Kuti zvive nyore kutsvagisa, bepa rino rinosarudza yakasarudzika giya giya mumuchina wekuvaka, kureva, akajairwa akatsika shaft zvikamu, izvo zvinoumbwa ne splines, circumferential surface, arc surfaces, mapfudzi, grooves, ring grooves, magiya nezvimwe zvakasiyana. mafomu.Geometric pamusoro uye geometric entity kuumbwa.Izvo chaizvo zvinodikanwa zvegiya shafts zvinowanzo kukwirira, uye kuomerwa kwekugadzirisa kwakakura, saka mamwe malink akakosha mukugadzirisa maitiro anofanirwa kusarudzwa nemazvo uye kuongororwa, senge zvinhu, involute ekunze splines, mabenchmark, mazino profile processing, kupisa kurapwa. , etc. Kuti uve nechokwadi chemhando uye mutengo wekugadzirisa wegiya shaft, akasiyana makiyi maitiro mukugadziriswa kwegiya shaft anoongororwa pazasi.

Kusarudzwa kwezvinhu zvegear shaft

Gear shafts mumashini ekutapurirana anowanzo kugadzirwa nesimbi makumi mana neshanu mumhando yepamusoro kabhoni simbi, 40Cr, 20CrMnTi mune alloy simbi, nezvimwewo. Kazhinji, inosangana nezvinodiwa zvesimba zvechigadzirwa, uye kupfeka kuramba kwakanaka, uye mutengo wakakodzera. .

Ukasha muchina tekinoroji ye gear shaft

Nekuda kwesimba rakawanda rinodiwa regiya shaft, kushandiswa kwesimbi yakatenderedzwa kune yakananga machining kunodya zvinhu zvakawanda uye basa, saka forgings inowanzo shandiswa sema blanks, uye yemahara forging inogona kushandiswa kune giya shafts ane hukuru hukuru;Die forgings;dzimwe nguva mamwe magiya madiki anogona kugadzirwa kuita chinhu chisina chinhu chine shaft.Munguva yekugadzira isina chinhu, kana iyo yekugadzira isina chinhu iri yemahara forging, iyo gadziriso inofanirwa kutevedzera iyo GB/T15826 standard;kana chisina chinhu chiri chekufa, iyo machining mvumo inofanirwa kutevedzera iyo GB/T12362 system standard.Kuforoma ma blanks kunofanirwa kudzivirira kukanganisa kuforoma sezviyo zvisina kuenzana, kutsemuka, uye kutsemuka, uye kunofanirwa kuyedzwa zvichiteerana neiyo yenyika forging evaluation standards.

Preliminary heat treatment uye rough turning process yema blanks

Iwo ma blanks ane akawanda magiya shafts anonyanya kuve epamusoro-mhando kabhoni structural simbi uye alloy simbi.Kuti uwedzere kuoma kwezvinhu uye kufambisa kugadzirisa, kurapwa kwekupisa kunotora normalizing kupisa kurapwa, zvinoti: normalizing process, tembiricha 960 ℃, kutonhora kwemhepo, uye kukosha kwekuoma kunoramba kuri HB170-207.Normalizing kupisa kupisa kunogonawo kuve nemhedzisiro yekunatsa kuforoma zviyo, yunifomu yekristaro chimiro, uye kubvisa kuumba kushushikana, uko kunoisa hwaro hwekutevera kupisa kurapwa.

Chinangwa chikuru chekutendeuka kwakashata ndechekucheka mvumo yekugadzira pamusoro peiyo isina chinhu, uye kutevedzana kwemuchina kwenzvimbo huru kunoenderana nekusarudzwa kwechikamu chekumisikidza referensi.Hunhu hweiyo giya shaft zvikamu ivo pachavo uye nekurongeka kwezvinodiwa zveimwe neimwe nzvimbo zvinokanganiswa nereferensi yekumisikidza.Iyo giya shaft zvikamu zvinowanzo shandisa axis senzvimbo yekumisikidza, kuitira kuti referensi ibatane uye ienderane nereferensi yedhizaini.Mukugadzira chaiko, denderedzwa rekunze rinoshandiswa seyakaomesesa yekumisikidza referensi, maburi epamusoro pamativi ese egiya shaft anoshandiswa seyakamira chaiyo referensi, uye kukanganisa kunodzorwa mukati me1/3 kusvika 1/5 yekukanganisa kwedimensional. .

Mushure mekugadzirira kupisa kwekupisa, iyo isina chinhu inoshandurwa kana kunyungudutswa pazviso zvese zvekupedzisira (yakamisikidzwa maererano nemutsara), uye ipapo maburi epakati pamativi ese ari maviri anoiswa chiratidzo, uye maburi epakati pamativi ese ari maviri anoboorwa, uyezve denderedzwa rekunze. inogona kurohwa.
