Answer: Trapezoidal screw belongs to a type of spiral transmission. By transmitting motion and power through the rotation of nuts and screws, rotational motion can be transformed into linear motion. The trapezoidal screw has the characteristics of high transmission efficiency, accurate positioning, and high load-bearing capacity
Answer: The motion principle of trapezoidal screw and ball screw is the same, the difference is that there are no balls in trapezoidal screw, so the motion between the nut and the screw shaft is completely generated by mechanical contact to produce sliding. So the main difference between the two structures can be summarized in one sentence: ball screws are rolling friction, while trapezoidal screws are sliding friction
Answer: The trapezoidal screw is composed of a screw and a nut, with a relatively simple structure that is easy to install and maintain; Has good self-locking performance and can maintain position stability without applying external force; The manufacturing process of trapezoidal lead screw is relatively simple and can be processed by turning, grinding and other methods, with lower processing costs; Trapezoidal screw is suitable for various transmission systems, including machine tools, automation equipment, industrial machinery, etc. Due to its simple structure and high strength, trapezoidal screw has high reliability and durability; Under normal usage conditions, the trapezoidal screw can operate stably for a long time, reducing the frequency of malfunctions and repairs
Answer: Trapezoidal screw has a relatively simple structure, easy installation and maintenance, good self-locking performance, low processing cost, and high strength. When these requirements are met, trapezoidal screw can be used
