Ezimweni eziningi zokukhiqizwa kwezimboni kanye nokusebenza kwemishini yemishini, ama-bearings ayingxenye ebalulekile, futhi ukuzinza kokusebenza kwawo kuhlobene ngokuqondile nokusebenza okuvamile kwalo lonke uhlelo. Kodwa-ke, lapho kubanda kubanda, kuzovela uchungechunge lwezinkinga eziyinkimbinkimbi nezinzima, ezizoba nomthelela omubi kakhulu ekusebenzeni okujwayelekile kokuthwala.
Ukuncipha Kwempahla
Amabhorelo ngokuvamile enziwe ngensimbi (isib. insimbi), enendawo yokwandisa nokuncipha kwe-thermal. Izingxenye zeukuzala, njengamandandatho angaphakathi nangaphandle, izakhi ezigoqayo, zizoshwabana Ezindaweni ezibandayo. Ukuze uthole usayizi ojwayelekile, ama-diameter angaphakathi nangaphandle angase anciphe ngama-microns ambalwa lapho izinga lokushisa lehla lisuka ku-20°C liye ku-20°C. Lokhu kushwabana kungabangela ukucaciswa kwangaphakathi kwe-bearing kube kuncane. Uma imvume incane kakhulu, ukungqubuzana phakathi komzimba ogoqayo kanye namasongo angaphakathi nangaphandle kuzokwanda ngesikhathi sokusebenza, okuzothinta ukuguquguquka kokujikeleza kokuthwala, ukwandisa ukumelana, kanye ne-torque yokuqala yemishini.
Ukuqina Ukushintsha
Isimo sezulu esibandayo sizokwenza ukuthi ubulukhuni bezinto ezithwalayo buguquke ngokwezinga elithile. Ngokuvamile, izinsimbi ziba brittle emazingeni okushisa aphansi, futhi ubulukhuni bazo bukhuphuka ngokuqhathaniswa. Endabeni yokuthwala insimbi, nakuba ukuqina kwayo kuhle, kusancishiswa ezindaweni ezibandayo kakhulu. Uma ukuthwala kubhekene nemithwalo yokushaqeka, lolu shintsho ebukhuni lungabangela ukuthi ukuthwala kuthambekele ekuqhekekeni noma ngisho nokuphuka. Isibonelo, kuma-bearings wemishini yezimayini yangaphandle, uma ingaphansi komthelela we-ore ewayo esimweni sezulu esibandayo, cishe izolimala kunezinga lokushisa elivamile.
Ukushintsha Ukusebenza Kwamafutha
Ukugcoba kungenye yezinto ezibalulekile zokuqinisekisa ukusebenza kokusebenza kwama-bearings. Esikhathini esibandayo, i-viscosity yamafutha izokhula. Amafutha avamile angase abe mkhulu futhi abe noketshezi oluncane. Lokhu kwenza kube nzima ukwenza ifilimu kawoyela enhle phakathi komzimba ogoqayo kanye nemigwaqo yomjaho wokuthwala. Ku-motor bearing, amafutha angagcwaliswa kahle kuzo zonke izikhala ngaphakathi ekushiseni okujwayelekile. Njengoba izinga lokushisa lincipha, amafutha ayanamathela, futhi umzimba ogoqayo awukwazi ukuletha amafutha ngokufanayo kuzo zonke izingxenye zokuthintana ngesikhathi sokugoqa, okwandisa ukungqubuzana nokuguga, futhi isivinini sawo sokujikeleza singase siguquguquke, okulimaza ikhwalithi ephezulu kanye nokunemba kobukhulu be-dimensional. izingxenye ezenziwe ngomshini. Ezimweni ezimbi kakhulu, kungase kuholele ekushiseni ngokweqile noma ngisho nokubamba i- bear.
