Nzira dzekugadzirisa Crankshaft uye zvinodiwa zveinjiniya cranes: iyo radial runout ye crankshaft uye radial runout yechiso chekukanda pane yakajairwa axis yejenari huru inofanirwa kusangana nezvinodiwa zvehunyanzvi. Zvikasadaro, inofanira kugadziriswa. Tarisa kuomarara kunodiwa kwe crankshaft majenari uye yekubatanidza tsvimbo magazini, iyo inofanirwa kusangana nehunyanzvi zvinodiwa. Zvikasadaro, inofanira kudzokororwa kuti isangane nezvinodiwa zvekushandisa. Kana iyo crankshaft balance weight bolt yakatsemuka, inofanira kutsiviwa. Mushure mekunge crankshaft yatsiva bhaudhi yebhavhari kana bhaudhi block bolt, yave nguva yekuita chiyero chesimba bvunzo pamusangano we crankshaft kuona kuti huwandu husina kuenzana hunosangana nezvinodiwa zvehunyanzvi. Kupfeka-resistant electrode.

(1) Disassemble uye chenesa zvinhu zve crankshaft kuti uve nechokwadi chekuti mukati memafuta emukati me crankshaft yakachena uye isina kuvharika.

(2) Ita kuona kukanganisa pane crankshaft. Kana pakatsemuka, inofanira kutsiviwa. Nyatsotarisa crankshaft main jenari, yekubatanidza rod jenari neshanduko yayo arc, uye zvese zviri pamusoro hazvifanirwe kunge zvisina makwara, kutsva uye mapundu.

(3) Tarisa crankshaft main journal uye yekubatanidza tsvimbo jenari, wozvigadzirisa zvinoenderana nedanho rekugadzirisa mushure mekunge saizi yadarika muganhu. Iyo crankshaft journal repair yakaita seinotevera:

(4) Tarisa kuoma kunodiwa kwe crankshaft jenari uye yekubatanidza tsvimbo majenari, uye anofanirwa kusangana nehunyanzvi zvinodiwa. Zvikasadaro, inofanira kudzokororwa kuti isangane nezvinodiwa zvekushandisa.

(5) Radial runout ye crankshaft uye radial runout yekusundidzira kumeso kune yakajairwa axis yejenari huru inofanira kusangana nehunyanzvi zvinodiwa. Zvikasadaro, inofanira kugadziriswa.

(6) Kuenderana kweiyo yekubatanidza tsvimbo yejenari axis kune yakajairwa axis yejenari huru inofanirwa kusangana nezvinodiwa zvehunyanzvi.

(7) Kana kumberi nekumashure magiya ekutapurirana kwe crankshaft akatsemuka, kukuvara kana kupfekwa zvakanyanya, crankshaft inofanira kutsiviwa.

(8) Kana iyo crankshaft chiyero uremu bhaudhi yakatsemuka, inofanira kutsiviwa. Mushure mekunge crankshaft yatsiva huremu hwehuremu kana huremu huremu bhaudhi, yave nguva yekuita chiyero chesimba bvunzo pamusangano we crankshaft kuona kuti huwandu husina kuenzana hunosangana nezvinodiwa zvehunyanzvi. Kupfeka-resistant electrode

(10) Nyatsoongorora chibatiso chekuvhundutsa chetsoka ye crankcase. Kana yakakuvadzwa, rabha iri kuchembera, yakatsemuka, yakaremara kana kuputika, inofanira kutsiviwa.

(11) Paunenge uchiunganidza crankshaft, teerera kuisirwa kweiyo main bearing uye thrust bear. Tarisa crankshaft axial clearance uye simbisa iyo huru inotakura cap vertical mabhaudhi uye akachinjika mabhaudhi sezvinodiwa.
