Ukugcinwa kweHydraulic Excavator Slewing Bearing

Abembi be-hydraulic basebenzisa umqolo omnye we-4-point contact ibhola yangaphakathi yeebheringi zokuxhela izinyo.Xa i-excavator isebenza, i-slewing bear ithwala imithwalo enzima efana ne-axial force, i-radial force, kunye nomzuzu wokunciphisa, kwaye ukugcinwa kwayo okufanelekileyo kubaluleke kakhulu.Ukugcinwa kweringi yokuxhela ikakhulu kubandakanya ukuthanjiswa kunye nokucocwa kwendlela yomdyarho kunye neringi yangaphakathi yegiya, ukugcinwa kwezitywina zeoli zangaphakathi nangaphandle, kunye nokugcinwa kweebholiti zokuqinisa.Ngoku ndiza kuchaza imiba esixhenxe.
w221. Ukuthanjiswa kwendlela yokubaleka
Izinto eziqengqelekayo kunye ne-raceways ye-slewing ring zonakaliswa lula kwaye zisilela, kwaye izinga lokungaphumeleli liphezulu.Ngexesha lokusetyenziswa kwe-excavator, ukongeza igrisi kumdyarho kunokunciphisa ukungqubana kunye nokunxiba phakathi kwezinto eziqengqelekayo, ugqatso, kunye ne-spacer.I-raceway cavity inendawo emxinwa kunye nokuchasana okuphezulu kokuzaliswa kwegrisi, ngoko ke imipu yegrisi ye-manual iyafuneka ukuze ifakwe ngesandla.
Xa ugcwalisa indawo yomdyarho ngegrisi, ziphephe iindlela zokuzalisa ezimbi ezifana ne "static state refueling" kunye "nendawo enye yokufaka i-refueling".Oku kungenxa yokuba ezi ndlela zokuzalisa zilambatha zikhankanywe ngasentla ziya kubangela ukuvuza kwe-oyile ngokungaphelelanga kweringi yokubulala kunye neseyile esisigxina ye-oyile yokubulala.Umonakalo ngokwesondo, okukhokelela ekulahlekeni kwegrisi, ukungena kokungcola, kunye nokuguga okukhawulezileyo kweendlela zomdyarho.Kulumkele ukudibanisa iintlobo ezahlukeneyo zegrisi ukunqanda ukusilela kwangaphambi kwexesha.
Xa kutshintshwa igrisi eyonakaliswe kakhulu kugqatso lwendandatho yokuxhela, umsesane wokuhlamba kufuneka uhambe kancinci kwaye ujikelezwe ngokufanayo ngelixa ugcwalisa, ukuze igrisi igcwaliswe ngokulinganayo kugqatso.Le nkqubo ayikwazi ukukhawuleza, kufuneka yenziwe inyathelo ngesinyathelo ukugqiba imetabolism yegrisi.
 
2. Ukugcinwa kwendawo yokuthungela izixhobo
Vula isigqubuthelo sesinyithi kwisiseko seqonga lokuxhela ukujonga ukuthambisa kunye nokunxiba kwesixhobo sokusila kunye nepini yesinciphisi semoto.I-rubber pad kufuneka ifakwe phantsi kwekhava yensimbi kwaye ifakwe kwiibholiti.Ukuba iibholiti zikhululekile okanye i-gasket yerabha iyasilela, amanzi aya kugqobhoza ukusuka kwisigqubuthelo sesinyithi ukuya kumgodi wokuthambisa (ipani yokuqokelela ioyile) yesixhobo sokujikeleza esijikelezayo, nto leyo ebangela ukusilela kwangaphambi kwexesha kwegrisi kunye nokuncipha kwesiphumo sokuthambisa, okukhokelela ekunxityweni kwegiya kunye nomhlwa.
 

