Iyo axial clearance ye crankshaft inonziwo kuguma kubviswa kwe crankshaft. Mukushanda kweinjini, kana gap iri diki, zvikamu zvichange zvakanamira nekuda kwekuwedzera kwekupisa; kana gaka racho rakanyanya kukura, crankshaft ichakonzera axial kufamba, kukurumidza kupfeka kwecylinder, uye inokanganisa kushanda kwakajairika kwechikamu chevhavha uye clutch. Kana injini ichiwedzerwa, ukuru hwegomba iri hunofanira kuongororwa uye kugadziriswa kusvikira yakakodzera.

Kuyerwa kwe crankshaft clearance kunosanganisira axial clearance kuyerwa uye main bearing radial clearance kuyerwa.

(1) Kuyera kweaxial clearance ye crankshaft. Ukobvu hweplate inorovera kumucheto kumashure kwe crankshaft inosarudza axial clearance ye crankshaft. Pakuyera, isa chiratidzo chedhiya kumucheto kumberi kweinjini crankshaft, gogodza crankshaft kuti uidzorere kumashure kune inogumira chinzvimbo, wozorongedza chiratidzo chedhiya kune zero; wobva wafambisa crankshaft kumberi kune inogumira chinzvimbo, ipapo dial chiratidzo Chiratidzo cheiyo axial clearance ye crankshaft. Inogonawo kuyerwa negeji yekunzwa; shandisa mascrewdriver maviri kuti uise pakati pechimwe chivharo chikuru chinotakura chivharo uye ruoko runoenderana ne crankshaft, uye mushure mekunangisa crankshaft kumberi kana kumashure kune inogumira chinzvimbo, isa inofefetera geji mubere rechinomwe. , gap iri ndiro gwanza reaxial re crankshaft. Zvinoenderana nemirairo yekutanga fekitori, chiyero cheaxial clearance ye crankshaft yemota iyi ndeye 0.105-0.308mm, uye muganho wekupfeka ndeye 0.38mm.

(2) Radial clearance kuyerwa kwekutakura kukuru. Kubvumidzwa pakati pejenari huru ye crankshaft uye iyo huru inotakura ndeye radial clearance. Pakuyera, isa chiyero chepurasitiki chewaya (plastic gap gauge) pakati pejenari guru nebearingiro guru, uye chenjerera kuti usatenderedza crankshaft kudzivirira gap kubva pakushanduka panguva yekutenderera uye kuruma geji yegeji. Kuchenjerera kunofanira kubhadharwa kune pesvedzero yemhando ye crankshaft pane clearance.
