2.1 Bearing uye basa rayo muchimiro chemota
Zvimiro zvezvishandiso zvemagetsi zvakajairika zvinosanganisira motor rotor (shaft, rotor core, winding), stator (stator core, stator winding, junction box, end cover, bearing cover, etc.) uye connecting parts (bearing, seal, carbon brush, etc.) nezvimwe zvinhu zvikuru. Muzvikamu zvese zve motor structure, mamwe bear shaft ne radial load asi haana internal relative movement yawo; Mamwe e internal relative movement mushure me asi haatakure axis, radial load. Mabearings chete ndiwo anotakura shaft ne radial loads achifambisa zviri mukati (zvichienderana ne inner ring, outer ring ne rolling body). Saka, bearing pachayo chikamu chinonzwisisika che motor structure. Izvi zvinosarudzawo kukosha kwe bearing layout muma industrial motors.
Dhayagiramu yekuongorora chibooreso chemagetsi
2.2 Matanho ekutanga ekurongeka kwebheyaringi mumota
Kurongeka kwema "rolling bearings" muma "electrical tool motors" kunoreva maitiro ekuisa mhando dzakasiyana dzema "bearings" mu "system" mu "shafting" kana mainjiniya vachigadzira chimiro che "electrical tool motors". Kuti uwane kurongeka kwakakodzera kwe "motor bearing", zvinodiwa kuti:
Danho rekutanga: nzwisisa mamiriro ekushanda kwemabheyaringi anotenderera muzvishandiso. Izvi zvinosanganisira:
- Mota yakatwasuka kana mota yakatwasuka
Kushanda kwemagetsi uchishandisa chibooreso chemagetsi, saha remagetsi, pick yemagetsi, nyundo yemagetsi nedzimwe mhando dzakasiyana, zvinosimbisa mota muchimiro chekuisa vertical nehorizontal bearing, kutungamira kwayo mutoro kuchasiyana. Kune mota dzakatwasuka, giravhiti ichave radial load, uye kune mota dzakatwasuka, giravhiti ichave axial load. Izvi zvinokanganisa zvakanyanya sarudzo yerudzi rwebearing uye marongerwo ebearing mumota.
- Kumhanya kunodiwa kwemota
Kumhanya kunodiwa nemota kuchakanganisa saizi yebheyaringi uye kusarudzwa kwerudzi rwebheyaringi, pamwe chete nemagadzirirwo ebheyaringi iri mumota.
- Kuverenga kwekutakura mutoro une simba
Zvichienderana nekumhanya kwemota, simba/torque yakayerwa uye mamwe ma parameter, referensi (GB/T6391-2010/ISO 281 2007) yekuverenga mutoro unoshanduka wemabhora, sarudza saizi yakakodzera yemabhora emabhora, giredhi rekunyatsojeka nezvimwewo.
- Zvimwe zvinodiwa: zvakaita sezvinodiwa zve axial channeling, kudedera, ruzha, kudzivirira guruva, mutsauko wezvinhu zvefuremu, kutsvedza kwemota, nezvimwewo.
Muchidimbu, usati watanga kugadzira nekusarudza mabheyaringi emota dzemagetsi, zvakakosha kuti uve nekunzwisisa kwakazara kwemamiriro chaiwo ekushanda kwemota, kuitira kuti uve nechokwadi chekuti yakasarudzwa zvine musoro uye zvakavimbika.
Danho rechitatu: Sarudza rudzi rwebheyaringi.
Zvichienderana nematanho maviri ekutanga, chimiro chemutoro wemabheari uye shaft system yemagumo akasarudzwa akagadzika uye magumo anoyangarara zvinotariswa, uye mhando dzakakodzera dzemabheari dzinosarudzwa dzemagumo akagadzika uye magumo anoyangarara zvichienderana nehunhu hwemabheari.
3. Mienzaniso yemaitiro emhando yekutakura mota
Kune mhando dzakawanda dzemagadzirirwo emabheyaringi emota. Chimiro chebheyaringi chemota chinowanzoshandiswa chine mhando dzakasiyana dzekuisa uye magadzirirwo. Izvi zvinotevera zvinotora chimiro chebheyaringi rebhora rakadzika kaviri semuenzaniso:
3.1 Chimiro chebhora rekutakura rakadzika kaviri
Chimiro che "double deep groove ball bearing" ndicho chimiro chinowanzo shandiswa mumota dzemaindasitiri, uye chimiro chayo chikuru chekutsigira "shafting" chine ma "deep groove ball bearing" maviri. Ma "deep groove ball bearing" maviri anowirirana.
Sezvakaratidzwa mumufananidzo uri pazasi:
Profile yebheyaringi
Mumufananidzo, shaft extension end bearing ndiyo positioning end bearing, uye non-shaft extension end bearing ndiyo floating end bearing. Migumo miviri yebearing inotakura radial load iri pashafting, nepo positioning end bearing (iri pa shaft extension end muchimiro ichi) inotakura axial load yeshafting.
Kazhinji kurongeka kwebheyaringi remota yechimiro ichi kwakakodzera kuti mutoro weaxial radial wemota usiri mukuru. Kazhinji kusanganiswa kwemutoro wechimiro chemota diki kunoitika.
