Daim ntawv thov ntawm lub tes tsho tooj liab ntawm ob lub ntsiab lus xovxwm
Ob-point xovxwm yog lub tshuab xovxwm uas siv ob txoj hlua txuas los tsav lub swb. Copper bushings thiab tooj liab bearings feem ntau yog siv rau ntawm lub crankshaft ntawm ob-point xovxwm. Copper bearings yog ntsia rau ntawm qhov ruaj khov ntawm lub crankshaft thiab lub tog raj kheej lub cev los ua lub luag haujlwm ntawm cov kabmob thiab lubrication. Crankshaft bearings (tooj liab bushings) feem ntau muab faib ua ob hom: bearings thiab flanged bearings. Flanged bearings tuaj yeem tsis tsuas yog txhawb nqa thiab lubricate lub crankshaft, tab sis kuj ua lub luag haujlwm ntawm axial positioning ntawm crankshaft.
Lub tes tsho tooj liab siv rau ntawm lub crankshaft ntawm ob lub ntsiab lus xovxwm muaj lub luag haujlwm ntawm kev txo qis hnav, tig thiab zawv zawg. Lub tes tsho tooj liab cais cov kev sib cuag ncaj qha ntawm lub crankshaft thiab cov pas nrig txuas, uas yog pab tau rau kev tu txhua hnub, kho thiab hloov, thiab muaj kev lag luam siab.
Ua ke nrog kev ua haujlwm ib puag ncig thiab cov txheej txheem ua haujlwm ntawm cov xovxwm, lub tes tsho tooj liab ntawm ob lub ntsiab lus xovxwm feem ntau yog ua los ntawm tin bronze. Tin bronze muaj cov khoom siv ntau dua, zoo dua corrosion kuj, kev sib txhuam txo thiab kev ua haujlwm zoo casting; Nws tsis tshua muaj siab rau overheating thiab roj, muaj kev ua haujlwm zoo vuam, tsis yog-ferromagnetic, thiab muaj me me shrinkage coefficient. Tin bronze muaj ntau dua corrosion kuj nyob rau hauv cov huab cua, seawater, dej tshiab thiab chav dua tooj dag.
Hauv lub teb chaws tus qauv GB/T1176-2013, cam khwb cia tin bronzes suav nrog 3-8-6-1 cam khwb cia tin bronze, 3-11-4 cam khwb cia tin bronze, 5-5-5 cam khwb cia tin bronze, 10-1 cam khwb cia tin bronze, 10-5 cam khwb cia tin bronze, 10-2 cam khwb cia tin bronze, thiab lwm yam. Cov qib sib txawv ntawm tin bronze tes tsho muaj cov khoom sib txawv. Thaum siv lawv, koj yuav tsum xaiv qib twg ntawm tin bronze siv raws li qhov xwm txheej tiag tiag. Yog tias koj xav tau kev txhawb nqa kev tsim qauv, thov hu rau peb.
