Cov precision reducers siv los ntawm thoob ntiaj teb kev lag luam neeg hlau yog ib txwm monopolized los ntawm Nyiv. Nyob rau hauv xyoo tas los no, txawm hais tias muaj ntau-tsim RV reducers nyob rau hauv Tuam Tshoj, ob peb domestic neeg hlau tuam txhab uas muag xaiv lawv. Tam sim no, cov reducers nyob rau hauv Suav lag luam feem ntau cia siab rau imports.

Raws li lub tuam txhab tsim hluav taws xob ib txwm muaj, cov khoom lag luam reducer ntawm lub teb chaws Yelemees, Ltalis, Nyiv thiab lwm lub teb chaws yog nyob rau hauv txoj hauj lwm ua lag luam nyob rau hauv cov ntaub ntawv, tsim theem, zoo tswj, precision, zog ceev, kev cia siab thiab kev pab cuam lub neej.
Nyob rau hauv lub tshav pob ntawm mechanical kis tau tus mob, lub reducer yog ib tug nruab nrab ntaus ntawv txuas lub hwj chim qhov chaw thiab lub actuator. Feem ntau, nws siv lub zog khiav ceev ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob sab hauv kom ua tiav lub hom phiaj ntawm deceleration los ntawm cov iav me me ntawm cov khoom siv nkag thiab cov iav loj ntawm cov zis tawm. Thiab xa ntau torque.
Tsav los ntawm txoj kev loj hlob ntawm aerospace, neeg hlau thiab khoom siv kho mob, qhov kev thov rau high-performance precision reducers nrog yooj yim thiab compact qauv, siab kis tau tus mob, tsis muaj suab nrov, thiab ruaj khov kis tau tus mob tau nce, cov uas RV reducers thiab harmonic reducers yog precision reducers. yog ob hom reducers uas hnyav tshaj plaws hauv lub tshuab.
Lub precision reducer yog lub zog xa hluav taws xob uas siv lub iav nrawm hloov pauv kom txo tus naj npawb ntawm cov kiv cua ntawm lub cev muaj zog mus rau qhov xav tau ntawm kev hloov pauv thiab tau txais lub zog loj dua.
▲ Nabtesco reducer
Tam sim no, tsis muaj ntau manufacturers ntawm precision reducers nrog loj-scale thiab txhim khu kev qha kev ua tau zoo nyob rau hauv lub ntiaj teb no, thiab feem ntau ntawm cov lag luam qhia tau nyob rau hauv Nyiv tuam txhab uas muag: Nabtesco's RV reducer account rau txog 60 feem pua, Harmonica's harmonic reducer account rau txog 15. feem pua , Tseem muaj Sumitomo Heavy Industries (SUMITOMO, feem tsis pom). Tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm robotics, qhov kev faib ua feem ntawm daim ntaub ntawv yog yooj yim.
Nabtesco (Nabtesco) yog tsim los ntawm kev sib koom ua ke ntawm ob lub tuam txhab Nyij Pooj, Teijin Seiki thiab Nabok (uas ua rau Nyiv thawj lub qhov rooj tsis siv neeg hauv 1956). Raws li cov chaw tsim khoom ntawm kev tswj hwm cov lus tsa suab thiab cov khoom siv, ob lub tuam txhab tau paub cov thev naus laus zis siab kawg thiab tswj hwm kev lag luam loj hauv lawv cov kev lag luam tshwj xeeb.
Raws li lub ntiaj teb loj tshaj plaws chaw tsim tshuaj paus ntawm precision cycloid reducers, Nabtesco tsim high-kev ua tau zoo reducers, hollow ncej reducers, thiab ib leeg-axis servo actuators thiab controllers.
Cov khoom siv precision tsim los ntawm nws muaj lub zog siab, siab nruj thiab siab dhau ntawm kev thauj khoom muaj peev xwm, thiab tib lub sijhawm muaj qhov siab thiab qis rov qab tshem tawm, thiab tau siv dav hauv satellites, radar antennas, industrial robots, semiconductors thiab vuam tshuab. thiab lwm yam kev lag luam ntawm automation.

Nyiv lub Harmonic Drive Systems Inc. (HDSI luv luv) yog tus thawj coj hauv kev tswj hwm txhua qhov kev txav. Lub Harmonic Drive sib xyaw ua ke sib xyaw ua ke uas tsim los ntawm nws muaj cov yam ntxwv ntawm lub teeb yuag, me me, tsis muaj iav rov qab, thiab muaj peev xwm torque siab. Nws yog dav siv nyob rau hauv ntau yam cutting-edge teb xws li industrial robots, humanoid robots, semiconductor kua siv lead ua khoom siv, photovoltaic khoom, kho qhov muag instruments, thiab precision tshuab cuab yeej.

Txhawm rau txhawm rau txhawm rau txhawm rau txo qis qis qhov chaw uas cov kev sib haum xeeb txo qis tsis tuaj yeem ua tiav, HDSI cov khoom lag luam kuj koom nrog cov precision planetary gearbox hom harmonic reducer Harmonic Planetary. Cov txheej txheem deformation tshwj xeeb ntawm lub nplhaib puab tuaj yeem ua rau lub ntiaj teb iav mesh nrog nws nruj dua, tshem tawm cov backlash, thiab ua tiav qhov kev ua yuam kev ntawm qib precision.

