Kev xaiv cov khoom sib piv rau cov kab kev tawm yog qhov tseem ceeb rau kev ua kom ua tau zoo rau cov kev taw qhia kev ua haujlwm. Linear bushings tau muab faib ua pob bushings thiab rab koob bushings: Pob bushings siv cov ntawv xov xwm ceev (linear ceev txog li 5m / s) thiab lub teeb rau nruab nrab loads; Koob nuj txeeg Bushings siv cov cylindrical koob muaj peev xwm (2 {}}}}} 3 / s), zoo tagnrho rau cov khoom siv hnyav-xws li nias MACHINE.
Support units are essential for shaft fixing and alignment. Fixed side support units (e.g., type LMF) feature set screws or lock nuts to secure the shaft axially, preventing movement during operation. Floating side support units (e.g., type LMC) allow slight axial movement of the shaft, compensating for thermal expansion (linear shafts expand by approximately 11.7×10⁻⁶/°C, so a 1m long shaft heated by 50°C will expand by 0.585mm). For long shafts (length >1500 hli), cov chav txhawb pab nruab nrab yuav tsum tau ntxiv rau txhua 800-1000mmM los tiv thaiv sagging thiab paub tseeb.
Cov kev teeb tsa tau teeb meem tseem ceeb cuam tshuam qhov kev ua tau zoo ntawm txoj kab rov tav. Parallelelism yuam kev nruab nrab ntawm ob txoj kev sib tw sib txuas yuav tsum tau tswj tsis pub dhau 0.02-0.05mm / m; Kev sib txhuam ntau dhau rau kev sib txhuam ntau dhau ntawm tus ncej thiab bushing, ua rau lub suab ua ntej ua haujlwm thiab nce lub suab nrov. Coaxiality yuam kev thaum txuas ntau cov hlau yuav tsum tsis pub tshaj 0.03mm; Kev ua kev tsis yog neeg tuaj yeem ua rau muaj kev sib tw radial, txo cov kev nqa cov ciaj sia los ntawm 30-50%.
Txhawm rau tswj cov kev teeb tsa, cov kauj ruam hauv qab no yuav tsum tau kho cov txheej txheem ntawm RA Kev ua kom zoo nkauj thiab coaxiality, kho cov kev txhawb nqa nrog shims yog tias tsim nyog {{
Ib qho ntxiv, lubrication thiab kev tiv thaiv yog qhov tseem ceeb rau kev tswj cov kev ua haujlwm system. Leatar Shafts thiab bushings yuav tsum tau lubricated nrog lithium - Raws li cov roj txhua 100-200 sijhawm ua haujlwm; Hauv cov plua plav ib puag ncig, cov txiv mis uas muaj roj nrog cov hmoov av cap yuav tsum tau siv los tiv thaiv kev sib kis. Rau cov ntawv thov muaj cov dej noo siab lossis cov kua muaj roj corrosive, lub telescopic tiv thaiv npog lossis cov neeg muag khoom yuav tsum muab cov ntaub qhwv rau ntawm kev sib chwv nrog paug. Kev tshuaj xyuas ib txwm ntawm tus ncej rau cov khawb av rau cov khawb lossis kev hloov pauv ntawm cov kev taw qhia raws sijhawm tuaj yeem ua raws li cov kev taw qhia kev ua haujlwm ruaj khov rau lub sijhawm ntev.
