Crankshaft, yaba moteri yimodoka, crankshaft ya moteri yo mumazi cyangwa pompe yinganda, ikorerwa ibikorwa bihujwe no guhinduranya no guhinduranya imitwaro ya torsional mugihe cyo kuzunguruka. Ibice biteye akaga bya crankshaft, cyane cyane inzibacyuho yuzuye hagati yikinyamakuru na crankshaft. Kuri ubu, igikonjo gikunze kuvunika kubera guhangayikishwa cyane. Kubwibyo, imiterere ya serivise isaba igikonjo kugira imbaraga zihagije kugirango tumenye neza ko igikona kitavunika mugihe gikora. Kugeza ubu, guhindura umunaniro ukabije wa crankshaft ukoresheje kurasa byakoreshejwe henshi, kandi ingaruka zirashimishije.

Ugereranije nubusembwa bwibikorwa gakondo bizunguruka, ni ukuvuga, kubera kugabanuka kwikoranabuhanga ryo gutunganya crankshaft, impande zegeranye za buri kinyamakuru biragoye guhuza ibizingo, akenshi bitera ibintu byo guhekenya no guca inguni zegeranye, na crankshaft nyuma yo kuzunguruka ihinduwe cyane. , ntabwo ari byiza. Uburyo bwo kurasa ni ugukoresha ibice byamasasu bifite diameter igenzurwa cyane nimbaraga runaka. Mubikorwa byumuvuduko mwinshi wumuyaga, urujya n'uruza rwamasasu rugahora ruterwa hejuru yicyuma hejuru yigitereko, kimwe ninyundo hamwe ninyundo ntoya zitabarika, kuburyo hejuru yigitereko inyundo. Yibyara plastike ikomeye cyane, ikora imirimo ikonje ikomera. Mumagambo yoroshye, kubera ko igikonjo gikoreshwa ningufu zitandukanye zo gukata imashini mugihe cyo gutunganya, gukwirakwiza impagarara hejuru yacyo, cyane cyane kumyuzure yinzibacyuho yibice bya crankshaft, ntibingana cyane, kandi bigaterwa no guhinduranya imbaraga mugihe cyakazi, bityo biroroshye Stress ruswa ibaho kandi ubuzima bwumunaniro wa crankshaft buragabanuka. Igikorwa cyo kurasa ni ugukuraho impungenge zikomeye zerekana ko ibice bizakorerwa mugihe cyakazi gikurikiraho mugutangiza imihangayiko mbere yo kwikuramo, bityo bikazamura umunaniro ukabije hamwe nubuzima bwiza bwakazi bwakazi.

Byongeye kandi, crankshaft yo guhimba imyenda ikozwe muburyo butaziguye cyangwa bikozwe mubyuma bishyushye. Niba guhimba no kuzunguruka bitagenzuwe neza, akenshi hazabaho gutandukanya ibice mubutaka, ibinyampeke bito byububiko bwambere, no gukwirakwiza bidafite ishingiro imbere. nizindi nenge za metallurgiki nu muteguro, bityo bikagabanya ubuzima bwumunaniro wa crankshaft, kandi inzira yo gushimangira irashobora kunonosora imiterere yubuyobozi kandi igateza imbere imikorere yumunaniro.
