The difference between the trapezoidal screw and ball screw

First. different properties

1. Ball Screw: it is the most commonly used transmission element in tool Machinery and precision machinery.

2. Trapezoidal Screw: trapezoidal screw products are easy to be adjusted in combination with specific applications, in order to achieve the desired performance, while reducing cost control to a minimum.

Second. Different characteristics

1. ball screw pair: with high precision, good reversibility, high efficiency.Ball screw is widely used in various industrial equipment and precision instruments because of its small friction resistance.

2. trapezoidal screw: in the process of whirlwind milling screw, thread and knurling is completed once, high efficiency, low cost, low processing accuracy.The structure design idea and scheme have better application value.

Third. different uses

1. ball screw pair: its main function is to convert the rotary motion into Linear Motion, or to convert the torque into axial repetitive force, and the rotary motion into linear motion.This is a further extension and development of exEM screws.The significance of this development is to change the Bearing from sliding motion to rolling motion.

2. trapezoidal screw: suitable for rough machining of large threads.
