Linear guide rail pairs usually exist in pairs, and non reference guide rails should also be spliced and installed according to the same steps and methods.

直线模组的性能指标可以从以下方面进行衡量。

The performance index of linear module can be measured from the following aspects.

直线模组的精度特性：包含重复定位精度、定位精度、行走平行度、行走直线度、

Accuracy characteristics of linear module: including repeated positioning accuracy, positioning accuracy, walking parallelism, walking straightness

背隙等。

Back space, etc.

直线模组的运动特性：可搬运重量、抗力矩能力、运行速度、加速度、运行噪音等。

Motion characteristics of linear module: transportable weight, torque resistance, running speed, acceleration, running noise, etc.

直线模组的选型可参照下面的步骤：

Refer to the following steps for model selection of linear module:

1.确定模组滑台的使用环境：根据使用环境判定为一般环境，洁净环境，恶劣环境?

1. determine the operating environment of the module slide: determine whether it is a general environment, a clean environment or a harsh environment according to the operating environment?

2.确定模组滑台安装方向。确定模组滑台为水平安装，墙面安装或垂直安装。

2. determine the installation direction of module slide. Confirm that the module slide is installed horizontally, wall mounted or vertically.

3.确定模组滑台搬运的负载。

3. determine the load carried by the module slide.

4.核算模组滑台运行的速度和加速度。

4. check the speed and acceleration of the module slide.

5.模组滑台的容许力矩校核：计算静止（匀速）状态下和加减速状态下的各向力矩值：Ma，Mb，Mc。

5. allowable torque check of module slide: calculate the torque values in all directions under static (constant speed) state and acceleration and deceleration state: Ma, MB, MC.

6.模组滑台的精度等级要求：明确需要的重复定位精度，行走平行度要求等。

6. accuracy grade requirements of module slide: specify the required repeated positioning accuracy, walking parallelism requirements, etc.

7.确定马达安装样式：常用的模组滑台安装方式有直连型，马达左侧安装，马达右侧安装，马达底侧安装等。

7. determine the motor installation style: the commonly used module slide installation methods include direct connection type, motor left side installation, motor right side installation, motor bottom side installation, etc.

8.模组滑台行程限位开关方式。

8. module sliding table travel limit switch mode.

9.确定模组滑台的电机规格和功率。

9. determine the motor specification and power of the module slide.
