Izahlulo zeMoto zaseTshayina Zenziwe ngumgubo abavelisi besinyithi abavelisi kunye nababoneleli |Xuanyi

Izahlulo zemoto Ezenziwe ngokwezifiso ngabavelisi besinyithi somgubo obonisiweyo

Izahlulo zeMoto Zenziwe ngokwezifiso ngabavelisi besinyithi somgubo

Inkcazelo emfutshane:

Oku kubhekiselele kwintsimi ekhethekileyo yesinyithi somgubo, njengoko ubuninzi, i-porosity, izixhobo kunye neendlela zokunyanga ubushushu bezixhobo zesinyithi somgubo zichaphazela ngqo ukuqina kunye namandla. izinto eziphathekayo, ukuqina okuphezulu.Iindlela zonyango zokushisa ngokubanzi ziquka ukucima i-carburizing, i-carbonitriding, ukucima i-frequency quenching, i-low frequency quenching, ukucima ioli, njl.Inkqubo yokucima i-oyile ezinzileyo kunye nefanelekileyo igcina ubulukhuni bonyango oluzinzileyo.

Iithegi zeMveliso

Ngenxa yokusebenza okuphezulu kunye nexabiso eliphantsi lemathiriyeli yesinyithi yomgubo, iinxalenye zesinyithi somgubo zisetyenziswa ngakumbi nangakumbi kwimoto, kubandakanywa iindawo ezithatha ukothuka, isikhokelo, ipiston kunye nesihlalo sevalve ephantsi kwi-chassis yemoto; Inkqubo yebrake ine-ABS sensor, i-brake pad njalo njalo;Iinxalenye zempompo ziyimpompo yamafutha, impompo ye-oyile kunye nempompo yokuhambisa kwiindawo eziphambili; I-injini ine-conduit, iringi yesitulo, intonga yokudibanisa, isihlalo sokuthwala, amacandelo abalulekileyo enkqubo yevalve eguquguqukayo (VVT) kunye ne-exhaust. inkxaso yombhobho, etc.The transmission has hub synchronous kunye nesakhelo gear yeplanethi kunye nezinye iindawo.

I. Uphuhliso lwamalungu emoto olungumgubo

Ngophuhliso olukhawulezayo lweshishini le-auto laseTshayina, imarike yezahlulo zemoto nayo igcine i-trend ekhawulezayo.Ngo-2015, imveliso ye-auto yase-China yafikelela kwi-24.5033 yezigidi zeeyunithi, ibekwa kwindawo yokuqala kwishishini lemveliso ye-auto ye-world.China iphumelele ingeniso yentengiso ye-3.23 yetriliyoni yeyuan, phezulu malunga ne-10 ekhulwini ukusuka kunyaka ophelileyo.Kwelinye icala, emva kokungena kwe-China kwintlangano yorhwebo yehlabathi, kungekhona kuphela isethi epheleleyo yoshishino lweemoto zangaphandle ezifana nemikhosi, kunye ne-odolo yasekhaya enkulu yeengxenye zesinyithi somgubo, imveliso nganye, kunye neenkampani zomkhosi wangaphandle utyalo-mali kwilizwe lethu, ukwenza iseti epheleleyo yomgubo wemveliso yesinyithi ukubonelela ngeendawo ezikhulayo zemfuno, imfuno yokwandisa kuphuhliso lwamashishini esinyithi enyibiliki e China izise ithuba elinqabileyo.

Ukusuka kwimbono yexabiso lemveliso yomgubo wentsimbi yomgubo, ixabiso lemveliso linyuke ukusuka kwi-876.21 yezigidi zeeyuan ngo-2006 ukuya kwi-367.826 yezigidi zeeyuan ngo-2015, kunye nezinga lokukhula lonyaka elihlanganisiweyo le-17.28%, kwaye ligcine umkhwa wokukhula okukhawulezayo okuqhubekayo. , kunye nomgubo wentsimbi yemoto imfuno yemalike igcine umkhwa wokukhula okukhawulezayo.

Ukulawulwa kobunzima beemveliso ze-metallurgy jikelele zomgubo ngexesha lonyango lobushushu

Ubuninzi bepowder ye-atomized eqhelekileyo (kubandakanywa ne-carbon steel kunye ne-copper-carbon alloy steel steel) ingaphezulu kwe-6.9, kwaye ubunzima bokucima bunokulawulwa malunga ne-HRC30.

Ngokuqhelekileyo, ubuninzi be-powder pre-alloyed (AB powder) budlula i-6.95, kwaye ubunzima bokucima bunokulawulwa malunga ne-HRC35.

Iipowder eziphezulu ezifakwe ngaphambili kunye noxinano olukhulu kune-6.95 kunye nokucima ubunzima obulawulwa kwi-HRC40.

Iimveliso ze-metallurgy ze-powder ezenziwe kwezi zinto zingasentla zinezinzile kunye nezixhobo, kwaye ubunzima emva kokunyanga kobushushu buhlangabezana neemfuno ezihambelanayo, ngoko ke amandla abo okunyamezela kunye namandla okunyamezela aya kufikelela kwincopho engcono.

Ngaba unyango ubushushu ubulukhuni metallurgy umgubo ukufikelela 45 steel? Kakade unako!

Nangona kunjalo, ngenxa yokuba ubuninzi beemveliso ze-PM abukho ngaphezu kweNombolo ye-45 yensimbi, ubuninzi bezinto ezixinzelelekileyo ze-PM zivame ukuba yi-7.2 g / cm, ngelixa ubuninzi be-45 yensimbi yi-7.9 g / cm. yomgubo wesinyithi okanye unyango lobushushu obugqithisa kwi-HRC45 iya kwenza iimveliso zesinyithi somgubo zibe brittle ngenxa yokucima okuphezulu, okukhokelela ekomeleleni kwemveliso yomgubo wesinyithi.

Emva koko, siya kuthelekisa i-P / M yokwenza i-gear kunye ne-hobbing gear yomatshini.

1. Izinga eliphezulu lokusetyenziswa kwezinto, ukuya kuthi ga kwi-95%

2. Hayi okanye ukusika okuncinci kuphela kuyadingeka

3. Ukuhambelana kakuhle kwe-dimensional yamacandelo, ukuzinza okulungileyo kunye nokuchaneka okuphezulu.

4. Uthelekiso lwamandla: abavelisi besinyithi somgubo obuchwephesha balwenze ngcono uyilo lokubumba isinyithi somgubo, kwaye amandla okuqina kunye namandla acinezelayo egiya avelisiweyo asondele kuleyo yegiya yokuhombisa. Umzekelo, igiya eqhutywayo yebhokisi yemoto enokuhanjiswa okuphezulu. ukuqina ikwangumgubo wegiya yesinyithi.Ebonakalayo, igiya yomgubo wesinyithi iyasebenza kwaye ibanzi.

5. Ukubunjwa kwepowder usebenzisa ukubumba, kunokuvelisa enye iteknoloji yokusika i-hobbing ayikwazi ukuvelisa iimilo ezinzima.

6. Ngenxa yokuba ifanelekile kwimveliso yobuninzi, ukuveliswa kwemveliso kuphezulu kwaye ixabiso liphantsi kunokusika.

7. Ifanelekile kwimveliso yobuninzi, ngoko ke ixabiso likhuphisana ngokupheleleyo.
