Umsebenzi wamathamboitywina yeolikukwahlula ngokubanzi iindawo ezifuna ukuthanjiswa kumacandelo othumelo ukusuka kumacandelo emveliso, ukuze kungavumeli ukuvuza kwe-oyile yokuthambisa.Ngokuqhelekileyo isetyenziselwa i-shafts ejikelezayo kwaye luhlobo lwe-shaft ejikelezayo yokutywinwa komlomo.I-skeleton ifana nemivalo yentsimbi ngaphakathi kumacandelo ekhonkrithi, idlala indima yokomeleza kunye nokuvumela isitywina seoli ukuba sigcine imilo kunye noxinzelelo.Ngokohlobo lwamathambo, lunokwahlulwa lube ngamathambo angaphakathi, i-oil seal, i-oil seal yangaphandle, kunye ne-oyile yangaphakathi nangaphandle eveziweyo.I-skeleton oil seal yenziwe ngerabha ye-nitrile ekumgangatho ophezulu kunye nepleyiti yensimbi, enomgangatho ozinzileyo kunye nobomi benkonzo ende.Isetyenziswa kakhulu kwi-automotive kunye nee-crankshafts zesithuthuthu, ii-camshafts, umahluko, i-absorbers, ii-injini, ii-asi, amavili angaphambili nangasemva, kunye nezinye iindawo.
1. Thintela udaka, uthuli, ukufuma, kunye nezinye izinto ukuba zingangeni kwiibheringi ezivela ngaphandle;
2. Ukunciphisa ukuvuza kweoli yokuthambisa kwiibheringi.Imfuno yokutywinwa kweoli kukuba imilinganiselo (i-diameter yangaphakathi, i-diameter yangaphandle, kunye nobukhulu) kufuneka ihambelane nemimiselo;Funa i-elasticity efanelekileyo ukuze ubambe ngokufanelekileyo i-shaft kwaye unikeze umphumo wokutywina;Kufuneka ikwazi ukumelana nobushushu, inxibe, inamandla afanelekileyo, ixhathise kwimidiya (efana neoli okanye amanzi), kwaye ibe nobomi obude benkonzo.
Ukusetyenziswa okufanelekileyo kweetywina zeoyile kufuneka kuthathelwe ingqalelo kula manqaku alandelayo:
(1) Ngenxa yoyilo kunye nezizathu zesakhiwo, iishafti ezinesantya esiphezulu kufuneka zisebenzise izitywina ze-oyile ezinesantya esiphezulu, ngelixa i-shafts enesantya esiphantsi kufuneka isebenzise i-oyile enesantya esisezantsi.Iimpawu zeoyile ezinesantya esisezantsi azinakusetyenziswa kwiishafti ezinesantya esiphezulu, kwaye ngokuphambeneyo.
(2) Xa ubushushu be-ambient buphezulu, i-polypropylene ester okanye i-silicone, i-fluorine, okanye irabha ye-silicone fluorine kufuneka ikhethwe.Kwaye kufuneka kwenziwe iinzame zokunciphisa ubushushu be-oyile kwitanki yamafutha.Xa usebenzisa kumaqondo aphantsi, irabha ekwazi ukumelana nokubanda kufuneka ikhethwe.
(3) Iimpawu ze-oyile ezinoxinzelelo oluphakathi zinomthamo ophantsi woxinzelelo, kwaye xa uxinzelelo luphezulu kakhulu, uphawu lweoyile luya konakala.Ngaphantsi kweemeko zoxinzelelo olugqithisileyo, iindandatho zenkxaso ezichasene noxinzelelo okanye ukunyanzeliswa kweoli ye-oyile eyomeleziweyo kufuneka kusetyenziswe.
(4) Ukuba i-eccentricity ye-oil seal ngexesha lofakelo inkulu kakhulu xa ihambelana ne-shaft, ukusebenza kwayo kokutywinwa kuya kuhla, ngakumbi xa isantya se-shaft siphezulu.Ukuba i-eccentricity inkulu kakhulu, i-oil seal emile "W" ingasetyenziswa.
(5) I-surface smoothness ye-shaft ichaphazela ngokuthe ngqo ubomi benkonzo yesitywina seoli, oko kukuthi, ukuba i-shaft inobushelelezi obuphezulu, ubomi benkonzo yesitywina seoli buya kuba bude.
(6) Qaphela ukuba kufanele kubekho umlinganiselo othile weoli yokuthambisa kumlebe wetywina leoli.
(7) Ingqalelo ekhethekileyo ifanele inikwe ekuthinteleni uthuli ukuba lungangeni kwitywina leoli.
