Ukugcinwa kwe-Hydraulic Excavator Slewing Bearing

Ama-excavators asebenzisa i-hydraulic ngokuvamile asebenzisa ama-bearings angaphakathi okujula ezinyo anomugqa owodwa enamaphuzu angu-4.Uma i-excavator isebenza, i-slewing bear ithwala imithwalo eyinkimbinkimbi efana ne-axial force, amandla e-radial, kanye nomzuzu wokunciphisa, futhi ukugcinwa kwayo okunengqondo kubaluleke kakhulu.Ukugcinwa kweringi yokuhlinza ikakhulukazi kuhlanganisa ukugcotshwa nokuhlanza umzila womjaho kanye neringi yegiya langaphakathi, ukugcinwa kwezigxivizo zikawoyela zangaphakathi nezingaphandle, nokugcinwa kwamabhawudi okuqina.Manje ngizonaba ngezici eziyisikhombisa.
w221. Ukugcotshwa komzila womjaho
Izakhi eziginqikayo nezindlela zomjaho zendandatho yokugeba zilimala kalula futhi ziyehluleka, futhi izinga lokuhluleka liphezulu uma kuqhathaniswa.Ngesikhathi sokusebenzisa i-excavator, ukwengeza amafutha kumzila womjaho kunganciphisa ukungqubuzana nokuguga phakathi kwezinto ezigoqayo, umgwaqo womjaho, kanye nesikhala.I-raceway cavity inesikhala esincane kanye nokumelana okuphezulu nokugcwalisa amafutha, ngakho-ke izibhamu ze-grease manual ziyadingeka ukuze kugcwaliswe ngesandla.
Uma ugcwalisa imbobo yomjaho ngamafutha, gwema izindlela zokugcwalisa ezimbi njengokuthi "static state refueling" kanye "nokugcwalisa iphuzu elilodwa".Lokhu kungenxa yokuthi lezi zindlela zokugcwalisa ezimbi ezibalwe ngenhla zizobangela ukuvuza kwengxenye kawoyela wendandatho yokubulala ngisho nezigxivizo zamafutha ezicijile ezingapheli.Ukulimala kocansi, okuholela ekulahlekelweni kwamafutha, ukungena kokungcola, nokushesha ukuguga kwemigwaqo yomjaho.Qaphela ukuthi ungahlanganisi izinhlobo ezahlukene zamafutha ukuze ugweme ukwehluleka ngaphambi kwesikhathi.
Uma ushintsha igrisi ewohloke kakhulu emgwaqeni wendandatho yokubulala, indandatho yokubulala kufanele ibe kancane futhi ijikelezwe ngokufanayo ngenkathi igcwalisa, ukuze amafutha agcwaliswe ngokulinganayo emjahweni.Le nqubo ayikwazi ukushesha, idinga ukwenziwa isinyathelo ngesinyathelo ukuqedela i-metabolism yamafutha.
 
2. Ukunakekelwa kwendawo ye-gear meshing
Vula isembozo sensimbi esisekelweni seplathifomu yokuhlinza ukuze ubuke ukugcotshwa nokuguga kwegiya lendandatho yokuhlaba kanye nephinikhodi yesinciphisi senjini yokuhlaba.I-rubber pad kufanele ifakwe ngaphansi kwesembozo sensimbi futhi iboshwe ngamabholithi.Uma amabhawodi exega noma i-gasket yerabha ihluleka, amanzi azogeleza asuke esembozweni sensimbi aye endaweni yokuthambisa (ipani lokuqoqa uwoyela) legiya lendandatho elizungezayo, okubangele ukwehluleka kwamafutha ngaphambi kwesikhathi kanye nomphumela oncishisiwe wokugcoba, okuholela ekwenyukeni kokugqoka kwegiya nokugqwala.
 

