Yintoni ibheyaringi yentonga yokudibanisa imoto?
I-crankshaft pin (eyaziwa ngokuba yi-"small pin") yinxalenye ebalulekileyo ye-sliding bearing kwi-injini. Ifakwe phakathi kwesiphelo esikhulu sentonga yokudibanisa kunye ne-crankshaft connecting rod journal, inceda ukudibanisa i-piston, i-connecting rod kunye ne-crankshaft, kwaye iququzelela ukuhanjiswa kwamandla kunye nokuguqulwa kwentshukumo. Umsebenzi ongundoqo
Nciphisa ukungqubana: Ngokusebenzisa izixhobo ezikwaziyo ukumelana nokugcinwa kakuhle, ukungqubana okutyibilikayo phakathi kwentonga yokudibanisa kunye ne-crankshaft kuyancitshiswa.
Inkxaso kunye nokubekwa kwayo: Qinisekisa ukuba intonga yokudibanisa ijikeleza ngokuzinzileyo kwi-crankshaft ngexesha lokushukuma kwesantya esiphezulu.
Ukusasazwa kobushushu: Dlulisa ubushushu obuveliswa kukungqubana kwintloko enkulu yentonga yokudibanisa ukuthintela ubushushu obugqithisileyo bendawo.
Ubonelelo lwepetroli kunye nokuthambisa: Ezinye iijenali zentonga yokudibanisa zenzelwe imingxunya yeoyile kunye nemingxunya yeoyile, enika ioyile eludongeni olungaphakathi lwepiston ukuze ipholise ipiston.
Iimpawu zesakhiwo
Ukwakhiwa kwezinto: Ngokwesiqhelo zenziwe ngomqolo wentsimbi + umaleko we-alloy onciphisa ukuguguleka (njenge-alloy yeBabbitt, i-alloy ephezulu esekelwe kwi-tin-aluminium, i-bronze ye-lead, njl.njl.).
Ubukhulu: Umqolo wentsimbi umalunga ne-1–3mm, kwaye umaleko onciphisa ukuguguleka umalunga ne-0.3–0.7mm.
Uyilo oluhlukanisiweyo: Lwahlulwe lwaba ziijenali eziphezulu nezisezantsi, kwaye isikhokelo sokufakelwa kunye nokumakishwa kufuneka kuqatshelwe ngexesha lokufakwa.
Ulwakhiwo lwendawo: Kukho iindawo ezibonakala ngathi zibekwe okanye zinotshi ukuze kuthintelwe ukujikeleza okanye ukufakwa okungafanelekanga.
Amagama aqhelekileyo kunye neendlela ezahlukileyo
"Ijenali encinci": Ibizwa ngokuba yijenali yentonga yokudibanisa incinci kunejenali ephambili ("ijenali enkulu"), kwaye incinci ngobukhulu.
Umahluko kwijenali ephambili:
Ijenali ephambili (ijenali enkulu): Ixhasa ijenali ye-crankshaft kwaye inamathele kwibhloko yesilinda. Isakhiwo sihlala sinemingxuma yeoyile kunye nee-grooves zokubonelela ngeoyile, ezisetyenziselwa inkxaso ezinzileyo.
Ijenali yentonga yokudibanisa (ijenali encinci): Ilandela ukujijeka okubuyelanayo kwentonga yokudibanisa, kunye nesakhiwo esilula. Ezinye iinjini ezikhawulezayo zinesigqubuthelo sokuphucula ukumelana nokuguguleka.
Iimpawu zempazamo
Ukuphuma okugqithisileyo: Uxinzelelo lweoyile oluphantsi kunye nesandi "sokungqongqoza kwesilinda".
Ukungavuleki kakuhle: Ukuguguleka okukhawulezileyo, kwaye kwiimeko ezinzima, kunokubangela "ukutshixwa kwe-crankshaft".
