Irobhothi likaTesla's humanoid Optimus isebenzisa i-1:14izikulufo ze-roller zeplanethi. NgoSuku lwe-Tesla AI ngo-Okthoba 1, i-humanoid Optimus prototype yasebenzisa izikulufu zamarola weplanethi nezinciphisi ze-harmonic njengesixazululo esihlangene somugqa ongasikhetha. Ngokokunikezwa okukuwebhusayithi esemthethweni, i-Optimus prototype isebenzisa izinciphisi eziyi-14 ze-harmonic kanye nezikulufu eziyi-14 zeplanethi. Iizikulufo ze-roller zeplanethizihehe ukunakwa okusabalele emakethe njengoba umklamo weyunithi yokudlulisa udlule obekulindelwe kulokhu kwethulwa.
Umfanekiso 1: I-Optimus ene-planetary roller screw njengenketho
Isizukulwane esisha samagatsha e-linear drive,izikulufu zeplanethi,sezivele zisetshenziswa emikhakheni enembayo ephezulu emhlabeni wonke, ehlanganisa ukunyakaza kwe-helical kanye neplanethi enezidingo eziphezulu zokusebenza jikelele. Uma kuqhathaniswaizikulufo zebholangosayizi ofanayo,izikulufo ze-roller zeplanethizibonakala “ngomsebenzi osindayo, ukusebenza kahle okuphezulu, isivinini kanye nempilo ende” futhi zisetshenziswe ngezinga elikhulu ezimakethe zamasosha aphesheya kwezilwandle kanye nezimakethe zomphakathi ezisezingeni eliphezulu.Izikulufu zamarola eplanethizisetshenziswa ku-aerospace, izikhali, amandla enuzi nezinye izinhlelo zokusebenza ezikhethekile. Isibonelo, igiya lokuhlala indiza, iziqalisi zokumisa indiza enophephela emhlane, njll. Ngaphezu kwalokho, kunesidingo samathuluzi omshini, izinhlelo ze-ABS zezimoto, amakhemikhali kaphethiloli nezinye izinhlelo zokusebenza emakethe yomphakathi. Ngokwezibalo, ngo-2021 i-planeetary roller roller screw 230 million US dollars, eminyakeni emihlanu ezayo izinga lokukhula elihlanganisiwe lika-5.7%, irobhothi le-humanoid noma lifaka amathuba amaningi embonini.
Indawo yemakethe: isilinganiso somhlaba wonke sama-US$330 wezigidi ngo-2025, ikusasa lingase ligcwele amathuba amaningi
Ukungena kwesikulufu seplanethi yeplanethi kuyaqhubeka nokukhula:
► Kweisikulufu sebholaukushintshwa: akukho mbuyiseli webhola odingekayo, ukugwema izinkinga zomsindo. Ngaphezu kwalokho, izikulufu ze-roller zeplanethi zinamaphuzu amaningi okuzibandakanya, zinikeza ukuqina okungcono kanye nomthamo wokuthwala umthwalo ezimeni zokusebenza ezinzima. Ngamathuluzi emishini nakweminye imikhakha,izikulufo ze-roller zeplanethizihlale zivuna ngenxa yobude bazo obuncane bokuhola kanye nemithwalo ephakeme; kumarobhothi, i-automation namanye amasilinda kagesi, amukelwa kancane kancane ngenxa yokuphendula kwawo okusheshayo, njll.
► Enye indlela yokudluliswa kwehydraulic: ukudluliswa kwamanzi kudinga amaphampu namavalvu ama-hydraulic, njll. Ngokwamukelwa kweizikulufo ze-roller zeplanethi, ivolumu ephelele iyancishiswa, izinkinga zokuvuza kwamafutha ziyazungezwa futhi ukuhlakazwa nokugcinwa kulula. Emkhakheni wemishini yokwakha, ngokusebenzisa isikulufu se-roller planetary ukuze sithathe indawo yohlelo olukhulu lomthwalo we-hydraulic, singabona ngempumelelo isilawuli se-elekthronikhi, kulula ukusishintsha. Emkhakheni wezimoto zamandla amasha, amabhuleki asebenza ngogesi athathelwa indawo ama-electro-mechanical braking systems (EMB) ukuze aphendule ngokushesha.
Ngokocwaningo lwemakethe ye-Persistence, imakethe yomhlaba wonke ye-roller screw kulindeleke ukuthi ikhule ku-CAGR ka-4.8% iye ku-$230 million kusukela ngo-2012 kuya ku-2020, noma cishe i-RMB 1.52 billion. Kusukela ngo-2020 kuye phambili, ngesidingo esikhulayo semithombo yamandla emisha, ucwaningo lwemakethe ye-Persistence lulindele ukuthi imakethe ikhule ku-CAGR ka-5.7% ukusuka ngo-2020 kuya ku-2025 ukuze ifinyelele ezigidini ezingama-330 zamaRandi, noma cishe ama-RMB 2.01 billion.
Ngokuphendula ezindaweni ezihlukene zohlelo lokusebenza, izinhlobo ezine ezengeziwe zamagatsha okwakhiwa kwezikulufu zeplanethi yeplanethi zithathwe ohlotsheni olujwayelekile:
► Uhlobo lokuhlehla: i-nati njengelungu elisebenzayo, isikulufa njengelungu eliphumayo, ayikho indandatho yegiya yangaphakathi. Inzuzo enkulu ukubumbana kanye nokusetshenziswa ezimeni ezincane zomsebenzi we-stroke.
► Ukujikeleza kabusha: indandatho yangaphakathi iyasuswa futhi ukubuyisela (ukwakhiwa kweringi yekhamera) kuyengezwa, i-roller ingajikeleza ngaphakathi kwentongomane isonto elilodwa bese ibuyela endaweni yayo. Ngokwandisa inani lezintambo, inomthamo wokuqina ophakeme futhi isetshenziswa kumishini yezokwelapha, amathuluzi okusebenza ngokunemba, njll.
► Uhlobo lwendandatho yokuthwala: ukwandisa igobolondo, isembozo sokugcina, ama-cylindrical roller bearings nezinye izingxenye, ngcono kakhulu umthamo womthwalo, osetshenziselwa imishini esindayo, i-petrochemical kanye nezinye izinkambu, izindleko zokukhiqiza ziphezulu.
► Uhlobo oluhlukile: i-roller ihlukaniswe ngesakhiwo se-ring groove, susa iringi yegiya yangaphakathi, esebenza ekudluliseni izikhathi ezinkulu. Kodwa ngesikhathi sokunyakaza, imicu izoshelela, igqoke kalula uma kwenzeka umthwalo omkhulu.
I-USA njengamanje iyizwe elifunwa kakhuluizikulufo ze-roller zeplanethiemhlabeni wonke, kulandele iJalimane ne-UK, izifunda ezintathu zihlangene zenza ama-50% emakethe iyonke. U-Tesla ubheke ngabomvu amarobhothi e-humanoid ayisigidi, noma alethe amathuba amaningi. I-2022 Tesla AI Day, uMusk uthemba ukuzuza ukuthengiswa okukhulu kwamarobhothi e-humanoid phakathi neminyaka engu-3-5, sikholelwa ukuthi amarobhothi e-humanoid kulindeleke ukuthi afake umoya wokuthuthukiswa kwezimboni.izikulufo ze-roller zeplanethi.
Isikhathi sokuthumela: May-26-2023
