Makhalidwe ndi kagwiritsidwe ntchito ka mitundu 14 ya ma bearing akuwunikidwa mokwanira

Bearing ndi gawo lofunika kwambiri pazida zamakanika, ntchito yayikulu ndikuthandiza thupi lozungulira, kuchepetsa kupsinjika kwa njira yotumizira. Malinga ndi njira zosiyanasiyana zogawa, ma bearing amatha kugawidwa m'mitundu yambiri. Izi ndi makhalidwe, kusiyana ndi kagwiritsidwe ntchito ka ma bearing 14 wamba:

1. Kulumikizana kozungulira Kunyamula mpira
Mawonekedwe: Pali ngodya yolumikizirana pakati pa mphete ndi mpira, ngodya yolumikizirana yokhazikika ndi 15°, 30° ndi 40°, ngodya yolumikizirana ikakhala yayikulu, mphamvu yolumikizirana ikakhala yayikulu, ngodya yolumikizirana ikakhala yaying'ono, zimakhala zosavuta kuzungulira mwachangu. Chogwirira cha mzere umodzi chimatha kupirira katundu wa radial ndi katundu wa axial womwe uli mbali imodzi.

Ntchito: Chigawo chimodzi cha spindle ya zida zamakina, mota yama frequency apamwamba, turbine ya gasi, ndi zina zotero. Mzere wawiri wa pampu yamafuta, Roots blower, ndi zina zotero.

2. Kulinganiza mpira wozungulira
Mawonekedwe: Mizere iwiri ya mipira yachitsulo, msewu wakunja wa mphete ndi mtundu wamkati wozungulira, womwe ungasinthe zokha cholakwika cha axis chomwe chimachitika chifukwa cha kupotoka kwa shaft kapena mtima wosiyana wa chipolopolo. Ma bearing opindika amatha kuyikidwa mosavuta pa shaft pogwiritsa ntchito zomangira ndipo makamaka katundu wa radial.

Ntchito: makina opangira matabwa, shaft yoyendetsera makina opangira nsalu, bedi lolinganiza loyima ndi mpando, ndi zina zotero.

3. Kudzigwirizanitsa chogwirira chozungulira
Mawonekedwe: Pali ma rollers ozungulira pakati pa mphete yakunja ya msewu wozungulira ndi mphete yamkati ya msewu wozungulira wawiri, omwe amagawidwa m'mitundu inayi ya R, RH, RHA ndi SR malinga ndi kapangidwe ka mkati. Chifukwa chakuti pakati pa msewu wozungulira wa msewu wozungulira wa mphete yakunja pamakhala kogwirizana ndi pakati pa bearing, ili ndi magwiridwe antchito olinganiza, ndipo imatha kusintha yokha cholakwika cha axis chomwe chimayambitsidwa ndi kupotoka kwa shaft kapena nyumba kapena malo osiyanasiyana, ndipo imatha kupirira katundu wa radial ndi katundu wa axial wa njira ziwiri.

Ntchito: makina opangira mapepala, chochepetsera liwiro, axle ya galimoto ya sitima, ndi zina zotero.

4. Kanikizani chodzipangira chodzipangira chodzipangira
Mawonekedwe: Kapangidwe kake kozungulira kozungulira, pamwamba pa msewu wa mpikisano wa mipando ndi kozungulira, ndi magwiridwe antchito olinganiza, zomwe zimathandiza kuti shaft ikhale ndi makwerero angapo, mphamvu ya axial load ndi yayikulu kwambiri, mu axial load imathanso kupirira ma radial load angapo.

Ntchito: jenereta ya hydraulic, mota yoyimirira, ndi zina zotero.

