简单介绍一下直线导轨的优点及特点

在一般的直线导轨滑块和滑轨,钢珠滑块可以无限循环滚动的导轨与滑块之间可沿平台滑动,易负载高精度直线运动,与传统的滑动导轨和滚动导轨的摩擦系数相比可减少到原来的1/50,所以直线导轨可以达到更高的精度和传动效率。此外,直线导轨的定位精度和传动精度高,传动损耗小,精度可长期保持,直线导轨的使用寿命也得到提高。


直线导轨可应用于低转速也可以用在高速度,具有很高的承载力,以直线导轨运动形式的滚动摩擦,摩擦力很小,只有一个很小的力就可以使负载滑动操作,特别是在通勤手术床的工作,可降低能耗,提高效率。


由于直线滑轨的特殊设计结构,它能同时承受上、下、左右的载荷。与滑动导轨不同,它只能在平行接触面上承受较大的载荷。


直线导轨、直线导轨安装面可通过铣磨加工得到装配和互换性。但是,当导轨精度要求较高时,导轨安装面的加工精度相对较高。该直线导轨具有互换性,可分别改变滑块或滑轨。更换零件后,机构可恢复较高的运动精度。


在使用直线导轨时,特别是在高负荷、不间断和往复运动时,应注意滑轨和导轨的润滑,这将大大影响润滑条件下直线导轨的使用寿命和精度。


In general the linear guide slider and rail, steel ball slider can infinite rolling cycle between the slide rail and the slide block can slide along the platform, load easily with high precision linear motion, compared with the traditional sliding guide and rolling guide friction coefficient can be reduced to the original 1/50, so the linear guide track can reach more high precision and transmission efficiency. In addition, the positioning and transmission precision of the straight line rail is high, the drive wear is less, the precision can be maintained for a long time, and the service life of the linear guide is also improved.

The linear guide can be applied to low speed can also be used in high speed, and has high bearing capacity, at the same time as the linear guideway movement form rolling friction, friction movement is very small, only a small force can make the load slide operation, especially in bed work for commuter operation, it is able to significantly reduce the energy consumption, improve efficiency.
Due to the special design structure of straight slide rail, it can bear the load of the upper, the lower, the left and the right at the same time. Unlike sliding guidance, it can only carry large loads on the parallel contact surface.

The assembly and interchangeability of the linear guide rail, the installation surface of the linear guide rail can be obtained by milling and grinding. However, when the guiding accuracy requirement is relatively high, the machining accuracy of the guide rail mounting surface is relatively high. The linear guide rail has interchangeability and can change the slider or the slide rail respectively. After the replacement of the components, the mechanism can restore the higher motion precision.

When using linear guideway, especially in high load, uninterrupted and reciprocating motion, we should pay attention to lubrication of slide and slide rail in time, which will greatly affect the service life and accuracy of linear guide rail under the condition of insufficient lubrication.
