Cov ntsiab lus
1. Kev faib tawm los ntawm hom kev ua kis las
Radial articulated bearings: Feem ntau tsim los tiv thaiv radial loads perpendicular rau axis, thiab tuaj yeem tig ib ncig ntawm axis thiab qaij nyob rau hauv lub kaum sab xis. Qhov no yog hom tshaj plaws.
Daim ntawv thov: Txuas pas nrig mechanism, qib fulcrum.
Angular hu sib koom bearings: muaj peev xwm ntawm cov kabmob ob leeg radial thiab unidirectional axial (thrust) loads.
Daim ntawv thov: Viav caj npab kom tiv taus thrust, kiv cua txhawb nqa.
Thrust joint bearings: Tshwj xeeb tsim los tiv thaiv cov axial nkaus xwb raws li cov kev taw qhia axial thiab tso cai rau kev sib tw me ntsis.
Daim ntawv thov: ntsia hlau crane, loj ntsug twj tso kua mis.
Qws kawg kev sib koom ua ke: Lub nplhaib sab hauv lossis sab nraud ntawm cov kabmob sib koom ua ke nrog cov hlua khi hlua kawg lub cev los ua kom tiav cov kev hloov pauv - cov khoom. Nws tau muab faib ua "txiv neej threaded pas nrig kawg" (ntiv nplhaib nrog xov) thiab "poj niam threaded pas nrig kawg" (lub nplhaib puab nrog xov).
Daim ntawv thov: Push- rub tswj kev sib txuas, lub kauj hlua khi, kev sib txuas actuator.
2. Kev faib tawm los ntawm zawv zawg cov khoom siv nto thiab tsim (qhov no yog qhov tseem ceeb ntawm kev xaiv)
Hlau rau Hlau Hom:
Structure: Cov nplhaib sab hauv thiab sab nrauv yog zawv zawg ntawm cov hlau tawv (xws li GCr15).
Nta: Lub siab tshaj plaws load-cov kabmob muaj peev xwm, cuam tshuam tsis kam, tab sis kev sib txhuam coefficient siab, yuav tsum tau lubrication tas li. Nws yog haum rau qis- nrawm, hnyav- lub luag haujlwm, thiab qhov hnyav hnyav.
Suffix piv txwv: GE... E (E stands for Standard Steel to Steel)
Hlau-rau-Composite (Tus kheej-Lubricating/Maintenance-Free) Hom:
Structure: Nyob rau hauv lub puab kheej kheej nto ntawm lub nplhaib hlau, ib txheej ntawm tus kheej -lubricating composite liner yog bonded los yog mechanically tsau. Lub liner feem ntau yog ua los ntawm kev sib xyaw ntawm PTFE (polytetrafluoroethylene) fibers, txhuas, thiab lwm yam.
Nta: Tsis tshua muaj coefficient ntawm kev sib txhuam, tsis tas yuav tsum tau lubrication sab nraud (kev tu-dawb), corrosion kuj. Cov kabmob muaj peev xwm thiab kub tsis kam yog qis dua li cov hom hlau. Haum rau cov xwm txheej uas tsis tuaj yeem lubrication, yuav tsum tau ntxuav, los yog kev kho mob nyuaj.
Suffix piv txwv: GE ... C (C stands rau PTFE composite liner)
Tshwj xeeb zawv zawg nto hom:
Chrome plated hom: zawv zawg nto yog plated nrog nyuaj chrome los txhim kho corrosion kuj thiab hnav tsis kam.
Stainless hlau hom: Ob qho tib si sab hauv thiab sab nrauv yog ua los ntawm cov hlau tsis muaj steel, uas yog siv rau hauv qhov chaw muaj corrosive (xws li zaub mov, tshuaj, marine).
3. Kev faib tawm los ntawm kev tshem tawm thiab preload
Txheem radial clearance: haum rau kev ua haujlwm dav dav.
Me Clearance/Precision Type: Siv nyob rau hauv cov xwm txheej uas me me clearance thiab siab dua positional raug.
Preload (kev cuam tshuam) hom: Sib dhos ua ntej tshem tawm qhov kev tshem tawm thawj zaug, muab kev nruj dua tab sis nce kev sib txhuam.
Cov yam ntxwv tseem ceeb: Aligning peev xwm thiab zawv zawg kev sib txhuam
Alignment Angle: Lub peev xwm kos npe ntawm articulated bearings. Tso cai rau lub nplhaib sab hauv kom qaij txheeb ze rau lub nplhaib sab nrauv kom them nyiaj rau kev teeb tsa tsis zoo los yog cov qauv deformation. Angular range yog qhov tseem ceeb rau kev xaiv.
Coefficient ntawm kev sib txhuam: loj sib txawv.
Hlau rau hlau: μ ≈ 0.10 - 0.20 (yuav tsum tau lubrication)
Tus kheej -lubricating PTFE hom: μ ≈ 0.03 - 0.10 (khiav qhuav)
Static vs. dynamic load peev: Qhov ntsuas qhov ntsuas ntawm cov kabmob zoo li qub ntawm cov kabmob kheej kheej (loads uas ua rau me ntsis deformation mus tas li) yog qhov taw qhia tseem ceeb, vim tias ntau daim ntawv thov raug ua rau qeeb oscillation lossis static loads. Lub peev xwm dynamic load yuav tsum xav txog lub viav vias zaus.
