Kuwunika kwa magawo omwe amapangidwa molondola: General Shaft

I. Makhalidwe a shaft wamba

Mbali za shaft ndi zigawo zozungulira zomwe kutalika kwake ndi kwakukulu kuposa m'mimba mwake.Nthawi zambiri amapangidwa ndi mawonekedwe akunja a cylindrical, mawonekedwe a conical, ulusi, ma splines, ma keyways, mabowo opingasa, ma grooves ndi malo ena.Zigawo za shaft zonse zimagawidwa m'magulu anayi molingana ndi mawonekedwe ake: ma shaft osalala, ma shaft opondapo, ma shafts obowoka ndi ma shaft opangidwa mwapadera (kuphatikiza ma crankshafts, theka shafts, camshafts, eccentric shafts, cross shafts and spline shafts, etc.).

II.Dimensional tolerances of general shaft

Mawonekedwe akuluakulu a zigawo za shaft nthawi zambiri amagawidwa m'magulu awiri: imodzi ndi magazini akunja omwe amafanana ndi mphete yamkati yazitsulo, ndiko kuti, magazini yothandizira, yomwe imagwiritsidwa ntchito pozindikira malo a shaft ndikuthandizira shaft.Mulingo wololera wowoneka bwino ndi wapamwamba, nthawi zambiri Ndi IT5~IT7;mtundu wina ndi magazini yomwe imagwirizana ndi magawo osiyanasiyana opatsirana, ndiko kuti, magazini yofananira, ndi kulolera kwake.
Mulingo ndi wotsika pang'ono, nthawi zambiri IT6~IT9.

III.Pamwamba pamakhala makulidwe a general shaft

Malo opangidwa ndi makina a shaft ali ndi zofunikira zowonongeka, zomwe nthawi zambiri zimatsimikiziridwa kutengera ntchito ndi chuma cha processing.Kuvuta kwapamwamba kwa magazini yothandizira nthawi zambiri kumakhala Ra0.2 ~ 1.6um, ndipo magazini yofananira ya gawo lopatsira ndi Ra0.4 ~ 3.2um.

IV.Kusanthula kwaukadaulo waukadaulo wamagawo wamba wa shaft

Kwa magawo omwe ali ndi zofunikira zolondola kwambiri, roughing ndi kumaliza ziyenera kupatulidwa kuti zitsimikizire kuti zigawozo zili bwino.Kusintha kwa magawo a shaft nthawi zambiri kumatha kugawidwa m'magawo atatu: kutembenuka movutikira (kutembenuza movutikira kwa bwalo lakunja, kubowola mabowo apakati, ndi zina zambiri), kutembenuka komaliza (kutembenuza komaliza kwa mabwalo osiyanasiyana akunja, masitepe, ndikupera. za maenje apakati ndi malo ang'onoang'ono, ndi zina zotero), kugaya movutikira komanso kosalala (kugaya kozungulira kozungulira kozungulira).Gawo lirilonse limagawidwa kukhala njira zochizira kutentha.

VI.Zipangizo ndi zosasoweka za general shaft

(1) Nthawi zambiri, zitsulo 45 zimagwiritsidwa ntchito ngati zida zopangira magawo.Pamiyendo yolondola kwambiri, 40Cr, GCr1565Mn, kapena chitsulo cha ductile chingagwiritsidwe ntchito;pazitsulo zothamanga kwambiri, zolemetsa kwambiri, 20CMnTi, 20Mn2B, 20C ndi zitsulo zina zotsekemera kapena 38CrMoAl zingagwiritsidwe ntchito.Nitrided zitsulo.
(2) Pazigawo za shaft wamba, mipiringidzo yozungulira ndi zomangira zimagwiritsidwa ntchito ngati zopanda kanthu;pazitsulo zazikulu kapena zitsulo zokhala ndi zovuta, zigawo zimagwiritsidwa ntchito.Chopandacho chikatenthedwa ndikupangitsidwa, mawonekedwe amkati achitsulo amatha kugawidwa mozungulira kuti apeze mphamvu zochulukirapo, mphamvu yopindika ndi mphamvu ya torsion.

VII.Kutentha mankhwala ambiri kutsinde

1) Musanayambe kukonza, zopangira zopangira ziyenera kusinthidwa kapena kusinthidwa kuti ziyeretse zitsulo zamkati, kuthetsa kupsinjika, kuchepetsa kuuma kwa zinthu, ndikuwongolera magwiridwe antchito.
2) Kuzimitsa ndi kutentha nthawi zambiri kumakonzedwa pambuyo potembenuka movutikira komanso musanamalize kutembenuka kuti mupeze mawonekedwe abwino amakina.3) Kuzimitsa kwapamwamba kumakonzedwa musanamalize, kotero kuti kusinthika komweko komwe kumachitika chifukwa chozimitsa kutha kukonzedwa.4) Mitsuko yokhala ndi zofunikira zolondola, Pambuyo pozimitsa pang'ono kapena kugaya movutikira, chithandizo cha ukalamba chotsika chimafunika.
