絲杠是將旋轉(zhuǎn)運(yùn)動變成直線運(yùn)動的傳動副零件，在機(jī)床上，它是用來完成進(jìn)給運(yùn)動的一個重要原件。機(jī)床絲杠不僅要能準(zhǔn)確地傳遞運(yùn)動，而且還要能傳遞一定的動力。所以它在精度、強(qiáng)度以及耐磨性各方面，都有一定的要求。絲杠是一種精度很高的零件，絲杠的加工從毛坯到成品的每道工序都要周密考慮，以提高其加工精度

A screw is a transmission component that converts rotational motion into linear motion. In machine tools, it is an important component used to complete feed motion. Machine tool screws not only need to be able to accurately transmit motion, but also need to be able to transmit a certain amount of power. So it has certain requirements in terms of accuracy, strength, and wear resistance. A lead screw is a high-precision component, and every step of the machining process from the blank to the finished product needs to be carefully considered to improve its machining accuracy

　　1、絲杠的分類

1. Classification of lead screws

　　機(jī)床絲杠按其摩擦特性可分為三類:滑動絲杠、滾動絲杠及靜壓絲杠。

Machine tool screws can be divided into three categories based on their friction characteristics: sliding screws, rolling screws, and static pressure screws.

　　滑動絲杠的牙型多為梯形。這種牙型比三角形牙型具有效果高，傳動性能好，精度高，加工方便等優(yōu)點(diǎn)

The tooth shape of the sliding screw is mostly trapezoidal. This tooth shape has advantages such as higher effectiveness, better transmission performance, high accuracy, and convenient processing compared to triangular tooth shapes

　　滾動絲杠義分為滾珠絲杠和滾柱絲杠兩大類。滾珠絲杠與滾柱絲杠相比，摩擦力小，傳動效率高，精度也高，因而比較常用，但是其制造工藝比較復(fù)雜。

Rolling screw is divided into two categories: ball screw and roller screw. Compared with roller screws, ball screws have lower friction, higher transmission efficiency, and higher accuracy, making them more commonly used. However, their manufacturing process is more complex.

　　靜壓絲杠有許多的優(yōu)點(diǎn)，常被用于精密機(jī)床和數(shù)控機(jī)床的進(jìn)給機(jī)構(gòu)中。其螺紋牙形與標(biāo)準(zhǔn)梯形螺紋牙形相同。但牙形高于同規(guī)格標(biāo)準(zhǔn)螺紋1.5～2倍，目的在于獲得良好油封及提高承載能力。但是調(diào)整比較麻煩，而且需要一套液壓系統(tǒng)，工藝復(fù)雜，成本較高

Static pressure screw has many advantages and is often used in the feed mechanism of precision machine tools and CNC machine tools. Its thread profile is the same as the standard trapezoidal thread profile. But the tooth shape is 1.5-2 times higher than the standard thread of the same specification, in order to obtain good oil seals and improve bearing capacity. But the adjustment is quite complicated and requires a hydraulic system, with complex processes and high costs
