Uyazi ukuthi isimo sezulu esibandayo senzani kuma-wheel bearings? Futhi ungawunciphisa kanjani lo mphumela omubi?

Ezimweni eziningi zokukhiqiza kwezimboni kanye nokusebenza kwemishini yemishini, ama-bearings ayizingxenye ezibalulekile, futhi ukuzinza kokusebenza kwawo kuhlobene ngqo nokusebenza okuvamile kwesistimu yonke. Kodwa-ke, lapho kubanda, kuzovela uchungechunge lwezinkinga eziyinkimbinkimbi nezinzima, ezizoba nomthelela omubi ekusebenzeni okuvamile kwe-bearings.

 

Ukuncipha Kwezinto Ezibalulekile

Ama-bearings ngokuvamile enziwa ngensimbi (isb. insimbi), enesimo sokwanda nokuncipha kokushisa. Izingxenye zeibhere, njengendandatho zangaphakathi nezangaphandle, izakhi ezigoqayo, zizoncipha Ezindaweni ezibandayo. Ku-bearing enobukhulu obujwayelekile, ububanzi bangaphakathi nangaphandle bungase bunciphe ngama-micron ambalwa lapho izinga lokushisa lehla kusuka ku-20°C kuya ku-20°C. Lokhu kuncipha kungabangela ukuthi i-clearance yangaphakathi ye-bearing ibe yincane. Uma i-clearance incane kakhulu, ukungqubuzana phakathi komzimba ogoqayo kanye nendandatho zangaphakathi nezangaphandle kuzokwanda ngesikhathi sokusebenza, okuzothinta ukuguquguquka kokujikeleza kwe-bearing, kwandise ukumelana, kanye ne-torque yokuqala yemishini.

Ushintsho Lobulukhuni

Isimo sezulu esibandayo sizokwenza ubulukhuni bezinto zokuthwala bushintshe ngezinga elithile. Ngokuvamile, izinsimbi ziyaqhekeka emazingeni okushisa aphansi, futhi ubulukhuni bazo bukhuphuka ngokulinganisela. Endabeni yensimbi yokuthwala, yize ukuqina kwayo kukuhle, kusancishiswa ezindaweni ezibandayo kakhulu. Lapho i-bearing ibhekene nemithwalo yokushaqeka, lolu shintsho ebulukhunini lungabangela ukuthi i-bearing ithambekele kakhulu ekuqhekekeni noma ngisho nasekuqhekekeni. Isibonelo, kuma-bearing emishini yokumba yangaphandle, uma ibhekene nokushaywa yi-ore ewayo emakhazeni, kungenzeka ukuthi yonakale kunasemazingeni okushisa ajwayelekile.

Ushintsho Lokusebenza Kwamafutha

I-Grease ingenye yezinto ezibalulekile ukuqinisekisa ukusebenza kahle kwama-bearings. Esimweni sezulu esibandayo, i-viscosity yamafutha izokwanda. I-grease evamile ingaba nkulu futhi ingabi manzi kakhulu. Lokhu kwenza kube nzima ukwakha ifilimu kawoyela enhle phakathi komzimba ogoqayo kanye nemigwaqo yomjaho we-bearings. Ku-bearings yemoto, i-grease ingagcwaliswa kahle kuzo zonke izikhala ngaphakathi ekushiseni okuvamile. Njengoba izinga lokushisa lehla, i-grease iba namathela, futhi umzimba ogoqayo awukwazi ukuletha i-grease ngokulinganayo kuzo zonke izingxenye zokuxhumana ngesikhathi sokugoqa, okwandisa ukungqubuzana nokuguguleka, futhi ijubane layo lokujikeleza lingashintshashintsha, okulimaza ikhwalithi yobuso kanye nokunemba kobukhulu bezingxenye ezifakwe emshinini. Ezimweni ezimbi kakhulu, kungaholela ekushiseni ngokweqile noma ngisho nasekubambeni i-bearings.

Impilo Yesevisi Efushane

Inhlanganisela yalezi zici, ukwanda kokungqubuzana, ukuncipha kokuqina komthelela kanye nokugcotshwa okungekuhle kwama-bearings esimweni sezulu esibandayo kungasheshisa ukuguguleka kwama-bearings. Ngaphansi kwezimo ezivamile, ama-bearings angase akwazi ukusebenza izinkulungwane zamahora, kodwa ezindaweni ezibandayo, ngenxa yokuguguleka okukhulu, angasebenza amahora ambalwa azohluleka, njengokuguga komzimba okugoqekayo, umgodi womjaho, njll., okunciphisa kakhulu impilo yenkonzo yama-bearings.

 

Njengoba sibhekene nale miphumela emibi yesimo sezulu esibandayo kuma-bearings, kufanele siyinciphise kanjani?

Khetha i-Grease Efanele bese Ulawula Inani

Esimweni sezulu esibandayo, kufanele kusetshenziswe igrisi esebenza kahle ekushiseni okuphansi. Lolu hlobo lwegrisi lungagcina uketshezi oluhle emazingeni okushisa aphansi, njengemikhiqizo equkethe izithasiselo ezikhethekile (isb., amafutha asekelwe ku-polyurethane). Awaqinile kakhulu futhi anganciphisa ngempumelelo ukungqubuzana kwama-bearings ngesikhathi sokuqala nokusebenza. Ngokuvamile, iphuzu lokuthulula (izinga lokushisa eliphansi kakhulu lapho isampula epholile kawoyela ingageleza khona ngaphansi kwezimo zokuhlola ezicacisiwe) lamafutha okushisa aphansi liphansi kakhulu, kanti amanye angaba ngaphansi kuka--40°C noma ngaphansi, ngaleyo ndlela kuqinisekiswe ukugcotshwa okuhle kwama-bearings ngisho nasesimo sezulu esibandayo.

