Izinkambu zesicelo ze-forgings shaft ziyi
Ama-shaft forgings (izingxenye zemishini) Ama-shaft forging yizinto eziyisilinda ezigqokwa phakathi ne-bearing noma phakathi nesondo noma phakathi negiya, kodwa ezimbalwa ziyizikwele. I-shaft iyingxenye yomshini esekela ingxenye ejikelezayo futhi izungezisa ngayo ukuze idlulise ukunyakaza, i-torque noma izikhathi zokugoba. Ngokuvamile, iwumumo wenduku yensimbi, futhi ingxenye ngayinye ingaba nobubanzi obuhlukile. Izingxenye zomshini ezenza ukunyakaza kwe-slewing zifakwe ku-shaft. Igama lesiShayina shaft forging uhlobo shaft, mandrel, drive shaft material ukusetshenziswa 1, carbon steel 35, 45, 50 kanye nezinye izinga okusezingeni carbon steel kwesakhiwo ngenxa izici zayo eliphezulu olunzulu mechanical, izicelo ngaphezulu, okuyinto 45 steel isetshenziswa kabanzi. Ukuze uthuthukise izakhiwo zayo zemishini, ukujwayelekile noma ukucisha kanye nokushisa kufanele kwenziwe. Kumashafu esakhiwo angabalulekile noma anamandla aphansi, izinsimbi ze-carbon structural ezifana ne-Q235 ne-Q275 zingasetshenziswa. I-2, insimbi ye-alloy Insimbi ye-alloy inezakhiwo eziphakeme zemishini, kodwa intengo ibiza kakhulu, isetshenziselwa kakhulu ama-shafts anezidingo ezikhethekile. Isibonelo, ama-shaft anesivinini esikhulu asebenzisa ama-sliding bearings, ngokuvamile asetshenziswa i-low-carbon alloy structural steels njenge-20Cr kanye ne-20CrMnTi, angathuthukisa ukumelana nokugqokwa kwejenali ngemva kokungcwatshwa kwe-carburizing kanye nokucisha; i-rotor shaft ye-turbo generator isebenza ngaphansi kokushisa okuphezulu, isivinini esikhulu kanye nezimo zomthwalo osindayo. Ngezakhiwo ezinhle zemishini yokushisa okuphezulu, izinsimbi ze-alloy structural ezifana ne-40CrNi kanye ne-38CrMoAlA zivame ukusetshenziswa. I-blank of the shaft ikhethwa ukwakhiwa, kulandelwa insimbi eyindilinga; ngezakhiwo ezinkulu noma eziyinkimbinkimbi, insimbi ekhonjiwe noma i-ductile iron ingacatshangelwa. Isibonelo, ukwakhiwa kwe-crankshaft kanye ne-camshaft kusuka ku-ductile iron kunezinzuzo zezindleko eziphansi, ukumuncwa okuhle kokudlidliza, ukuzwela okuphansi ekugxilweni kwengcindezi, namandla amahle. Imodeli yemishini ye-shaft yi-beam, ejikeleziswa kakhulu, ngakho-ke ukucindezeleka kwayo kuvame umjikelezo we-symmetric. Izindlela zokwehluleka okungenzeka zihlanganisa ukuphuka kokukhathala, ukuphuka komthwalo omningi, kanye nokuwohloka okunwebeka ngokweqile. Ezinye izingxenye ezinamahabhu zivame ukufakwa ku-shaft, ngakho-ke ama-shaft amaningi kufanele enziwe ama-shaft anyathelwe ngenani elikhulu lomshini. Ukuhlukaniswa Kwesakhiwo Idizayini Yesakhiwo Idizayini yesakhiwo yeshafti iyisinyathelo esibalulekile ekunqumeni ukuma okunengqondo kanye nobukhulu besakhiwo beshaft. Iqukethe uhlobo, usayizi kanye nesimo sengxenye efakwe ku-shaft, indlela ingxenye egxilwe ngayo, imvelo, isiqondiso, ubukhulu nokusabalalisa komthwalo, uhlobo nobukhulu bokuthwala, ukungenalutho kwe-shaft, inqubo yokukhiqiza nokuhlanganisa, ukufakwa nokuthutha, i-shaft I-deformation nezinye izici zihlobene. Umklami angakwazi ukuklama ngokuvumelana nezidingo ezithile ze-shaft. Uma kunesidingo, izikimu eziningana zingaqhathaniswa ukuze ukhethe umklamo ongcono kakhulu.
Okulandelayo yizimiso zokuklama isakhiwo seshaft jikelele
1. Yonga izinto ezisetshenziswayo, yehlisa isisindo, futhi usebenzise umumo wamandla alinganayo. Umumo we-coefficient wesigaba esinqamulayo sobukhulu noma esikhulu.
2, kulula ukuyibeka ngokunembile, ukuzinzisa, ukuhlanganisa, ukuqaqa futhi ulungise izingxenye ku-shaft.
3. Sebenzisa izindlela ezehlukene zesakhiwo ukuze unciphise ukugxilisa ingqondo nokuthuthukisa amandla.
4. Kulula ukwenza nokuqinisekisa ukunemba.
Ukuhlukaniswa kwama-shaft Amashafu avamile angahlukaniswa abe ama-crankshaft, ama-shaft aqondile, ama-flexible shafts, ama-shaft aqinile, ama-hollow shafts, ama-shaft aqinile, kanye nama-flexible shafts (ama-flexible shafts) kuye ngokuthi ukwakheka kwe-shaft kunjani.
