Lub slewing bearing mechanism ntawm ntauwd crane yog tsim los ntawm slewing bearing, slewing tsav thiab sab sauv thiab qis.Ntauwd crane slewing bearing sib dhos nyob rau hauv cov txheej txheem ua haujlwm feem ntau yuav tsis ua haujlwm zoo thiab lub suab nrov tshaj tus qauv ( suab nrov txawv txav) txhaum.Tus sau ua ke nrog nws tus kheej kev paub ua haujlwm los ntawm covslewing bearing, slewing mechanism thiab slewing bearing faults feem, nyob rau hauv cov txheej txheem ntawm kev tsim khoom, kev sib dhos kuaj, kev tu cov cuab yeej thiab lwm yam ntawm lawv tus kheej lub tswv yim thiab cov tswv yim.

Ntauwd crane slewing nplhaib tsis ua hauj lwm tiv thaiv kev ntsuas thiab kev saib xyuas

1.slewing nplhaib iav yuav tsum

Kev sib cuag thiab khoov lub zog ntawm lub zog hauv qab qhov kawg thiab qaug zog loads tau suav thiab txheeb xyuas raws li ISO6336-1: 2006, ISO6336-2: 2006 thiab ISO6336-3: 2006 raws li.Sf yog 1.48 thiab cov iav mesh tshem tawm yog hloov kho rau qhov siab tshaj plaws ntawm radial khiav tawm ntawm slewing bearing iav suab lub voj voog.Qhov tsawg kawg nkaus tshem tawm cov hniav feem ntau yog 0.03 txog 0.04x modulus, thiab cov iav mesh tshem tawm ntawm cov pinion iav ntawm tag nrho cov ncig yuav tsum tau rov kuaj xyuas tom qab zaum kawg fastening ntawm slewing bearing.

2. Slewing bearing nrog lubrication
Nyob rau hauv txhua hnub siv yuav tsum tau raws sij hawm, raws sij hawm, raws li cov lus qhia phau ntawv qhia rau txhua yam raws li lub lubricant, lubrication, lubrication voj voog cov kev cai rau lubrication.Sib raugpob slewing nplhaibFeem ntau rov qab ua dua txhua 100 teev ntawm kev ua haujlwm, cov menyuam slewing nplhaib yog rov ua dua txhua 50 teev, rau plua plav, av noo, kub sib txawv ntawm qhov chaw ua haujlwm tshwj xeeb yuav tsum luv lub voj voog lubrication.Txhua lubrication yuav tsum tau sau cov raceway kom txog thaum lub lubricant seeps tawm, sau thaum maj mam tig lub slewing bearing kom cov roj sib npaug.Los ntawm kev sau cov roj lubricating, nws tuaj yeem txo qhov kev sib txhuam ntawm cov iav khub, ua kom qis qis ntawm lub nplhaib iav, tsim cov roj zaj duab xis kuj tuaj yeem ua lub luag haujlwm ntawm kev poob siab absorbing nplhaib, tshem tawm ib feem ntawm lub zog vibration generated. hauv kev ua haujlwm.Tsis tas li ntawd, lub lubricating roj zaj duab xis kuj tuaj yeem ua tau zoo lubricating ntxuav qhov kev sib txhuam ntawm qhov chaw, tiv thaiv corrosion, thiab tshem tawm cov kev cuam tshuam ntawm cov khoom hlau ntawm kev sib txhuam.Txhawm rau txo cov suab nrov ntawm kev sib txhuam hauv kev ua haujlwm thiab ua kom lub neej ua haujlwm ntawm slewing bearing.

3. Ceev ceev bolts
Kev sib txuas bolts ntawm slewing bearing thiab sab sauv thiab qis slewing bearing yog raug rau axial pulsating load ntxiv rau cov preload, uas yuav ua rau cov bolts yuav ncab los yog cov pob qij txha deformed, ua rau cov bolts loosen.Bolt kev sib koom ua ke loosening preload tsis ncav cuag qhov xav tau axial clearance nce, dov lub cev los ntawm kev sib hloov torque loj, kev sib tw ntug los ntawm kev sib cuag loj heev, ua rau kev sib tw ntug kev puas tsuaj.Ib lub nroog muaj QTZ 25 ntauwd crane sab saum toj qauv kev sib tsoo, qhov ncaj qha ua rau cov kabmob slewing thiab cov kabmob slewing sab saud hauv cov haujlwm uas tsis tau teev tseg, ua rau txhua pawg ntsia liaj qhov rooj nyob rau hauv lem, txuas ntxiv mus rau ntau tshaj nws nqa. muaj peev xwm ntawm pawg bolt.Qhov no ua rau cov qauv sab saud ntawm tus pej thuam (nrog nws cov kabmob slewing) rhuav tshem ntawm cov qauv ntauwd thiab toppling over.The slewing bearing bolt tightening thiab nws lub zog xaiv qib tseem ceeb heev.Yog li ntawd, slewing bearing bolt fastening thiab nws lub zog qib xaiv yog qhov tseem ceeb heev.

4. Kev teeb tsa thiab kev ua haujlwm

Kev txhim kho lub nplhaib slewing yuav tsum tau xaiv nrog lub zog siab bolts, bolts thiab ceev yuav tsum ua raws li GB3098.1 thiab GB3098.2 tus qauv yuav tsum txwv tsis pub siv lub caij nplooj ntoos hlav ntxhua khaub ncaws.Ua ntej zawm lub mounting bolts, sizing iav meshing hloov kho (sab clearance) yuav tsum tau ua kom paub tseeb tias cov slewing bearing thiab pinion mesh kom tau raws li qhov yuav tsum tau muaj.Tighten lub bolts yuav tsum nyob ntawm 180 °, lub dav hlau installation yuav tsum huv si thiab tiaj tus, tsis muaj burrs, hlau shavings thiab lwm yam khib nyiab, lub dav hlau yuav tsum tau raws li qhov yuav tsum tau.

Ntauwd crane slewing nplhaib nyob rau hauv kev ua haujlwm feem ntau kuj tseem muaj cov hniav tsis ua haujlwm, yog li tus pej thuam crane hauv kev ua haujlwm yuav tsum tau coj mus rau hauv tus account cua cuam tshuam rau lub nplhaib slewing, yog tias ntau tshaj qhov kev ua haujlwm cua lossis nres ua haujlwm tom qab lub crane boom tsis tuaj yeem tig. ywj pheej nrog cua, qhov no yuav ua rau lub iav puas thiab lub slewing bearing kev koom tes los yog slewing nplhaib, kev huam yuaj loj yuav tshwm sim.Yog li ntauwd crane nyob rau hauv kev teeb tsa thiab kev ua haujlwm yuav tsum ua kom muaj kev soj ntsuam kom ntxaws.
