Lub hauv paus ntsiab lus, qhov zoo thiab qhov tsis zoo ntawm RV reducer thiab harmonic reducer
RV reducer:
RV yog siv rau peb cov pob qij txha ntawm lub duav thiab lub luj tshib ob txhais ceg ntawm cov neeg hlau nrog lub zog loj, thiab rau cov neeg hlau uas muaj cov khoom loj, RV yog siv rau thawj, thib ob thiab thib peb axes. Piv nrog rau kev sib haum xeeb reducers, tus yuam sij rau RV reducers yog nyob rau hauv kev siv tshuab thiab sib dhos tshuab. RV reducer muaj zog dua qaug zog, nruj thiab lifespan. Tsis zoo li kev sib kis ntawm kev sib raug zoo, qhov tseeb ntawm kev txav mus los yuav raug txo qis thaum lub sijhawm siv nce ntxiv. Nws qhov tsis zoo yog qhov hnyav hnyav thiab qhov loj me.

Harmonic reducer:
Siv rau kev lag luam neeg hlau nrog cov khoom me me lossis qhov kawg axes ntawm cov neeg hlau loj, kev sib haum xeeb reducer yog ib hom kev sib kis sib kis. Cov cuab yeej sib txuas sib txuas muaj xws li lub suab sib haum xeeb thiab lub suab sib haum xeeb. Lub harmonic reducer feem ntau muaj xws li: nruj spline, flexspline, bearing thiab yoj generator, tag nrho plaub ntawm uas yog indispensable. Ntawm lawv, tus naj npawb ntawm cov hniav ntawm cov txha hniav laus yog me ntsis loj dua li ntawm flexspline. Cov yam ntxwv ntawm kev sib haum xeeb reducer rau cov neeg hlau me me yog qhov me me, lub teeb yuag, muaj peev xwm thauj khoom loj, muaj peev xwm txav tau siab, thiab qhov loj ntawm ib-theem kis tau tus mob.

Ob leeg mesh nrog me me hniav sib txawv. Qhov txawv yog tias lub iav tseem ceeb hauv kev sib haum xeeb yog hloov tau. Nws yuav tsum tau rov ua kom muaj kev kub ceev deformation, yog li nws yog qhov tsis yooj yim thiab tsis muaj peev xwm thauj khoom thiab kev pabcuam lub neej. RV feem ntau siv cycloidal pinwheels. Harmonics siv los siv cov hniav hniav. Tam sim no qee cov tuam ntxhab siv ob npaug arc hniav duab. Cov hniav zoo li no yog ntau tshaj li involute.
Ob tug loj ntawm reducers yog Nabtesco thiab Hamonica Drive. Lawv yuav luag monopolize lub ntiaj teb neeg hlau reducers. Ob leeg ntawm no reducers muaj micron-theem ua qhov tseeb. Nws yog ib qho nyuaj rau ua tiav kev ntseeg siab nyob rau hauv lub loj ntau lawm theem, cia nyob ib leeg high-ceev kev khiav hauj lwm ntawm ntau txhiab revolutions, thiab lub neej ntev.
Lub harmonic reducer muaj plaub yam tseem ceeb: flexspline, yoj generator, rigid spline, thiab bearing.
Sab nraud txoj kab uas hla ntawm flexspline yog me ntsis me dua lub puab txoj kab uas hla ntawm lub rigid spline, thiab feem ntau cov flexspline muaj 2 cov hniav tsawg dua cov txhav spline. Cov duab elliptical ntawm lub tshuab hluav taws xob nthwv dej txiav txim siab tias cov ntsiab lus ntawm cov hniav sib txuas ntawm flexspline thiab cov kab nrib pleb yog faib rau ob sab ntawm qhov nruab nrab ntawm lub ellipse. Thaum lub sij hawm sib hloov ntawm lub tshuab hluav taws xob nthwv dej, qhov chaw sib cuag ntawm lub flexspline thiab cov hniav khov kho cov hniav pib mesh. Rau txhua txhua 180 degree clockwise kev sib hloov ntawm lub yoj generator, lub flexspline yog sib npaug rau ib tug counterclockwise kev sib hloov ntawm lub txhav spline nrog ib tug hniav tooj sib txawv. Ntawm ob qhov chaw 180 degree symmetrical, ntau dua 30% ntawm tag nrho cov hniav tau koom nrog tib lub sijhawm, uas tseem ua rau nws txoj kev sib kis tau zoo.
Piv nrog rau kev sib haum xeeb reducers, RV kis tau tus mob yog ib qho kev sib kis tshiab. Nws yog tsim los ntawm cov tsoos pin-pendulum planetary kis tau tus mob. Nws tsis tsuas yog kov yeej qhov tsis txaus ntawm kev sib kis tus pin-pendulum, tab sis kuj muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, Nws muaj cov txiaj ntsig zoo xws li kev sib kis loj, lub neej ntev, qhov tseeb ruaj khov, kev ua haujlwm siab, thiab kev sib kis tau zoo. .

