Umhlangano wenduku yokuxhuma uhlanganiswe nomzimba wenduku yokuxhuma, ikhava yenduku yokuxhuma, ibhowodi yenduku yokuxhuma kanye nokuthwala induku yokuxhuma.

Iziphetho ezimbili zenduku yokuxhuma, isiphetho esincane ekugcineni kwesinye sisetshenziselwa ukufaka iphinikhodi yokuxhuma i-piston; umkhawulo owodwa uxhunywe kujenali yenduku yokuxhuma ye-crankshaft enomkhawulo omkhulu. Isihlahla sethusi sicindezelwa ekugcineni okuncane kwenduku yokuxhuma, efakwe emikhono ephinikhodi ye-piston. Kunegebe elithile ohlangothini lwekhanda elincane ukulivimbela ukuthi lingabambeki esihlalweni sembobo yephini phakathi nomsebenzi. Imbobo yokuqoqa uwoyela inamathiselwe ngaphezu komkhawulo omncane wenduku yokuxhuma kanye nesihlahla, futhi ixhumana ne-oil groove endaweni engaphakathi yehlathi. Lapho injini kadizili isebenza, uwoyela ochaphaziwe uwela emgodini ukuze ugcobe iphinikhodi ye-piston kanye nehlathi. I-bolt yenduku yokuxhuma iyibhawudi elikhethekile elisetshenziselwa ukuxhuma isembozo senduku yokuxhuma kanye nenduku yokuxhuma ibe yinye. I-bearing rod yokuxhuma ifakwe esihlalweni sembobo esisekupheleni kwenduku yokuxhuma, futhi ifakwe kanye nejenali yenduku yokuxhuma ku-crankshaft. Ingenye yamapheya abaluleke kakhulu afanayo enjinini.

Ukuthwala induku yokuxhuma kufakwe emgodini omkhulu wokugcina wenduku yokuxhuma. Kuyibheringi eslayidayo (inani elincane kuphela lamabheringi aginqikayo ezinjinini ezincane), ahlanganisa amathayili amabili ayindilinga, ngokuvamile abizwa ngokuthi i-bearing. Izinjini eziningi zesimanje zisebenzisa ama-bearings anezindonga ezincane. Isihlahla esithwalayo esinezindonga ezincane siwungqimba lwengxubevange enciphisa ukungqubuzana (0.3 ~ 0.8 mm) ephonswe ngemuva kwesihlahla sensimbi. I-bearing rod yokuxhuma ingavikela imbobo enkulu yokugcina yenduku yokuxhuma kanye nejenali yenduku yokuxhuma ye-crankshaft, ukuze induku yokuxhuma ne-crankshaft isetshenziswe isikhathi eside.

Ukuthwala induku yokuxhuma kufanele kushintshwe kusethi ephelele, futhi ubukhulu kufanele buhambisane nobukhulu bejenali yenduku yokuxhuma. Isihlahla esithwala induku yokuxhuma singashintshwa. Induku yokuxhuma nekhava yenduku yokuxhuma icutshungulwa ngamabhangqa, futhi ukushintshwa akuvunyelwe. Lapho ukhetha isihlahla esithwalayo, qala uhlole ukunwebeka kwethayela. Uma i-tile igxiliwe kukhava ye-tile, i-tile kanye nesembozo se-tile kumele kube nokuqina okuthile. Uma i-tile ingawa ngokukhululekile kukhava yethayili, i-tile ayikwazi ukuqhubeka Sebenzisa; ngemva kokuba ithayela licindezelwe kukhava yethayela, kufanele libe phezulu kancane kunendiza yekhava yethayela, ngokuvamile libe ngu-0.05 ~ 0. 10 mm.

I-bearing rod bearing iyingxenye esengozini, futhi izinga layo lokugqoka lithinteka kakhulu yikhwalithi yamafutha okugcoba, imvume efanelekile kanye nokuqina kwendawo yejenali. Izinga likawoyela liphansi, kukhona ukungcola okuningi, futhi igebe lokuzala lincane kakhulu, okulula ukubangela ukuthi isihlahla esithwalayo sishwabane noma sishise. Uma igebe likhulu kakhulu, ifilimu yamafutha akulula ukwenza, futhi ungqimba lwe-alloy oluthwala lujwayele ukuqhekeka kokukhathala noma ngisho ne-flake. Ngaphambi kokukhetha i-bearing rod yokuxhuma, igebe lokugcina lokuphela okukhulu kwenduku yokuxhuma kufanele lihlolwe. Kunegebe elithile phakathi kohlangothi lwesiphetho esikhulu senduku yokuxhuma kanye ne-crankshaft crank. Injini ejwayelekile ingu-0.17 ~ 0.35 mm, injini yedizili ingu-0.20 ~ 0.50 mm, uma idlula inani elishiwo, uhlangothi olukhulu lwesiphetho senduku yokuxhuma lungakhandwa.

Lapho ufaka i-bearing rod yokuxhuma, kufanele uqinisekise ukuthi ishintshwa ngokuvumelana nendawo yokuqala yokufaka, futhi akufanele ifakwe ngephutha. Amathayili nezihlalo zamathayela kufanele zihlanzeke futhi zifakwe ngokuqinile, futhi imvume ecacisiwe yokulingana phakathi kwephedi yokuthwala kanye nejenali kufanele kuqinisekiswe. Lapho uhlanganisa isihlahla esithwalayo, ukunakwa kufanele kukhokhwe ekuphakameni kwesihlahla esithwalayo. Uma ukuphakama kukhulu kakhulu, kungafakwa noma kupholishwe nge-sandpaper; uma ukuphakama kukuncane kakhulu, i-tile kufanele ihlelwe kabusha noma imbobo yokuhlala kufanele ilungiswe. Qaphela ukuthi kuvinjelwe ngokuqinile ukufaka ama-pads ngemuva kwe-tile ukwandisa isihlahla esithwalayo, ukuze ungaphazamisi ukuchithwa kokushisa futhi ubangele ukuthi isihlahla esithwalayo sikhululeke futhi sonakaliswe. Ukuthwala induku yokuxhuma kufanele kuhlanganiswe ngokuvumelana nenombolo ehambisanayo kanye nenombolo yokulandelana, futhi amantongomane nama-bolts kufanele aqiniswe ngokulinganayo ngokuvumelana ne-torque ecacisiwe. Udebe olubekayo lwenziwa esihlahleni esithwala induku yokuxhuma. Ngesikhathi sokufakwa, izindebe ezimbili zokuma zishunyekwa ngokulandelana emigodini ehambisanayo ekugcineni okukhulu kwenduku yokuxhuma kanye nesembozo senduku yokuxhuma ukuvimbela isihlahla esithwalayo ukuthi singazungezi futhi sinyakaze nge-axially.
