Yon entwodiksyon tou kout ak deskripsyon konsepsyon sistèm nan inite glisman lineyè a:
◎Linear sliding units are also called linear rails, sliding rails, linear guides, linear sliding rails. They are used in linear reciprocating motion applications. They have a higher rated load than linear bearings, and can bear a certain torque at the same time, which can be used under high load conditions. Realize high-precision linear motion.
Inite glisman lineyè a divize an yon inite glisman lineyè boul kare, yon inite glisman lineyè aks-double aks, ak yon sèl inite glisman lineyè aks-.
Nan tè pwensipal la, yo rele sa yon inite glise lineyè, ak nan Taiwan li jeneralman yo rele yon gid lineyè oswa yon glise lineyè.
Fonksyon gid mouvman lineyè a se sipòte ak gide pati k ap deplase yo pou fè yon mouvman lineyè resipwòk nan yon direksyon. Tou depan de nati friksyon an, gid mouvman lineyè ka divize an gid friksyon glisman, gid friksyon woule, gid friksyon elastik, ak gid friksyon likid.
◎Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc., of course, linear bearings and linear shafts are used together. Linear sliding units are mainly used for accuracy requirements comparison On the high mechanical structure, the slider-makes the movement change from a curve to a straight line. The new guide rail system enables the machine tool to obtain rapid feed speeds. In the case of the same spindle speed, rapid feed is the characteristic of the linear sliding unit. The linear sliding unit is the same as the flat guide rail. It has two basic elements; one as a guide is a fixed element, and the other is a moving element. Since the linear sliding unit is a standard component, it is a machine tool manufacturer. The only thing to do is to process the plane of a mounting rail and adjust the parallelism of the rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential. In most cases, the installation is relatively simple.
Rail la gid kòm gid la se asye fè tèt di toujou, ki se mete sou avyon an enstalasyon apre amann fanm k'ap pile. Konpare ak ray gid plat, jeyometri kwa-seksyonèl inite glisman lineyè a pi konplèks pase ray gid plat. Rezon ki fè la pou konpleksite a se ke genyen siyon bezwen yo dwe machin sou ray yo gid fasilite mouvman an nan glisman eleman. Fòm ak kantite genyen siyon depann sou kondisyon zouti machin lan. Konplete fonksyon. Pou egzanp: Yon sistèm tren gid ki pote tou de fòs lineyè ak moman sibvèsif yo konpare ak yon tren gid ki pote sèlman fòs lineyè. Konsepsyon an trè diferan.
There is no intermediate medium between the moving element and the fixed element of the linear sliding unit, but a rolling steel ball. Because the rolling steel ball is suitable for high{{0}}speed motion, has a small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the tool holder and carriage of the machine tool. The basic function of the fixed element (guide rail) of the linear sliding unit system is like a bearing ring. The bracket for mounting the steel ball is shaped like a "v". The bracket wraps the top and both sides of the rail. In order to support the working parts of the machine tool, a set of linear sliding unit has at least four supports. Used to support large working parts, the number of brackets can be more than four. When the working parts of the machine tool move, the steel balls circulate in the groove of the bracket, and the wear of the bracket is distributed to each steel ball, thereby prolonging the service life of the linear sliding unit. In order to eliminate the gap between the bracket and the guide rail, the preload can improve the stability of the guide rail system and the preload can be obtained. It is to install an oversized steel ball between the guide rail and the bracket. The diameter tolerance of the steel ball is ±20 microns, with 0.5 micron increments. The steel balls are screened and classified and installed on the guide rails respectively. The size of the preload depends on the force acting on the steel balls. If the force acting on the steel ball is too large, the steel ball will withstand the preload for too long, which will increase the movement resistance of the bracket. There is a balance problem here; in order to improve the sensitivity of the system and reduce the movement resistance, the preload must be reduced accordingly, and in order to improve the movement accuracy and the retention of precision, it is required to have sufficient preload negative numbers, which are contradictory two. aspect.
Si tan an k ap travay twò lontan, boul la asye kòmanse mete, ak prechaj la sou boul la asye kòmanse febli, sa ki lakòz yon diminisyon nan presizyon nan mouvman nan pati pyès sa yo k ap travay nan zouti nan machin. Si ou vle kenbe presizyon inisyal la, ou dwe ranplase bracket tren an, oswa menm ranplase tren an. Si sistèm tren an gen yon efè prechaj. Presizyon nan sistèm lan te pèdi, ak sèl fason se ranplase eleman yo woule.
Konsepsyon sistèm tren gid la fè efò pou gen pi gwo zòn kontak ant eleman fiks ak eleman k ap deplase a. Sa a pa sèlman amelyore kapasite pote nan sistèm nan, men tou, sistèm nan ka kenbe tèt ak fòs la enpak ki te pwodwi pa koupe tanzantan oswa koupe gravite, gaye fòs la lajman, ak elaji kapasite a pote. Zòn nan fòs. Yo nan lòd yo reyalize sa a, gen divès fòm Groove pou sistèm nan tren gid. Gen de reprezantan. Youn yo rele kalite Gedai (tip vout pwente), fòm nan se ekstansyon yon semicircle, ak pwen kontak la se APEX la; lòt la Espès la gen fòm arc-e li kapab jwe menm wòl la tou. Pa gen pwoblèm ki kalite estrikti, gen yon sèl objektif, epi fè efò yo gen plis woule asye boul reyon kontak ak tren an gid (eleman fiks). Faktè ki detèmine karakteristik pèfòmans yo nan sistèm nan se: ki jan eleman yo woule kontakte tren gid la, ki se kle nan pwoblèm nan.
