如何正确选择直线导轨

来源:http://www.jngongrun.com/ 日期:2022-05-11 发布人:

线导轨的作用是用来支撑和引导运动部件,按照给定的方向进行往复直线运动。为了将正确类型的直线导轨运用于正确的场合,设计工程师就有必要了解不同导轨的优点和能力,从而进行合理的选择。

The function of the wire guide is to support and guide the moving parts to move back and forth in a straight line in a given direction. In order to apply the right type of linear guide rail to the right situation, it is necessary for design engineers to understand the advantages and capabilities of different guide rails, so as to make a reasonable choice.
由直线轴承和直线轴配合使用,从外观上来看是圆柱形的,可装配与圆形孔中。同时,直线轴承还可配合滑块使用,实现平面安装。圆形导轨的安装和使用都较为方便,节省空间。
It is used together by linear bearing and linear shaft. From the appearance, it is cylindrical and can be assembled in a circular hole. At the same time, the linear bearing can also be used with the sliding block to realize plane installation. The circular guide rail is convenient to install and use and saves space.
由方形滑块和方形导轨配合使用,从外观来看是方形的。从摩擦、可承受载负荷考虑,方形导轨是导轨与滑块面接触式摩擦,摩擦力较大,负载均匀,需要经常上油润滑。
The square slide block and the square guide rail are used together, which is square in appearance. Considering the friction and bearing load, the square guide rail is the contact friction between the guide rail and the sliding block surface. The friction is large and the load is uniform, so it needs to be lubricated frequently.
对于圆形导轨和方形导轨的选择,主要是从载荷、准确度、刚度、光洁度等几个因素来考虑。方形导轨的典型应用是对载荷能力、刚度和准确度要求较高的机床行业。但满足以上条件之后,就很难满足其他要求,如安装要求高、前期成本高、维护成本高。而圆形导轨在这方面就体现其优势当安装到平面度欠光滑的表面上时,仍然能够平稳运行。圆形导轨通常比方形导轨能够更快速地安装和更平稳的运行。综上所述,如何选择要根据实际需求,选择合适的才是好方案。
For the selection of circular guide rail and square guide rail, the load, accuracy, stiffness, finish and other factors are mainly considered. The typical application of square guide rail is in the machine tool industry which requires high load capacity, stiffness and accuracy. However, after the above conditions are met, it is difficult to meet other requirements, such as high installation requirements, high initial cost and high maintenance cost. The circular guide rail has its advantages in this respect. When it is installed on a surface with less smooth flatness, it can still run smoothly. Circular guideways are usually faster to install and run more smoothly than square guideways. To sum up, how to choose the right solution should be based on the actual needs.
