Sindingathe kusiyanitsa mitundu yosiyanasiyana ya mabearing Makhalidwe, kusiyana ndi momwe amagwiritsidwira ntchito mitundu 14 ya mabearing

Mabearing amagawidwa m'magulu a ma radial bearing ndi Kunyamulas kutengera komwe katundu akupita kapena ngodya yolumikizirana ndi dzina.

Malinga ndi mitundu ya zinthu zozungulira, zimagawidwa m'magulu monga: mipira yoyendera ndi chozungulira maberiya.

Malinga ndi ngati zingathe kudzilungamitsa zokha, zimagawidwa m'magulu a ma bearing odzilungamitsa okha ndi ma bearing osadzilungamitsa okha (rigid bearings).

Malinga ndi kuchuluka kwa mizere ya zinthu zozungulira, zimagawidwa m'magulu awa: ma bearing a mzere umodzi, ma bearing a mzere umodzi, ndi ma bearing a mzere wambiri.

Malinga ndi ngati zigawozo zitha kulekanitsidwa, zimagawidwa m'magulu monga: ma bearing olekanitsidwa ndi ma bearing osalekanitsidwa.

Kuphatikiza apo, pali kugawa kutengera mawonekedwe ndi kukula kwa kapangidwe kake.

1. Maberamu a Mpira Olumikizana ndi Angular

Pali ngodya yolumikizirana pakati pa mphete ndi mpira. Ma ngodya olumikizirana wamba ndi 15°, 30° ndi 40°. Ngodya yolumikizirana ikakhala yayikulu, mphamvu yolumikizirana imakhala yayikulu; ngodya yolumikizirana ikakhala yaying'ono, imakhala yothandiza kwambiri kuzungulira mwachangu. Ma bearing a mzere umodzi amatha kupirira katundu wa radial ndi katundu wa axial wolunjika. Mwa kapangidwe kake, ma bearing awiri a mzere umodzi a angular contact ball omwe amaphatikizidwa kumbuyo amagawana mphete zamkati ndi zakunja, zomwe zimatha kupirira katundu wa radial ndi katundu wa axial wolunjika.

Ntchito zazikulu

Mzere umodzi: Ma spindle a zida zamakina, ma mota othamanga kwambiri, ma turbine a gasi, olekanitsa a centrifugal, mawilo akutsogolo a magalimoto ang'onoang'ono, ma pinion shafts of differentials.

Mizere iwiri: mapampu amafuta, Zofukiza mizu, ma compressor a mpweya, mitundu yosiyanasiyana ya ma gearbox, mapampu ojambulira mafuta, makina osindikizira.

2. 2Ma Bearings a Mpira Odziyimira Payokha

Mipira yachitsulo yokhala ndi mizere iwiri, yokhala ndi msewu wozungulira wamkati pa mphete yakunja, imatha kusintha yokha kusakhazikika bwino kwa pakati pa shaft chifukwa cha kupotoka kapena kusakhazikika bwino kwa shaft kapena nyumba. Ma bearing opindika amatha kuyikidwa mosavuta pa shaft pogwiritsa ntchito zomangira ndipo makamaka ma bear radial loads.

Ntchito zazikulu: Ma shaft oyendetsera makina opangira matabwa ndi makina opangira nsalu, ma bearing odziyimira okha okhala ndi ma housings.

3. 3Mabearings Odziyendetsa Okha

Mtundu uwu wa bearing uli ndi ma rollers ozungulira pakati pa mphete yakunja yokhala ndi msewu wozungulira ndi mphete yamkati yokhala ndi msewu wozungulira kawiri. Malinga ndi kusiyana kwa kapangidwe ka mkati, umagawidwa m'mitundu inayi: R, RH, RHA ndi SR. Chifukwa chakuti pakati pa arc ya msewu wozungulira wakunja umagwirizana ndi pakati pa bearing, umakhala ndi magwiridwe antchito odzilungamitsa ndipo ukhoza kusintha zokha kusalingana kwa pakati pa shaft komwe kumachitika chifukwa cha kupotoka kapena kusalingana kwa shaft kapena housing. Umatha kupirira katundu wozungulira ndi katundu wa axial wozungulira.

Ntchito zazikulu: Makina opangira mapepala, zipangizo zochepetsera, ma axle a magalimoto a sitima, mipando ya giya ya magiya a magiya ozungulira achitsulo, matebulo ozungulira a magiya ozungulira achitsulo, ma crushers, zotchingira zogwedezeka, makina osindikizira, makina opangira matabwa, ma reducer osiyanasiyana a mafakitale, ma bearing odziyimira okha omwe ali pa vertical mounted self-aligning.

