Ubuchwepheshe obungenalutho be-motor shaft

Iimotoi-shaft ayinalutho, inokusebenza okuhle kokukhipha ukushisa futhi ingakhuthaza ukulula kwe-imoto.Ngaphambili, ama-motor shafts ayeqinile kakhulu, kodwa ngenxa yokusetshenziswa kwe-motor shafts, ukucindezeleka kwakuvame ukugxila ebusweni be-shaft, futhi ukucindezeleka okuphakathi kwakuncane. Ngokuvumelana nezakhiwo zokugoba kanye ne-torsional of mechanics wezinto ezibonakalayo, ingxenye yangaphakathi ye-imotoumphini wawugojiwe ngokufanelekile, futhi kwakudingeka ububanzi obuncane nje obungaphandle ukuze kwandiswe ingxenye engaphandle. I-shaft engenalutho ingahlangabezana nokusebenza okufanayo futhi isebenze njenge-shaft eqinile, kodwa isisindo sayo singancishiswa kakhulu. Phakathi naleso sikhathi, ngenxa yokugoba kwe-imotoshaft, amafutha okupholisa angangena ngaphakathi kwe-motor shaft, akhulise indawo yokukhipha ukushisa futhi athuthukise ukusebenza kahle kokukhipha ukushisa. Ngaphansi kokuthambekela kwamanje kokushaja okusheshayo okungu-800V, inzuzo yamashafu emoto angenalutho inkulu kakhulu. Izindlela zamanje zokukhiqiza zama-hollow motor shafts ikakhulukazi zifaka i-shaft hollowing eqinile, i-welding, kanye nokwakheka okuhlanganisiwe, lapho ukushisela kanye nokwakheka okuhlanganisiwe kusetshenziswa kabanzi ekukhiqizeni.

Ishafti eshicilele egobile itholakala ngokuyinhloko ngokwakhiwa kwe-extrusion ukuze kuzuzwe imbobo yangaphakathi enezitezi, bese ifakwa ngomshini bese ishiselwa ukuze ibe yisimo. Ngokubunjwa kwe-extrusion, izinguquko zomumo wembobo yangaphakathi enesakhiwo somkhiqizo kanye nezidingo zamandla zigcinwa ngangokunokwenzeka. Ngokuvamile, ubukhulu bodonga obuyisisekelo bomkhiqizo bungaklanywa ngaphansi kuka-5mm. Imishini yokushisela ngokuvamile isebenzisa i-butt friction welding noma i-laser welding. Uma kusetshenziswa i-butt friction welding, indawo yelunga le-butt ngokuvamile imayelana ne-3mm welding protrusion. Ngokusebenzisa i-laser welding, ukujula kokushisela ngokuvamile kuphakathi kuka-3.5 no-4.5mm, futhi amandla okushisela angaqinisekiswa ukuthi angaphezu kuka-80% we-substrate. Abanye abahlinzeki bangakwazi ngisho nokuzuza ngaphezu kuka-90% wamandla e-substrate ngokusebenzisa izinyathelo eziqinile zokulawula inqubo. Ngemuva kokuthi ukushiselwa kwe-shaft engenalutho sekuqediwe, kuyadingeka ukwenza ukuhlolwa kwe-ultrasonic noma i-X-ray ku-microstructure kanye nekhwalithi ye-weld yendawo yokushisela ukuze kuqinisekiswe ukuhambisana komkhiqizo.

I-shaft ehlanganisiwe eyenza i-hollow shaft yenziwe ngokuyinhloko izinto zangaphandle endaweni engenalutho, okwenza ingxenye yangaphakathi ikwazi ukuzuza ngokuqondile imbobo yangaphakathi enyathelwe. Njengamanje, i-radial forging kanye ne-rotary forging isetshenziswa kakhulu, futhi imishini ithengwa kakhulu kwamanye amazwe. I-radial forging ijwayelekile emishinini yenkampani ye-FELLS, kuyilapho i-rotary forging ijwayelekile emishinini yenkampani ye-GFM. Ukwakheka kwe-Radial forging ngokuvamile kufinyelelwa ngokusebenzisa izando ezine noma ngaphezulu ezilinganayo ngemvamisa yamagalelo angaphezu kuka-240 ngomzuzu ukuze kuzuzwe ukuguqulwa okuncane kweshubhu elingenalutho neliqondile elingenalutho. Ukwakhiwa kwe-Rotary forging kuyinqubo yokuhlela ngokulinganayo amakhanda esando amaningi endaweni eyindilinga ye-billet. Ikhanda lesando lizungeza i-eksisi ngenkathi lenza i-radial high-frequency forging on the workpiece, yehlisa usayizi wesigaba esiphambanayo se-billet futhi inwebe nge-axially ukuze kutholwe ucezu lokusebenza. Uma kuqhathaniswa namashafu aqinile endabuko, izindleko zokukhiqiza izigxobo ezihlanganisiwe ezakhiwe zizokhuphuka cishe ngo-20%, kodwa isisindo samashafu ezimoto ngokuvamile sizokwehliswa ngo-30-35%.
