Advantages of roller screw:

1.在同樣體積的情況下，滾柱絲杠有更大的接觸面積，將承載力平均分散在更大的表面。從而減小了摩擦力并延長了使用壽命。

1. In the case of the same volume, the roller lead screw has a larger contact area, and the bearing capacity is evenly distributed on a larger surface. Thus, the friction force is reduced and the service life is prolonged.

2.滾珠絲杠的珠子在輥道相互運動的方向不同，而滾柱是同步運行在主絲杠上的。于此滾柱絲杠能承受更高的輸入轉速從而實現更大的直線速度。

2. The beads of the ball screw move in different directions with each other on the roller table, while the roller runs on the main screw synchronously. In this way, the roller lead screw can bear higher input speed to achieve greater linear speed.

3.滾珠絲杠內的珠子在輥道內需要在某一點上做方向切換，滾柱與主絲杠與同步做圓周運動，這就是為什么滾柱絲杠擁有更小振動和噪音。

3. The beads in the ball screw need to switch directions at a certain point in the roller table, and the roller and the main lead screw move in a circle synchronously, which is why the roller lead screw has less vibration and noise.

傳動轉速達5000r/min，高線速度達2000mm/s，荷載運動可達1000萬次以上，與現代的滾珠絲杠相比，其軸向承載力高3~5倍以上，使用壽命高10倍以上

The transmission speed reaches 5000r/min, the high linear speed reaches 2000mm/s, and the load movement can reach more than 10 million times. Compared with the modern international advanced ball screw, its axial bearing capacity is more than 3-5 times higher, and its service life is more than 10 times longer

滾柱絲桿分類

Classification of roller screws

行星滾柱絲杠分類為：滾柱非循環式與滾柱循環式。

Planetary roller lead screws are classified into roller non circulation type and roller circulation type.
