Cov lus piav qhia luv luv thiab cov qauv tsim qauv piav qhia ntawm cov kab hluav taws xob zawv zawg:
◎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.
Cov kab hluav taws xob zawv zawg tau muab faib ua ib lub pob square linear zawv zawg chav tsev, ob chav -axis core roller linear sliding unit, thiab ib qho -axis core linear sliding unit.
Hauv av loj, nws yog hu ua linear slide unit, thiab nyob rau hauv Taiwan nws yog feem ntau hu ua linear qhia los yog ib tug linear swb.
Lub luag haujlwm ntawm daim ntawv qhia kev tawm suab yog los txhawb thiab coj cov kev txav mus los ua ib qho kev sib txuas lus tawm hauv ib qho kev taw qhia. Nyob ntawm qhov xwm txheej ntawm kev sib txhuam, cov kev taw qhia tawm txoj kab tuaj yeem muab faib ua zawv zawg kev sib txhuam cov lus qhia, dov kev sib txhuam cov lus qhia, cov lus qhia kev sib txhuam elastic, thiab cov dej sib txhuam cov lus qhia.
◎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.
Cov ntawv qhia kev tsheb ciav hlau raws li cov lus qhia yog cov hlau tawv tawv, uas tau muab tso rau ntawm lub dav hlau installation tom qab kev sib tsoo zoo. Muab piv nrog cov kev taw qhia tiaj tus, tus ntoo khaub lig-sectional geometry ntawm linear sliding units yog qhov nyuaj dua li cov lus qhia tiaj tus. Yog vim li cas rau qhov nyuaj yog tias grooves yuav tsum tau machined ntawm cov lus qhia rails los pab txhawb kev txav ntawm zawv zawg ntsiab. Cov duab thiab tus naj npawb ntawm cov grooves nyob ntawm qhov yuav tsum tau ua ntawm lub tshuab cuab yeej. Ua tiav kev ua haujlwm. Piv txwv li: Ib qho kev qhia kev tsheb ciav hlau uas dais ob qho tib si linear force thiab subversive lub sij hawm yog muab piv nrog cov kev taw qhia kev tsheb ciav hlau uas tsuas yog bears linear force. Cov qauv tsim txawv heev.
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.
Yog tias lub sijhawm ua haujlwm ntev dhau lawm, lub pob steel pib hnav, thiab lub preload ntawm lub pob steel pib tsis muaj zog, uas ua rau txo qis qhov tseeb ntawm qhov ua haujlwm ntawm lub tshuab cuab yeej. Yog tias koj xav kom tswj tau qhov tseeb thawj zaug, koj yuav tsum hloov lub rail bracket, lossis txawm hloov lub tsheb ciav hlau. Yog hais tias lub rail system muaj preload nyhuv. Qhov tseeb ntawm qhov system tau ploj lawm, thiab tib txoj kev yog los hloov cov khoom dov.
Kev tsim qauv ntawm kev taw qhia kev tsheb ciav hlau sib zog ua kom muaj qhov chaw sib txuas loj tshaj plaws ntawm cov khoom ruaj khov thiab cov khoom txav. Qhov no tsis tsuas yog txhim kho lub peev xwm nqa ntawm lub cev, tab sis kuj tseem tuaj yeem tiv thaiv qhov cuam tshuam ntawm lub zog uas tsim los ntawm kev sib tshuam txiav los yog lub ntiajteb txawj nqus txiav, nthuav tawm lub zog dav, thiab nthuav dav lub peev xwm. Thaj tsam ntawm lub zog. Yuav kom ua tiav qhov no, muaj ntau yam groove duab rau cov kev taw qhia rail system. Muaj ob tus neeg sawv cev. Ib qho yog hu ua Gedai hom (taw taw koov hom), cov duab yog qhov txuas ntxiv ntawm ib lub voj voog, thiab qhov chaw sib cuag yog lub apex; lwm yam Cov hom yog arc-zoo li tus thiab tuaj yeem ua si tib lub luag haujlwm. Tsis muaj teeb meem dab tsi ntawm cov qauv, tsuas yog ib lub hom phiaj, thiab siv zog kom muaj ntau dua dov steel pob vojvoog sib cuag nrog cov lus qhia rail (taw lub caij). Qhov tseem ceeb uas txiav txim siab qhov kev ua tau zoo ntawm qhov system yog: yuav ua li cas cov ntsiab lus dov hu rau cov kev taw qhia rail, uas yog tus yuam sij rau qhov teeb meem.