Impilo Yesevisi Efinyeziwe
Inhlanganisela yalezi zici, ukungqubuzana okwandisiwe, ukuqina komthelela oncishisiwe kanye nokugcotshwa okungekuhle kwamabheringi esimweni sezulu esibandayo kungasheshisa ukuguga. Ngaphansi kwezimo ezivamile, ama-bearings angakwazi ukugijima izinkulungwane zamahora, kodwa ezindaweni ezibandayo, ngenxa yokwenyuka kokuguga, angase asebenze amahora angamakhulu ambalwa azohluleka, njengokugqoka komzimba okuginqikayo, umgodi womjaho, njll., okufinyeza kakhulu insizakalo. impilo yama-bearings.
Lapho sibhekene nale miphumela emibi yesimo sezulu esibandayo kuma-bearings, kufanele siyidambise kanjani?
Khetha Gcoba Ngakwesokudla bese Ulawula Inani
Esimweni sezulu esibandayo, gcoba ngokusebenza kahle kwezinga lokushisa eliphansi kufanele kusetshenziswe. Lolu hlobo lwamafutha lungakwazi ukugcina uketshezi oluhle emazingeni okushisa aphansi, njengemikhiqizo equkethe izithasiselo ezikhethekile (isb., amafutha asekelwe ku-polyurethane). Azikho i-viscous kakhulu futhi zinganciphisa ngempumelelo ukungqubuzana kwama-bearings ngesikhathi sokuqala nokusebenza. Ngokuvamile, indawo yokuthela (izinga lokushisa eliphansi kakhulu lapho isifanekiso sikawoyela esipholile singageleza ngaphansi kwezimo ezishiwo zokuhlola) samafutha ezinga lokushisa eliphansi liphansi kakhulu, futhi amanye angaba ngaphansi kuka -40°C noma ngisho ngaphansi, ngaleyo ndlela kuqinisekiswe ukuthambisa okuhle kwama-bearings ngisho nasesimweni sezulu esibandayo.
Inani elifanele lokugcwaliswa kwamafutha libalulekile ekuthwaleni ukusebenza emakhazeni. Amafutha amancane kakhulu azoholela ekugcobiseni okwanele, kuyilapho ukugcwalisa ngokweqile kuzodala ukuthi i-bearing ikhiqize ukumelana nokuyaluza okukhulu ngesikhathi sokusebenza. Esikhathini esibandayo, ukugcwaliswa ngokweqile kufanele kugwenywe ngenxa yokwanda kwe-viscosity yamafutha. Ngokuvamile, kuma-bearings amancane naphakathi nendawo, inani lokugcwalisa amafutha limayelana ne-1/3 - 1/2 yendawo yangaphakathi yokuthwala. Lokhu kuqinisekisa ukugcoba futhi kunciphisa ukumelana okubangelwa amafutha amaningi.
Faka esikhundleni samafutha njalo futhi uqinise uphawu
Ngisho noma kusetshenziswa amafutha afanele, ngokuhamba kwesikhathi kanye nokusebenza kokuthwala, amafutha azongcoliswa, afakwe i-oxidized nokunye. Lezi zinkinga zingase zibe zimbi nakakhulu lapho kubanda. Kunconywa ukuthi kufinyezwe umjikelezo wokushintsha amafutha ngokuya ngokusebenza kwemishini kanye nezimo zemvelo. Isibonelo, endaweni evamile, amafutha angashintshwa kanye njalo ezinyangeni eziyisithupha, futhi ngaphansi kwezimo ezibandayo, angafinyezwa njalo ezinyangeni ezi-3 - 4 ukuqinisekisa ukuthi ukusebenza kwamafutha kuhlala kusesimweni esihle.
