Cov kabmob hu ua "kev sib koom ua ke ntawm kev lag luam" thiab tau siv dav hauv ntau yam kev lag luam hauv tebchaws thiab kev tsim kho kev tiv thaiv hauv tebchaws. Hnub no kuv yuav coj koj mus kawm txog ib qho kev tivthaiv hauv tsheb-universal sib koom tes bearings. Lub npe hu ua universal joint bearing yog hais txog cov qauv siv tshuab uas siv cov kev sib txuas sib txuas kom paub txog kev xa hluav taws xob ntawm cov axes sib txawv. Kev sib koom ua ke ntawm kev sib koom ua ke thoob ntiaj teb thiab cov ncej tsav yog hu ua universal sib koom ua ke sib kis.
Kev faib tawm
Universal sib koom tes bearings feem ntau muab faib ua qhov nrawm nrawm universal thrust pob bearing pob qij txha, tas li tshaj tawm universal pob qij txha, pob tawb universal pob qij txha, peb tus pin universal pob qij txha, ob lub Hoobkas pob qij txha, thiab lwm yam. qhov tsis zoo, thiab kuj tseem siv tau rau ntau qhov chaw. Piv txwv li, lub pob tawb hom universal sib koom ua ke, vim tias qhov siab tshaj plaws kev sib tshuam ntawm ob lub axes yog 42 & am hom. Txawm hais tias qhov kev taw qhia kis tau tus mob thaum lub sijhawm ua haujlwm, rau lub pob steel yuav tag nrho cov xaim hluav taws xob. Nws muaj cov yam ntxwv ntawm cov qauv compact, muaj zog load-bearing muaj peev xwm, thiab yooj yim disassembly thiab sib dhos. Nws tau dhau los ua ib qho kev siv kabmob feem ntau hauv cov tsheb tam sim no.
Lub universal sib koom tes bearing ua kom cov kev ua haujlwm yooj yim ntawm lub tsheb. Nyob rau pem hauv ntej-engine rear-wheel tsav tsheb, universal sib koom tes kis tau tus mob ntaus ntawv yog ntsia nruab nrab ntawm lub kis tau tus mob tso zis ncej thiab lub transaxle lub ntsiab reducer input ncej. Ntawm lub cav pem hauv ntej, lub log tsav tsheb, lub log tsav tau raug tshem tawm, yog li kev sib koom ua ke thoob ntiaj teb yog nruab nrab ntawm lub hauv ntej qag ib nrab-ncej thiab lub log, uas yog lub luag haujlwm rau kev tsav tsheb thiab lub kauj.
Tej kev txhaum thiab kev daws teeb meem
Peb paub tias bearings xav tau kev saib xyuas tsis tu ncua txhawm rau tshem tawm qhov yuam kev. Cov kev ua txhaum ntawm universal sib koom tes bearings feem ntau yog hnav ntawm phau ntawv journal thiab bearing thiab dabtsi yog khoov deformation ntawm txhua phau ntawv journal, ua rau cov kab nruab nrab ntawm tus ntoo khaub lig shafts tsis nyob rau hauv tib lub dav hlau, los yog ob tug nyob ib sab shafts. Lub axis centerline tsis yog ntsug. Vim yog qhov sib txawv ntawm qhov sib txawv ntawm cov ntawv xov xwm universal sib koom ua ke thiab cov kabmob, tus ncej ntoo khaub lig shakes thaum lub sijhawm ua haujlwm, ua rau cov kab nruab nrab ntawm cov ncej txuas mus rau qhov sib txawv ntawm nws txoj kab kev sib hloov, ua rau cov ncej xa mus rau vibrate thiab ua suab nrov txawv txav. thaum ua haujlwm.
Kev hnav ntawm universal joint cross ncej journal thiab bearing yuav tsum tsis txhob ntau tshaj {{0}}}02~0.13mm raws li cov kev siv, thiab feem ntau yog tswj nyob ib ncig ntawm 0.01mm ib. Yog tias nws siab tshaj 0.13mm, lub xaim xaim yuav vibrate thiab ua suab nrov. Hnav feem ntau yog tshwm sim los ntawm tsis muaj lubrication, yog li kev saib xyuas tsis tu ncua yog qhov tseem ceeb heev. Roj yuav tsum tau ntxiv ntau zaus thaum lub sij hawm tu txhua hnub kom tsis txhob hnav ntawm cov ntawv xov xwm cross ncej thiab bearings vim tsis muaj roj.
Kev ceev faj thaum siv
Thaum kawg, cia peb saib cov kev ceev faj thaum siv universal joint bearings. Thaum lub sij hawm disassembly, kev thauj mus los, thiab kev cia khoom, kev sib tsoo thiab kev sib tsoo yuav tsum raug zam; Lub sealing tej yam kev mob ntawm intermediate txhawb bearings, cross ncej bearings, thiab zawv zawg splines yuav tsum tau xyuas ntau zaus. Hloov cov roj ntsaws ruaj ruaj tam sim. Nquag txhaj roj. Nyob rau hauv thiaj li rau txhua bearing ntawm lub universal sib koom ua ke kom tag nrho lubricated, cov roj lubricating yuav tsum tau nyem tawm ntawm cov roj foob ntawm txhua tus kabmob. Nquag xyuas cov radial thiab axial clearance ntawm qhov nruab nrab kev txhawb nqa bearing, axial clearance ntawm tus ntoo khaub lig ncej, qhov sib txuam clearance ntawm tus ntoo khaub lig ncej thiab cov kabmob, cov kabmob thiab universal sib koom diav rawg qhov, lub circumferential clearance ntawm zawv zawg spline khub, thiab lwm yam, kom ncua nws lub neej kev pab cuam. Qhov tseeb, kev siv cov kabmob yuav tsum tau ua raws li cov lus qhia ua haujlwm, kev saib xyuas tsis tu ncua, thiab kho raws sijhawm lossis hloov pauv yog tias pom muaj kev puas tsuaj me me, txhawm rau ua kom cov kabmob ua haujlwm tau zoo tshaj plaws.