Ukugcinwa kweempawu zeoli zangaphakathi nangaphandle
Ngethuba lokusetyenziswa kwe-excavator, khangela ukuba i-oyile yangaphakathi nangaphandle ye-oyile ye-slewing ring ilungile.Ukuba zonakele, kufuneka zilungiswe okanye zitshintshwe kwangethuba.Ukuba umsesane wokutywina we-slewing motor reducer yonakele, iya kubangela ukuba ioyile yegiya yangaphakathi yesinciphisi ivuze kumgodi wokuthambisa wegiya yeringi.Ngexesha lenkqubo ye-meshing ye-slewing ring ring kunye ne-pinion gear ye-slewing motor reducer, igrisi kunye ne-oyile yegiya iya kuxubana kunye neqondo lokushisa Xa linyuka, igrisi iya kuba ncinane, kwaye igrisi ebhityisiweyo iya kutyhalelwa phezulu. Umphezulu wesiphelo seringi yangaphakathi yegiya kwaye ungene kumgaqo womdyarho ngetywina langaphakathi leoli, okubangela ukuvuza kwe-oyile kunye nokuthontsiza ukusuka kwisitywina se-oyile sangaphandle, okukhokelela kwizinto eziqengqelekayo, iindlela zomdyarho nangaphandle Isitywina seoli sikhawulezisa umonakalo.
Abanye abaqhubi bacinga ukuba umjikelo we-lubrication we-slewing ring ufana ne-boom kunye nentonga, kwaye kuyimfuneko yokongeza igrisi yonke imihla.Enyanisweni, kuphosakele ukwenjenjalo.Oku kungenxa yokuba ukugcwaliswa kwegrisi rhoqo kuya kubangela igrisi eninzi kakhulu kumdyarho, nto leyo eya kubangela ukuphuphuma kwegrisi kumatywina e-oyile angaphakathi nangaphandle.Ngexesha elifanayo, ukungcola kuya kungena kwi-raceway yokubulala, ukukhawuleza ukunxiba kwezinto ezijikelezayo kunye nomzila.
w234. Ukugcinwa kweebholithi zokuqinisa
Ukuba i-10% yeebholiti zendandatho yokubethela zikhululekile, ezinye iibholiti ziya kufumana amandla amakhulu phantsi kwesenzo sobunzima kunye noxinzelelo lwemithwalo.Iibholiti ezikhululekileyo ziya kuvelisa imithwalo yempembelelo ye-axial, ekhokelela ekukhululekeni okwandileyo kunye neebholiti ezikhululekileyo ngakumbi, ezikhokelela ekuqhekekeni kwebholithi, kunye neengozi nokufa.Ngoko ke, emva kwe-100h yokuqala kunye ne-504h yeringi yokubulala, i-torque yokuqinisa i-bolt kufuneka ihlolwe.Emva koko, i-torque yokuqinisa kwangaphambili kufuneka ihlolwe rhoqo nge-1000h yomsebenzi ukuqinisekisa ukuba iibholithi zinamandla okwaneleyo okuqinisa kwangaphambili.
Emva kokuba i-bolt isetyenziswe ngokuphindaphindiweyo, amandla ayo okuqina aya kuncitshiswa.Nangona i-torque ngexesha lokufakela kwakhona idibana nexabiso elichaziweyo, amandla okuqinisa kwangaphambili kwebholithi emva kokuqiniswa kuya kuncitshiswa.Ngoko ke, xa uphinda uqinisa iibholithi, i-torque kufuneka ibe yi-30-50 N·m enkulu kunexabiso elichaziweyo.Ukulandelelanisa ukunyanzeliswa kweebholithi zokubethelwa kufuneka ziqiniswe ngokuphindaphindiweyo kwi-180 ° ye-symmetrical direction.Xa uqiniswa ixesha lokugqibela, zonke iibholithi kufuneka zibe namandla afanayo okuqinisa.
 
5. Ukulungelelaniswa kokususwa kwezixhobo
Xa uhlengahlengisa isikhewu segiya, nikela ingqalelo ekujongeni ukuba iibholithi zokudityaniswa kwesinciphisi semoto kunye neqonga lokurhabula zikhululekile, ukuze uthintele umsantsa we-gear meshing ukuba ube mkhulu kakhulu okanye umncinci kakhulu.Oku kungenxa yokuba ukuba ukucocwa kukhulu kakhulu, kuya kubangela impembelelo enkulu kwiigiya xa i-excavator iqala kwaye imisa, kwaye ixhomekeke kwingxolo engaqhelekanga;ukuba ucoceko luncinci kakhulu, luya kubangela umsesane wokuxhela kunye nepinion yesinciphisi semotor ukuba ibe jam, okanye Ibangele amazinyo aphukileyo.
Xa uhlengahlengisa, nikela ingqalelo ukuba iphini lokumisa phakathi kwe-motor swing kunye neqonga le-swing likhululekile.Iphini yokubeka kunye nomngxuma wesikhonkwane zezomfaneleko wophazamiseko.Iphini yokubeka ayidlali kuphela indima ekumiseni, kodwa ikwanyusa amandla okuqinisa ibholithi yesinciphisi semoto ejikelezayo kwaye inciphisa ukubanakho ukukhulula isinciphisi semoto ejikelezayo.
w24Ulondolozo oluvaliweyo
Nje ukuba iphini lokumisa lebloko esisigxina likhululekile, liya kubangela ukugxothwa kwebhloke, kubangele umzila womdyarho utshintshe kwindawo evalekileyo.Xa i-elementi eqengqelekayo ishukuma, iya kungqubana nokuvaleka kwaye yenze ingxolo engaqhelekanga.Xa usebenzisa i-excavator, umqhubi kufuneka anikele ingqalelo ekucoceni udaka olugqunywe yi-blockage kwaye ajonge ukuba i-blockage iyasuswa.
w25Gwema ukuhlamba i-slewing bear ngamanzi
Akuvumelekanga ukugungxula ibhere yokuxhela ngamanzi ukunqanda amanzi akhuhlayo, ukungcola, kunye nothuli ekungeneni kwiringi yokubulala, kubangele umhlwa kunye nomhlwa wendlela yomdyarho, okukhokelela ekuxutyweni kwegrisi, ukutshabalalisa imeko yokuthambisa, kunye nokuwohloka. yegrisi;kunqanda nasiphi na isinyibilikisi esidibana ne-slewing ring oil seal.
 
Ngamafutshane, emva kokuba i-excavator isetyenziswe ixesha elithile, ukubethelwa kwayo kuhambelana nokungasebenzi kakuhle njengengxolo kunye neempembelelo.Umsebenzisi kufuneka anikele ingqalelo ekujongeni kwaye ajonge ngexesha lokuphelisa ukungasebenzi kakuhle.Kuphela ukugcinwa okuchanekileyo kunye nokufanelekileyo kwendandatho yokubulala kunokuqinisekisa ukusebenza kwayo ngokuqhelekileyo, ukunika umdlalo opheleleyo ekusebenzeni kwayo, kunye nokwandisa ubomi bayo benkonzo.