Inani elifanele lokugcwaliswa kwamafutha libalulekile futhi ekusebenzeni kwama-bearing uma kubanda. Ukugcoba okuncane kakhulu kuzoholela ekugcotshweni okunganele, kanti ukugcwalisa ngokweqile kuzobangela ukuthi i-bearing ikhiqize ukumelana okukhulu kokushukuma ngesikhathi sokusebenza. Uma kubanda, ukugcwalisa ngokweqile kufanele kugwenywe ngenxa yokwanda kwe-viscosity yamafutha. Ngokuvamile, kuma-bearing amancane naphakathi nendawo, inani lokugcwalisa amafutha lingaba yi-1/3 - 1/2 yesikhala sangaphakathi se-bearing. Lokhu kuqinisekisa ukugcotshwa futhi kunciphisa ukumelana okubangelwa amafutha amaningi.

 

Shintsha Amafutha Njalo Futhi Uqinise Ukuvalwa
Ngisho noma kusetshenziswa amafutha afanele, ngokuhamba kwesikhathi kanye nokusebenza kwe-bearing, amafutha azongcoliswa, ancibilikiswe njalo njalo. Lezi zinkinga zingase zibe zimbi kakhulu uma kubanda. Kunconywa ukuthi kufushaniswe umjikelezo wokushintsha amafutha ngokuya ngokusebenza kwemishini kanye nezimo zemvelo. Isibonelo, endaweni evamile, amafutha angashintshwa kanye njalo ezinyangeni eziyisithupha, futhi ngaphansi kwezimo ezibandayo, angafinyezwa abe njalo ezinyangeni ezi-3 kuya kwezi-4 ukuqinisekisa ukuthi ukusebenza kwamafutha kuhlala kusesimweni esihle.
Ukuvala kahle kungavimbela umoya obandayo, umswakama kanye nokungcola kubhereyi. Esimweni sezulu esibandayo, ungasebenzisa izivalo ezisebenza kahle kakhulu, njenge-double lip seal noma i-labyrinth seal. Izivalo ze-double-lip seal zinezindebe zangaphakathi nezangaphandle ukuze zivimbele kangcono izinto zangaphandle kanye nomswakama ngaphandle. Izivalo ze-labyrinth zinesakhiwo esiyinkimbinkimbi sesiteshi esenza kube nzima kakhulu ngezinto zangaphandle ukungena kubhereyi. Lokhu kunciphisa umonakalo esakhiweni sangaphakathi sebhereyi okubangelwa ukwanda kweqhwa lamanzi, kanye nokuvimbela ukungena kokungcola okuholela ekugugeni okukhulu kwebhereyi.
Ubuso bebheri bungambozwa ngengubo evikelayo, njengopende wokulwa nokugqwala noma ingubo evikelayo yokushisa okuphansi. Upende wokulwa nokugqwala ungavimbela ibheri ukuthi ingagqwali ezimweni ezibandayo noma ezimanzi, kuyilapho izambatho ezivikelayo ezi-cryogenic zinganciphisa imiphumela yokushintsha kwezinga lokushisa ezintweni ezithwalayo. Izingubo ezinjalo zisebenza njengomvikeli wokuvikela ubuso bebheri ekugugulekeni okuqondile ezindaweni ezishisa kakhulu futhi zisiza ekunciphiseni izinguquko ezakhiweni zezinto ngenxa yokushintsha kwezinga lokushisa.
Ukufudumeza Imishini
Ukufudumala yonke iyunithi ngaphambi kokuqala kuyindlela ephumelelayo. Kweminye imishini emincane, ingafakwa ku-“Conservatory” isikhathi esithile ukuze kuvunyelwe izinga lokushisa lebheriyali likhuphuke. Kwemishini emikhulu, njenge-cranes ezinkulu, kungasetshenziswa ukwengeza i-heat tape noma i-hot fan noma eminye imishini yokushisa ingxenye yebheriyali kusengaphambili. Izinga lokushisa lokushisa ngokuvamile lingalawulwa cishe ku-10 - 20°C, okungenza izingxenye zebheriyali zande futhi zibuyele endaweni evamile, kuyilapho kunciphisa i-viscosity yamafutha, okusiza ukuqala kahle kwemishini.
Kwamanye ama-bearing angahlukaniswa, ukushisa kusengaphambili ngebhavu lamafutha kuyindlela enhle. Faka ama-bearing ku-oyili wokugcoba oshiswayo ezingeni lokushisa elifanele, ukuze ama-bearing ashiswe ngokulinganayo. Le ndlela ayigcini nje ngokwandisa izinto zokuthwala, kodwa futhi ivumela i-lubricant ukuthi ingene ngokugcwele ngaphakathi kwe-bearing. Izinga lokushisa likawoyela oshiswayo ngokuvamile lingaba ngu-30 - 40°C, isikhathi singalawulwa ngokuya ngobukhulu be-bearing nezinto kanye nezinye izinto cishe emahoreni angu-1 - 2, okungathuthukisa ngempumelelo i-bearing ekusebenzeni kokuqala kwesimo sezulu esibandayo.

Nakuba umkhuhlane uletha izinkinga kubhereyi, ungakha umugqa wokuzivikela oqinile ngokukhetha igrisi efanele, ukuvala kanye nokuvikela ukushisa kusengaphambili. Lokhu akugcini nje ngokuqinisekisa ukusebenza okuthembekile kwamabhereyi emazingeni okushisa aphansi, kwandise impilo yawo, kodwa futhi kukhuthaza intuthuko ezinzile yemboni, ukuze i-TP ikwazi ukuhamba ngokuthula ibheke ohambweni olusha lwezimboni.