I-shaft eqondile ingabuye ihlukaniswe ibe
1 shaft, engaphansi kokubili kokugoba kanye ne-torque, futhi iwumshini ovame kakhulu emishinini, njengamashafti kwizinciphisi zejubane ezihlukahlukene.
I-2 mandrel, esetshenziselwa ukusekela izingxenye ezijikelezayo kuphela ukuthwala isikhathi sokugoba ngaphandle kokudlulisa i-torque, ukujikeleza okuthile kwe-mandrel, njenge-ekseli yesitimela sesitimela, njll., ezinye ze-mandrel azijikelezi, njenge-shaft esekela i-pulley .
I-3 Transmission shaft, esetshenziselwa ukudlulisa i-torque ngaphandle komzuzu wokugoba, njenge-axis ende yokubona kumshini wokuhambisa u-crane, shaft yokushayela yemoto, njll.
Impahla ye-shaft ikakhulukazi i-carbon steel noma i-alloy steel, futhi i-ductile iron noma i-alloy cast iron nayo ingasetshenziswa. Amandla okusebenza we-shaft ngokuvamile ancike emandleni nokuqina, futhi isivinini esikhulu sincike ekuzinzeni kokudlidliza. Isicelo sohlelo Lokusebenza Ukuqina kwe-torsional Ukuqina kwe-torsional ye-shaft kubalwa njengenani lokuguquguquka kokuguquguquka kwe-shaft ngesikhathi sokusebenza, kukalwa ngokwe-engeli yokuguquguquka imitha ngayinye yobude be-shaft. Ukuguqulwa kwe-torsional ye-shaft kufanele kuthinte ukusebenza nokunemba kokusebenza komshini. Isibonelo, uma i-angle ye-torsion ye-camshaft yenjini evuthayo yangaphakathi inkulu kakhulu, izothinta isikhathi esifanele sokuvula nokuvala kwe-valve; i-torsion angle ye-transmission shaft ye-gantry crane motion mechanism izothinta ukuvumelanisa kwesondo lokushayela; Kudingeka ukuqina okukhulu kwe-torsional kumashafti asengozini yokudlidliza kwe-torsional kanye nama-shaft ohlelweni lokusebenza.
Izidingo zobuchwepheshe 1. Ukunemba komshini
1) Ukunemba kwe-Dimensional Ukunemba kwe-dimensional kwezingxenye ze-shaft ikakhulukazi kubhekisela kububanzi nokunemba kwe-dimensional kwe-shaft kanye nokunemba kwe-dimensional kobude be-shaft. Ngokwezidingo zokusetshenziswa, ukunemba kobubanzi bejenali eyinhloko kuvamise ukuba yi-IT6-IT9, kanti ijenali yokunemba nayo ifika ku-IT5. Ubude be-shaft ngokuvamile buchazwa njengosayizi wegama. Ngobude besinyathelo ngasinye se-shaft stepped, ukubekezelelana kunganikezwa ngokuvumelana nezidingo zokusetshenziswa.
2) Ukunemba kweJiyomethri Izingxenye zeshaft ngokuvamile zisekelwa kumajenali amabili. Lawa majenali amabili abizwa ngokuthi amajenali asekelayo futhi ayireferensi yomhlangano we-shaft. Ngaphezu kokunemba kwe-dimensional, ukunemba kwejometri (ukuyindilinga, isilinda) kwejenali esekelayo ngokuvamile kuyadingeka. Kumajenali wokunemba okuvamile, iphutha lejometri kufanele likhawulelwe ekubekezeleleni kobubanzi. Uma izidingo ziphakeme, amanani okubekezelela avunyelwe kufanele acaciswe engxenyeni yomdwebo.
3) Ukunemba kokuma okuhlangene Ukubumbana phakathi kwamajenali okukhwelana (amajenali amalungu okushayela ahlangene) ezingxenyeni ze-shaft ngokuhlobene namajenali asekelayo kuyisidingo esivamile sokunemba kwawo okuhambisanayo. Ngokuvamile, i-shaft enembayo evamile, ukunemba okufanayo ngokuphathelene nokuphuma kwe-radial kwejenali yokusekela ngokuvamile ingu-0.01-0.03 mm, futhi i-shaft enembayo ephezulu ingu-0.001-0.005 mm. Ukwengeza, ukunemba kwe-mutual positional kubuye kube yi-coaxiality yezindawo ze-cylindrical zangaphakathi nangaphandle, i-perpendicularity yobuso bokuphela obubekwe nge-axially kanye nomugqa we-axial, nokunye okunjalo. 2, ubuhwaqane bobuso Ngokusho kokunemba komshini, isivinini sokusebenza, izidingo zokuqina kwezingxenye ze-shaft nazo zihlukile. Ngokuvamile, ubulukhuni obuphezulu be-Ra yejenali esekelayo yi-0.63-0.16 μm; ubulukhuni obuphezulu u-Ra wejenali ehambisanayo ngu-2.5-0.63 μ m.
Ubuchwepheshe bokucubungula 1, ukukhethwa kwezingxenye ze-shaft ezibonakalayo zezingxenye ze-shaft, Ikakhulukazi ngokusekelwe emandleni, ukuqina, ukumelana nokugqoka kanye nenqubo yokukhiqiza ye-shaft, nokulwela umnotho.
