Tawm guides rau lawv tus kheej txhais tes

Profile linear ntawm cov, nrog lawv txhais tes ua, los yog muas - ib tug menyuam los yog pob precision bearings, pab nyob rau hauv linear taw. Lawv muaj peev xwm paub cov rog kuj nyob rau hauv tag nrho cov lus qhia tsuas yog cov kev taw qhia ntawm lub zog.

Hom linear ntawm cov

Tawm ntawm cov yog ob hom:

• recirculating pob kabmob;
• recirculating cov menyuam.

Pob ntawm cov ua ob, four- thiab rau-kab. Lawv yog cov tej yam me me, haum rau kev siv nyob rau hauv txwv installation qhov chaw. Lub linear ntawm cov no yog ua los nrog sib txawv drives. Ntawm lawv yog cov ntau ntau toothed siv tsav los yog pob ntsia hlau (pob screws).

Kev uas quav tua nyob rau hauv daim ntawv ntawm cylindrical qhia ntsia thiab tiaj tawb.

Tag nrho cov ntawm cov yuav tsum tau muaj cov yam ntxwv tseem ceeb:

• tsawg kev sib txhuam;
• high efficiency;
• tus linear zog;
• muaj peev xwm tswj tau cov kev khiav hauj lwm tsis.

Modules linear xaav

Tsis ntev los no, nyob rau hauv kev twb kev txuas nrog cov automation ntawm txoj kev loj hlob ntawm tseem ceeb heev rau txoj kev siv cov modules muas linear tsab ntawv tsa suab, uas muaj xws li:

• khoom cab kuj profile;
• muaj tseeb qhia system;
• check tsav mechanism;
• Servomotor nrog tej yam yooj yim ntawm lwm yam uas.

Nyob rau hauv xws li ib tug modular tivthaiv xyuas daim ntawv thov raws li ib daim ntawv qhia-kev coj tus kheej cov khoom thiab cov kabmob clips. Ua hauj lwm yog tsav los ntawm ib tug linear lub cev muaj zog, ib tug toothed siv los yog ib lub pob ntsia hlau mechanism.

Tau ua ntawv thov thiab linear ntxhuav, siv thaum tsim nyog rau koj tsiv loj masses ntawm tus axes. Vim loj, lawv coj zoo lub sij hawm ntawd loads. Lub linear ntxhuav yog siv:

• linear zog ntawm lub tes tsho;
• recirculating pob tau cov kabmob.

Txoj kev xab raug

Yog hais tias koj yuav ua li linear ntawm cov nrog lawv tus kheej txhais tes, koj yuav tau tswj cov neeg. Qhov no yog ua heev tsuas. Mounted rau ib lub hauv paus nto yog muab tso rau hauv lub tsheb nqaj hlau. Nyob rau hauv cov ntaub ntawv no, cov neeg - ib qho kev qhia ntawm qhov nruab nrab tus nqi ntawm lub ntsuas no yog qhov nyob rau hauv lub central ib feem ntawm qhov chaw yuav tsum tau ntsuas. Tsis tas li ntawd precision linear Phau ntawv no yog txiav txim los ntawm ntsuas qhov dav thiab ntev. Thaum zoo li no kam yog ntsuas los ntawm qhov luaj li cas ntawm txhua lub block uas yog mounted rau cov kev tsheb nqaj hlau.

Rigidity thiab preload

Thaum lub sij hawm kev lag luam, profile rail ntawm cov raug, vim lub applied load, cov teebmeem ntawm elastic ntaub ntawv. Indications nqi ntawm deformation nyob ntawm lub hom ntxuag caij. Tab sis rau nkawv noj, nws yuav me me thaum lub load nce.

Yuav kom nce lub rigidity ntawm lub system thov preload. Nws thiaj li lub neej ntawm cov linear ntawm cov, yuav ua tau rau sab hauv kev nyuaj siab nyob rau ntawd, tab sis muaj peev xwm sawv ntawm deforming yuav nqus loads nyob rau hauv lub linear phau ntawv nyob rau hauv tej yam kev mob ntawm kev mob loj co los yog poob siab loads. Vim lub fact tias cov preload ua elastic deformation ntawm lub kabmob, lawv ua nyob rau hauv lub tej yam tsis zoo ntawm cov installation kev ua yuam kev. Qhov no qhia tau hais tias ntau mloog yuav tsum tau them rau cov neeg ntawm cov zauv rau lub mounting nto.

Hom preload:

• Qhov - yog siv nyob rau hauv lub xub ntiag ntawm me ntsis kev co;
• lub teeb - siv nyob rau hauv lub xub ntiag ntawm lub teeb deeg thiab torque;
• nruab nrab - siv rau poob siab loads thiab muaj zog deeg, raws li zoo raws li tipping load.

Mounting ntsia

Nws yog ib qho tseem ceeb kom paub hais tias lub linear phau ntawv ntsia raug rog thiab torque. Rau lawv, tus nqi yuav tsum tau txiav txim: permissible zoo li qub torque thiab load peev xwm, uas yog xam siv cov qauv. Suav ntsuam xyuas lub neej ntawm lub pob thiab cov menyuam ntawm cov, nws yog tsim nyog los siv ib tug txawv mis.

Nyob rau ib lub qhov stroke ntev thiab zaus ntawm lub zog ntawm kev pab cuam lub neej yog qhia los ntawm lub sij hawm. Nrog nws cov kev cog lus ntawm mounting qhov ntev, profile rail ntawm cov muaj lub siab load peev xwm. Ntsia tau rau hauv ntau hom tshuab cov cuab yeej los yog lwm yam khoom siv, lawv yog mounted nyob rau hauv ob txoj kev sib txawv: nyob rau hauv daim ntawv ntawm ib tug kab rov tav rail thiab sab mounting txoj kev.

