Iyo minda yekushandisa ye forgings shaft ndeye
Shaft forgings (mechanical components) Shaft forgings zvinhu zvecylindrical zvinopfekwa pakati pebereki kana pakati pevhiri kana pakati pegiya, asi mashoma ane square.Shaft inhengo yemuchina inotsigira chikamu chinotenderera uye chinotenderera nacho kufambisa mafambiro, torque kana kukotama nguva.Kazhinji, chimiro chesimbi tsvimbo, uye chikamu chimwe nechimwe chinogona kuva nehupamhi hwakasiyana.Zvikamu zvemuchina zvinogadzira kufamba kwekuuraya zvakaiswa pa shaft.Chinese zita shaft forging type shaft, mandrel, drive shaft material shandisa 1, carbon steel 35, 45, 50 uye mamwe emhando yepamusoro kabhoni dhizaini simbi nekuda kwehupamhi hwayo hwemakina ezvivakwa, mamwe maapplication, ayo makumi mana neshanu simbi anoshandiswa zvakanyanya.Kuti uvandudze maitiro ayo emagetsi, normalizing kana quenching uye tempering inofanira kuitwa.Kune zvimiro zveshaft izvo zvisina kukosha kana zvine simba rakaderera, kabhoni structural simbi seQ235 uye Q275 inogona kushandiswa.2, alloy simbi Alloy simbi ine yakakwirira michina zvivakwa, asi mutengo unodhura, unonyanya kushandiswa kune shafts ane zvakakosha zvinodiwa.Semuyenzaniso, high-speed shafts vachishandisa sliding bearings, anowanzo shandiswa low-carbon alloy structural steels akadai 20Cr uye 20CrMnTi, anogona kuvandudza kupfeka kuramba rejenari pashure carburizing uye kudzima;iyo rotor shaft ye turbo jenareta inoshanda pasi pekushisa kwepamusoro, kukurumidza uye inorema mamiriro ezvinhu.Iine yakanaka yakakwira tembiricha yemagetsi zvivakwa, alloy zvimiro simbi senge 40CrNi uye 38CrMoAlA inowanzoshandiswa.Iyo isina chinhu ye shaft inosarudzwa forgings, inoteverwa nesimbi yakatenderera;kune zvimiro zvakakura kana zvakaoma, simbi yakakandwa kana ductile iron inogona kutariswa.Semuenzaniso, kugadzirwa kwe crankshaft uye camshaft kubva kune ductile iron ine zvakanakira mutengo wakaderera, yakanaka vibration absorption, yakaderera senitivity kune stress concentration, uye simba rakanaka.Iyo mechanical model of shaft ndiyo danda, iro rinonyanya kutenderera, saka kushungurudzika kwayo kunowanzoita symmetric cycle.Inogona kutadza nzira dzinosanganisira kuneta kutyoka, kuwandisa kutsemuka, uye yakawandisa elastic deformation.Zvimwe zvikamu zvine hubs zvinowanzoiswa pane shaft, saka mashaft mazhinji anofanirwa kugadzirwa mumashaft akatsikwa ane huwandu hukuru hwekugadzira.Structural Classification Structural Dhizaini Dhizaini yemagadzirirwo eshaft inhanho yakakosha pakuona chimiro chinonzwisisika uye chiyero chechimiro cheshaft.Iyo ine mhando, saizi uye chinzvimbo chechikamu chakamisikidzwa pane shaft, nzira iyo chikamu chakagadziriswa, hunhu, kutungamira, ukuru uye kugoverwa kwemutoro, mhando uye saizi yekutakura, isina chinhu cheshaft, iyo yekugadzira uye yekuunganidza maitiro, kuisirwa uye kutakura, shaft Iyo deformation uye zvimwe zvinhu zvine hukama.Mugadziri anogona kugadzira zvinoenderana nezvinodiwa zve shaft.Kana zvichidikanwa, zvirongwa zvakawanda zvinogona kufananidzwa nekusarudza yakanakisa dhizaini.

Aya anotevera ndiwo akajairwa shaft chimiro dhizaini misimboti

1. Chengetedza zvinhu, kuderedza uremu, uye shandisa yakaenzana-simba chimiro.Dimensional kana yakakura chikamu coefficient cross-sectional chimiro.

2, zviri nyore kunyatso kumisa, kudzikamisa, kuunganidza, disassemble uye kugadzirisa zvikamu pane shaft.

3. Shandisa maitiro akasiyana-siyana ekugadzirisa kuderedza kushungurudzika uye kuvandudza simba.

4. Zviri nyore kugadzira uye kuve nechokwadi chekururama.

Kupatsanurwa kweshafts Mashaft akajairika anogona kukamurwa kuita crankshafts, shafts dzakatwasuka, dzinochinjika shafts, dzakasimba shafts, hollow shafts, dzakaomarara shafts, uye inochinjika shafts (inochinjika shafts) zvichienderana nechimiro cheiyo shaft.

