Ibyiza bya Excavator Hasi Roller

Main shaft :Material ni 50Mn yujuje ubuziranenge bwa karubone yubatswe, hamwe na C iri hagati ya 0.48 kugeza 0.56%, Si ibirimo kuva 0.17 kugeza 0.37%, Mn ibirimo kuva kuri 0.7 kugeza 1.0%, S ibirimo biri munsi ya 0.035%, P ibirimo kuva munsi ya 0.035%, na Cr ibirimo kuva munsi ya 0.25 kugeza 0.30%, Ni ibirimo kuva munsi ya 0,30%, na Cu ibirimo biri munsi ya 0.25% .Muri bo, Mn nikintu cyingenzi mubyuma bivangavanze, aribyo Irashobora kunonosora ihindagurika hamwe na plastike yibikoresho, ikemeza gukomera bihagije no kwambara birwanya.Nyuma yo kuvura ubushyuhe, 50Mn ibyuma bifite imbaraga nubukomezi, kwinjira neza, igorofa ryimbitse, hamwe na pearlite nziza, hamwe nubukorikori bwiza.

Ibishushanyo mbonera bya shaft nkuru bisaba ubujyakuzimu bwa mm 2 kugeza kuri 7 z'uburemere bukomeye hamwe n'ubushyuhe bwa 50 kugeza 62 HRC.

Umubiri :Kugirango tunoze imyambarire yimyambarire yatroller's umubiri, ibikoresho ni 40Mn2 alloy ibyuma byubatswe, hamwe na C iri hagati ya 0.37 na 0.44%, ibirimo Si biva kuri 0.17 kugeza 0.37%, Mn ibirimo kuva kuri 1.4 kugeza 1.8%, Ibirimo P biri munsi ya 0.030%, na S birimo kuva munsi ya 0.030%.

Uwiteka Urupapuro rwo hasiumubiri ubumbabumbwe nuburyo bwo guhimba.Nyuma yo kubumba, umubiri wikiziga gikonje urahindurwa kugirango ugere ku gukomera kwa 26-32HRC kugirango ugumane imbaraga nyinshi, plastike, ubukana, hamwe nubukanishi muri rusange imbere yumubiri.Ubuso bwumubiri wibiziga bikorerwa kuzimya kugirango byongere ubukana no kwambara birwanya ubuso bwa gari ya moshi. Ubukomezi bwo kuzimya ni 50-58HRC, hamwe nubujyakuzimu bwa 6-12mm.Ibi bivamo isano yibanze hagati ya gari ya moshi igoye hamwe nu munyururu uhuza gukomera (48-58HRC).

Ikirango:Ingano n'ubuso bukabije bwaO-impetabigomba kuba bihuye nibisabwa kugirango igishushanyo mbonera.Ubuso bwo gushyingiranwa bugomba kuzunguruka, kandi hagomba kubaho isuku ya burrs yose nu mpande zikarishye.

Kureremba kashe ya reberi na O-impetabigomba guhitamo kuva murwego rwohejuru rwa butyl reberi. Diameter yimbere, ubunini bwurudodo, elastique, gukomera (Shore), hamwe no kurangiza hejuru bigomba kubahiriza ibipimo.Mbere yo guterana, ibintu byose byavuzwe haruguru bigomba kugenzurwa no kubisabwa hakurikijwe ibipimo byavuzwe haruguru mbere yo kwishyiriraho.

Icyuho :Ihanagura hagati ya axle nyamukuru na hub ijyanye narollerumubiri ugomba kuba mm 0.2-0.4 mm.Iyo kuzunguruka, ntihakagombye kubahoikibazon'imikorere myiza yo gufunga, nta mavuta yamenetse.

Amavuta :Amavuta yo gutwarakuzungurukar bigomba guterwa hakoreshejwe pompe yamavuta.Iyo bibaye ngombwa, amavuta yo kwisiga arashobora kwiyongera muburyo bukwiye.Mbere yo gutera inshinge amavuta, amavuta ashaje agomba kuvaho.Hanyuma, amavuta mashya agomba kongerwamo umwobo wamavuta kugeza amavuta asohotse.Mugihe cyo gutera amavuta yo gusiga, umugozi wa hub ugomba gukurwaho, hanyuma impera yamavuta yigikoresho cyamavuta igomba gukanda ku rutugu mumuyoboro wamavuta. Umuyoboro ukabije wamashanyarazi ugomba kugenzurwa hagati ya 157-255 Nm.