4. 4Mabearings Odziyendetsa Okha

Ma rollers ozungulira amtunduwu amakonzedwa pa ngodya. Chifukwa cha pamwamba pa msewu wozungulira wa mphete ya housing, imakhala ndi magwiridwe antchito odziyimira payokha, zomwe zimapangitsa kuti shaft ikwere pang'onopang'ono. Ili ndi mphamvu yayikulu kwambiri yonyamula katundu wa axial ndipo imatha kupirira katundu wina wa radial pamene ili ndi katundu wa axial. Nthawi zambiri, mafuta odzola amagwiritsidwa ntchito akagwiritsidwa ntchito.

Ntchito zazikulu: Majenereta amagetsi, ma mota amagetsi okhazikika, ma propeller shaft a zombo, zochepetsera zomangira zomangira m'mafakitale ozungulira achitsulo, ma tower cranes, ma crush a malasha, ma extruder, ndi makina opangira.

5. Ma bereji ozungulira opindika

Mtundu uwu wa bearing uli ndi ma conical rollers, omwe amatsogozedwa ndi flange yayikulu ya mphete yamkati. Kapangidwe kake kamapangitsa kuti ma vertice a pamwamba pa conical a pamwamba pa raceway yamkati, pamwamba pa raceway yakunja ya mphete ndi pamwamba pa roller rolling alumikizane pamalo apakati pa bearing. Ma bearing a mzere umodzi amatha kupirira katundu wa radial ndi katundu wa axial wolunjika, pomwe ma bearing a mzere wawiri amatha kupirira katundu wa radial ndi katundu wa axial wolunjika. Ndi oyenera katundu wolemera ndi katundu wogwedezeka.

Ntchito yaikulu: Magalimoto: mawilo akutsogolo, mawilo akumbuyo, ma transmission, ma pinion shafts of differentials. Ma spindles a zida zamakina, makina omangira, makina akuluakulu a zaulimi, zida zochepetsera zida zamagalimoto a sitima, makosi ozungulira ndi zida zochepetsera zida zomangira zitsulo.

6. Maberamu a Mpira Wozama Kwambiri

Mwa kapangidwe kake, mphete iliyonse ya mpira wozungulira mozama imakhala ndi msewu wozungulira mozungulira wokhala ndi gawo lozungulira pafupifupi gawo limodzi mwa magawo atatu a kuzungulira kwa mpirawo. Ma bearing a mpira wozungulira mozama amagwiritsidwa ntchito makamaka kupirira katundu wozungulira ndipo amathanso kunyamula katundu wina wa axial.

Pamene kuwala kwa radial kwa bearing kukuwonjezeka, kumakhala ndi mawonekedwe a angular contact ball bearings ndipo kumatha kupirira katundu wosinthasintha wa axial mbali zonse ziwiri. Poyerekeza ndi mitundu ina ya bearing ya kukula komweko, mtundu uwu wa bearing uli ndi coefficient yocheperako ya friction, liwiro locheperako komanso kulondola kwambiri, zomwe zimapangitsa kuti ikhale mtundu wa bearing womwe ogwiritsa ntchito amakonda posankha.

Ntchito zazikulu: magalimoto, mathirakitala, zida zamakina, ma mota, mapampu amadzi, makina a zaulimi, makina osoka, ndi zina zotero.

7. Maberamu a Mpira Wotambasulidwa

Imapangidwa ndi mphete ya msewu wothamanga ngati gasket yokhala ndi msewu wothamanga, mpira ndi khola. Mphete ya msewu wothamanga yomwe imagwirizana ndi shaft imatchedwa mphete ya shaft, ndipo mphete ya msewu wothamanga yomwe imagwirizana ndi nyumbayo imatchedwa mphete ya mpando. Ma bearing olunjika kawiri amakwanira mphete yapakati ndi shaft. Ma bearing olunjika kamodzi amatha kupirira katundu wa axial wolunjika mbali imodzi, pomwe ma bearing olunjika kawiri amatha kupirira katundu wa axial wolunjika mbali ziwiri (palibe amene angapirire katundu wa radial).

Ntchito zazikulu: mapini owongolera magalimoto, ma spindles a zida zamakina.