Ukubekwa uphawu okuhle kungavimbela umoya obandayo, umswakama kanye nokungcola ekungeneni. Esikhathini esibandayo, ungasebenzisa izimpawu eziphezulu zokusebenza, ezifana ne-double lip seal noma i-labyrinth seal. I-Double-lip seal inezindebe zangaphakathi nezingaphandle zokuvimba kangcono izinto zangaphandle kanye nomswakama ngaphandle. Ama-Labyrinth seal anesakhiwo sesiteshi esiyinkimbinkimbi esenza kube nzima kakhulu ukuthi izinto zangaphandle zingene ku-bearing. Lokhu kunciphisa umonakalo ekuthwaleni isakhiwo sangaphakathi esibangelwa ukunwetshwa kwe-icing yamanzi, kanye nokuvimbela ukungena kokungcola okuholela ekukhuleni kokugqoka okuthwala.
Ingaphezulu le-bearing ingafakwa ngengubo evikelayo, njengopende lwe-antirust noma i-coating yokuvikela ephansi. I-Antirust paint ingavimbela ukugqwala ezimweni ezibandayo noma ezimanzi, kuyilapho i-cryogenic protective coatings inganciphisa imiphumela yokushintsha kwezinga lokushisa ezintweni ezithwala. Izembatho ezinjalo zisebenza njengomnakekeli wokuvikela indawo ethwalayo ekugugulekeni okuqondile ezindaweni ezishisayo futhi kusiza ukunciphisa izinguquko ezimpahleni ezibonakalayo ngenxa yokushintsha kwezinga lokushisa.
Izisetshenziswa Ukufudumeza
Ukufudumeza iyunithi yonke ngaphambi kokuyiqala kuyindlela ephumelelayo. Kweminye imishini emincane, ingafakwa “Ku-Conservatory” isikhathi esithile ukuze kukhuphuke izinga lokushisa elithwalayo. Okokusebenza okukhulu, njengama-cranes amakhulu athwele, kungasetshenziswa ukwengeza itheyiphu yokushisa noma ifeni eshisayo noma ezinye izinto zokusebenza ukuze kushiswe ngaphambili ingxenye ephethe. Ukushisa kwangaphambi kokushisa ngokuvamile kungalawulwa cishe ku-10 - 20 ° C, okungenza izingxenye ezithwalayo zande futhi zibuyele ekuvunyelweni okujwayelekile, kuyilapho kunciphisa i-viscosity yamafutha, evumela ukuqala kahle kwemishini.
Kwamanye ama-bearings angahlakazwa, ukushisa okugeza uwoyela kuyindlela enhle. Beka ama-bearings emafutheni okugcoba ashiswe ekushiseni okufanelekile, ukuze ama-bearings ashise ngokulinganayo. Le ndlela ayigcini nje ukwandisa izinto ezithwalayo, kodwa futhi ivumela i-lubricant ukuthi ingene ngokugcwele imvume yangaphakathi yokuthwala. Izinga lokushisa likawoyela elishisiwe ngokuvamile liba ngu-30 - 40 ° C, isikhathi singalawulwa ngokuhambisana nobukhulu bokuthwala nezinto ezibonakalayo kanye nezinye izici cishe amahora angu-1 - 2, okungathuthukisa ngempumelelo ukuthwala esimweni sezulu esibandayo sokuqala ukusebenza.
Nakuba ukubanda kuletha izinkinga ekuthwaleni, kungakha umugqa wokuzivikela oqinile ngokukhetha amafutha alungile, ukuvala uphawu nokuvikela ukushisa kwangaphambili. Lokhu akuqinisekisi kuphela ukusebenza okuthembekile kwama-bearings ekushiseni okuphansi, kwandisa ukuphila kwabo, kodwa futhi kukhuthaza ukuthuthukiswa okuzinzile kwemboni, ukuze i-TP ikwazi ukuhamba ngokuthula ibheke ohambweni olusha lwezimboni.
TP,Ukuthwala isondofuthiizingxenye zezimotoumkhiqizi kusukela ngo-1999. Uchwepheshe wezobuchwepheshe we-Automotive Aftermarket!Thola isisombululo sezobuchwephesheManje!
