Yintoni equlethwe yi-piston assembly?
Indibano yepiston yinxalenye ebalulekileyo yenjini yemoto, equlathe ikakhulu ezi zinto zintandathu zilandelayo:
1. Ipiston: Iyinxalenye yegumbi lokutsha kwaye ixhotyiswe ngemijelo emininzi yeringi yokufaka iringi yepiston.
2. Indandatho yepiston: Ifakwe kwipiston ukuze itywinwe, idla ngokwenziwa ngendandatho yegesi kunye nendandatho yeoyile.
3. Iphini yepiston: Ukudibanisa ipiston kunye nentloko encinci yentonga yokudibanisa ipiston, kukho iindlela ezimbini zokudada ngokupheleleyo kunye nokudada kancinci.
4. Intonga yokudibanisa iPiston: intonga yokudibanisa yePiston kunye neCrankshaft, yahlulwe yaba yintloko enkulu kunye nentloko encinci kumacala omabini, intloko encinci iqhagamshelwe kwiPiston, intloko enkulu iqhagamshelwe kwiCrankshaft.
5. I-Connecting rod bearing: i-lubricating component efakwe kwintloko enkulu ye-connecting rod.
6. Ibholithi yentonga yokudibanisa: ibholithi ebopha isiphelo esikhulu sentonga yokudibanisa kwi-crankshaft.
Indandatho yepiston yinxalenye ephambili ngaphakathi kwenjini yepetroli, yona kunye nesilinda, ipiston, udonga lwesilinda kunye ukuze kugqitywe ukuvalwa kwegesi yepetroli. Iinjini zeemoto ezisetyenziswa rhoqo zineentlobo ezimbini zeenjini zedizili kunye nepetroli, ngenxa yokusebenza kwazo okwahlukileyo kwepetroli, ukusetyenziswa kwendandatho yepiston akufani, indandatho yepiston yokuqala yenziwa ngokuphosa, kodwa ngenkqubela phambili yetekhnoloji, indandatho yepiston enamandla aphezulu yazalwa, kwaye ngomsebenzi wenjini, iimfuno zokusingqongileyo ziyaqhubeka nokuphucula, iintlobo ngeentlobo zezicelo zonyango lomphezulu ophezulu, ezifana nokutshiza ngobushushu, ukufakelwa kwe-electroplating, ukufakwa kwe-chrome, njl. I-nitriding yegesi, ukufakwa komzimba, ukugqunywa komphezulu, unyango lwe-zinc manganese phosphating, njl., kuphucula kakhulu umsebenzi wendandatho yepiston.
Iphini yepiston isetyenziselwa ukudibanisa ipiston kwintonga yokudibanisa kunye nokudlulisela amandla kwipiston kwintonga yokudibanisa okanye ngokuchaseneyo.
Iphini yepiston iphantsi komthwalo omkhulu wempembelelo phantsi kweemeko zobushushu obuphezulu, kwaye ngenxa yokuba i-Angle ye-swing yephini yepiston emngxunyeni wephini ayinkulu, kunzima ukwenza ifilimu yokuthambisa, ngoko ke imeko yokuthambisa ayilunganga. Ngenxa yesi sizathu, iphini yepiston kufuneka ibe nokuqina okwaneleyo, amandla kunye nokumelana nokuguguleka. Ubunzima buncinci kangangoko kunokwenzeka, kwaye iphini kunye nomngxunya wephini kufuneka zibe nezikhewu ezifanelekileyo kunye nomgangatho olungileyo womphezulu. Ngokubanzi, ukuqina kwephini yepiston kubaluleke kakhulu, ukuba ukuguqulwa kwephini yepiston, kunokubangela umonakalo kwisihlalo sephini yepiston.
Ngamafutshane, imeko yokusebenza kwepiston pin kukuba umlinganiselo woxinzelelo mkhulu, ifilimu yeoyile ayinakwenzeka, kwaye ukuguqulwa kwayo akuhambelani. Ke ngoko, uyilo lwayo lufuna amandla aphezulu oomatshini kunye nokumelana nokuguguleka, kodwa kunye namandla aphezulu okudinwa.
Umzimba wentonga yokudibanisa wenziwe ngamacandelo amathathu, kwaye inxalenye edibene nephini yepiston ibizwa ngokuba yintloko encinci yentonga yokudibanisa; Inxalenye edibene ne-crankshaft ibizwa ngokuba yintloko enkulu yentonga yokudibanisa, kwaye inxalenye edibanisa intloko encinci kunye nentloko enkulu ibizwa ngokuba yi-body yentonga yokudibanisa.
Ukuze kuncitshiswe ukuguguleka phakathi kwentloko encinci kunye nephini yepiston, ibhushi yobhedu enodonga oluncinci icinezelwa kumngxuma omncinci wentloko. Ukubhoboza okanye ukugawula iigrooves kwiintloko ezincinci kunye neebhushi ukuvumela ukutshiza kweoyile ukuba kungene kumphezulu wokudibana kwephini yepini yepiston yokuthambisa.
Umzimba wentonga yokudibanisa yinduku ende, kwaye amandla asebenzayo nawo makhulu, ukuze kuthintelwe ukuguquka kwayo, umzimba wentonga kufuneka ube nokuqina okwaneleyo. Ngenxa yesi sizathu, umzimba wentonga yokudibanisa yenjini yesithuthi ikakhulu usebenzisa icandelo lesimo soku-1, elinokunciphisa ubunzima phantsi kwemeko yokuba ukuqina namandla anele, kwaye injini enamandla aphezulu inecandelo elimile okwe-H. Ezinye iinjini zisebenzisa i-piston yokupholisa i-oyile yentsimbi encinci, ekufuneka igqojwe ngomngxuma omde emzimbeni wentonga. Ukuze kuthintelwe uxinzelelo loxinzelelo, umzimba wentonga yokudibanisa, intloko encinci kunye nentloko enkulu ziqhagamshelwe ngenguqu enkulu egudileyo ejikelezayo.