Ukugcinwa kwezimpawu zamafutha zangaphakathi nangaphandle
Ngesikhathi sokusebenzisa i-excavator, hlola ukuthi ingabe izimpawu zikawoyela zangaphakathi nezangaphandle zendandatho yokubulala ziqinile.Uma zonakalisiwe, kufanele zilungiswe noma zishintshwe ngesikhathi.Uma indandatho yokuvala yesinciphisi semoto yonakele, izobangela uwoyela wegiya langaphakathi lesinciphisi ukuthi avuze endaweni yokuthambisa yegiya leringi.Ngesikhathi senqubo yokuhlanganisa igiya lendandatho yokujula kanye negiya lephinikhodi le-slewing motor reducer, amafutha kanye nowoyela wegiya azohlangana kanye nezinga lokushisa Lapho likhuphuka, amafutha ayoba mncane, futhi amafutha amancane azophushwa aye phezulu. ekugcineni kwendandatho yegiya langaphakathi futhi ingene emgwaqeni womjaho ngokusebenzisa uphawu lwamafutha lwangaphakathi, okubangela ukuvuza kukawoyela nokuconsa ku-oyili yangaphandle, okuholela ekugoqekeni, emigwaqweni yomjaho nangaphandle Isici samafutha sisheshisa umonakalo.
Abanye o-opharetha bacabanga ukuthi umjikelezo wokugcoba wendandatho yokubulala ufana nowe-boom kanye nenduku, futhi kuyadingeka ukwengeza amafutha nsuku zonke.Eqinisweni, akulungile ukwenza kanjalo.Lokhu kungenxa yokuthi ukugcwaliswa kabusha kwamafutha njalo kuzodala amafutha amaningi emjahweni, okuzokwenza ukuthi amafutha agcwale ezimpahleni zikawoyela zangaphakathi nangaphandle.Ngesikhathi esifanayo, ukungcola kuzongena emgwaqeni we-slewing ring, ukusheshisa ukugqokwa kwezinto ezigoqayo kanye nomjaho.
w234. Ukugcinwa kwama-fastening bolt
Uma u-10% wamabhawodi wendandatho yokushutheka exega, amanye amabhawodi azothola amandla amakhulu ngaphansi kwesenzo semithwalo eqinile necindezelayo.Amabhawodi axegayo azokhiqiza imithwalo ye-axial yomthelela, okuholela ekwandeni kokuxega namabhawodi axegayo, okuholela ekuqhekekeni kwebhawodi, ngisho nokuphahlazeka nokufa.Ngakho-ke, ngemva kwehora lokuqala elingu-100 no-504h lendandatho yokugeba, itorque yokuqinisa ibhawodi kufanele ihlolwe.Ngemva kwalokho, i-torque yokuqinisa ngaphambi kwesikhathi kufanele ihlolwe njalo ngemva kwehora elingu-1000 ukuze kuqinisekiswe ukuthi amabhawodi anamandla anele okuqinisa ngaphambilini.
Ngemva kokuba ibhowudi isetshenziswe ngokuphindaphindiwe, amandla ayo okuqina azoncishiswa.Nakuba i-torque phakathi nokufakwa kabusha ihlangabezana nevelu elishiwo, amandla okuqinisa ngaphambili ebhawodi ngemva kokuqiniswa nawo azoncishiswa.Ngakho-ke, lapho uqinisa kabusha amabhawodi, itorque kufanele ibe ngu-30-50 N·m enkulu kunenani elishiwo.Ukulandelana kokuqinisa amabhawudi athwele ama-slewing kufanele kuqiniswe izikhathi eziningi endaweni eyi-symmetrical engu-180°.Lapho uqinisa okokugcina, wonke amabhawodi kufanele abe namandla afanayo okuqinisa ngaphambili.
 
5. Ukulungiswa kokukhishwa kwegiya
Lapho ulungisa igebe legiya, qaphela ukuthi ingabe amabhawodi axhumayo esinciphisi senjini eshushayo akhululekile, ukuze ugweme igebe le-meshing legiya ukuthi libe likhulu kakhulu noma libe lincane kakhulu.Lokhu kungenxa yokuthi uma imvume inkulu kakhulu, izodala umthelela omkhulu kumagiya lapho i-excavator iqala futhi ima, futhi ijwayele ukuba nomsindo ongajwayelekile;uma imvume incane kakhulu, izobangela indandatho yokubulala kanye nephinikhodi yokunciphisa i-motor ukuthi ibe jamu, noma Ibangele amazinyo aphukile.
Lapho ulungisa, naka ukuthi iphinikhodi yokumisa phakathi kwenjini yokushwiba kanye nesiteji sokushwiba ikhululekile yini.Iphinikhodi yokuma kanye nembobo yokukhonjwa kungokwesilinganiso sokuphazamiseka.Iphinikhodi yokumisa ayidlali indima nje kuphela ekumiseni, kodwa futhi inyusa amandla okuqinisa ibhawodi esinciphisi se-rotary motor futhi inciphisa amathuba okuxega kwesinciphisi se-rotary motor.
w24Ukulungiswa okuvalekile
Uma iphinikhodi yokumisa yokuvinjwa okungaguquki isixegisiwe, izodala ukugudluka kokuvinjwa, okubangele ukuthi umzila womjaho ushintshe engxenyeni yokuvinjwa.Lapho i-elementi eginqikayo ihamba, izoshayisana nokuvimbekile futhi yenze umsindo ongajwayelekile.Uma usebenzisa i-excavator, opharetha kufanele anake ukuhlanza udaka oluvalwe ukuvinjelwa futhi abheke ukuthi ukuvinjelwa kuyasuswa yini.
w25Gwema ukugeza i-slewing bear ngamanzi
Akuvunyelwe ukugeza i-slewing bear ngamanzi ukuze kugwenywe amanzi akhukhulayo, ukungcola, nothuli ekungeneni emgwaqeni womjaho, okubangela ukugqwala nokugqwala komgwaqo, okuholela ekuhlanjululweni kwamafutha, kucekele phansi isimo sokuthambisa, nokuwohloka. kwamafutha;gwema noma iyiphi i-solvent ethintana ne-slewing ring oil seal, Ukuze ingabangeli ukugqwala kwe-oil seal.
 
Ngamafuphi, ngemva kokuba i-excavator isetshenziswe isikhathi esithile, ukuthwala kwayo kujwayele ukungasebenzi kahle okunjengomsindo nomthelela.Umsebenzisi kufanele anake ukubheka futhi ahlole isikhathi ukuze aqede ukungasebenzi kahle.Ukugcinwa okulungile nokunengqondo kuphela kweringi yokugebenga kungaqinisekisa ukusebenza kwayo okuvamile, kunikeze ukudlala okuphelele ekusebenzeni kwayo, nokwelula impilo yayo yesevisi.
