Kev Kawm Cov Hom Phiaj
- Tiag tiag-ntiaj teb rotary servo tshuab poob luv ntawm kev ua tau zoo tshaj plaws vim kev txwv kev ua haujlwm.
- Ntau hom Rotary Servomotors tuaj yeem muab cov txiaj ntsig rau cov neeg siv, tab sis txhua qhov muaj kev sib tw lossis kev txwv.
- Direct Drive Rotary Servomotors muaj kev ua tau zoo tshaj plaws, tab sis lawv kim dua cov gearmotors.
Rau kaum xyoo, geared servomotors tau yog ib qho ntawm cov cuab yeej feem ntau hauv kev lag luam Toolbox. Geared sevromotors muaj qhov muab tso tawm, kev tshaj tawm, cua tshuab hluav taws xob, tshuab hluav taws xob, zawm cov ntawv thov ntawm lub servomotor rau lub nra. Qhov no nce cov lus nug: yog cov keared servomotor Qhov kev xaiv zoo tshaj plaws rau cov lus tsa suab paj nruag teb, lossis puas muaj kev daws teeb meem zoo dua?
Hauv lub ntiaj teb zoo tag nrho, lub zog teb rotary yuav muaj lub zog thiab nrawm nrawm uas phim daim ntawv thov yog li lub cev muaj zog los yog tsis nyob hauv qab. Kev sib xyaw ua ke ntawm lub cev muaj zog, kev sib kis tau, thiab thauj khoom yuav tsum muaj qhov tob tob tirional txhav thiab xoom backlash. Hmoov tsis zoo, tiag tiag ntiaj teb rotary servo tshuab poob luv ntawm qhov zoo tagnrho rau kev sib txawv.
Nyob rau hauv ib txwm Servo System, Backlash tau txhais raws li kev ploj ntawm cov lus tsa suab ntawm lub cev muaj zog thiab thauj khoom los ntawm kev thev naus laus zis; Qhov no suav nrog cov lus tsa suab poob thoob plaws gearboxes, siv tawv, saws, thiab couplings. Thaum lub tshuab siv lub zog rau, lub load yuav ntab ib qhov chaw hauv nruab nrab hauv nruab nrab ntawm kev thev naus laus zis (daim duab 1a).
Ua ntej thauj nws tus kheej yuav raug txav los ntawm lub cev muaj zog, lub cev muaj zog yuav tsum tau tig mus rau txhua qhov slack uas muaj nyob hauv cov khoom sib kis (daim duab 1b). Thaum lub cev muaj zog pib decelerate thaum kawg ntawm kev txav, lub chaw thauj khoom yuav ua tau dhau lub zog ua haujlwm raws li lub zog thauj khoom dhau ntawm lub cev muaj zog.
Lub cev muaj zog yuav tsum tau rov qab siv cov slack nyob rau hauv kev coj ua ntej thov kom muaj zog rau lub thauj mus los kom decelerate nws (daim duab 1c). Qhov kev poob ntawm cov lus tsa suab yog hu ua Backlash, thiab ib txwm ntsuas hauv arc-feeb, sib npaug rau 1 / 60th ntawm ib degree. Gearboxes tsim rau siv cov servos hauv kev siv cov ntawv thov feem ntau muaj cov specollash specifications li 3 txog 9 arc-feeb.
Tiffional txhav yog qhov tsis kam mus sib ntswg ntawm lub cev muaj zog, thiab thauj khoom hauv kev teb rau daim ntawv thov ntawm lub zog. Lub infinitated txhav hnyav yuav kis lub torque rau lub nra uas tsis muaj dav deflection txog lub axis ntawm kev sib hloov; Txawm li cas los xij, txawm tias cov hlau khov kho hlau ncej yuav twist me ntsis hauv qab lub nra hnyav. Qhov ntau ntawm deflection txawv nrog lub torque ua ntawv thov, cov khoom siv ntawm cov khoom xa rov qab, thiab lawv cov duab; Kev ua tiav, ntev, nyias qhov chaw yuav ntswj ntau dua li luv luv, cov rog. Qhov no tsis kam mus sib ntswg yog dab tsi ua rau coil springs ua haujlwm, raws li compressing lub caij nplooj ntoo hlav txhua qhov tig ntawm cov xaim hlau me ntsis; fatter xaim ua rau lub caij nplooj ntoo hlav stiffer. Txhua yam tsawg dua tsis tshua muaj neeg ua rau lub zog ua rau lub caij nplooj ntoo hlav, txhais tau tias lub zog muaj zog sib hloov.
Thaum ua ke ua ke, finite torsional txhav thiab backlash tuaj yeem thuam cov kev ua tau zoo ntawm kev ua haujlwm servo. Backlash tuaj yeem qhia qhov tsis paub tseeb, raws li lub zog encoder qhia txog txoj hauj lwm ntawm lub cev muaj zog, tsis pub nyob qhov twg cov backlash tau tso cai rau lub thauj mus los. Backlash kuj tseem qhia txog qhov teeb meem raws li cov khub niam txiv thauj khoom thiab tsis muaj kev sib cav sib luag thaum lub nra thiab lub cev muaj zog rov qab cov kwvtij txheeb ze. Ntxiv nrog rau backlash, finite torsional stiffness Khw muag khoom los ntawm kev hloov qee lub zog lub zog ntawm lub cev muaj zog thiab thauj mus rau hauv lub zog muaj peev xwm, tso nws tom qab. Qhov kev ncua lub zog qeeb no ua rau thauj khoom oscillation, ntxias txoj kev siv hluav taws xob uas siv tau thiab tsis zoo rau lub luag haujlwm thiab kev sib txuas lus ntawm Servo system. Hauv txhua qhov xwm txheej, txo qis backlash thiab nce qhov txhav ntawm lub system yuav ua kom muaj kev ua tau zoo rau servo thiab yooj yim kho.
Rotary Axis Servomotor Cov Chaw Tsim Kho
Feem ntau cov kev teeb tsa kev teeb tsa Axis Axis yog ib lub servorotor nrog lub generTber rau txoj haujlwm tawm tswv yim thiab nrawm ntawm lub cev muaj zog thiab nrawm ntawm lub nra. Lub iav yog ib qho khoom siv hluav taws xob tas li uas yog cov neeg kho tshuab ntawm lub tshuab hloov pauv rau kev thauj khoom sib txuam.
Cov khoom kho vaj tse txhim kho kev siv cov kev pabcuam ua haujlwm ncaj qha Rotary Servomotor, uas tshem tawm cov khoom xa tuaj los ntawm kev thauj ncaj qha rau lub cev muaj zog. Whereas lub iav xov tooj siv siv txuas rau qhov sib txuas me me, tsav cov txheej txheem loj dua, khawm ncaj qha rau kev thauj khoom ncaj qha mus rau qhov loj dua rotor flange. Qhov kev teeb tsa no tshem tawm backlash thiab zoo heev nce torsional txhav txhav. Lub Ncej Siab Rov Qab thiab High Torque Cov Motors Ncaj Nraim Nkaus Tiaj Tus Torque thiab cov ceev cov yam ntxwv ntawm lub iav sib piv nrog 10: 1 lossis siab dua.