5. Chogwirira chozungulira chopindika
Mawonekedwe: Chokhala ndi chozungulira tebulo, chozunguliracho chimatsogozedwa ndi m'mphepete waukulu wa chitetezo chamkati, kapangidwe kake kamapangitsa kuti pamwamba pa msewu wamkati wa mphete, pamwamba pa msewu wakunja wa mphete ndi makona a pamwamba pa roller rolling zilumikizane pamalo omwe ali pakati pa mzere woperekera. Chozungulira cha mzere umodzi chimatha kunyamula katundu wa radial ndi katundu wa axial wolunjika, chozungulira cha mizere iwiri chimatha kunyamula katundu wa radial ndi katundu wa axial wolunjika mbali zonse ziwiri.

Ntchito: gudumu lakutsogolo lagalimoto, gudumu lakumbuyo, giya, ndi zina zotero.

6. Kutengera mpira wozama kwambiri
Mawonekedwe: Mphete iliyonse ya bearing ya mpira wa groove yozama pa kapangidwe kake ili ndi msewu wopitilira wa groove wokhala ndi gawo lozungulira pafupifupi gawo limodzi mwa magawo atatu a equatorial circumference ya mpirawo. Amagwiritsidwa ntchito kwambiri kunyamula katundu wa radial, amathanso kunyamula katundu winawake wa axial. Pamene kuwala kwa radial kwa bearing kukuwonjezeka, kumakhala ndi mphamvu ya bearing ya mpira wolumikizana ndi angular ndipo kumatha kupirira katundu wa axial mosinthana mbali ziwiri.

Ntchito: galimoto, thirakitala, chida cha makina, ndi zina zotero.

7. Kunyamula mpira wothamanga
Mawonekedwe: Imapangidwa ndi mphete ya gasket raceway yokhala ndi raceway ndi gulu la mpira ndi khola. Mphete ya raceway yogwirizana ndi shaft imatchedwa shaft ring, ndipo mphete ya raceway yogwirizana ndi chipolopolo imatchedwa seat ring. Ma bearing a njira ziwiri amafanana ndi shaft yachinsinsi ya mphete yapakati, ma bearing a njira imodzi amatha kupirira katundu wa axial wa njira imodzi, ndipo ma bearing a njira ziwiri amatha kupirira katundu wa axial wa njira ziwiri (zonse sizingathe kupirira katundu wa radial).

Ntchito: pini yoyendetsera galimoto, chosinthira zida zamakina, ndi zina zotero.

8. Chogwirira chozungulira cholumikizira
Mawonekedwe: Amagwiritsidwa ntchito kunyamula katundu wa axial wa shaft yayikulu, katundu wophatikizidwa, koma katundu wotalikirapo sayenera kupitirira 55% ya katundu wa axial. Poyerekeza ndi ma bearing ena odulira, mtundu uwu wa bearing uli ndi friction factor yotsika, liwiro lapamwamba komanso kuthekera kolumikizana. Roller ya mtundu wa 29000 bearing ndi asymmetrical spherical roller, yomwe ingachepetse kutsetsereka kwa ndodo ndi raceway pantchito.

Ntchito: jenereta ya hydraulic, mbedza ya crane, ndi zina zotero.

9. Chogwirira cha cylindrical roller
Mawonekedwe: Chozungulira cha chozungulira chozungulira nthawi zambiri chimatsogozedwa ndi m'mbali ziwiri za mphete yonyamulira, ndipo chozungulira cha khola ndi mphete yotsogolera zimapanga kuphatikiza, komwe kumatha kulekanitsidwa ndi mphete ina yonyamulira ndipo kumakhala kwa chogwirira cholekanitsidwa. Kukhazikitsa ndi kusokoneza kumakhala kosavuta, makamaka pamene mphete zamkati ndi zakunja zikufunika kuti zigwirizane ndi shaft ndi nyumba. Maberiya otere nthawi zambiri amagwiritsidwa ntchito kunyamula katundu wozungulira, ndipo maberiya a mzere umodzi okha okhala ndi mphete zamkati ndi zakunja ndi ma alonda amatha kunyamula katundu waung'ono wokhazikika wa axial kapena katundu wamkulu wa axial wosinthasintha.

Ntchito: mota yayikulu, chosinthira zida zamakina, ndi zina zotero.
