Crankshaft bearing hav txwv yeem.
Cov vuas uas tau muab tso rau ntawm cov hlua ruaj ntawm lub crankshaft thiab lub tog raj kheej thaiv thiab ua lub luag haujlwm ntawm cov kabmob thiab lubrication feem ntau hu ua crankshaft bearing pads.
Crankshaft bearing feem ntau muab faib ua ob hom: bearing thiab flanging bearing. Flanged bearing plhaub tuaj yeem tsis tsuas yog txhawb nqa thiab lubricate lub crankshaft, tab sis kuj ua lub luag haujlwm ntawm axial positioning ntawm crankshaft.
nqa
Lub qhov taw qhia ntawm ob lub vuas yuav tsum fim tib sab, thiab yog hais tias qhov txuas txuas txuas cov kabmob bush tshwj xeeb ntawm ob sab, cov cim ntawm sab ntawm cov pas txuas txuas yuav tsum pom.
Cov kabmob ntev
Cov kabmob tshiab tau thauj mus rau hauv lub qhov rooj, thiab txhua qhov kawg ntawm ob daim ntawv yuav tsum yog 0.03-0.05mm siab dua li lub dav hlau bearing. Txhawm rau kom ntseeg tau tias lub plhaub bearing thiab lub rooj zaum qhov zoo sib xws, txhim kho cov cua sov dissipation nyhuv.
Cov txheej txheem empirical los xyuas qhov ntev ntawm cov kabmob bush yog: nruab cov kabmob bush, nruab cov kabmob bush npog, nruj ib kawg ntsia liaj qhov rooj raws li tus nqi torque, ntxig lub gasket ntawm 0.05mm thickness ntawm lwm qhov kawg npog thiab cov kabmob. bush seat dav hlau, thaum lub torque ntawm cov ntsia hlau kawg ntsia liaj qhov rooj mus txog 10-20N·m, yog hais tias lub gasket tsis tau muab rho tawm, nws qhia tau hais tias lub bearing. qhov ntev yog ntev dhau lawm, thiab qhov kawg tsis muaj qhov sib koom ua ke yuav tsum tau ua ntaub ntawv; Yog tias lub gasket tuaj yeem muab rho tawm, nws qhia tau tias qhov ntev ntawm cov kabmob tsim nyog; Yog hais tias lub gasket tsis screwed rau tus nqi torque, nws tsis tuaj yeem muab rho tawm, qhia tias cov kabmob bush luv dhau thiab yuav tsum tau xaiv dua.
Smooth rov qab tenon zoo
Cov kabmob rov qab yuav tsum tsis muaj qhov chaw, qhov roughness Ra yog 0.8μm, tenon tuaj yeem tiv thaiv kev sib hloov ntawm lub bushing, qhov chaw ua haujlwm, xws li tenon tsawg dhau, tuaj yeem siv los cuam tshuam qhov siab zoo tagnrho, xws li kev puas tsuaj tenon, yuav tsum tau rov ua dua. xaiv bearing bushing.
Elastic haum tsis muaj husk
Tom qab muab cov kabmob tshiab rau ntawm lub rooj zaum bearing, qhov curvature radius ntawm bearing bush yuav tsum muaj ntau tshaj qhov curvature radius ntawm lub rooj zaum qhov. Thaum lub bearing bush yog loaded rau hauv lub rooj zaum qhov, nws muaj peev xwm ua tau zoo haum nrog lub bearing lub qhov los ntawm lub caij nplooj ntoos hlav ntawm bearing bush nws tus kheej kom yooj yim cua sov dissipation. Xyuas seb lub plhaub bearing puas yog ruam, koj tuaj yeem coj mus rhaub rau sab nraum qab ntawm lub plhaub bearing los xyuas, muaj suab nrov qhia tias cov hlau thiab cov phaj hauv qab tsis muaj zog, yuav tsum tau rov xaiv dua.
