Dab tsi cov txheej txheem kev kho mob yog siv rau servo motors?
Hav! Ntau yam automation engineers feem ntau fim qhov teeb meem no thaum xaiv SERVO TSAVS: "Vim li cas qee tus servo Fullors tuav cov phiaj xwm ua kom muaj txiaj ntsig tom qab peb xyoos hauv cov khoom noj ua haus, thaum lwm tus muaj xeb tom qab ib xyoos hauv ntug hiav txwv ib puag ncig?" Qee qhov kev xav tias "Kev Kho Mob Hauv Kev Kho Mob tsuas yog thov cov xim," kev cuam tshuam tseem ceeb rau ib puag ncig thiab kev muaj zog lifesp. Lwm tus ntseeg tias "cov txheej txheem nyuaj dua yog qhov zoo dua," tsis xav txog qhov sib txawv ntawm ntau yam (hauv tsev, ncej). Nyob rau hauv kev muaj tiag, servo lub cev muaj zog nto kev kho mob yog qhov yuav tsum tau "sib xyaw {2} {{3} Raws kev tsim." Piv txwv li, cov txheej txheem rwb thaiv tsev tsis muaj tseeb ntawm cov stator core yuav ua rau kev kho lub cev muaj zog ntawm lub cev muaj zog hnav ris tsho hnav. Niaj hnub no, peb yuav tshem tawm cov txheej txheem kev kho kom zoo rau SERVO TSAVCov Cheebtsam tseem ceeb thiab xaiv cov kev xaiv rau kev ua haujlwm sib txawv, pab koj tag nrho cov txuj ci tseem ceeb no.
Ua ntej, nkag siab: Tus nqi tseem ceeb ntawm servo lub cev muaj zog nto kho {}} dua "
Servo lub cev muaj zog deg kho cov kev kho mob tsis yog ib qho "anti {{morraig nrho" muaj nuj nqis} kev yoog, thiab kev ua tiav kev ua tau zoo, thiab lub neej kev txuas ntxiv. " Cov txheej txheem txheej txheem rau cov khoom sib txawv ntawm cov cheeb tsam sib txawv.
1. Tus nqi 1: Kev tiv thaiv ib puag ncig - tiv taus corrosion hauv kev mob nyuaj
Servo Motors nquag khiav haujlwm hauv cov chaw muaj plua plav, lossis ib puag ncig uas muaj plua plav ua qhov "thawj kab ntawm kev tiv thaiv":
- Kev tiv thaiv corrosion:Tiv thaiv cov hlau ua vaj tsev xws li cov tsev nyob ntawm noo noo thiab acidic / alkaline media, tiv thaiv cov khoom muaj zog los yog ua haujlwm tso dag.
2. Tus nqi 2: Kev ntseeg tau ua tiav -} Khaws cov haujlwm tseem ceeb
Cov kev kho deg yuav tsum ua kom haum nrog SERVO TSAVs '"precision thiab teb" yuav tsum tau ua kom tsis txhob muaj kev nyuaj siab los ntawm cov txheej txheem tsis raug:
Rwb thaiv tsev kom paub tseeb:Rwb thaiv thaiv cov txheej txheem ntawm stator cores thiab windings yuav tsum muaj rwb thaiv tsev siab (ntau dua los yog sib npaug los yog sib npaug
Kev ntsuas cua sov disspipation: kev ua vaj tsev nyob thiab stator tseem ceeb los tiv thaiv kev ua kom muaj zog ntau dhau los ntawm kev ua kom muaj zog ntau dhau los ntawm kev txo cov nyiaj los ntawm kwv yees li 10%);
Kev yoog kev hloov: Kev sib txhuam coefficient (0.1 - 0.2) ntawm lub cev muaj zog los txo cov hnav thaum tiv thaiv cov kabmob qis.
3. Tus nqi 3: ncua lub neej - txo tus nqi ntawm cov tswv cuab
Hwm nto kho mob tseem ceeb dua kev txij nkawm txij nkawm - PUB DAWB:
Cov txheej txheem tsav nrog cov qauv txheej txheem yuav xav tau kev pabcuam txhua 1-}}} Cov motors noo nyob twj ywm rust-ag-dawb rau 3-5 xyoos;
Ua raws li siab - kub txheej txheem ntawm cov stator windings tiv thaiv kev laus zog tiv thaiv kom npau taws, txuas ntxiv lub cev muaj zog ntawm 5 mus rau 8 xyoo.
Thib ob, txheej txheem kev kho kom zoo rau SERVO TSAVCore Components: Component-by-Component Breakdown
Cov servo tsav lub tsev, stator, rotor, thiab qev ua haujlwm sib txawv, xav tau cov kev saib xyuas cov txheej txheem rau txhua tus.
1. Tsev:Hais txog "corrosion tawm tsam + cua sov dissipation," nrog cov txheej txheem hloov pauv raws li kev ua haujlwm
Cov tsev lub cev muaj zog yog feem ntau ua los ntawm txhuas alloy (lub teeb ci ntsa iab) lossis txias {}} rolled steel phaj (siab zog). Cov txheej txheem yuav tsum sib npaug corrosion tsis kam thiab cua sov dissipation.
