直线导轨和滚珠丝杆区别很大，虽然同属直线传动设备，但是其工作原理要求以及使用范围都不一样，但两者的表现在直线传动方面表现却都非常出色。

There is a significant difference between linear guides and ball screws. Although they both belong to linear transmission equipment, their working principle requirements and scope of use are different. However, both have excellent performance in linear transmission.

滚珠丝杠是工具机械和精密机械上zui常使用的传动元件，是由螺杆螺母钢球预压片反向器防尘器组成。其主要功能是将旋转运动转换成线性运动，或将扭矩转换成轴向反复作用力，同时兼具高精度可逆性和率的特点。主要用于一些机床大型设备雕刻机械等较为普遍，非常方便的把旋转的运动转换成直线运动，用起来非常方便，从而减少整个设备在旋转方面的磨损大大降低。

Ball screw is a commonly used transmission component in tool machinery and precision machinery, consisting of screw, nut, steel ball, pre press plate, reverser, dust collector. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing high precision reversibility and high efficiency. It is mainly used for some large machine tools, equipment, carving machinery, etc. It is very convenient to convert rotary motion into linear motion, which is very convenient to use and greatly reduces the wear and tear of the entire equipment in terms of rotation.

直线导轨使用非常广泛但种类很多，方型四排高珠导轨用于一些大型机床设备，如平面磨床，切片机线切割等；也因工作条件的不同选用的直线导轨也是不同的，zui适于精密测量仪器半导体制造和检验设备非标自动化机械设备以及其他精密直线运动为重要的应用场合等，因不同设备需要选择正确的导轨也是关重要的。

Linear guide rails are widely used but have many types. Square four row high ball guide rails are used in some large machine tools and equipment, such as surface grinders, slicers, and wire cutting; The selection of linear guides varies depending on the working conditions. They are suitable for precision measurement instruments, semiconductor manufacturing and inspection equipment, non-standard automated mechanical equipment, and other applications where precision linear motion is crucial. Choosing the correct guide is also crucial for different equipment needs.

与滑动丝杆副相比驱动力矩为

Compared to the sliding screw pair, the driving torque is

由于滚珠丝杆副的丝杆轴与丝母之间有很多滚珠在做滚动运动,所以能得到较高的运动效率.与过去的滑动丝杆副相比驱动力矩达到1/3以下,即达到同样运动结果所需的动力为使用滚动丝杆副的1/3.在省电方面很有帮助。

Due to the rolling motion of many balls between the screw shaft and the screw nut of the ball screw pair, high motion efficiency can be achieved. Compared with previous sliding screw pairs, the driving torque can reach less than 1/3, which requires 1/3 of the power required to achieve the same motion result when using a rolling screw pair. This is very helpful in terms of power saving.

高精度的保证

High precision assurance

滚珠丝杆副是用日本制造的世界zui高水平的机械设备连贯生产出来的,特别是在研削组装检查各工序的工厂环境方面,对温度·湿度进行了严格的控制,由于完善的品质管理体制使精度得以充分保证

The ball screw pair is produced continuously using world-class mechanical equipment manufactured in Japan, especially in the factory environment for grinding, assembly, and inspection of various processes. The temperature and humidity are strictly controlled, and the precision is fully guaranteed due to a sound quality management system

微进给可能

Micro feed may

滚珠丝杆副由于是利用滚珠运动,所以启动力矩ji小,不会出现滑动运动那样的爬行现象,能保证实现精确的微进给

The ball screw pair utilizes ball motion, so the starting torque is small and there will be no crawling like sliding motion, ensuring accurate micro feed

无侧隙刚性高

No side gap, high rigidity

滚珠丝杆副可以加予压,由于予压力可使轴向间隙达到负值,进而得到较高的刚性(滚珠丝杆内通过给滚珠加予压力,在实际用于机械装置等时,由于滚珠的斥力可使丝母部的刚性增强

The ball screw pair can be subjected to preloading, which can cause the axial clearance to reach a negative value, thereby obtaining higher rigidity (in the ball screw, preloading is applied to the ball, and when used in mechanical devices, the repulsive force of the ball can enhance the rigidity of the screw head)

高速进给可能

High speed feed may

滚珠丝杆由于运动效率高发热小所以可实现高速进给(运动)。

Ball screw can achieve high-speed feed (motion) due to its high motion efficiency and low heat generation.