Ingxolo engaqhelekanga: Ingxaki yejenali yentonga yokudibanisa ibonakaliswa kakhulu njengesandi esicacileyo "sokuthepha", ngakumbi xa kukhawuleziswa ngequbuliso.
Iingcebiso zolondolozo
Xa kutshintshwa iijenali zentonga yokudibanisa, kuyimfuneko ukusebenzisa iinkcukacha zokuqala okanye ezifanayo zeejenali zokwenyani.
Ukufakelwa kufuneka kulandele ngokungqongqo iimfuno ze-torque ukuze kuqiniswe iibholiti zentonga yokudibanisa, kwaye kuqinisekiswe iinkcukacha zokuhlanganiswa ezifana necala lejenali, uphawu, kunye necala le-piston eliya kwigiya yexesha.
Ngexesha lokugcinwa kwemihla ngemihla, qwalasela umgangatho weoyile kunye nomjikelo wokutshintshwa kwayo, njengoko ioyile engeyongozi iya kukhawulezisa ukuguguleka kwejenali.
Iijenali zentonga yokudibanisa iimoto (ezaziwa ngokuba "ziijenali ezincinci") zizinto ezibalulekileyo zokuthwala izinto ezityibilikayo kwinjini, ezifakwe phakathi kwentloko enkulu yentonga yokudibanisa kunye nejenali ye-crankshaft. Imisebenzi yazo ephambili ingashwankathelwa ngolu hlobo lulandelayo:
Nciphisa ukungqubana kunye nokuguga: Ngokusebenzisa umaleko we-alloy onciphisa ukuguguleka (njenge-alloy emhlophe, i-alloy esekelwe kwi-aluminium, njl.njl.), ukungqubana ngqo phakathi kwentloko enkulu yentonga yokudibanisa kunye nejenali ye-crankshaft kuyancitshiswa, okukhusela zombini ekugugulekeni okugqithisileyo.
Inkxaso kunye nokubekwa kwayo: Njengebheri etyibilikayo, ixhasa ijenali ye-crankshaft, iqinisekisa unxibelelwano oluzinzileyo phakathi kwentonga yokudibanisa kunye ne-crankshaft, igcina indlela echanekileyo yokuhamba.
Amandla okudlulisa: Idlulisela uxinzelelo lwegesi kunye namandla okubuyisela amandla aphantsi athwalwa yipiston ukuya kwi-crankshaft, ifezekisa utshintsho ukusuka kwintshukumo ethe ngqo yepiston ukuya kwintshukumo yokujikeleza ye-crankshaft.
Ukuthambisa kunye nokusasaza ubushushu:
Iimbobo zeoyile kunye nemingxunya yeoyile kwijenali zichaza ngokuchanekileyo ioyile, zenze ifilimu yeoyile ezinzileyo, ifezekisa ukuthambisa;
Umqolo obhityileyo wentsimbi uqhuba ubushushu obubangelwa kukungqubana ukuya entlokweni enkulu yentonga yokudibanisa, unceda ekuchitheni ubushushu, uthintele ubushushu obugqithisileyo bendawo.
Yandisa ubomi benkonzo: Ngokusebenzisa uyilo olumelana nokuguguleka kunye nokuhlanganiswa okufanelekileyo, nciphisa ukuguguleka kwejenali, kwaye uphucule ukuqina kwenjini iyonke.
Iijenali zentonga ezidibanisayo zihlala zahlulwe zibe ziijenali eziphezulu nezisezantsi. Ijenali ephezulu ineemiqolo yeoyile kunye nemingxuma yeoyile yokuhambisa ioyile kwi-piston yangaphakathi ukuze iphole; ijenali esezantsi ayinamiqolo yeoyile kwaye ikakhulu ithatha indima yokuxhasa. Ngexesha lokufakela, nikela ingqalelo kwicala leeprotrusions zokubeka kunye nemigangatho ye-torque, kungenjalo, inokubangela ingxolo engaqhelekanga, ukutsha kwejenali, okanye nokutshixa kwe-crankshaft.
