Umsebenzi we-crankshaft kukuguqula uxinzelelo lwegesi ukusuka kwiqela le-piston lokudibanisa intonga kwi-torque yemveliso yangaphandle, kunye nokuqhuba isitimela sevalve kunye nezinye izixhobo ezincedisayo. Uninzi lwazo lwenziwe ngentsimbi yekhabhoni ekumgangatho ophakathi, intsimbi ephakathi kwealloy okanye i-spheroidal graphite cast iron. Ubume be-crankshaft bubandakanya i-shaft yangaphambili, ijenali ephambili, ijenali yentonga yokudibanisa, i-crank, i-counterweight, i-shaft yangasemva, njl. . Ijenali. Ngenxa yokuba iya kuba phantsi kwemikhosi eyahlukeneyo esetyenziswayo, kuya kubakho umlinganiselo othile wokunxiba, kwaye iindawo ezahlukeneyo zineempawu ezahlukeneyo zokunxiba.
Nxiba iimpawu zejenali ephambili kunye nesihlahla esithwalayo
Ukunxitywa kwejenali ephambili ecaleni kwendlela ye-axial kufuneka ifane, kwaye inani lokunxiba kwicala le-radial alilingani, kwaye kuya kubakho i-ellipticity encinci. Kuba ijenali ephakathi ihlala iphantsi kwamandla amakhulu, isixa esinxitywayo sihlala sisikhulu kuneso seziphelo zombini. I-radial wear of the main bearing bush ihambelana nejenali ephambili. Inxalenye enkulu yokunxiba ikwi-bearing ephantsi, kwaye ukunxiba kwesihlahla esiphakathi esithweleyo kukhulu kunoko kweziphelo zombini.
Gqoka iimpawu zejenali yokudibanisa intonga kunye ne-rod bush yokudibanisa
Ukunxiba kweradial yeejenali zentonga yokudibanisa kunye neebheringi azilingani, kwaye ukunxiba kwicala langaphakathi kukhulu. Ukunxiba okungalinganiyo kubangela ukuba ijenali yentonga yokudibanisa yenze i-ellipse ethile kwicala le-radial, kwaye ulwalathiso lwe-axial ngokubanzi lufana. Intonga yokudibanisa ene-asymmetric enkulu-end structure iya kuba yi-tapered emva kokugqoka ngenxa yokuhanjiswa komthwalo ongalinganiyo kwijenali yokudibanisa intonga; intonga yokudibanisa ene-symmetrical enkulu-end structure iya kubangela iziphumo ezifanayo ukuba igobile.
Elona candelo linxitywa kakhulu kwijenali yokudibanisa intonga ngokuqhelekileyo kwicala langaphakathi kwijenali nganye, oko kukuthi, kwicala le-crankshaft centerline, ukuze ijenali iphume kumjikelo; kwaye indawo enxiba ikhowuni iba kwicala lepaseji yeoli yokuthambisa apho kuncanyathiselwe ukungcola. Ecaleni kunye nendawo apho amandla amakhulu.
Ukunxiba kwe-crankshaft kunokulinganiswa nge-micrometer. Ukunxitywa kwejenali emfutshane ye-crankshaft kufuneka ihlolwe ubukhulu becala kujongwe iimpazamo ezingqukuva, kwaye kwiijenali ezinde, iimpazamo ezingqukuva kunye ne-cylindricity kufuneka zihlolwe. Indlela ethile yokulinganisa yile: thatha amacandelo amabini kwijenali nganye, kwaye uthathe amanqaku amabini kwicandelo ngalinye. Isiqingatha somahluko phakathi kobukhulu obukhulu kunye nobukhulu obuncinci bedayamitha yecandelo elifanayo yimpazamo yokujikeleza; isiqingatha somahluko phakathi kobukhulu obukhulu kunye nobukhulu obuncinci kumacandelo amabini yimpazamo ye-cylindricity. Phantsi kweemeko eziqhelekileyo zokusebenza, ukunxiba kwe-crankshaft kuncinci kakhulu, akubi ngaphezu kwe-0.01mm ngokubanzi, kwaye isilinda singaphantsi kwe-0.0025mm.
Iindlela eziqhelekileyo zomonakalo we-crankshaft ziquka ukugqokwa kwejenali, ukuqhekeka, ukutshisa, ukugoba okanye ukuphuka, njl. Umzekelo, ubungakanani bokunxitywa kwe-crankshaft bukhulu kakhulu, kwaye i-bearing bush ide ivuze umbala ongasemva. Le meko idla ngokubangelwa kukuthanjiswa okulambathayo, uxinzelelo lwe-oyile ephantsi, kunye ne-oyile engazifikeleliyo iimfuno zokusetyenziswa. I-Crankshaft cylinder inkulu kakhulu, nto leyo ebonisa ukuba injini ibisebenza phantsi komthwalo onzima ixesha elide. ; I-crankshaft iyatshisa, i-blues, i-locks, kufuneka ibangelwa yi-lubrication engafanelekanga, eyona nto ixhaphakileyo kukungabikho kweoli.
