Bearing kev lag luam kev loj hlob

Tuam Tshoj yog ib lub teb chaws uas tsim dov bearings ua ntej nyob rau hauv lub ntiaj teb no, thiab cov qauv ntawm qag bearings tau sau tseg nyob rau hauv ancient Suav phau ntawv. Los ntawm qhov kev xav ntawm archaeological relics thiab cov ntaub ntawv, Tuam Tshoj tus hiob bearing nrog cov qauv ntawm niaj hnub dov bearing qauv tshwm sim nyob rau hauv 221-207 BC (Qin Dynasty) nyob rau hauv Xuejiaya Zos, Yongji County, Shanxi xeev. Tom qab kev tsim ntawm Tuam Tshoj Tshiab, tshwj xeeb tshaj yog txij li xyoo 1970, nyob rau hauv lub zog muaj zog ntawm kev hloov kho thiab qhib, kev lag luam bearing tau nkag mus rau lub sijhawm tshiab ntawm kev loj hlob sai.

Thaum kawg ntawm lub xyoo pua 17th, cov British C. Vallow tau tsim thiab tsim cov pob bearings, thiab muab lawv tso rau ntawm cov tsheb thauj khoom xa mus rau kev sim thiab British P. Tsim nyog tau txais cov kabmob pob. Thaum kawg ntawm lub xyoo pua 18th, HR Hertz ntawm lub teb chaws Yelemees tau luam tawm ib daim ntawv ntawm kev sib cuag kev ntxhov siab ntawm pob bearings. Raws li lub hauv paus ntawm Hertz qhov kev ua tiav, R. Stribeck ntawm lub teb chaws Yelemees, A. Palmgren ntawm Sweden thiab lwm tus tau ua tiav ntau qhov kev sim, thiab tau pab txhawb rau kev tsim qauv kev xav ntawm dov bearings thiab kev suav ntawm lub neej qaug zog. Tom qab ntawd, NP Petrov ntawm Russia tau siv Newton txoj cai lij choj ntawm viscosity los xam cov kabmob sib txhuam.

O. Reynolds ntawm lub tebchaws United Kingdom tau ua kev tshawb fawb txog lej ntawm Thor qhov kev tshawb pom thiab muab tau los ntawm Reynolds equation, uas tau tsim lub hauv paus ntawm txoj kev xav ntawm hydrodynamic lubrication. Daim ntawv thaum ntxov ntawm cov kab ntawv tawm suab yog ib kab ntawm cov ncej ntoo muab tso rau hauv qab daim phiaj. Cov txheej txheem yuav rov qab mus rau kev tsim kho ntawm Great Pyramid ntawm Giza, txawm hais tias tsis muaj pov thawj tseeb ntawm qhov no. Niaj hnub nimno linear motion bearings siv tib txoj hauv kev ua haujlwm, tab sis qee zaum siv lub pob es tsis txhob siv cov menyuam. Qhov ntxov tshaj plaws zawv zawg thiab dov lub cev bearings yog ua los ntawm ntoo. Ceramics, sapphire, lossis iav kuj tseem siv, thiab hlau, tooj liab, lwm yam hlau, thiab yas (xws li nylon, bakelite, Teflon, thiab UHMWPE) yog txhua yam siv.

Rotating bearings yog xav tau nyob rau hauv ntau daim ntawv thov, los ntawm hnyav-lub luag hauj lwm log axles thiab tshuab cuab tam spindles rau precision saib qhov chaw. Qhov yooj yim tshaj plaws ntawm rotating bearing yog bushing bearing, uas tsuas yog ib tug bushing sandwiched ntawm lub log thiab lub qag. Qhov kev tsim no tom qab hloov los ntawm dov bearings, uas hloov cov thawj bushing nrog ib tug xov tooj ntawm cylindrical rollers, txhua yam uas ua zoo li ib tug nyias muaj nyias lub log. Thawj qhov kev ua tau zoo nrog lub tawb tau tsim los ntawm watchmaker John Harrison hauv xyoo 1760 rau kev tsim H3 chronograph.

Ib qho piv txwv thaum ntxov ntawm lub pob kabmob tau pom nyob rau ntawm lub nkoj Roman thaum ub nyob hauv Lake Nami, Ltalis. Qhov no ntoo pob bearing yog siv los txhawb lub rotating rooj saum. Lub nkoj tau tsim nyob rau hauv 40 BC. Leonardo Da Vinci tau hais tias tau piav qhia txog hom pob bearing nyob ib ncig ntawm 1500. Ntawm ntau yam tsis paub qab hau ntawm pob bearings, ib qho tseem ceeb heev yog tias yuav muaj kev sib tsoo ntawm cov pob, ua rau muaj kev sib txhuam ntxiv. Tab sis qhov no tuaj yeem tiv thaiv tau los ntawm kev muab lub pob rau hauv lub tawb.

