Chopukusira chopanda pakati

Pogaya wopanda Center:

Makina opukutira opanda Center ndi makina akupera wamba, omwe amadziwikanso kuti makina opangira cylindrical. Kugwiritsiridwa ntchito kwake kwakukulu ndi makampani opanga zida zamakina, omwe amagwiritsidwa ntchito pokonza mitundu yosiyanasiyana ya magawo ang'onoang'ono a shaft, kuphatikiza magazini, shaft unyolo, kupopera kosintha, ndi zina zambiri.

Makhalidwe akupera a chopukusira wopanda centerless:

Makina opukutira opanda pakati amatha kukwaniritsa nkhanza zotsika, nthawi zambiri amatha kufikira kulondola kwa T6 ~ IT, ndipo kuuma kwapamtunda komwe kumapezeka ndi Ra125 ~ 0Oum; Pamwamba pa roughness wa superfinishing akupera ndi galasi akupera akhoza kufika Ra0.05um.

2, makina opukutira opanda pakati amatha kupera zitsulo zamitundu yonse, zitsulo zotentha za alloy ndi aloyi olimba ndi zida zina zovuta.

3, makina opangira cylindrical opanda pakati popanga processing. Chifukwa gudumu lopera likhoza kukonzedwa m'mawonekedwe osiyanasiyana malinga ndi zofunikira za makina, m'pofunika kugaya mawonekedwe ovuta mwachidule. Amagwiritsidwa ntchito kwambiri mu mawonekedwe akupera kuti achepetse njira yapakatikati.

4, centerless chopukusira akupera malire ndi laling'ono kwambiri, oyenera kuponyera, kufa forging, stamping mbali ya processing kutsatira, kuti apititse patsogolo kulondola kwa mbali zopanda kanthu, kuchepetsa roughness pamwamba.

5, makina akupera opanda pakati ndi oyenera zida basi, akhoza konza ndondomeko akupera.

Choyamba, kugaya mphamvu

①. Gwero ndi kuwonongeka kwa mphamvu yopera

Pali mphamvu zofanana ndi zotsutsana zomwe zimagwira pa gudumu lopera ndi workpiece panthawi yopera. Mphamvu yopangidwa pogaya imatchedwa grinding force (kudula mphamvu). Mphamvu yogaya makamaka imapangidwa ndi magawo awiri: njere yowonongeka idzapangitsa kuti pulasitiki iwonongeke kwambiri podula zitsulo, ndipo mphamvu yodula imapangidwa; The akupera mphamvu kwaiye pakati tinthu ndi workpiece pamwamba pa kudula.

(2) Chikoka cha mphamvu yopera pa makina

Pokupera, tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, ndipo fillet R ya m'mphepete mwake nthawi zambiri imakhala yokulirapo kuposa yodula kumbuyo, chifukwa chake kufinya kwa radial kwa tinthu ting'onoting'ono tomwe timagwirira ntchito kumakhala kwakukulu, nthawi zambiri Fp=( 2 ~ 3)FC. Chifukwa cha mphamvu yayikulu yozungulira, njira yopangira makina opangidwa ndi chida cha makina, chogwirira ntchito ndi gudumu lopera limatulutsa mapindikidwe akulu otanuka, omwe amakhudza kulondola kwakupera. Ngati workpiece ndi opunduka chifukwa cha zochita za ma radial mphamvu ndi tangential mphamvu, kayendedwe wachibale wa olamulira ake ndi e, amene adzachititsa m'mimba mwake cholakwika workpiece.

Kusinthika kwa dongosolo lamachitidwe opangidwa ndi mphamvu ya radial nthawi zambiri kumapangitsa kuchuluka kwenikweni kwa kudula kumbuyo kukhala kosiyana ndi mtengo wamtengo womwe ukuwonetsedwa pa kuyimba kwa magudumu. Chifukwa chake, njira yoyenera yogaya ndikuyimitsa pambuyo pa chakudya kuti muchepetse kupindika komwe kumayambitsidwa ndi mphamvu za radial. Kupera kotereku kopanda chakudya kumatchedwa kugaya kopepuka kapena kugaya kosanyezimira. Pogaya tsinde lowonda, chogwiriracho chimadulidwa kukhala ng'oma ndi mphamvu za radial. Makhalidwe a gudumu lopera, kukula kwa gudumu logaya, zida zogwirira ntchito, kuchuluka kwakupera (ap, f) kumakhudza kwambiri mphamvu yamagetsi.

Gawani

Ena:

Kodi tiyenera kulabadira chiyani pamene kupukuta makina zitsulo zosapanga dzimbiri chubu kuzungulira?
