Product Description


Precision Screw Pair
As a typical screw transmission, screw pair has the characteristics of mutual conversion between rotational motion and linear motion. According to the circulation mode, it is divided into internal circulation screw pair and external circulation screw pair. Internal circulation screw pair refers to a screw pair in which the ball never leaves the surface of the screw during the circulation process, and has the characteristics of compact structure, less friction loss, high transmission efficiency, good rigidity, etc.; external circulation screw pair refers to a screw pair in which the ball leaves the surface of the screw when the circulation is reversed, and has the characteristics of simple structure, good processability, and reliable operation.
Ball screw transmission is to place a proper amount of balls as intermediate transmission bodies between the screw and the screw nut spiral groove, and use the return device to make the balls form a spiral motion chain that circulates repeatedly in the closed loop. The relative motion of the screw and the nut is transformed into rolling contact by the action of the ball chain.

HIGH TRANSMISSION EFFICIENCY
Traditional sliding screw transmission has large friction resistance and low transmission efficiency, generally less than 40%. However, the ball screw pair uses rolling friction instead of sliding friction, which greatly improves the transmission efficiency, generally greater than 80%, and as the lead angle increases, the transmission efficiency will also increase, theoretically up to 98%

REVERSE TRANSMISSION IS POSSIBLE
The ball screw pair not only has high forward transmission efficiency but also can transmit in the reverse direction with high efficiency. It can convert rotary motion into linear motion.
It can also convert linear motion into rotary motion.

GOOD SYNCHRONIZATION PERFORMANCE
Since the friction coefficient of the ball screw pair is small, the starting friction resistance is almost the same as the movement friction resistance. Therefore, there is no vibration at startup, and no creep occurs at low speed. This not only shortens the startup time but also eliminates the slip phenomenon in sliding friction. The sensitivity and accuracy of the transmission are greatly improved, and it has the characteristics of continuous and smooth movement.

HIGH TRANSMISSION ACCURACY
Transmission accuracy mainly refers to positioning accuracy and repeated positioning accuracy. The ball screw with hardened thread grinding has good lead accuracy. When preloaded, the gap can be completely eliminated. If the preload force is appropriate, the rigidity of the transmission system can be improved and high positioning accuracy can be obtained without increasing the driving torque or reducing the efficiency.

LONG SERVICE LIFE
The screw, nut, and ball of the ball screw pair are all hardened, and the wear caused by rolling friction is extremely small. Therefore, the ball screw pair can still maintain good accuracy after long-term use and has a long service life, which is difficult to match with the sliding friction pair.
