Isihlahla esithwala i-crankshaft.
Iithayile ezifakwe kwiibrakethi ezizinzileyo ze-crankshaft kunye ne-cylinder block kwaye zidlala indima yokuthwala kunye nokuthambisa zihlala zibizwa ngokuba zii-crankshaft bearing pads.
I-crankshaft bearing yahlulwe ngokubanzi ibe ziintlobo ezimbini: i-bearing kunye ne-flanging bearing. I-Flanged bearing shell ayinakuxhasa kwaye ithambise i-crankshaft kuphela, kodwa ikwadlala indima yokubeka i-axial ye-crankshaft.
inotshi
Izikhewu zeethayile ezimbini mazijonge kwicala elinye, kwaye ukuba isihlahla esithwala intonga yokudibanisa sikhethekile kumacala omabini, kufuneka kubonakale amanqaku kwicala lentonga yokudibanisa.
Ubude beebhering
Ibheriya entsha ifakwa kumngxuma wesihlalo, kwaye isiphelo ngasinye seziqwenga ezibini eziphezulu nezisezantsi kufuneka sibe phezulu nge-0.03-0.05mm kuneplani yesihlalo sebheriya. Ukuqinisekisa ukuba iqokobhe lebheriya kunye nomngxuma wesihlalo zihambelana kakuhle, phucula isiphumo sokusasaza ubushushu.
Indlela yokuvavanya ubude be-bearing bush yile: faka i-bearing bush, faka i-bearing bush cover, qinisa i-end bolt enye ngokwexabiso le-torque elichaziweyo, faka i-gasket enobukhulu obuyi-0.05mm phakathi kwesinye isigqubuthelo sesiphelo kunye ne-bearing bush seat plane, xa i-torque ye-screw end bolt ifikelela kwi-10-20N·m, ukuba i-gasket ayinakukhutshwa, ibonisa ukuba ubude be-bearing bude kakhulu, kwaye isiphelo ngaphandle kokubeka i-joint kufuneka sifakwe phantsi; Ukuba i-gasket ingakhutshwa, ibonisa ukuba ubude be-bearing buyafaneleka; Ukuba i-gasket ayifakwanga kwi-screw kwixabiso le-torque elichaziweyo, ayinakukhutshwa, nto leyo ebonisa ukuba i-bearing bush imfutshane kakhulu kwaye kufuneka ikhethwe kwakhona.
Umqolo othambileyo we-tenon ulungile
Umqolo weebheringi kufuneka ungabi nabala, uburhabaxa bomphezulu iRa yi-0.8μm, i-tenon inokuthintela ukujikeleza kwe-bearing bushing, umsebenzi wokubeka indawo, njengokuba i-tenon iphantsi kakhulu, ingasetyenziselwa ukuchaphazela ukuphakama okufanelekileyo, njengomonakalo we-tenon, kufuneka ikhethwe kwakhona i-bearing bushing.
Ilingana ne-elastic ngaphandle kwe-husk
Emva kokubeka isihlahla esitsha sokuthwala kwisihlalo sokuthwala, irediyasi egobileyo yesihlahla sokuthwala kufuneka ibe nkulu kunerediyasi egobileyo yomngxuma wesihlalo. Xa isihlahla sokuthwala sifakwe kumngxuma wesihlalo, sinokufakwa ngokusondeleyo kumngxuma wesihlalo sokuthwala ngasentwasahlobo yesihlahla sokuthwala ukuze kube lula ukusasazwa kobushushu. Jonga ukuba igobolondo lokuthwala alinamsebenzi na, ungacofa ngasemva kwegobolondo lokuthwala ukuze ujonge, kukho isandi esingenamsebenzi esibonisa ukuba i-alloy kunye nepleyiti esezantsi azinamandla, kufuneka zikhethwe kwakhona.
