導軌有哪些分類

What are the classifications of guide rails

　　1：直線導軌

1: Linear guide rail

　　優點：摩擦力小，小動力即可移動，裝卸方便快捷，長度不限，適合長距離的機床設備。

Advantages: Low friction, easy to move with low power, convenient and fast loading and unloading, unlimited length, suitable for long-distance machine tools and equipment.

　　缺點：長期使用導軌會出現微變形影響精度和順暢、表面易生銹影響精度，而精度要求高則加重成本。

Disadvantages: Long term use of the guide rail may cause slight deformation that affects accuracy and smoothness, and the surface is prone to rusting that affects accuracy. However, high precision requirements will increase costs.

　　2：絲桿導軌

2: Screw guide rail

　　優點：具有精度高，壽命長，工作平穩，可靠性高，簡單可靠的優點，適合機床傳動設備使用。

Advantages: It has the advantages of high precision, long service life, stable operation, high reliability, simplicity and reliability, and is suitable for use in machine tool transmission equipment.

　　缺點：在長距離重負載下,絲桿易導致彎曲，滾珠絲桿制造、安裝精度要求較高，因而成本也較高;同時不宜作遠距離傳動。

Disadvantages: Under long-distance heavy loads, the lead screw is prone to bending, and the manufacturing and installation accuracy requirements for ball screw are high, resulting in higher costs; It is not suitable for long-distance transmission.

　　3：交叉導軌

3: Cross guide rail

　　優點：交叉導軌是面接式運動，效果比前者好，可承受各個方向的載荷，高精度、高平穩，造型小等優點，適合在小型設備使用。

Advantages: The cross guide rail is a surface mounted motion, which has better effects than the former. It can withstand loads in all directions, has advantages such as high precision, high stability, and small shape, and is suitable for use in small equipment.

　　缺點：行程有限，不方便清潔，裝卸精度要求較高，對潤滑的要求較低，不適合大型設備。

Disadvantages: Limited travel, inconvenient cleaning, high loading and unloading accuracy requirements, low lubrication requirements, not suitable for large equipment.