2. Stator:Cov tub ntxhais ua kom pom tseeb ntawm "rwb thaiv tsev + qhov kub tsis kam" kom ntseeg tau tias hluav taws xob kev nyab xeeb
Cov stator muaj cov tub rog hlau (silicon roj lamination) thiab windings (xov tooj liab), qhov twg thiaj li tsim cov txheej txheem rwb thaiv tsev:
Cov Stator Hlau Core (silicon steel lamints):
Inorganic rwb thaiv tsev txheej, qhov kub ua ntau ntau dua los yog sib npaug rau 200000v, tiv thaiv kev sib tw los tiv thaiv txheej puas tsuaj;
Rau qee qhov siab - Fais Fab Motors: Organic- inorge-} kub, haum rau 150-180℃ua haujlwm.
3. Rotor: Qhia txog "Kev Tiv Thaiv Kab xeb + Tshuav" kom tsis txhob muaj kev tsis txaus siab dynamarance tsis ua hauj lwm
Lub rotor muaj cov rotor tub ntxhais, rotor ncej, thiab cov hlau nplaum tas mus li (rau cov hlau nplaum tas mus li SERVO TSAVs). Cov txheej txheem tsim khoom yuav tsum sib npaug kev tiv thaiv thiab cov sib npaug sib npaug:
Rotor tub ntxhais (silicon steel ntawv):
Zoo ib yam li cov stator tub ntxhais, feem ntau siv inorganic rwb thaiv tsev uas cuam tshuam rau cov coefficity uas cuam tshuam nrog cov baminating coefficient (xav tau ntau dua los yog sib npaug rau 0.95).
4. Lub cev muaj zogFT: YUAV TSUM TAU TXAIS: "Hnav tsis kam + xeb tiv thaiv," feem sib luag nrog bearings thiab thauj khoom
Lub cev muaj zog ncej yog lub zog hloov cov khoom tivthaiv uas tau tiv toj ncaj qha bearings thiab couplings. Kev tsim khoom tsim yuav tsum sib piv kev nyuaj thiab xeb tiv thaiv:
Cov Qauv Txheej Txheem:
Siab - zaus quenching + sib tsoo (Hardness Hrc55-60, rooj plaub) txhim kho cov coj tsis kam; mating saum npoo roughness ra tsawg dua los yog sib npaug rau 0.4μm txo kev coj tus kheej.
Thib peb, txheej txheem kev kho mob deg deg rau cov haujlwm sib txawv: phim raws li cov tseev kom muaj
Lub ntsiab cai tseem ceeb rau kev xaiv Servo Tsav Cov Txheej Txheem Kho Kom Zoo → Kev Tiv Thaiv Cov Txheej Txheem Kev Sib Tw, "Zam Kev Tiv Thaiv Cov Txheej Txheem," Zam Kev Tiv Thaiv Ib Leeg
1. Cov cuab yeej muaj chaw nyob (tshuab cov cuab yeej, cov kab ntau lawm)
Tus phab ntsa:Inorganic rwb thaiv tsev txheej ntawm cov tub ntxhais hlau + h -} chav kawm enameled hlau windings;
Rotor:Inorganic rwb thaiv tsev txheej ntawm cov tub ntxhais hlau + Nickel - tooj liab- nickel plated cov hlau nplaum ruaj khov.
2
Tus phab ntsa:Organic - inorganic composite txheej ntawm cov tub ntxhais hlau + chav kawm chav kawm hauv chav kawm;
Rotor:Electrophoretic txheej ntawm cov hlau nplaum ruaj khov.
3.hu {-}, servo tshuab ze ze cua sov)
Tus phab ntsa:Inorganic rwb thaiv tsev txheej ntawm cov tub ntxhais hlau + chav kawm chav kawm hauv chav kawm rau cov hlau nplaum;
Rotor:High - kub resistant electrophoretic txheej ntawm cov hlau nplaum (qhov kub loj dua los yog sib luag rau 200 degree);
Tsav Ncej:Nitrivonliding kev kho mob (tiv taus siab - oxidation).
Plaub, Kev tshuaj xyuas cov txheej txheem kho cov txheej txheem saum npoo: 3 qhov ntsuas tseem ceeb
Los txiav txim siab yog aSERVO TSAVS cov qauv kev kho deg cov qauv, tsom rau 3 Cov Txheej Txheem Kev Soj Ntsuam kom tsis txhob "txheej txheem ua raws tab sis substard zoo":
Corrosion Kuj:Ntsev tshuaj tsuag (nruab nrab ntawm ntsev tshuaj txau, 5% nacl daws). Tsis muaj xeb rau ntau dua lossis sib npaug rau 48 teev nyob rau hauv ib txwm muaj; Tsis muaj xeb rau ntau dua lossis sib npaug li 200 teev nyob rau hauv cov mob corrosive.
Rwb thaiv tsev kev ua haujlwm:Stator wawb thaiv rwb thaiv tsev Rwb thaiv tsev Rwb thaiv kev ua haujlwm (ntau dua los yog sib npaug ntawm 100mω ntawm qhov ntsuas kub huab cua (1500v / 1 feeb yam tsis muaj kev sib tsoo);
Hnav Kuj:Lub tsev cov ris tsho coj tawm (Mencal hardness ntsuas ntau dua lossis sib npaug), muaj zog} zaus quenched thaj tsam hrc ntau dua lossis sib npaug rau 55).