Umsantsa ohambelanayo wejenali yethayile yeshaft kufuneka ulungele
Xa kukhethwe iqokobhe lebheriya, kufuneka kujongwe umsantsa ohambelanayo. Ngexesha lokuhlolwa, i-cylinder gauge kunye ne-micrometer zilinganisa i-bearing bush kunye nejenali, kwaye umahluko kukungena kwe-fit clearance. Indlela yokuhlola yokususwa kwe-bearing bush yile: kwi-connecting rod, faka umaleko omncinci weoyile kwi-bearing bush, qinisa intonga yokudibanisa kwijenali ehambelanayo, qinisa i-bolt ngokwexabiso le-torque elichaziweyo, uze ujike intonga yokudibanisa ngesandla, ungajikelezisa i-1 ~ 1/2 turns, tsala intonga yokudibanisa kwicala le-axis, akukho mvakalelo ye-gap, oko kukuthi, ukuhlangabezana neemfuno; Kwi-crankshaft shingles, faka ioyile kumphezulu wentamo nganye ye-shaft kunye ne-bearing shingles, faka i-crankshaft kwaye uqinise ii-bolts ngokwexabiso le-torque elichaziweyo, kwaye utsale i-crankshaft ngezandla zombini, ukuze i-crankshaft ikwazi ukujika i-1/2 turns, kwaye ukujikeleza kube lula kwaye kufane ngaphandle kokuthintela into.
Indlela efanelekileyo yokufaka ithayile ye-crankshaft
Ukufakelwa ngokufanelekileyo kweethayile ze-crankshaft kuquka la manyathelo abalulekileyo alandelayo:
Ukufakelwa kwe-balance shaft: Faka i-balance shaft kwicala ngalinye le-crankshaft. Ezi -balance shafts zixhomekeke kwi-splashing oil ukuze zithambise, endaweni yokuthambisa ngenkani ngepompo yeoyile. Ke ngoko, ulawulo lwesithuba phakathi kwe-balance shaft kunye ne-bearing shell lubaluleke kakhulu kwaye kufuneka lugcinwe phakathi kwe-0.15-0.20 mm.
Ulawulo lwezithuba kunye nokulungiswa kwazo: Ukuba akukho lula ukuzilawula, ungasebenzisa i-feeler kuqala ukulinganisa isithuba esiphakathi kwe-bearing bush kunye ne-balance shaft xa i-bearing bush ingafakwanga kwi-cylinder block. Isithuba esicetyiswayo yi-0.3 mm. Ukuba isithuba singaphantsi kwe-0.3 mm, ubungakanani obufunekayo bunokufezekiswa ngokukrwela okanye ngomatshini kwi-lathe ukuqinisekisa ukuba umgangatho wokuphazamiseka phakathi kwe-bearing bush kunye nomngxuma we-bearing yi-0.05 mm, kwaye isithuba simalunga ne-0.18 mm emva kokuba i-bearing bush icinezelwe kumngxuma we-bearing.
Isihlahla esiqinileyo sokuthwala: Xa ufaka isihlahla esilinganayo sokuthwala, kufuneka ufake iglu ye-302AB ngasemva kwesihlahla esithwalayo ukuze uqinise uzinzo lwesihlahla esithwalayo kwaye usithintele ekushukumeni okanye ekukhululekeni.
Indawo yokubeka iibheringi kunye nokuthambisa: iqokobhe ngalinye lokubeka iibheringi lineqhuma elibekwe kwindawo, ekufuneka lifakwe kwindawo yokubeka iibheringi kwibhloko yesilinda. Kwangaxeshanye, qinisekisa ukuba umngxuma wokudlula ioli kwibheringi uhambelana nendawo yokubeka iibheringi kwibhloko yesilinda ukuze kusekwe inkqubo yokuthambisa.
Ukufakelwa kwesiciko sebheri: Emva kokufaka isigqubuthelo sokuqala sebheri, jika i-crankshaft ukuqinisekisa ukuba akukho nto ibambekileyo. Faka isigqubuthelo sebheri kwaye usiqinise ngokwemigaqo. Oku kwenziwa kwisigqubuthelo ngasinye sebheri. Ukuba isigqubuthelo sebheri sibambekile, ingxaki isenokuba kwisiciko sebheri okanye kwinxalenye yebheri. Susa kwaye ujonge ukuba akukho burrs okanye ukulingana okungafanelekanga kwesihlalo sebheri.
Ngokulandela la manyathelo, unokuqinisekisa ukufakwa ngokufanelekileyo kweethayile ze-crankshaft kwaye uphephe ukungaphumeleli koomatshini ngenxa yokufakwa okungafanelekanga.
