Ball screw as a very common CNC lathe and many precision instrument parts, each component has a very important role, related to the quality of products. Today, let's talk about the function of ball screw reverser.

滾珠絲杠反向器有多種形式，滾珠絲杠反向器的主要作用就是連接滾珠循環的兩端，使每個滾珠循環回路都是一個閉路循環，滾珠絲杠反向器會在螺帽和滾珠絲杠軸之間做無限循環運動。

There are many forms of ball screw reverser. The main function of the ball screw reverser is to connect the two ends of the ball cycle, so that each ball cycle circuit is a closed cycle. The ball screw reverser will make an infinite cycle movement between the nut and the ball screw axis.

滾珠絲杠滾珠的不同的循環方式反相器也不一樣，滾珠絲杠滾珠內循環的一般是鏈接相鄰兩條滾道形成一個循環回路。

The different circulation ways of the ball screw and the inverter are also different. The internal circulation of the ball screw and the ball is to link two adjacent raceways to form a circulation loop.

端蓋循環滾珠絲杠和端部導流滾珠絲杠是在螺母兩端各有一個反向器，形成循環回路。

The end cap circulating ball screw and the end guide ball screw have a reverser at each end of the nut to form a circulating circuit.

如果是外循環滾珠絲杠，那么通常就是使用一根彎管將鋼球從一頭導出再從另一頭導入形成循環回路。

If it is an external circulation ball screw, it usually uses a elbow to lead the steel ball out from one end and then lead it in from the other end to form a circulation circuit.

內循環有三種反相器，按照外型分為，圓形和腰型，還有這一種是反向板，配合螺母內螺紋弧度安裝進去，用S型彎道進行循環，國內非常長見的是圓形內循環反相器，而且是塑膠的，國外一般采用金屬腰型反向器居多。

There are three types of internal circulation inverters, which can be divided into round and waist type according to the appearance. The other type is reverse plate, which is installed with the internal thread radian of nut, and circulates with S-shaped curve. Circular internal circulation inverter is very common in China, and it is plastic. Metal waist type inverter is generally used in foreign countries.
