直线导轨跟滚珠丝杆区别非常大,实际上同为直线传动系统设备,殊不知其工作基本原理、要求及其运用范畴也不类同,但二者的表当时直线传动系统层面表明却都十分好。直线导轨与滚珠丝杆的作用在哪里不同?导轨丝杠厂家为您分析:
The linear guide rail is very different from the ball screw. In fact, it is the same linear transmission system equipment. However, its basic principle, requirements and application scope are also different. However, both of them are very good at the level of linear transmission system. What is the difference between linear guide and ball screw? The guide rail lead screw manufacturer analyzes for you:
1、定位精度:精度方面直线导轨传动减少了滞后的问题,定位精度高、通过不同位置检测结果反馈控制都会较旋转电机+滚珠丝杆且容易得到实现。
1. Positioning accuracy: in terms of accuracy, the linear guide rail transmission reduces the lag problem, and the positioning accuracy is high, and the feedback control through different position detection results will be easier to achieve than the rotary motor+ball screw.
2、重复精度对比:传动简单,减少了插补滞后的问题,滚珠丝杆间隙易受影响,而直线导轨更容易实现。
2. Repetitive precision comparison: the transmission is simple, reducing the problem of interpolation lag, the ball screw clearance is easily affected, and the linear guide rail is easier to achieve.


3、速度比较:因为离心力的作用,一般伺服电机在高速时会受力,所以速度和输出功率都是有限的。相对来说,直线导轨不受限制,没有机械损耗,提高了传动速度。
3. Speed comparison: because of the centrifugal force, the general servo motor will be forced at high speed, so the speed and output power are limited. Relatively speaking, the linear guide rail is unrestricted and has no mechanical loss, which improves the transmission speed.
4、行程对比:从行程来看,直线导轨的行程取决于定子和动子,理论来说就是直线导轨可以进行无限延长;而伺服导轨+丝杆由于承受负载、丝杆外径、精度不同等级等因素的影响,通常只能达到4M的长度。
4. Travel comparison: from the perspective of travel, the travel of linear guide depends on the stator and the rotor. Theoretically, the linear guide can be infinitely extended; However, the servo guide+screw rod can only reach the length of 4M due to the influence of the load, the outer diameter of the screw rod, the accuracy of different grades and other factors.
5、维护简单:直线轨道部件很少,没有接触,很少甚没有维护。滚珠丝杆结构有许多零件,需要经常维护或更换零件。
5. Simple maintenance: there are few components of linear track, no contact, little or no maintenance. The ball screw structure has many parts, which need to be maintained or replaced frequently.
6、寿命对比:
6. Life comparison:
直线导轨:由于运动部件和固定部件之间没有直接接触,所以即使长时间运行不改变运动精度,直线导轨也不会因动子的高速运动而磨损,因此使用寿命更长。
Linear guide rail: because there is no direct contact between moving parts and fixed parts, even if the movement accuracy is not changed after a long time of operation, the linear guide rail will not be worn due to the high-speed movement of the moving parts, so the service life is longer.
滚珠丝杆:滚珠丝杆由于高速运动而导致传动部件磨损,不能保证高速往复运动的精度,从而影响精度。
Ball screw rod: the ball screw rod causes wear of transmission parts due to high-speed motion, which can not guarantee the accuracy of high-speed reciprocating motion, thus affecting the accuracy.