Nyob rau hauv lub xyoo pua 17th, Galileo Galilea tau piav qhia ntxov tshaj plaws ntawm "taw pob", lossis "cage pob" pob bearings. Txawm li cas los xij, nyob rau lub sijhawm ntev heev, kev teeb tsa ntawm cov bearings ntawm lub tshuab tsis tau pom dua. Thawj patent rau pob ditch tau tso cai los ntawm Philip Vaughan ntawm Carmarthen hauv 1794.

Nyob rau hauv 1883, Friedrich Fischer tau npaj lub tswv yim ntawm kev siv lub tshuab tsim nyog los zom cov pob steel ntawm tib qhov loj thiab nrog qhov tseeb roundness. Qhov no nteg lub hauv paus rau lub creation ntawm ib tug ywj siab bearing kev lag luam. "Fischers Automatische Guß Cov npe sau npe stahlkugelfabrik lossis Fischer Aktien-Gesellschaft tau dhau los ua lub cim lag luam, sau npe rau 29 Lub Xya Hli 1905.

Xyoo 1962, FAG lub cim lag luam raug hloov kho thiab tseem siv tau niaj hnub no, dhau los ua ib feem tseem ceeb ntawm lub tuam txhab xyoo 1979.

Nyob rau hauv 1895, Henry Timken tau tsim thawj tapered menyuam bearing, uas nws patented peb xyoos tom qab ntawd thiab nrhiav Timken.

Nyob rau hauv 1907, Sven Winqvist ntawm SKF Bearing Hoobkas tsim thawj tus kheej-aligning pob bearings.

Cov kabmob yog ib qho tseem ceeb ntawm txhua yam ntawm cov cuab yeej siv tshuab, thiab nws qhov tseeb, kev ua tau zoo, lub neej thiab kev ntseeg tau ua lub luag haujlwm txiav txim siab rau qhov tseeb, kev ua tau zoo, lub neej thiab kev ntseeg siab ntawm tus tswv tsev. Hauv cov khoom siv tshuab, bearings yog cov khoom siv high-precision, tsis tsuas yog xav tau kev txhawb nqa ntawm lej, physics thiab ntau lwm yam kev qhuab qhia, tab sis kuj xav tau cov khoom siv science, kev kho cua sov thev naus laus zis, precision machining thiab ntsuas thev naus laus zis, kev tswj cov lej thiab cov lej zoo. thiab haib computer technology thiab ntau lwm yam kev qhuab qhia los pab, yog li bearing yog ib tug neeg sawv cev ntawm lub teb chaws scientific thiab technology zog ntawm cov khoom.

Nyob rau hauv xyoo tas los no, lub ntiaj teb nto moo lag luam tau nkag mus rau hauv Suav lag luam bearing thiab tsim cov hauv paus tsim khoom, xws li Sweden SKF Group, Lub teb chaws Yelemees Schaeffler Group, United States Timken Company, Nyiv NSK Tuam Txhab, NTN Company thiab lwm yam. Cov tuam txhab no tsis yog kev ua haujlwm thoob ntiaj teb nkaus xwb, tab sis kuj tseem tsim khoom thoob ntiaj teb, lawv vam khom rau qhov zoo ntawm cov khoom lag luam, cov cuab yeej siv, thev naus laus zis, peev thiab ntau lawm, thiab cov tuam txhab lag luam hauv tsev tau pib muaj kev sib tw hnyav. Nrog rau txoj kev loj hlob ntawm Tuam Tshoj tus kabmob kev lag luam, cov khoom tsim ntawm lub tes tsho ncej yuav hloov, qhov feem ntawm nws cov high-end khoom nyob rau hauv cov khoom yuav nce, chav tsev nqi ntawm kev muag khoom kuj nce, Tuam Tshoj tus bearing ntau lawm yuav tsum tau los ua tus ntiaj teb coob bearing ntau lawm thiab muag puag.

Nrog rau kev sib tw tsis tu ncua ntawm kev sib tw hauv kev lag luam bearing, mergers thiab acquisitions thiab peev kev lag luam ntawm loj bearing manufacturing tuam txhab tau dhau los ua ntau zaus, thiab domestic zoo heev bearing manufacturing tuam txhab tau them ntau thiab ntau xim rau kev tshawb fawb ntawm kev lag luam kev lag luam, tshwj xeeb tshaj yog cov kev kawm tob txog kev tsim kho ib puag ncig kev lag luam thiab cov neeg yuav khoom. Vim li no, coob tus ntawm domestic zoo heev bearing manufacturing hom tau nce sai heev thiab maj mam dhau los ua tus thawj coj hauv kev lag luam bearing!
