  直线导轨系统的固定元件起什么作用?以下导轨丝杠企业小编将为您解答:
  What is the function of the fixed elements of the linear guide system? The following guide screw company will answer for you:
导轨丝杠
  直线导轨主要用于精度高的机械结构中,直线导轨的移动元件和固定元件之间的介质不是,而是用钢球滚动。因为滚钢球适用于高速运动,摩擦系数小,灵敏度高,能满足运动部件的工作要求,如机床刀架、拖板等。如果作用在钢球上的力过大,钢球将承受太长时间的预压,导致支座运动阻力增大。
  The linear guide is mainly used in the mechanical structure with high precision. The medium between the moving element and the fixed element of the linear guide is not steel ball rolling. Because the rolling ball is suitable for high-speed movement, with small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as machine tool holder, carriage, etc. If the force acting on the ball is too large, the ball will bear the preload for too long, which will increase the resistance of the support movement.
  直线导轨系统(导轨)的固定元件具有承重环的基本功能,安装钢球的支架呈“v”形。支架覆盖导轨的顶部和两侧。为了支撑机器的工作部件,一套直线导轨至少要有四个支架。对于大的工作部件,支架的数量可以超过4个。
  The fixed element of the linear guide system (guide rail) has the basic function of the bearing ring, and the bracket for installing the steel ball is in the shape of "V". The bracket covers the top and both sides of the rail. In order to support the working parts of the machine, a set of linear guide rails must have at least four supports. For large working parts, the number of supports can exceed 4.
  机床工作部件移动时,钢球在支架槽内循环,支架的磨损分布到每个钢球上,从而延长直线导轨的使用寿命。为了消除支架与导轨之间的间隙,预加载可以提高导轨系统的稳定性,获得预加载。在导轨与支架之间安装特大号钢球。钢球的直径公差为±20微米,增加0.5微米。钢珠经过筛选和分类,分别安装在导轨上。预加载的大小取决于作用在钢球上的力。如果作用在钢球上的力过大,预压时间过长,导致支座运动阻力增大,就会出现平衡效果问题;为了提高系统的灵敏度和减小运动阻力,需要相应地减小预紧力,为了提高运动精度和维护精度,需要有足够的负预紧力,这是两个相互矛盾的方面。
  When the working parts of the machine tool move, the steel ball circulates in the bracket groove, and the wear of the bracket is distributed on each steel ball, thus prolonging the service life of the linear guide rail. In order to eliminate the gap between the bracket and the guide rail, preloading can improve the stability of the guide rail system and obtain preloading. Install extra large steel ball between guide rail and bracket. The diameter tolerance of the steel ball is ± 20 microns, with an increase of 0.5 microns. The steel balls are screened and classified and installed on the guide rails respectively. The amount of preload depends on the force acting on the ball. If the force acting on the steel ball is too large and the preloading time is too long, which leads to the increase of the resistance of the support movement, the balance effect problem will appear; in order to improve the sensitivity of the system and reduce the resistance of the movement, the preload needs to be reduced correspondingly, and in order to improve the accuracy of the movement and maintenance, there needs to be enough negative preload, which are two contradictory aspects.
