Ongororo yeakajairwa nemakina zvikamu: General Shaft

I. Mamiriro ezvinhu e general shaft

Shaft zvikamu zvikamu zvinotenderera izvo kureba kwakakura kudarika dhayamita yazvo.Iwo anowanzo kuumbwa ekunze cylindrical nzvimbo, conical nzvimbo, shinda, splines, keyways, transverse maburi, grooves uye mamwe maficha.General shaft zvikamu zvakakamurwa kuita zvikamu zvina zvichienderana nehunhu hwazvo: shafts yakatsetseka, shafts yakatsikwa, makomba mashaft uye akasarudzika-shaft shafts (kusanganisira crankshafts, hafu shafts, camshafts, eccentric shafts, cross shafts uye spline shafts, nezvimwewo).

II.Dimensional kushivirira kwe general shaft

Nzvimbo huru dzezvikamu zve shaft dzinowanzopatsanurwa muzvikamu zviviri: imwe ibhuku rekunze rinoenderana nemhete yemukati yekutakura, kureva, bhuku rekutsigira, iro rinoshandiswa kuona nzvimbo yeshaft uye kutsigira shaft.Iyo dimensional kushivirira nhanho yakakwirira, kazhinji Iri IT5~IT7;imwe mhando ijenari rinoshanda pamwe nezvikamu zvakasiyana-siyana zvekutapurirana, ndiko kuti, bhuku rinoenderana, uye kushivirira kwayo.
Iyo nhanho yakadzikira zvishoma, kazhinji IT6~IT9.

III.Surface roughness ye general shaft

Iyo yakashongedzwa pamusoro pe shaft ine pamusoro roughness zvinodiwa, izvo zvinowanzo temwa zvichienderana nekuita uye hupfumi hwekugadzirisa.Kushata kwepamusoro kwejenari rinotsigira kunowanzova Ra0.2 ~ 1.6um, uye jenari inofananidzwa yechikamu chekutumira iRa0.4 ~ 3.2um.

IV.Ongororo yekugadzira tekinoroji yeakajairwa shaft zvikamu

Kune zvikamu zvine zvakakwirira zvinodiwa, roughing uye kupedzisa kunofanira kuparadzaniswa kuti kuve nechokwadi chemhando yezvikamu.Kugadziriswa kwezvikamu zveshaft kunogona kukamurwa kuita matanho matatu: kutenderera kwakakasharara (kutenderera kwekunze kwedenderedzwa, kuchera makomba epakati, nezvimwewo), semi-yekupedzisira kutendeuka (semi-yekupedzisira kutendeuka kweakasiyana ekunze madenderedzwa, nhanho, uye kugaya. yemakomba epakati uye madiki madiki, nezvimwewo) , hutsinye uye kugaya (kukuya uye kukuya kwakanaka kwese madenderedzwa ekunze).Imwe neimwe nhanho yakakamurwa kuita kupisa kurapwa maitiro.

VI.Zvishandiso uye ma blanks e general shaft

(1) Kazhinji, 45 simbi inowanzoshandiswa sechinhu chezvikamu zveshaft.Kune mashaft ane yakakwirira chaiyo, 40Cr, GCr1565Mn, kana ductile iron inogona kushandiswa;ye-high-speed, heavy-load shafts, 20CMnTi, 20Mn2B, 20C uye mamwe masimbi emotokari kana 38CrMoAl anogona kushandiswa.Nitrided simbi.
(2) Kune zvikamu zvakajairika zveshaft, mabara akatenderedzwa uye forging anowanzoshandiswa sezvisina chinhu;kune mashefu makuru kana shafts ane zvimiro zvakaoma, zvikamu zvinoshandiswa.Mushure mekunge iyo isina chinhu ichidziya uye nekuumbwa, iyo yemukati fiber chimiro chesimbi inogona kugovaniswa zvakaenzana pamusoro pepamusoro kuti iwane yakakwira kusimba simba, kubhenda simba uye torsion simba.

VII.Kupisa kurapwa kwe general shaft

1) Isati yagadziriswa, ma blanks ekugadzira anofanirwa kuve akajairwa kana kuvharirwa kuti agadzirise zviyo zvemukati zvesimbi, kubvisa kushushikana kwekumanikidza, kuderedza kuoma kwezvinhu, uye kugadzirisa mashandiro.
2) Kudzima uye kudzikisira kunowanzo kurongwa mushure mekutenderera kwakashata uye kusati kwapera kutendeuka kuti uwane yakanaka yakazara mekinika zvivakwa.3) Kudzima kwepamusoro kunowanzo kurongwa kusati kwapera, kuitira kuti deformation yemunharaunda inokonzerwa nekudzima inogona kugadziriswa.4) Shafts ine chaiyo zvinodiwa, Mushure mekudzima zvishoma kana rough kukuya, yakaderera tembiricha kuchembera kurapwa kunodiwa.
