Raws li precision kis cov khoom sib kis, pob cov ntsia hlau yog dav siv hauv cov cuab yeej tshuab, cov cuab yeej siv tau, thiab lwm thaj teb. Qhov sib txuam ntawm lawv cov hmoov txhuas thiab thauj ncaj qha cuam tshuam rau kev ua haujlwm raug, ua tau zoo, thiab kev pabcuam lub neej ntawm cov khoom siv. Ib lub hom phiaj tsim nyog yuav ua rau muaj kev ua tau zoo ntawm kev xaav; Conversely, nws yuav ua rau muaj kev nce kev ua yuam kev, tiv thaiv kev tiv thaiv kom ceev dua, thiab lwm yam teeb meem. Kab lus no yuav piav qhia txog cov ntsiab lus tseem ceeb ntawm peb qhov: Cov ntsiab lus tseem ceeb, txuam cov ntsiab cai, thiab cov tswv yim siv tswv yim.
Nkag siab cov tub sab
Pob Pob Ntsia Hlau Ua
Lead hais txog qhov kev ncua deb uas cov txiv ntoo txav Axially rau kev sib hloov tag nrho ntawm cov ntsia hlau, ntsuas hauv millimeters (hli). Kev ua rau cov txiv ntseej loj dua hauv cov txiv ntseej ceev dua ntawm tib lub tig ceev, tab sis nws kuj nce qhov xav tau tsav lub zog. Ib qho kev ua me me, ntawm qhov tod tes, muab cov kis tau qhov tseeb thiab muaj zog thauj khoom dua- nqa muaj peev xwm. Cov kev qhia ua Lease LAFE, muaj xws li 4mm, 5 hli, thiab 10mm; Tsis - Txheem ua tau tuaj yeem kho tau rau cov xwm txheej tshwj xeeb.
Thauj hom thiab kev xam
Cov thauj khoom tsuas yog suav nrog axial thauj, radial thauj, thiab torque load, ntawm cov Axial thauj muaj qhov cuam tshuam loj tshaj plaws ntawm kev sib txuam. Axial thauj khoom yuav tsum tau xam raws li cov cuab yeej ua haujlwm, siv lub zog siv hluav taws xob, thiab lwm yam yog qhov loj ntawm kev hloov chaw, thiab yog qhov nrawm nrawm).
Cov ntsiab cai sib txuam
Kev sib npaug ntawm kev sib raug zoo ntawm kev thauj khoom thiab cov hmoov txhuas
Kev xaiv cov hmoov txhuas yuav tsum muaj kev sib npaug thauj khoom - nqa muaj peev xwm thiab kev khiav haujlwm ceev. Rau hnyav {{2} Cov khoom siv hluav taws xob (piv txwv li, hnyav {{5} yuav tsum tau muab rau pob screws nrog cov khoom me me. Lawv me xov cov ces kaum ua cov Axial thauj khoom khov kho {{} Nqa muaj peev xwm thiab txo qis torque ploj. Rau siab - ceev, lub teeb ceev nrawm dua, raws li lawv tuaj yeem ua tiav cov khoom siv nrawm dua thiab txhim kho kev ua haujlwm nrawm.
Kev sib koom tes kev sib koom tes ntawm precision thiab thauj khoom
Cov khoom siv precision (piv txwv li, cnc machining cov chaw) muaj cov phiaj xwm siab rau kev ua kom tiav thiab yuav tsum tau pob screws nrog cov khoom me me. Lawv cov kev tshem tawm me me rau ib txoj kev sib hloov ua rau kev tswj hwm ntau dua; Nyob rau tib lub sijhawm, hu rau kev ntxhov siab rau kev faib tawm me me {3} Taug txuj ci yog ntau yam kev sib tw, tso cai siab} precision kev ua haujlwm nyob rau hauv qee yam load. Yog tias ob leeg hnyav {{6} log thiab siab {- Precision cov qhab nia qhab nia (piv txwv li qib C1, C3) thiab ua kom zoo rau cov qauv kev txhawb nqa.
Cov tswv yim txuam
Xaiv cov ua raws li kev thauj khoom ntau
- Thaum lub axial load f tsawg dua lossis sib npaug nrog 5000n, screws nrog cov hmoov txhuas ntawm 5-10 hli tuaj yeem siv los sib npaug ntawm kev ceev thiab raug.
- Rau kev thauj khoom thaum 5000n thiab 15000n, ib tug lead ntawm 4 {- 6mm yog pom zoo kom txhim kho load-nqa muaj peev xwm.
- Rau cov khoom siv> 15000n, screws nrog cov hmoov txhuas tsawg dua 4 hli yuav tsum tau siv, sib xyaw ua ke nrog ob npaug- cov txiv qauv los txhim kho nruj.
Kho cov txhuas raws li kev ua haujlwm nrawm
When the rated motor speed n is fixed, the nut speed is calculated as v=Lead P × n / 60. If the equipment requires high-speed operation, the lead can be increased, but it is necessary to verify whether the motor torque meets the load requirements. Piv txwv li, lub cev muaj zog torque t yuav tsum txaus siab t}} f ×) (feem ntau yog cov kev ua haujlwm jamming vim tsis muaj zog torque.
Txhim kho cov kev txuam nrog cov kev ua haujlwm tshwj xeeb
Cov khoom siv nrog cov pib nquag -}}}} Cov screats kom txo cov kev cuam tshuam ntawm inertial kev poob siab ntawm lub nra. Rau cov khoom siv ua ke tsis tu ncua ntev ntev rau cov sijhawm ntev, nws yog qhov tsim nyog los tiv thaiv tshav kub ntau dhau los thaum muaj kev kub ntxhov dhau los ntawm loj {4} Taug txuj kev nyuaj. Tsis tas li ntawd, rau cov plua plav tsis muaj plua plav
Zam kev tsis to taub
Qee tus neeg siv ua yuam kev ntseeg tias kev ua tau loj dua txhais tau tias muaj zog load - nqa muaj peev xwm. Qhov tseeb, qhov rov qab yog qhov tseeb: Pob screws nrog cov loj ua tau loj xov cov ces kaum kev loj, ua rau muaj peev xwm nqa tau thiab muaj kev pheej hmoo ntawm deformation. Tsis tas li ntawd, tsis quav ntsej txog kev suav ntawm inertial load tuaj yeem ua rau muaj kev sib txawv; Nws yog ib qho tsim nyog kom muaj kev nkag siab txog cov lej ntawm kev ua haujlwm thauj, inertial thauj khoom, thiab kev sib txhuam load.
Hauv kev xaus, qhov sib txuam ntawm pob ntsia hlau ua thiab thauj khoom yuav tsum yog kev nkag siab ntawm cov qauv tseem ceeb, ua raws li kev txiav txim siab ua haujlwm thiab ua haujlwm kev txiav txim siab ua haujlwm rau kev txiav txim siab {}}} ua. Ib lub phiaj xwm sib piv tsim nyog tuaj yeem muab tag nrho cov kev sib kis tau zoo rau cov pob khoom sib kis ntawm pob ntsia thiab txhim kho cov kev ua tau zoo thiab kev pabcuam lub neej ntawm cov khoom siv.