Txij li thaum cov khoom no yog ua los ntawm ob tug uas tig mus ntsia, thawj rail kev kho sau rau hauv lub hauv paus sab, thiab lwm yam - nyob rau sab adjustable.

Thaum ua hauj lwm nrog loj poob siab loads thiab deeg ntxiv sab qhov chaw - sab ntawm lub siab phaj, cov mounting ntawm ntev screws, lub conical npoo - tswj lawv tshem tawm.

Txhim kho lub ntxiv clamping qhov chaw nyob rau hauv qhov uas tsis muaj-load thiab tsawg velocities xaav yog tsis yuav tsum tau.

Tawm kev taw qhia rau CNC tshuab cov cuab yeej

Yuav ua li cas yog lub system ntawm linear xaav? Nws yog ib tug ua ke ntawm kis tau tus mob thiab linear ntawm cov.

Tawm kev taw qhia rau CNC - yog linear bearings, bushings, shafts. Lawv tus kheej raws li ntawm cov yuav tsum hais peb lub ntsiab hom phiaj:

• yuav ib tug them nyiaj yug rau lub tshaaj ntawm lub tshuab;
• nrog yam tsawg kawg nkaus kev sib txhuam, nrog rau yuav tsum tau raug mus rau lub kev kawm txog kev yuav muab lub zog ntawm lub tshuab qhov chaw;
• noj cov kev nyuaj siab tshwm sim los thaum lub sij hawm ua hauj lwm cov txheej txheem.

Tawm ntawm cov raug muab faib raws li ib txoj kev ntawm fastening mus rau lub tshuab. Qhov no daim ntawv qhia uas muaj tag nrho cov kev pab txhawb nqa - cov qauv ntawm cov txuas mus rau lub thav duab ntawm lub tag nrho ntev ntawm phau ntawv no, thiab ib nrab them nyiaj yug - txoj kev ntawm txuas ntawm lub kawg.

Phau Ntawv Qhia nrog rau tag nrho cov nyiaj them yug muaj ib tug ntau dua muaj peev xwm, raws li txwv mus rau ntsia nrog ib nrab them nyiaj yug. Tej zaum kuj muaj kev xaiv thaum lub axes teem linear ntawm cov - ob qho tag nrho tag nrho thiab yog ib feem-kho.

Cov neeg sawv cev ntawm tej pab pawg yog linear shafts. Lawv nqa tawm tau ntawm kev siv ob peb hom cylindrical ntawm cov:

• polished qhia shafts - yog lub feem ntau (high muaj, yooj yim ntawm installation);
• splined shafts - lub siab coj kuj thiab toughness, muaj peev xwm ntawm kev txiav txim siab-torsional rog ntawm lub hub. Siv nyob rau hauv lub davhlau ya nyob twg mounting ntsia;
• ntoo nyob rau hauv ib tug them nyiaj yug - ib tug cylindrical ntsia. Lawv yog siv nyob rau hauv daim ntawv ntawm ncaj qha Symptoms rau lub tshuab.

Cov neeg ntawm lub mounting nto

Profiled ntsia ntsia siv mounting rau lub kho nto ntawm lub hauv paus. fastening txoj kev yog mus muab ib tug poob rau ntawm lub rooj nto tsim thereon nyob rau hauv lub puag nto los yog lub carriage. Exception distortions tau nyob rau hauv lub xub ntiag ntawm lub zawj nyob rau hauv lub ces kaum ntawm lub ntseg tsho.

Yog ib tug tib sib raug zoo ntawm cov kev tsheb nqaj hlau nto raug thiab precision ntawm lub zog. Nyob rau qhov no yuav yog nyob ntawm seb cov neeg ntawm tag nrho cov khoom. Cov neeg ntawm lub machined mounting nto sau raws nkaus Ii lub teev raug yuav tsum xaav. Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias nws yog tsim nyog los noj account ntawm lub flatness ntawm lub tsev, tsis suav lub carriage deformation.

puag nto

Yuav kom muab ntau yog thiab yooj yim installation, nws yog tsim nyog los tsim ib lub hauv paus nto yuav tsum tau npaj rau lub carriage thiab nyob rau hauv kev tsheb nqaj hlau rau ntawm ib sab.

Yog li ntawm daim ntawv lo yuav tsum tau positioned nyob rau sab nraud. Yog hais tias txaus cov neeg no tsis yog ensured vim lub peculiarities mounting tswvyim, whereas ua yog ua nrog yooj yim chaw thiab lub thib ob sab.

Corrosion tiv thaiv thiab lubrication

Yuav kom tiv thaiv cov ntsia los ntawm cov teebmeem ntawm xeb, lawv hu nkauj los ntawm stainless hlau. Muaj yog ib tug variant nrog rau daim ntawv thov ntawm cov tshwj xeeb kev tiv thaiv txheej. Nws daim ntawv thov yog nqa tawm, yog hais tias tsim nyog nyob rau hauv ib tug high degree ntawm kev tiv thaiv tiv thaiv corrosion.

Ntawm cov npaj txhij Hoobkas-lubricated nrog roj, ua rau lub hauv paus ntawm lithium xab npum. Tom qab hais tias, lawv yuav siv tau rau lwm yam hom phiaj. Ntau yam kev khiav hauj lwm tej yam kev mob yuav tsum tau tas li ntawd ntawm lubricant tsim nyog periodicity ntawm tib hom.