Iyo shaft yakatwasuka inogona kukamurwazve kuita

1 shaft, iyo inoiswa pasi pese kukotama nguva uye torque, uye ndiyo yakajairika shaft mumakina, senge shafts mune akasiyana spidhi anoderedza.

2 mandrel, yaishandiswa kutsigira zvikamu zvinotenderera chete kutakura nguva yekukotama pasina kuendesa torque, kumwe kutenderera kwema mandrel, senge axle yechitima chechitima, nezvimwewo, mamwe mandrel haatenderere, senge shaft inotsigira pulley. .

3 Transmission shaft, inonyanya kushandiswa kufambisa torque pasina kukotama nguva, senge refu optical axis mune crane inofamba michina, dhiraivha shaft yemotokari, nezvimwe.

Izvo zvinhu zveshaft zvakanyanya kabhoni simbi kana alloy simbi, uye ductile iron kana alloy cast iron inogona kushandiswa zvakare.Iko kushanda kweshaft kazhinji kunoenderana nesimba uye kuoma, uye kumhanya kwakanyanya kunoenderana nekugadzikana kwekuzunguza.Chikumbiro Chikumbiro cheTorsional stiffness Iyo kuomarara kweshaft inoverengerwa sehuwandu hwekutenderera kweshaft panguva yekushanda, kuyerwa maererano neiyo torsion angle pamita yehurefu hweshaft.Iyo torsional deformation ye shaft inofanirwa kukanganisa mashandiro uye kushanda kwayo kwemuchina.Semuenzaniso, kana torsion angle ye camshaft yejini inopisa mukati yakakura zvikuru, ichakanganisa nguva yakarurama yekuzarura nekuvhara kwevhavha;iyo torsion angle yekutumira shaft ye gantry crane motion mechanism ichakanganisa kuwiriraniswa kwevhiri rekutyaira;Iyo yakakura torsional kuomarara inodiwa kune shafts ari panjodzi yekuzunza kudengenyeka uye shafts mune inoshanda sisitimu.

Technical zvinodiwa 1. Machining kururama

1) Kurongeka kwedimensional Kurongeka kwezvikamu zveshaft zvinonyanya kureva dhayamita uye dimensional kurongeka kweshaft uye kurongeka kwehurefu hwehurefu.Zvinoenderana nezvinodiwa zvekushandisa, iko kurongeka kweiyo huru yejenari dhayamita inowanzoita IT6-IT9, uye iyo chaiyo jenari inokwirawo kuIT5.Kureba kweshaft kunowanzotsanangurwa sehukuru hwezita.Kune imwe neimwe nhanho kureba kweiyo yakatsika shaft, iyo kushivirira inogona kupihwa zvinoenderana nezvinodiwa zvekushandisa.

2) Geometric accuracy Shaft zvikamu zvinowanzo tsigirwa pakutakura nemagazini maviri.Aya majenari maviri anonzi majenari ekutsigira uye zvakare ndiwo mareferensi emusangano we shaft.Pamusoro pekurongeka kwedimensional, iyo geometric accuracy (kutenderera, cylindricity) yebhuku rinotsigira rinowanzodikanwa.Kune majenari ehuchokwadi hwese, iko kukanganisa kwejometri kunofanirwa kugumira kune dhayamita kushivirira.Kana izvo zvinodiwa zvakakwirira, kushivirira kwakakosha kunobvumirwa kunofanirwa kutsanangurwa pane chikamu chekudhirowa.

3) Kurongeka kwenzvimbo Kubatana pakati pemajenari ekusangana (majenari enhengo dzemotokari dzakaungana) muzvikamu zveshaft zvine chekuita nemagazini ekutsigira chinhu chinowanzodiwa kuti awirirane nenzvimbo yawo.Kazhinji, shaft ine yakajairwa nemazvo, iko kuenderana neruremekedzo rwekumhanya kwejenari retsigiro kazhinji 0.01-0.03 mm, uye iyo yakakwirira-chaiyo shaft i0.001-0.005 mm.Mukuwedzera, iyo mutual positional accuracy ndeyewo coaxiality yemukati uye yekunze cylindrical surfaces, iyo perpendicularity yeaxially positioned end end faces uye axial line, nezvimwe zvakadaro.2, kushata kwepamusoro Zvinoenderana nekurongeka kwemuchina, kumhanya kwekushanda, kushata kwepamusoro zvinodiwa zveshaft zvikamu zvakare zvakasiyana.Kazhinji, kushata kwepamusoro Ra yemagazini inotsigira ndeye 0.63-0.16 μm;kushata kwepamusoro Ra yejenari inofananidzira ndeye 2.5-0.63 μ m.

Iyo tekinoroji yekugadzira 1, kusarudzwa kwezvinhu shaft zvikamu zveshaft zvikamu, Zvikuru zvichibva pasimba, kuomarara, kupfeka kuramba uye maitiro ekugadzira shaft, uye kuyedza hupfumi.
