Nekuzora kweakavhurika giya madhiraivha anoshandiswa mune akasiyana maindasitiri ekushandisa senge simende uye marasha zvigayo, mavhiri ekutenderera, kana uko mamiriro ekuvharira akaoma, semi-fluid magirisi anowanzo shandiswa pachinzvimbo chemafuta emvura. Pakushandisa girth gear magizi anoshandiswa nesplash kana spray lubrication system. Kusarudzwa kwemafuta akadaro kunopesvedzera pitting life-time uye simba rekutakura mutoro wegiya, pamwe nekupfeka maitiro.
Tsvagiridzo dzakaitwa kuenzanisa pakati pemafuta emvura uye akasiyana semi-fluid (NLGI00) girizi magadzirirwo, akasiyana maererano ne base base mafuta viscosity, thickener rudzi uye kuwedzera kwezvose zviri zviviri mvura uye yakasimba additives. Muedzo unomhanya wekutemerwa kwezviyero zvakasiyana-siyana zvakaitwa pa-back-to-back gear test rigs; iyo schematic setup yetest rig inoratidzwa pazasi.
Mhedzisiro dzebvunzo dzinoratidza kuti magiya magiya eNLGI 00 kuwirirana anoratidza anenge hupenyu hwakafanana hwekugomba sevamwe vavo mafuta ekutanga. Uyezve, iyo kinematic viscosity yeoiri yepasi inoratidza pesvedzero yakakosha pakupinza hupenyu hweakadaro NLGI 00 giredhi magirisi. Kuwedzerwa kweiyo yakakosha synthetic graphite kune yakadaro giya girisi kwakatungamira kuderera kwehupenyu hwegomba uye kupfeka kwakanyanya. Mhedzisiro yemuyedzo inoratidzawo kuti gomba rinotakura huwandu hweaya magirisi anowirirana ne kinematic viscosity ye base base mafuta. Kushandisa yakakwira base mafuta viscosity, kureba kwegomba hupenyu uye yakakwirira gomba rekutakura mutoro wekutakura wakawanikwa. Kune semi-fluid giya magiya, kuverengerwa kwegomba rekutakura mutoro wekutakura zvinoenderana neISO 6336 uchishandisa viscosity ye base base mafuta inopindirana nemhedzisiro yebvunzo inoshanda. Iwo maedzo ekuongorora maitiro ekupfeka eakasiyana semi-fluid giya magiya akagadzirwa mukupfeka bvunzo A/2.8/50 pahwaro hwe ISO 14635-3 uye ISO 14635-1. Zvikamu zvina zvakasiyana zvekupfeka zvakatsanangurwa bvunzo yekutsungirira kwemaawa zana uye kupatsanurwa kwakaitwa zvichienderana nekupfeka kwemari papioni uye vhiri. Kazhinji, anenge ese akaferefetwa mafuta ekuzora, kunze kwemagirosi ane mafuta akasimba, anoratidza kupera kushoma muzvikamu zvese zvekuyedzwa. Iyo influence ye base base mafuta viscosity inogona kuoneka mukuti magirosi ane epamusoro base mafuta viscosities anoratidza yakaderera kupfeka. Iko pesvedzero yekumisikidzwa kweiyo thickener uye rudzi rwehukobvu hunenge husina basa, asi girisi ine sipo yealuminium yakaoma inoratidza ingori shoma shoma yekupfeka ichienzaniswa neiyo lithium sipo-yakakora chikamu chikamu. Musiyano wakanyanya kukosha unogona kuoneka mukurudziro yehuwandu uye mhando yemafuta akasimba. Magirosi ane girasi rekugadzira anoratidza mari dzekupfeka dzakakwira - dzinoenderana nehuwandu hwegirafu mugirizi - zvichienzaniswa negirisi rimwe chete risina mafuta ekuzora akasimba. Pakupera kwedanho rekuyedza girisi ine 4.2% graphite inoratidza yakapetwa katatu- yakakwira yekupfeka sum pane yepasi girisi. Uye nehuwandu hwe graphite - 11.1% -kupfeka kwakawedzera kusvika pachiyero chepamusoro kasere kana zvichienzaniswa negirisi isina kusimba. Uyu muitiro wakasimbiswawo mukuedzwa kwokutsungirira; kureva - iyo yakawanda graphite, yakakwirira kupfeka. Kune rimwe divi, girisi ine 4.2% yemolybdenum disulphide inoratidza kupfeka kwakafanana. Kana iyo spur gearset ikatanga kutenderera, girisi padivi pegiya rinobva raraswa uye haridzokeri kune iro giya nekuda kwekushaikwa kweyakakwana yekuzadza michina. Mukaha unoumbwa pakati pemagiya anotenderera negirisi sump. Hapana girisi nyowani inoyerera kubva sump ichienda kune giya nekuda kwekusimba kwayo. Kushaikwa kwekuzora uye kutonhora kunogona kucherechedzwa izvo zvinogona kutungamira kune yakanyanya kuwanda tembiricha mumagiya uye, pakupedzisira, kune scuffing. Chete chishoma chegirizi chinotora chikamu mukuzora. Kudhindisa kunoitika zvakanyanya pamakumi mana ne50% mazinga ekuzadza uye kune yakaoma prod kune base grisi mushure meyedzo yedanho uye kungopfeka zvishoma zvishoma mushure mebvunzo yekutsungirira.
Mune imwe mamiriro akasiyana, ekuzora madiki, akavharirwa magiya madhiraivha anoshandiswa mumidziyo yemagetsi kana mune zvekurapa, pamwe nekuzora mabhokisi egiya madiki mumamiriro akaoma ekuvharisa anofarirwa, kazhinji eNLGI 1 kana 2 giredhi kuenderana. . Sarudzo yerudzi rwegirisi uye nhanho yekuzadza inokanganisa kushanda zvakanaka, kutakura-kuremedza huwandu uye kupisa kupisa mubhokisi regiya.
