Ukuhlaziywa kwezingxenye zomshini ezinembile: General Shaft

I. Izici zesakhiwo shaft evamile

Izingxenye zeshaft ziyizingxenye ezijikelezayo ubude bazo bukhulu kunobubanzi bazo.Zivame ukwakhiwa ngaphandle kwe-cylindrical surfaces, i-conical surfaces, izintambo, ama-splines, okhiye, izimbobo eziphambene, ama-grooves nezinye izindawo.Izingxenye ze-shaft ezijwayelekile zihlukaniswe izigaba ezine ngokuya nezici zazo zesakhiwo: izigxobo ezibushelelezi, izigxobo ezinyathelwe, izigxobo ezingenalutho kanye nezinsimbi ezimise okukhethekile (okuhlanganisa ama-crankshafts, ama-half shafts, ama-camshafts, ama-eccentric shafts, ama-cross shafts nama-spline shafts, njll.).

II.Ukubekezelelwa kwe-Dimensional shaft evamile

Izindawo eziyinhloko zezingxenye ze-shaft zivame ukuhlukaniswa zibe izigaba ezimbili: enye ijenali yangaphandle ehambisana nendandatho yangaphakathi ye-bearing, okungukuthi, ijenali yokusekela, esetshenziselwa ukucacisa indawo ye-shaft nokusekela i-shaft.Izinga lokubekezelela i-dimensional liphakeme, ngokuvamile I-IT5~IT7;olunye uhlobo ijenali esebenzisana nezingxenye ezihlukahlukene zokudlulisela, okungukuthi, ijenali ehambisanayo, nokubekezelela kwayo
Izinga liphansi kancane, ngokuvamile i-IT6~IT9.

III.Ubulukhuni bobuso be-shaft evamile

Indawo esebenza ngomshini ye-shaft inezidingo zokuqina kwendawo, ngokuvamile ezinqunywa ngokusekelwe ekusebenzeni nomnotho wokucubungula.Ubulukhuni obungaphezulu bejenali esekelayo ngokuvamile bungu-Ra0.2~1.6um, kanti ijenali ehambisanayo yengxenye yokudlulisela ingu-Ra0.4~3.2um.

IV.Ukuhlaziywa kobuchwepheshe bokucubungula izingxenye ze-shaft ezijwayelekile

Ezingxenyeni ezinezidingo zokunemba okuphezulu, ukugoqa nokuqeda kufanele kuhlukaniswe ukuze kuqinisekiswe ikhwalithi yezingxenye.Ukucutshungulwa kwezingxenye ze-shaft ngokuvamile kungahlukaniswa ngezigaba ezintathu: ukuphenduka okungalungile (ukuphenduka okungalungile kwendilinga yangaphandle, ukubhoboza izimbobo eziphakathi nendawo, njll.), ukuphenduka kwe-semi-finish (ukuguqula i-semi-finish yemibuthano yangaphandle ehlukahlukene, izinyathelo, nokugaya yezimbobo ezimaphakathi nendawo encane, njll.), ukugaya okumahhadlahhadla nokucolekile (ukugaya okumahhadlahhadla nokucolekile kwayo yonke imibuthano yangaphandle).Isigaba ngasinye sihlukaniswe cishe ngezinqubo zokwelashwa kokushisa.

VI.Izinto kanye nezikhala ze-shaft evamile

(1) Ngokuvamile, insimbi engu-45 ivame ukusetshenziswa njengempahla yezingxenye ze-shaft.Kumashafti anembayo ephakeme, 40Cr, GCr1565Mn, noma i-ductile iron ingasetshenziswa;ama-shafts anesivinini esikhulu, anomthwalo osindayo, 20CMnTi, 20Mn2B, 20C nezinye izinsimbi zokungcwaba noma i-38CrMoAl ingasetshenziswa.Insimbi ye-nitrided.
(2) Ezingxenyeni ezivamile ze-shaft, imigoqo eyindilinga nama-forging ngokuvamile asetshenziswa njengezikhala;ama-shafts amakhulu noma ama-shaft anezakhiwo eziyinkimbinkimbi, izingxenye zisetshenziswa.Ngemva kokuba okungenalutho kushisiwe futhi kwakhiwe, isakhiwo se-fiber yangaphakathi yensimbi singasatshalaliswa ngokulinganayo endaweni ukuze kutholwe amandla aphakeme okuqina, amandla okugoba namandla e-torsion.

VII.Ukwelashwa kokushisa kwe-shaft jikelele

I-1) Ngaphambi kokucutshungulwa, izikhala zokubumba kufanele zenziwe ngokwejwayelekile noma ziboshwe ukuze kucwengisiswe okusanhlamvu kwangaphakathi kwensimbi, kuqedwe ingcindezi yokubumba, kunciphise ubulukhuni bezinto ezibonakalayo, futhi kuthuthukise ukucutshungulwa.
2) Ukucisha kanye nokushisa kuvame ukuhlelwa ngemva kokuphenduka okungalungile nangaphambi kokuphenduka kancane kancane ukuze kutholwe izici ezinhle zokuhlanganisa.I-3) Ukucisha ubuso ngokuvamile kuhlelwa ngaphambi kokuqedwa, ukuze ukuguqulwa kwendawo okubangelwa ukucisha kulungiswe.I-4) Ama-Shafts anezidingo ezinembile, Ngemva kokucisha ingxenye noma ukugaya okuqinile, ukwelashwa kokuguga okushisa okuphansi kuyadingeka.