Qhov sib txawv ntawm qhov sib txawv ntawm cov ntawv teev lus sib dhos yuav tsum tsim nyog
Thaum xaiv lub plhaub bearing, qhov sib txawv yuav tsum tau kuaj xyuas. Thaum lub sij hawm soj ntsuam, lub tog raj kheej ntsuas thiab lub micrometer ntsuas lub bearing bush thiab phau ntawv journal, thiab qhov txawv yog qhov haum clearance. Txoj kev tshuaj xyuas ntawm kev tshem tawm ntawm cov kabmob hav txwv yeem yog: rau cov pas nrig txuas, siv cov roj nyias nyias ntawm cov kabmob bush, nruj nreem txuas tus pas nrig ntawm cov ntaub ntawv sib txuas, tuav lub ntsia liaj qhov rooj raws li tus nqi torque, thiab tom qab ntawd viav vias Cov pas txuas txuas los ntawm tes, tuaj yeem tig 1 ~ 1/2 lem, rub tus pas txuas txuas raws li axis kev taw qhia, tsis muaj qhov sib txawv, uas yog, ua tau raws li qhov yuav tsum tau ua; Rau crankshaft shingles, siv roj rau ntawm qhov chaw ntawm txhua lub caj dab caj dab thiab cov kabmob shingles, nruab lub crankshaft thiab ceev cov bolts raws li tus nqi torque, thiab rub lub crankshaft nrog ob txhais tes, kom lub crankshaft tig 1/2 tig, thiab kev sib hloov yog lub teeb thiab sib xws yam tsis muaj kev thaiv qhov tshwm sim.
Txoj kev txhim kho kom zoo ntawm crankshaft pobzeb
Kev txhim kho kom zoo ntawm cov vuas crankshaft suav nrog cov kauj ruam tseem ceeb hauv qab no:
Txhim kho qhov sib npaug ntawm cov ncej: Txhim kho qhov sib npaug ntawm txhua sab ntawm lub crankshaft. Cov shafts sib npaug no cia siab rau cov roj txaws rau lubrication, tsis yog yuam lubrication los ntawm cov roj twj tso kua mis. Yog li ntawd, kev tswj qhov sib txawv ntawm qhov sib npaug ntawm cov ncej thiab lub plhaub bearing yog qhov tseem ceeb tshwj xeeb thiab yuav tsum khaws cia ntawm 0.15-0.20 hli.
Kev tswj qhov sib txawv thiab kev hloov kho: Yog tias qhov sib txawv tsis yooj yim rau kev tswj, koj tuaj yeem ua ntej siv lub ntsej muag los ntsuas qhov sib txawv ntawm cov kabmob bush thiab qhov sib npaug ntawm qhov sib npaug thaum cov kabmob bush tsis tau teeb tsa rau lub tog raj kheej thaiv. Qhov pom kev sib txawv yog 0.3 hli. Yog tias qhov sib txawv tsawg dua 0.3 hli, qhov loj me tuaj yeem ua tiav los ntawm kev khawb lossis ua haujlwm ntawm lub tshuab dhos kom paub meej tias cov txheej txheem cuam tshuam ntawm cov kabmob thiab cov kabmob qhov yog 0.05 hli, thiab qhov sib txawv yog li 0.18 hli tom qab cov kabmob. Bush yog tapped rau hauv lub qhov bearing.
Cov kabmob ruaj khov: Thaum txhim kho qhov sib npaug ntawm qhov sib npaug ntawm cov kabmob, 302AB kua nplaum yuav tsum tau siv rau sab nraub qaum ntawm cov kabmob hav txwv yeem kom ua kom muaj kev ruaj ntseg ntawm cov kabmob hav txwv yeem thiab tiv thaiv kom tsis txhob txav los yog xoob.
Bearing positioning thiab lubrication: txhua lub plhaub bearing muaj ib lub pob qhov chaw, uas yuav tsum tau daig rau hauv qhov chaw ntawm lub tog raj kheej thaiv. Nyob rau tib lub sijhawm, xyuas kom meej tias cov roj qhov hauv qhov kev coj tus kheej tau ua raws li cov roj hla hauv lub tog raj kheej thaiv txhawm rau tsim kom muaj lub lubrication system.
Bearing cover installation: Tom qab txhim kho thawj cov kabmob npog, tig lub crankshaft kom paub tseeb tias tsis muaj daig. Nruab ib lub hau bearing thiab nruj nws raws li qhov tshwj xeeb. Qhov no yog ua tiav rau txhua tus kabmob cap. Yog hais tias lub hau bearing yog daig, qhov teeb meem yuav yog nyob rau hauv lub bearing cap los yog nyob rau hauv cov kabmob. Tshem tawm thiab xyuas seb qhov burrs lossis tsis haum ntawm lub rooj zaum bearing.
Los ntawm ua raws li cov kauj ruam no, koj tuaj yeem xyuas kom muaj kev txhim kho kom zoo ntawm cov vuas crankshaft thiab zam kev ua haujlwm tsis zoo vim kev teeb tsa tsis raug.
