Raws li cov ntsiab lus tseem ceeb ntawm kev lag luam neeg hlau, precision reducers rau cov neeg hlau xav tau cov yam ntxwv xws li cov hlua txuas luv luv, ntim me me, siab zog, lub teeb yuag, thiab tswj tau yooj yim piv rau universal reducers.
Muaj ob lub ntsiab ntawm cov reducers siv dav hauv cov neeg hlau sib txuas: RV reducers thiab harmonic reducers.
Lub hauv paus ntsiab lus, qhov zoo thiab qhov tsis zoo ntawm RV reducer thiab harmonic reducer:
RV reducer:
Siv rau peb lub pob qij txha ntawm ob txhais ceg, lub duav, thiab lub luj tshib ntawm cov neeg hlau nrog lub siab torque, thiab rau cov neeg hlau uas muaj cov khoom hnyav, 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 nyob hauv lawv cov txheej txheem machining thiab sib dhos. RV reducers muaj zog dua qaug zog, nruj, thiab lifespan, tsis zoo li harmonic drives, uas ua rau txo cov suab raug lub sij hawm. Lawv drawbacks yog hnyav hnyav thiab loj tag nrho qhov ntev.
Harmonic reducer:
Siv rau kev lag luam neeg hlau nrog cov khoom me me lossis cov neeg hlau loj nrog ntau lub shafts thaum kawg, harmonic reducer yog ib hom kev sib kis sib kis, uas suav nrog kev sib haum xeeb accelerator thiab harmonic reducer. Harmonic reducers feem ntau suav nrog: lub log nruj, lub log hloov tau yooj yim, cov kabmob, thiab cov tshuab hluav taws xob nthwv dej, txhua yam yog qhov tseem ceeb. Ntawm lawv, tus naj npawb ntawm cov hniav ntawm lub log nruj me ntsis ntau dua li ntawm lub log hloov tau yooj yim. Cov yam ntxwv ntawm harmonic reducers siv nyob rau hauv me me robots yog me me, lub teeb yuag, siab load-bearing muaj peev xwm, siab motion precision, thiab loj ib theem kis tau tus mob piv.
Ob leeg yog meshing nrog cov hniav me me sib txawv, tab sis qhov sib txawv yog tias lub iav tseem ceeb hauv kev sib haum xeeb yog hloov tau thiab yuav tsum tau rov ua kom nrawm nrawm dua, yog li nws yog qhov tsis yooj yim, nrog rau cov kabmob muaj peev xwm thiab lub neej ntev. RV feem ntau siv cycloidal pinwheels, thaum harmonics siv los siv involute hniav profiles. Qee cov tuam txhab lag luam tam sim no siv ob chav arc hniav profiles, uas yog ntau tshaj tshaj li involutes.
Ob lub loj loj ntawm kev ceev reducers yog Nabtesco thiab Harmonica Drive, uas yuav luag monopolize lub ntiaj teb no neeg hlau ceev reducers. Ob hom reducers muaj qhov tseeb machining ntawm qib micrometer, ua rau nws nyuaj rau kev ua tiav kev ntseeg siab thaum lub sijhawm ntau lawm ib leeg, cia ib leeg ua haujlwm siab ntawm ntau txhiab kiv puag ncig, thiab tseem muaj lub neej ntev.
Lub harmonic reducer yog tsim los ntawm plaub yam tseem ceeb: "lub log hloov tau, lub tshuab hluav taws xob nthwv dej, lub log nruj, thiab cov kabmob".
Lub sab nraud ntawm lub log hloov tau me ntsis me dua li lub puab kab uas hla ntawm lub log nruj, thiab feem ntau lub log hloov tau muaj 2 cov hniav tsawg dua lub log nruj. Cov duab elliptical ntawm lub tshuab hluav taws xob nthwv dej txiav txim siab tias cov ntsiab lus ntawm cov hniav sib txuas ntawm lub log hloov tau yooj yim thiab lub log tsis sib xws tau muab faib rau ob sab ntawm qhov nruab nrab ntawm lub ellipse. Thaum lub sij hawm kev sib hloov ntawm lub tshuab hluav taws xob nthwv dej, qhov sib cuag ntawm cov iav hloov tau thiab cov hniav khov kho cov hniav pib mesh. Lub tshuab hluav taws xob nthwv dej tig 180 degrees clockwise, thiab lub log hloov tau zoo sib npaug rau lub log nruj tig rov qab los ntawm ib tus hniav sib txawv. Ntawm ob qhov 180 degree symmetrical qhov chaw, ntau dua 30 feem pua ntawm tag nrho cov hniav mesh ib txhij, uas kuj tsim kom muaj kev sib kis siab.
Piv nrog rau kev sib haum xeeb reducers, RV kis tau tus mob yog ib yam tshiab ntawm kev sib kis, uas yog tsim los ntawm ib txwm koob pendulum planetary kis tau tus mob. Nws tsis tsuas yog kov yeej qhov tsis txaus ntawm cov koob pendulum kis tau tus mob, tab sis kuj muaj cov txiaj ntsig zoo xws li qhov me me, lub teeb yuag, qhov sib kis loj loj, kev ua haujlwm ntev, kev ruaj khov, kev ua haujlwm siab, thiab kev sib kis tau zoo.
RV reducers yog tsim los ntawm cycloidal pinwheels thiab planetary kev txhawb nqa, thiab yog dav siv nyob rau hauv industrial robots, tshuab cuab yeej, cov cuab yeej kuaj mob, satellite txais systems, thiab lwm yam teb vim lawv qhov zoo xws li me me, muaj zog tiv thaiv, siab torque, siab. positioning raug, tsis tshua muaj kev vibration, thiab loj txo qhov sib piv.
Lub vaj tse thiab cycloidal iav ntawm RV reducer yog kis los ntawm cov khoom hlau, yog li muaj peev xwm thauj khoom muaj zog. Lub log hloov tau yooj yim ntawm harmonic reducers tuaj yeem ua tsis tu ncua kom xa cov torque, uas txiav txim siab lub peev xwm ntawm kev sib haum xeeb kom tiv taus lub zog loj thiab cuam tshuam, yog li lawv feem ntau siv nyob rau hauv pem hauv ntej kawg.
Qhov zoo thiab qhov tsis zoo ntawm ob qho tib si RV thiab harmonic reducers
Lub harmonic reducer muaj ib tug yooj yim thiab compact qauv, haum rau daim ntaub ntawv nrog miniaturization, tsawg thiab nruab nrab loads.
RV reducers muaj qhov zoo rigidity, muaj zog cuam tshuam tsis kam, ruaj khov kis tau tus mob, thiab siab raug, ua rau lawv haum rau cov ntawv thov nrog nruab nrab mus rau hnyav loads. Txawm li cas los xij, RV reducers yuav tsum tau xa cov torque loj, tiv taus qhov cuam tshuam ntau dhau, thiab ua kom lub neej ua haujlwm tau zoo. Yog li ntawd, cov txheej txheem sib txawv ntawm qhov chaw yog siv rau hauv kev tsim, ua cov txheej txheem tsim khoom thiab kev tswj tus nqi nyuaj. Tsis muaj elastic deformation load-bearing Cheebtsam hauv RV reducer, yog li nws tuaj yeem tiv taus qee qhov ntawm lub zog. Cov kabmob ntawm RV reducer yog nws qhov kev sib txuas tsis muaj zog, thiab nws yooj yim kom dhau ntawm cov kabmob muaj peev xwm txwv thaum raug quab yuam, ua rau muaj qhov txawv txav lossis tawg 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 ceev.
