Lub luag haujlwm tseem ceeb ntawm cov yeeb nkab txhawb nqa suav nrog kev txhawb nqa qhov hnyav ntawm cov kav dej, txwv tsis pub cov yeeb nkab hloov chaw, tsis muaj kev vibration thiab cuam tshuam, thiab ua kom haum rau thermal expansion thiab contraction.
Lawv cov qauv feem ntau muaj peb ntu: lub hauv paus, cov khoom txhawb nqa, thiab kho cov khoom siv. Lub hauv paus ncaj qha hu rau lub hauv paus nto, muab kev txhawb nqa ruaj khov; cov khoom txhawb nqa tau tsim raws li cov yeeb nkab tshwj xeeb kom faib cov khoom ntsug; thiab kho cov khoom siv (xws li bolts thiab clamps) nruj nreem txuas cov yeeb nkab rau kev txhawb nqa, tiv thaiv slippage lossis detachment.
Raws li cov ntaub ntawv, cov yeeb nkab txhawb nqa tuaj yeem ua los ntawm carbon steel, stainless hlau, PTFE, thiab lwm yam, nyob ntawm qhov chaw ua haujlwm, kom ua tau raws li qhov yuav tsum tau muaj xws li corrosion kuj, kub tsis kam, los yog rwb thaiv tsev.
