直線導(dǎo)軌系統(tǒng)的固定元件起什么作用?以下導(dǎo)軌絲杠公司小編將為您解答:
What is the function of the fixed elements of the linear guide system? The following guide screw company will answer for you:

直線導(dǎo)軌主要用于精度高的機(jī)械結(jié)構(gòu)中,直線導(dǎo)軌的移動(dòng)元件和固定元件之間的介質(zhì)不是,而是用鋼球滾動(dòng)。因?yàn)闈L鋼球適用于高速運(yùn)動(dòng),摩擦系數(shù)小,靈敏度高,能滿足運(yùn)動(dòng)部件的工作要求,如機(jī)床刀架、拖板等。如果作用在鋼球上的力過(guò)大,鋼球?qū)⒊惺芴L(zhǎng)時(shí)間的預(yù)壓,導(dǎo)致支座運(yùn)動(dòng)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.
直線導(dǎo)軌系統(tǒng)(導(dǎo)軌)的固定元件具有承重環(huán)的基本功能,安裝鋼球的支架呈“v”形。支架覆蓋導(dǎo)軌的頂部和兩側(cè)。為了支撐機(jī)器的工作部件,一套直線導(dǎo)軌少要有四個(gè)支架。對(duì)于大的工作部件,支架的數(shù)量可以超過(guò)4個(gè)。
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.
機(jī)床工作部件移動(dòng)時(shí),鋼球在支架槽內(nèi)循環(huán),支架的磨損分布到每個(gè)鋼球上,從而延長(zhǎng)直線導(dǎo)軌的使用壽命。為了支架與導(dǎo)軌之間的間隙,預(yù)加載可以提高導(dǎo)軌系統(tǒng)的穩(wěn)定性,獲得預(yù)加載。在導(dǎo)軌與支架之間安裝特大號(hào)鋼球。鋼球的直徑公差為±20微米,增加0.5微米。鋼珠經(jīng)過(guò)篩選和分類,分別安裝在導(dǎo)軌上。預(yù)加載的大小取決于作用在鋼球上的力。如果作用在鋼球上的力過(guò)大,預(yù)壓時(shí)間過(guò)長(zhǎng),導(dǎo)致支座運(yùn)動(dòng)阻力增大,就會(huì)出現(xiàn)平衡效果問(wèn)題;為了提高系統(tǒng)的靈敏度和減小運(yùn)動(dòng)阻力,需要相應(yīng)地減小預(yù)緊力,為了提高運(yùn)動(dòng)精度和維護(hù)精度,需要有足夠的負(fù)預(yù)緊力,這是兩個(gè)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.
