2.1 Cov kabmob thiab nws txoj haujlwm hauv lub cev muaj zog
Cov cuab yeej siv hluav taws xob muaj xws li lub cev muaj zog rotor (ncej, rotor core, winding), stator (stator core, stator winding, junction box, kawg cover, bearing cover, thiab lwm yam) thiab txuas cov khoom (cov kabmob, foob, carbon txhuam, thiab lwm yam) thiab lwm yam tseem ceeb. Nyob rau hauv tag nrho cov qhov chaw ntawm lub cev muaj zog qauv, ib co dais ncej thiab radial load tab sis tsis muaj lawv tus kheej nyob rau hauv tus txheeb ze zog; Qee qhov ntawm lawv tus kheej sab hauv cov txheeb ze txav tom qab tab sis tsis dais axis, radial load. Tsuas yog cov bearings dais ob lub ncej thiab radial loads thaum tsiv txheeb ze rau ib leeg sab hauv (kwv yees rau lub nplhaib puab, lub nplhaib sab nraud thiab lub cev dov). Yog li ntawd, tus kabmob nws tus kheej yog ib feem ntawm lub cev muaj zog. Qhov no kuj txiav txim siab qhov tseem ceeb ntawm cov kabmob layout nyob rau hauv industrial motors.

2.2 Cov kauj ruam yooj yim ntawm dov bearing layout nyob rau hauv lub cev muaj zog
Lub layout ntawm dov bearings nyob rau hauv hluav taws xob twj motors hais txog cov txheej txheem ntawm yuav ua li cas tso ntau hom bearings rau hauv lub system nyob rau hauv lub shafting thaum engineers tsim cov qauv ntawm hluav taws xob cuab tam motors. Txhawm rau kom ua tiav qhov kev tswj hwm lub cev muaj zog, nws yog qhov yuav tsum tau ua:
Thawj kauj ruam: nkag siab txog kev ua haujlwm ntawm dov bearings hauv cov cuab yeej. Cov no suav nrog:
- Kab rov tav lub cev muaj zog lossis ntsug lub cev muaj zog
Hluav taws xob ua haujlwm nrog lub tshuab hluav taws xob, hluav taws xob pom, hluav taws xob xaiv, hluav taws xob rauj thiab lwm yam sib txawv, paub meej tias lub cev muaj zog nyob rau hauv daim ntawv ntawm kev teeb tsa ntawm ntsug thiab kab rov tav, nws cov kev taw qhia load yuav txawv. Rau cov motors kab rov tav, lub ntiajteb txawj nqus yuav yog radial load, thiab rau ntsug motors, lub ntiajteb txawj nqus yuav yog axial load. Qhov no yuav ua rau muaj kev cuam tshuam zoo rau kev xaiv ntawm cov kabmob thiab cov kabmob layout hauv lub cev muaj zog.
- Qhov xav tau ceev ntawm lub cev muaj zog
Qhov yuav tsum tau ceev ntawm lub cev muaj zog yuav cuam tshuam qhov loj ntawm cov kabmob thiab kev xaiv ntawm cov kabmob, nrog rau kev teeb tsa ntawm cov kabmob hauv lub cev muaj zog.
- Kev suav cov kabmob dynamic load
Raws li lub cev muaj zog ceev, ntsuas lub zog / torque thiab lwm yam tsis muaj, siv (GB / T6391-2010 / ISO 281 2007) los xam cov dynamic load ntawm pob bearings, xaiv qhov tsim nyog loj ntawm pob bearings, precision qib thiab lwm yam.
- Lwm yam yuav tsum tau muaj: xws li axial channeling yuav tsum, kev co, suab nrov, kev tiv thaiv plua plav, qhov sib txawv ntawm cov khoom ntawm tus ncej, qaij lub cev muaj zog, thiab lwm yam.
Nyob rau hauv luv luv, ua ntej pib tsim thiab xaiv cov cuab yeej hluav taws xob lub cev muaj zog bearings, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab zoo ntawm cov kev ua haujlwm tiag tiag ntawm lub cev muaj zog, txhawm rau ua kom ntseeg tau tias tsim nyog thiab txhim khu kev qha xaiv tom kawg.
Kauj Ruam 3: Txiav txim siab hom kabmob.
Raws li thawj ob kauj ruam, bearing load thiab ncej system qauv ntawm cov xaiv ruaj kawg thiab ntab kawg yog txiav txim siab, thiab ces tsim nyog bearing hom raug xaiv rau qhov kawg thiab ntab kawg raws li cov kabmob bearing yam ntxwv.
3. Piv txwv ntawm lub cev muaj zog bearing layout
Muaj ntau ntau hom motor bearing layout. Feem ntau siv lub cev muaj zog bearing qauv muaj ntau yam installation thiab qauv. Cov hauv qab no siv qhov pom tseeb tshaj plaws ob chav sib sib zog nqus groove pob bearing qauv ua piv txwv:
3.1 Ob chav sib sib zog nqus groove pob bearing qauv
Ob chav sib sib zog nqus groove pob bearing qauv yog cov qauv shafting ntau tshaj plaws nyob rau hauv industrial motors, thiab nws lub ntsiab shafting kev txhawb nqa qauv yog tsim los ntawm ob qhov sib sib zog nqus groove pob bearings. Ob tug sib sib zog nqus groove pob bearings dais ua ke.
Raws li pom hauv daim duab hauv qab no:
Bearing profile
Nyob rau hauv daim duab, tus ncej extension kawg bearing yog positioning kawg bearing, thiab cov tsis-shaft extension kawg bearing yog lub floating kawg bearing. Ob qhov kawg ntawm cov kabmob dais lub radial load ntawm lub shafting, thaum lub positioning kawg bearing (nyob ntawm tus ncej extension kawg nyob rau hauv cov qauv no) dais lub axial load ntawm lub shafting.
Feem ntau lub cev muaj zog bearing kev npaj ntawm cov qauv no yog tsim rau lub cev muaj zog axial radial load tsis loj. Feem ntau yog qhov sib txuas ntawm qhov load ntawm micro motor qauv.