Harmonic tsav reducer yog lub iav kis tau tus mob uas tso siab rau lub tshuab hluav taws xob nthwv dej los tsim kev tswj tau elastic deformation ntawm lub zog hloov tau yooj yim thiab meshes nrog cov iav nruj kom xa cov lus tsa suab thiab lub zog los ntawm qhov pib.
Nyiv lub Sumitomo SUMITOMO yog lub chaw tsim khoom siv tshuab hauv qab Sumitomo Group, yog ib lub tuam txhab loj tshaj plaws hauv ntiaj teb nrog ntau tshaj 400 xyoo dhau los. Tom qab Sumitomo cov khoom tsim thawj hydraulic excavator nrog nws tus kheej thev naus laus zis hauv xyoo 1967, Sumitomo tam sim no ua haujlwm thoob plaws ntiaj teb. Silhouette ntawm hydraulic excavator.
Sumitomo reducer muaj xws li ntau hom reducer, xws li Sumitomo loj helical iav reducer, Sumitomo planetary iav reducer, Sumitomo helical iav reducer, Sumitomo worm iav reducer, thiab lwm yam. Qhov kev txo qis yog qhov loj, kev ua haujlwm siab, tus pin hniav meshing system yog Lub tes tsho-hom dov kev sib txhuam, qhov meshing nto tsis muaj qhov sib txheeb zawv zawg, thiab thawj theem txo qhov ua tau zoo tuaj yeem ncav cuag 94 feem pua.

Raws li ib tug pinnacle ntawm precision machinery kev lag luam, qhov kev kawm pib ntawm lub reducer yog siab heev. RV reducer yog tag nrho ntawm cov khoom siv siab thiab cov iav meshing nrog ib leeg. Precision nrhiav tshuab tso siab heev xav tau.
Feem ntau ntawm kev tshawb fawb thiab kev loj hlob ntawm cov lag luam hauv tsev tau txais cov ntaub ntawv los ntawm kev rov qab engineering, thiab lawv tau paub txog nws tab sis tsis paub vim li cas. Yog li ntawd, txawm hais tias qee qhov kev lag luam hauv tsev tau ua kom muaj kev cuam tshuam loj hauv qib kev, muaj teeb meem hauv kev tshawb fawb thiab kev txhim kho cov khoom siv hauv tsev hauv cov ntsiab lus ntawm kev saib xyuas raug, precision lub neej thiab khoom lub neej. Ntau yam teeb meem ua rau tsis zoo sib xws ntawm cov khoom siv hauv tsev. tsawg reproducibility.
Ntawm qhov tod tes, cov khoom siv rau kev ua thiab tsim cov khoom ntawm lub reducer yog kim heev. Piv txwv li, chav tsev nqi ntawm Megale nto grinder yog ze rau 10 lab yuan. Yog tias tsis muaj kev txhawb nqa ntau lawm, tus nqi amortization ntawm cov cuab yeej yog qhov txaus ntshai heev.
Tus nqi ntawm domestic precision reducers yog siab dua li ntawm cov neeg sib tw txawv teb chaws, tab sis lawv qhov kev ua tau zoo yog qhov phem dua li ntawm lawv cov neeg sib tw. Ntawm chav kawm, qhov muag ntim tsis zoo, thiab nws yog tsis yooj yim sua kom ua tiav kev lag luam ntawm nplai thiab profitability. Yog tias tsis muaj txiaj ntsig, tsis muaj cov khoom siv, yuav tsis muaj peev txheej txaus los ua cov kev txhim kho thev naus laus zis, kev tshawb nrhiav thiab kev tsim kho, thiab yuav tsis muaj txoj hauv kev los tsim kev tswj kom zoo, thiab yuav tsis muaj txoj hauv kev los txhim kho thev naus laus zis thiab kev ua haujlwm.
Tam sim no, muaj ob lub ntsiab ntawm reducers siv nyob rau hauv lub teb ntawm robots, ib tug yog RV reducer, thiab lwm yam yog harmonic reducer. Nyob rau hauv articulated robots, vim hais tias tus RV reducer muaj siab rigidity thiab rotation raug, RV reducer feem ntau muab tso rau ntawm lub hauv paus, lub boom, lub xub pwg nyom thiab lwm yam hnyav loads, thiab harmonic reducer yog muab tso rau ntawm forearm, dab teg los yog tes.
Rau high-precision neeg hlau reducers, Nyiv muaj qhov ua tau zoo tshaj plaws. Tam sim no, 75 feem pua ntawm cov precision reducers nyob rau hauv lub ntiaj teb no neeg hlau kev lag luam yog monopolized los ntawm Nyiv lub Nabtesco thiab HarmonicDrive (feem ntau hu ua RV reducers thiab harmonic reducers nyob rau hauv kev lag luam), xws li ABB, FANUC, reducers ntawm thoob ntiaj teb mainstream neeg hlau manufacturers xws li KUKA yog muab los ntawm ob lub tuam txhab saum toj no.
Raws li kev lag luam sab hauv, ABB, FANUC, Yaskawa, KUKA thiab lwm cov neeg hlau thoob ntiaj teb cov neeg tsim khoom lag luam txhua tus muab kev txo qis los ntawm ob lub tuam txhab Nyij Pooj, thiab lawv muaj kev koom tes nruj heev nrog ob lub tuam txhab, uas yog, thaum siv cov khoom ntawm cov ob lub tuam txhab tsis tuaj yeem siv cov khoom lag luam ntawm lwm lub tuam txhab, txwv tsis pub kev sib koom tes yuav raug txiav.
Cov khoom tseem ceeb yeej ib txwm txwv txoj kev loj hlob sai ntawm Suav robots. Yog tias peb xav tsim kev lag luam kev lag luam ntawm cov neeg hlau, tshem tawm cov kev txwv ntawm cov tuam txhab neeg hlau txawv teb chaws, thiab yeej muaj kev ywj pheej nyob rau hauv kev lag luam ntawm cov neeg hlau, peb yuav tsum ua kom lub hauv paus ntawm kev txo qis hauv cov txheej txheem.
