丝杆和导轨的级别是怎么区分的?

来源:http://www.jngongrun.com/ 日期:2021-10-06 发布人:admin

丝杆和导轨精度等级的基本定义师比较模糊的,大体的意思是为了反映出滚动体及相关组件的在不同配合间隙的情况下,导致的直线导轨定位面与基准面,或者丝杠的重复定位精度上出现的不同差异。

The basic definition of the accuracy grade of screw and guide rail is vague, which generally means to reflect the different differences between the positioning surface of linear guide rail and datum plane, or the repeated positioning accuracy of lead screw under the condition of different matching clearance of rolling element and related components.
如果你能理解滚珠丝杠在伺服系统中以及直线导轨在起精密导向元件时的作用的话,这个“精度等级”的概念就不难理解,说白了,高精度的丝杆就可以用在高精度的设备,当然高精度的丝杆价格也不菲。
If you can understand the role of ball screw in servo system and linear guide rail in precision guiding elements, the concept of "precision level" is not difficult to understand. To put it bluntly, high-precision screw can be used in high-precision equipment. Of course, high-precision screw price is not cheap.
至于这些指标,厂家有专门的测试设备给出结果,反映在我们这些客户眼中呢,我们只需要关心产品样本中写的行业内通用的标识即可。这些标识有的不同厂家叫法还可能不同。比如有的叫“普通级”,有的叫“一般级”,这样不同的叫法只是相对于自己厂家的“精密级”而言的,为了对比不同厂家之间的产品,我们还是看那些术语吧。
As for these indicators, the manufacturer has special test equipment to give the results, which are reflected in the eyes of our customers. We only need to care about the general marks in the industry written in the product samples. Some of these marks may be called differently by different manufacturers. For example, some are called "ordinary level" and some are called "general level". Such different names are only relative to the "precision level" of their own manufacturers. In order to compare the products of different manufacturers, let's look at those terms.
比如滚珠丝杠,有个“e300”和“e2π”这是行业通用的参数,下面地址是个pdf页面,有说明,但是他用的是“v300”和“v2π”是一样的。
For example, the ball screw has "E300" and "E2 π", which are common parameters in the industry. The following address is a PDF page with instructions, but it uses "V300" and "V2 π", which are the same.