Ukuze kuncitshiswe ukungcangcazela kwenjini, umahluko womgangatho wentonga yokudibanisa yesilinda kufuneka ulinganiselwe kuluhlu oluncinci, kwindibano yefektri yenjini, ngokubanzi kwiigram njengeyunithi yokulinganisa ngokwesisindo esikhulu nesincinci sentonga yokudibanisa, injini efanayo yokukhetha iqela elifanayo lentonga yokudibanisa.
Kwinjini yohlobo lwe-V, ii-cylinders ezihambelanayo kwiikholamu zasekhohlo nasekunene zabelana nge-crank pin, kwaye intonga yokudibanisa ineentlobo ezintathu: intonga yokudibanisa ehambelanayo, intonga yokudibanisa yefolokhwe kunye nentonga yokudibanisa ephambili nencedisayo.
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 (Umfanekiso 1) kunye ne-flanged bearing (Umfanekiso 2). I-Flanged bearing bushing ayinakuxhasa kwaye ithambise i-crankshaft kuphela, kodwa ikwadlala indima ye-axial positioning ye-crankshaft (kunokubakho indawo enye kuphela kwi-crankshaft yokuseta isixhobo se-axial positioning).
Xa sisebenzisa iibholiti zentonga yokudibanisa, siya kufumanisa ukuba kukho iingxaki ezininzi ngeebholiti zentonga yokudibanisa, kuya kubakho iingxaki zembonakalo, iingxaki zobude bokunyamezelana, iingxaki zokuqhekeka, iingxaki zentambo yamazinyo, iingxaki ezifumaneka ngexesha lokufakwa, njalo njalo.
Indlela elula kukuvavanya i-connecting rod bolt, ufumanise apho ingxaki ikhoyo kwaye uyitshintshe. Uvavanyo lwe-connecting rod bolt lufuna indlela. I-connecting rod bolt yi-bolt ebalulekileyo edibanisa isihlalo se-bearing sesiphelo esikhulu sentonga yokudibanisa kunye nesigqubuthelo se-bearing. I-connecting rod bolt iphantsi kwesenzo samandla okulayisha kwangaphambili ngexesha lokuhlanganiswa, kwaye i-connecting rod bolt iphantsi kwesenzo samandla e-inertia xa injini yedizili ye-stroke ezine isebenza. Ububanzi be-connecting rod bolt buncinci kuba bunqunyelwe bububanzi be-crank pin kunye nobukhulu be-veranda yangaphandle yesiphelo esikhulu sentonga yokudibanisa.
Ibholiti edibanisa isigqubuthelo sentonga yokudibanisa esahluliweyo kwisiphelo esikhulu sentonga yokudibanisa. Kwisibini ngasinye seebheringi, iibholiti ezimbini okanye ezine zentonga yokudibanisa zihlala zisetyenziswa ukuziqinisa. Uhlobo lwebholiti luyahluka. Intloko idla ngokwenziwa ngomatshini ngeplani yokuma okanye ibhloko engqukuva yokufakelwa kunye nokuxhonywa nomphezulu wenkxaso yebheri ukuthintela ibholiti yentonga yokudibanisa ukuba ingajikelezi xa iqiniswa i-nut. Ububanzi bomzimba wentonga yebholiti kumphezulu ngamnye wecandelo lebheriti bukhulu, ukuze ibekwe nomngxuma webholiti ngexesha lokuhlanganiswa; Ububanzi benxalenye eseleyo yomzimba wentonga yebholiti buncinci kunobubanzi bomngxuma webholiti, kwaye ubude bude, ukuze umthwalo wenxalenye yentambo uncitshiswe xa umthwalo wokugoba kunye nowokuchaphazeleka uthwalwa. Inxalenye yentambo idla ngokusebenzisa umsonto omncinci ngokuchanekileyo okuphezulu.
Ukuze kuthintelwe uqhagamshelo olunemisonto ukuba lungazikhululeki, i-bolt yentonga edibanisayo inesixhobo esihlala sisebenza ngokuchasene nokungakhululeki, esidla ngokuba yi-cotter pin, i-washer ethintela ukukhululeka kunye ne-copper plating kumphezulu wentambo. Ii-bolt zentonga ezidibanisayo zihlala zithwala imithwalo etshintshanayo, elula ukubangela umonakalo nokudinwa, nto leyo eya kubangela iziphumo ezibi kakhulu. Ke ngoko, idla ngokwenziwa ngentsimbi ye-alloy ekumgangatho ophezulu okanye intsimbi yekhabhoni ekumgangatho ophezulu, kwaye emva kokulungiswa kobushushu. Kulawulo, kufuneka kuqwalaselwe ukujonga ukuqina kwayo ukuze kuthintelwe ukukhululeka; Ukuyiqhaqha rhoqo kujongwe ukuba ayinamaqhekeza kunye nobude obugqithisileyo, njl.njl., kufuneka itshintshwe ngexesha ukuba kuyimfuneko. Xa uyifaka, kuyimfuneko ukunqumla kunye nokuqinisa kancinci kancinci ngokwendlela emiselweyo yokuqinisa kwangaphambili, engenakuba nkulu kakhulu okanye incinci kakhulu, ukuze kuthintelwe iingozi ezifana nokuqhekeka kwe-bolt yentonga emsebenzini.
