1. Ukusilela kokunyibilika kweCrankshaft

Xa imveliso ye-crankshaft inyibilika, ukusebenza kwe-injini emva kokuba impazamo yenzekile kukuba: isandi sokunkqonkqoza kwesinyithi esibuthuntu nesinamandla siya kukhutshwa kwibheringi engundoqo enyibilikisiweyo. Ukuba zonke iibheringi ziyanyibilika okanye zikhululekile, kuya kubakho isandi esicacileyo esithi "dang, pang". Unobangela wokusilela

(1) Uxinzelelo lweoyile yokuthambisa alwanelanga, ioyile yokuthambisa ayinakucudisa phakathi kweshaft kunye nokuthwala, ukuze i-shaft kunye nokuthwala kukwimeko eyomileyo okanye eyomileyo, ebangela ukuba ubushushu bomthwalo bunyuke. kunye ne-anti-friction alloy iyanyibilika.

(2) Ipaseji yeoli yokuthambisa, umqokeleli we-oyile, isihluzi se-oyile, njl.njl. zithintelwe bubumdaka, kwaye ivelufa yokudlula kwisihluzi ayinakuvuleka (ukulayisha kwangaphambili kwesihluzi sevalve kukhulu kakhulu okanye isihluzi se-oyile, njl.njl. ubumdaka, njl.njl.), Okubangele uphazamiseko lonikezelo lweoyile yokuthambisa.

(3) Umsantsa phakathi kweshafti kunye nokuthwala umncinci kakhulu ukuba wenze ifilimu yeoli; ukuthwala kufutshane kakhulu kwaye akunasiphazamiso kunye nomngxuma wezindlu ezithwele, kubangela ukuba ukuthwala ukujikeleza kumngxunya wezindlu, ukuvala umngxuma wokuhamba kweoli kwi-bearing house hole, kunye nokuphazamisa ukunikezelwa kweoli yokuthambisa.

(4) Ubungqukuva bejenali yecrankshaft imbi kakhulu. Ngexesha lenkqubo yokuthambisa, kunzima ukwenza ifilimu yeoli ethile ngenxa yokuba ijenali ayingqukuva (ukuthwala imvume ngamanye amaxesha kukhulu kwaye ngamanye amaxesha kuncinci, kwaye ifilimu yeoli ngamanye amaxesha ityebile kwaye ngamanye amaxesha ibhityile), okukhokelela ekuthanjisweni kakuhle.

(5) Ukuguqulwa komzimba okanye impazamo yokwenziwa komsebenzi, okanye ukugotywa kwe-crankshaft, njl. njl., yenza ukuba imigca esembindini yebheringi nganye engundoqo ingangqamani, nto leyo ebangela ukuba ubukhulu befilimu ye-oyile yebheringi nganye ingalingani xa i-crankshaft ijikeleza, kwaye ide ibe kukukhuhlana okomileyo. chaza ukunyibilikisa ukuthwala.

(6) Ubungakanani be-oyile yokuthambisa kwipani yeoli ayonelanga kwaye nobushushu be-oyile buphezulu kakhulu, okanye i-oyile yokuthambisa ixutywa ngamanzi okanye ngepetroli, okanye i-oyile yokuthambisa yomgangatho ophantsi okanye uphawu olungahambelaniyo luyasetyenziswa.

Ukuthintela iimpazamo kunye neendlela zokusombulula ingxaki

(1) Ngaphambi kokufaka i-injini yendibano, nikela ingqalelo ekucoceni nasekuhlolweni kwepaseji yeoli yokuthambisa (hlamba ngamanzi anoxinzelelo oluphezulu okanye umoya), susa inkunkuma evalela umqokeleli wokucoca, kwaye uqinise ukugcinwa kwesihluzo esirhabaxa ukunqanda. icebo lokucoca ulwelo lokuvala kunye nevalve yokudlula ukungasebenzi.

