Ukuzinza kokushisa, ukumelana ne-oxidation kanye nokweqisa kwezinga lokushisa kufanele kucatshangelwe lapho kukhethwa amafutha okufaka ukushisa okuphezulu.Ezinhlelweni ezingezona zokuvuselela, lapho izinga lokushisa elisebenzayo lingaphezu kuka-121 ° C, kubalulekile ukukhetha uwoyela wamaminerali acwengekile noma uwoyela owenziwe ozinzile njengawoyela wesisekelo.Ithebula 28. Izinga lokushisa lamafutha Ukungcola Izinhlayiya eziqhumayo Lapho izinhlobo zama-abrashi zisebenza endaweni ehlanzekile, umthombo oyinhloko wokulimala ukukhathala kokuthintana okugoqekayo.Kodwa-ke, lapho ukungcola kwezinhlayiyana kungena ohlelweni lokuthwala, kungabangela ukulimala okufana nenyongo, into eyenza kube mfishane ukuphila okuzalayo.I-Wear ingaba imbangela enkulu yokuthwala umonakalo lapho ukungcola endaweni noma insimbi igqamuka ezingxenyeni ezithile zohlelo lokusebenza kungcolisa okokugcoba.Uma, ngenxa yokungcoliswa kwengxenye ye-lubricant, ukugqoka okuthwala kuba okuphawulekayo, ubukhulu obubalulekile bokuthwala bungashintsha, okungathinta ukusebenza komshini.

Amabhereli asebenza kuzinto zokuthambisa ezingcolile anamazinga okuguga aphezulu aphezulu kunama-lubricant angangcolisiwe.Kodwa-ke, leli zinga lokuguga liyancipha ngokushesha uma kungekho okunye ukungena kwe-lubricant, njengoba ukungcola kuncipha ngosayizi njengoba kudlula ezindaweni ezithintana nazo ngesikhathi sokusebenza okuvamile.Umswakama kanye nomswakama yizici ezibalulekile ekuthwaleni umonakalo.Amafutha anganikeza isivikelo emonakalweni onjalo.Amafutha athile, afana ne-calcium complex kanye ne-aluminium complex greases, anokumelana namanzi okuphezulu kakhulu.Amafutha asuselwa ku-sodium ayancibilika emanzini ngakho-ke awakwazi ukusetshenziswa ezinhlelweni eziqukethe amanzi.Kungakhathaliseki ukuthi amanzi ancibilikisiwe noma amanzi amisiwe kuwoyela wokugcoba, angaba nomthelela obulalayo ekuthwaleni impilo yokukhathala.Amanzi angagqwala ama-bearings, futhi ukugqwala kunganciphisa ukuphila kokukhathala.Indlela eqondile amanzi anganciphisa ngayo impilo yokukhathala ayiqondwa ngokugcwele.Kodwa kuye kwaphakanyiswa ukuthi amanzi angangena kuma-microcracks emigwaqweni ethwalayo, ebangelwa ukucindezeleka okuphindaphindiwe kwe-cyclic.Lokhu kungaholela ekugqwaleni kanye ne-hydrogen embrittlement yama-microcracks, kunciphisa kakhulu isikhathi esidingekayo ukuze le mifantu ikhule ibe osayizi abangamukelekile bokuqhekeka.Uketshezi olusekelwe emanzini olufana ne-water glycol kanye nama-emulsions aguquliwe nawo abonise ukuncipha kokuthwala ukuphila kokukhathala.Nakuba amanzi aphuma kuwo engafani namanzi angcolile, imiphumela isekela izimpikiswano zangaphambili zokuthi amanzi angcolisa izinto zokugcoba.Zombili iziphetho zomkhono ofakwayo kufanele zime mpo, indawo yangaphakathi nengaphandle kufanele ihlanzwe kahle, futhi umkhono kufanele ube mude ngokwanele ukuze kuqinisekiswe ukuthi ukuphela komkhono kusekude kunokuphela kwe-shaft ngemva kokufakwa kwe-bearing.Ububanzi bangaphandle kufanele bube buncane kunobubanzi obungaphakathi bendlu.I-Bore diameter engencane kunobubanzi behlombe lendlu okutuswe ku-Timken® Spherical Roller Bearing Selection Guide (Oda No. 10446C) ku-timken.com/catalogs Amandla adingekayo ukufaka ngokucophelela i-bearing ku-shaft futhi uqinisekise ukuthi perpendicular to the centerline of the shaft.Faka ingcindezi engaguquki ngesigaxa sesandla ukuze ubambe ibhande liqine ngokumelene ne-shaft noma ihlombe lendlu.
