of the national standard GB/T17587.3-1998, divided into positioning the ball screw pair (P) and drive the ball screw pair (T) two kinds big. Accuracy grade is divided into seven levels, namely 1.2.3.4.5.7.10 level, grade 1. In turn reduce the highest accuracy.
6, ball screw rotation week nut moving distance for a pitch distance, if it is screw every turn a week nut mobile four spiral distance, then said the screw is four wire screw, commonly known as the four head screw. General small lead ball screw is single, medium, or large lead to use two line or line.