(2) Umqhubi kufuneka aqwalasele ubushushu be-injini kunye noxinzelelo lweoyile yokuthambisa nangaliphi na ixesha, kwaye ajonge ingxolo engaqhelekanga enjinini; jonga ubungakanani kunye nomgangatho weoyile yokuthambisa phambi kokuba usishiye isithuthi.

(3) Ukuphucula umgangatho wokugcinwa kwe-injini kunye nokomeleza ukuhlolwa kokulungiswa kwangaphambili kweendawo ezisisiseko.

(4) Ukukrwelwa kwebheringi engundoqo ye-crankshaft kufuneka yenze umbindi womngxuma ngamnye ongundoqo wendlu ube phakathi. Kwimeko yokuphambuka okuncinci kunye nokulungiswa ngokulangazelela, indlela yokukrazula yokuqala yokulungisa umgca othe tye ingasetyenziswa. Umsebenzi wokukhuhla unxulumene nentsimbi yokuqhagamshela. Iphantse yafana.

2. Ibhereyi ephambili yecrankshaft yenza ingxolo

Ukusebenza kwe-injini emva kwengxolo evela kwi-crankshaft bearing ibangelwa yimpembelelo yejenali ye-crankshaft engundoqo kunye nokuthwala. Xa i-bearing engundoqo inyibilika okanye iwe, injini iya kungcangcazela kakhulu xa i-accelerator pedal idandathekile kakhulu. Ukuthwala okuphambili kugugile, kwaye i-radial clearance inkulu kakhulu, kwaye kuya kubakho isandi esinzima nesincinci sokunkqonkqoza. Okukhona isantya senjini siphezulu, kokukhona isandi esikhulu, kunye nesandi sinyuka ngokunyuka komthwalo. Unobangela wokusilela

(1) Iibheringi kunye neejenali zinxitywe kakhulu; iibholiti zokuqinisa i-cover cover ayivalwanga ngokuqinileyo kwaye ikhululwe, eyenza ukucaca okuhambelanayo phakathi kwe-crankshaft kunye nokuthwala kukhulu kakhulu, kwaye ezi zimbini zenza isandi xa zidibana.

(2) I-alloy ethweleyo iyanyibilika okanye iyawa; ukuthwala kude kakhulu kwaye ukuphazamiseka kukhulu kakhulu, kubangela ukuba ukuthwala kuphuke, okanye ukuthwala kufutshane kakhulu ukuba kubekwe kakubi kwaye kukhululekile kumngxuma wezindlu ezithwele, kubangela ukuba ezimbini zingqubane.

Ukuthintela iimpazamo kunye neendlela zokusombulula ingxaki

(1) Ukuphucula umgangatho wogcino lwe-injini. Iibholiti zokulungisa i-cover cover kufuneka ziqiniswe kwaye zitshixiwe. Ukuthwala akufanele kube kude kakhulu okanye kufutshane kakhulu ukuqinisekisa umlinganiselo othile wokuphazamiseka.

(2) Ibakala lesithambiso esisetyenzisiweyo lifanele libe lichanekile, kungabikho sisithambiso esingaphantsi kufuneka sisetyenziswe, kwaye ubushushu obufanelekileyo be-lubricant noxinzelelo kufuneka zigcinwe.

(3) Gcina imeko efanelekileyo yokusebenza kwenkqubo yokuthambisa, buyisela ioli yokuthambisa ngexesha elifanelekileyo, kwaye ugcine isihluzo se-oyile yokuthambisa rhoqo.

(4) Xa uqhuba, umqhubi ufanele anikele ingqalelo ekutshintsheni koxinzelelo lweoyile, aze akhangele ngokukhawuleza ukuba impendulo engaqhelekanga ifunyenwe. Xa i-gap yokuthwala iphezulu, i-gap yokuthwala kufuneka ilungiswe. Ukuba ayinakulungiswa, ukuthwala kunokutshintshwa kwaye kukhuhlwe. Xa i-cylindricity yejenali ye-crankshaft idlula kumda wenkonzo, ijenali ye-crankshaft kufuneka ipoliswe kwaye ukuthwala kufuneka kuphinde kukhethwe.