RV reducer yog tsim los ntawm cycloidal pinwheel thiab planetary bracket. Nws yog dav siv nyob rau hauv industrial robots, tshuab cuab yeej, cov cuab yeej kho mob thiab ntau lwm yam zoo vim nws qhov me me, muaj zog cuam tshuam tsis kam, loj torque, siab positioning raug, me me vibration, thiab loj txo piv. Cov khoom siv kuaj, satellite txais tshuab thiab lwm yam kev lag luam.
Lub vaj tse thiab cycloidal pinwheel ntawm RV reducer yog tsav los ntawm cov khoom hlau, yog li lawv muaj peev xwm thauj khoom muaj zog. Lub flexspline ntawm lub harmonic reducer tuaj yeem tsis tu ncua deform kom xa torque. Qhov no txiav txim siab tias lub harmonic reducer muaj peev xwm tiv taus lub zog loj thiab cuam tshuam, yog li nws feem ntau yog siv rau pem hauv ntej kawg.

Qhov zoo thiab qhov tsis zoo ntawm RV reducer thiab harmonic reducer
Lub harmonic reducer muaj ib tug yooj yim thiab compact qauv thiab yog haum rau miniaturization, tsawg thiab nruab nrab load daim ntaub ntawv.
RV reducer muaj zoo rigidity, muaj zog cuam tshuam tsis kam, ruaj khov kis tau tus mob thiab siab precision, thiab yog haum rau nruab nrab thiab hnyav load daim ntaub ntawv. Txawm li cas los xij, RV reducer yuav tsum xa cov torque loj thiab tiv taus qhov cuam tshuam loj dhau los ua kom lub neej ua haujlwm tau zoo. Tus tsim siv ib tug kuj complex over-positioning qauv, uas ua rau kev tsim khoom thiab kev tswj tus nqi nyuaj. Tsis muaj elastically deformed kev nyuaj siab Cheebtsam nyob rau hauv lub RV reducer, yog li nws muaj peev xwm tiv taus ib qho torque. Cov kabmob ntawm RV reducer yog nws qhov txuas tsis muaj zog. Thaum siv quab yuam, nws yog ib qho yooj yim kom dhau lub bearing kev nyuaj siab txwv thiab ua rau txawv txav los yog rupture ntawm cov kabmob. Qhov teeb meem no tseem ceeb dua thaum lub sijhawm ua haujlwm siab, yog li qhov ntsuas torque ntawm RV reducer txo qis nrog kev nkag siab ceev.

Puas muaj kev hloov pauv kev sib raug zoo ntawm reducers?
kev pom zoo:
RV reducer muaj zog qaug zog ntau dua, nruj thiab lifespan tshaj li kev sib txuas lus sib haum xeeb feem ntau siv hauv cov neeg hlau, thiab qhov tseeb backlash yog qhov ruaj khov. Tsis zoo li kev sib kis ntawm kev sib raug zoo, qhov tseeb ntawm cov lus tsa suab yuav txo qis thaum siv sij hawm nce. Yog li ntawd, high-precision neeg hlau kis tau tus mob nyob rau hauv ntau lub teb chaws feem ntau siv RV reducers. Yog li ntawd, RV reducers muaj ib tug nyiam maj mam hloov harmonic reducers nyob rau hauv advanced neeg hlau kis tau tus mob.
Cov khoom no muaj kev hloov pauv kev sib raug zoo ntawm qee cov qauv, tab sis cov khoom siv no tsuas tuaj yeem ua tiav ib nrab hloov. Feem ntau, nws yog ib qho nyuaj los hloov ntau hom reducers. Piv txwv li, nyob rau hauv cov nqe lus ntawm ceev piv, qhov ceev ratios ntawm harmonic thiab RV yog ntau npaum li cas loj tshaj cov ntiaj chaw, yog li ntawd lub me me speed ratio teb yog dominated los ntawm cov ntiaj chaw. Tau kawg, qhov sib piv ntawm lub ntiaj teb ceev tuaj yeem ua kom loj dua, tab sis nws nyuaj rau hloov cov kev sib haum xeeb thiab RV. Piv txwv li, nyob rau hauv cov nqe lus ntawm rigidity, lub rigidity ntawm planetary thiab RV yog zoo dua li ntawm harmonics. Nyob rau hauv cov kev siv uas muaj kev cuam tshuam rigidity, nws yog ib qho nyuaj rau harmonics ua tau zoo.
Tus yam ntxwv ntawm harmonic reducer yog tias nws yog lub teeb thiab me me, uas yog qhov nyuaj rau lub ntiaj teb thiab RV kom ua tiav hauv qhov no. Yog li ntawd, ntau hom reducers tsuas yog hloov tau qee qhov, tab sis nws tsis muaj tseeb rau ib yam khoom los hloov lwm yam khoom.
Opposition point of view:
Ntau hom reducers tsis tuaj yeem hloov ib leeg, tab sis muaj kev sib raug zoo.
Ob qhov kev sib kis, RV thiab kev sib haum xeeb, yog qhov sib ntxiv, tab sis nws tsis txiav txim siab txog kev tsim cov kev sib tw hauv zos hauv kev siv nruab nrab thiab qis qis tom qab kev tsim qauv tsim kom zoo thiab kev tsim cov txheej txheem kev ua tiav.
