Mndandanda wa ma bere ozungulira

Ma roller bearing ndi mtundu wofala wa ma bearing womwe umagwiritsa ntchito ma roller ngati zinthu zozungulira m'malo mwa mipira. Posankha ma roller bearing, ndikofunikira kuganizira zinthu monga Inner Diameter, Outer Diameter, Load Direction, Mtundu wa roller bearing (monga Needle Roller, Self-Aligning, Cylindrical Roller, ndi zina zotero), zinthu, ndi zina zotero.

 

Mabeya ozungulira a cylindrical

Ma rollers a cylindrical ali pamzere wolumikizana ndi msewu wa raceway, ndipo mphamvu ya radial load ndi yayikulu, yomwe ndi yoyenera kunyamula katundu wolemera komanso katundu wokhudza kugwedezeka, komanso yoyenera kutembenuza mwachangu mtundu wa N ndipo mtundu wa NU ukhoza kusuntha mozungulira, ukhoza kusintha malinga ndi kusintha kwa malo ogwirizana a shaft ndi chipolopolo chifukwa cha kukulitsa kutentha kapena cholakwika chokhazikitsa, ndipo ndi oyenera kwambiri kugwiritsidwa ntchito ngati ma bearing aulere, mtundu wa NJ ndi mtundu wa NF zimatha kunyamula katundu wina wa axial, mtundu wa NH ndi mtundu wa NUP zimatha kunyamula katundu wina wa axial, mphete yamkati kapena mphete yakunja imatha kulekanitsidwa, ndipo ndikosavuta kusonkhanitsa ndikuchotsa mtundu wa NNU ndi mtundu wa NN zimakhala ndi kulimba kwamphamvu motsutsana ndi katundu wa radial, zomwe zimagwiritsidwa ntchito kwambiri pa ma spindles a zida zamakina.

 

Makhola akuluakulu ogwiritsidwa ntchito: khola loponda mbale yachitsulo (yooneka ngati Z), khola lodulidwa ndi aloyi yamkuwa, khola la pini, khola lopangira utomoni wopangidwa

Ntchito zazikulu: ma mota apakatikati ndi akuluakulu, ma jenereta, mainjini oyatsa mkati, ma turbine a gasi, ma spindles a zida zamakina, zida zochepetsera, makina okweza ndi kutsitsa, ndi makina osiyanasiyana amafakitale.

 

Mabeya ozungulira singano olimba

Kapangidwe koyambira ka bearing yokhala ndi mphete yamkati ndi kofanana ndi ka bearing ya cylindrical ya NU, koma chifukwa chogwiritsa ntchito ma needle rollers, voliyumu imatha kuchepetsedwa, ndipo imatha kupirira katundu waukulu wa radial.

Khola lalikulu loyenera: khola lopondaponda mbale yachitsulo

 

Ntchito zazikulu: mainjini a magalimoto, ma transmission, mapampu, mawilo oyendera, ma hoist, ma cranes opita pamwamba, ma compressor

 

Ma bereji ozungulira opindika

Maberiya awa ali ndi ma rollers ozungulira a tebulo, omwe amatsogozedwa ndi flange yayikulu mkati mwa mphete yamkati.

Kapangidwe kake ndi kamene kamapangitsa kuti malo otsetsereka a pamwamba pa msewu wamkati wa mphete, pamwamba pa msewu wakunja wa mphete, ndi pamwamba poterera pa malo ozungulira ozungulira amakumana pamalo ozungulira pakati pa mzere wozungulira.

Ma bearing a mzere umodzi amatha kupirira katundu wa axial wa radial ndi unidirectional, ndipo ma bearing a mzere wawiri amatha kupirira katundu wa axial wa radial ndi bidirectional.

Yoyenera katundu wolemera komanso katundu woopsa

Malinga ndi chifuwa cholumikizirana (α) chosiyana, chimagawidwa m'mitundu itatu: ngodya yaying'ono ya koni, ngodya yapakati ya koni ndi ngodya yayikulu ya koni, ndipo ngodya yolumikizirana ikakhala yayikulu, mphamvu ya axial load imakula.

Mphete yakunja imalekanitsidwa ndi gulu lamkati (gulu la mphete yamkati ndi gulu la zozungulira ndi khola) kuti ikhale yosavuta kusonkhanitsa ndi kusokoneza

Mabearing okhala ndi code yothandizira yakumbuyo "J" kapena "JR" amatha kusinthidwa padziko lonse lapansi

Mtundu uwu wa bearing umagwiritsanso ntchito zinthu zamtundu wa inchi

 

Makhola akuluakulu ogwiritsidwa ntchito: makhola oponda mbale zachitsulo, makhola opangira utomoni, makhola a pini

Ntchito yaikulu: magalimoto: mawilo akutsogolo, mawilo akumbuyo, ma transmission, ma differentials, ma pinion shafts. Ma spindles a zida zamakina, makina omangira, makina akuluakulu a zaulimi, chipangizo chochepetsera zida zamagalimoto a sitima, khosi lozungulira mphero ndi chipangizo chochepetsera mphamvu

 

Ma bereji ozungulira ozungulira

Mtundu uwu wa kuberekera uli ndi zozungulira zozungulira pakati pa mphete yakunja ya msewu wozungulira ndi mphete yamkati ya msewu wozungulira wawiri, ndipo umagawidwa m'mitundu inayi: R, RH, RH ndi SR malinga ndi kapangidwe ka mkati kosiyana.

 

Popeza pakati pa arc ya msewu wakunja wa mphete ndi chimodzimodzi ndi pakati pa bearing, imakhala ndi magwiridwe antchito odziyimira payokha, kotero kusokonekera kwa shaft komwe kumachitika chifukwa cha kupotoka kapena kusakhazikika kwa shaft kapena housing kumatha kusinthidwa zokha.

 

Imatha kupirira katundu wa axial wa radial ndi bidirectional axial. Makamaka, mphamvu ya katundu wa radial ndi yayikulu, ndipo ndi yoyenera kunyamula katundu wolemera komanso katundu woopsa.

 

Ma bearing opindika amatha kuyikidwa ndikuchotsedwa pa shaft pogwiritsa ntchito zomangira kapena zomangira zochotsera

Pali mitundu iwiri ya mabowo opindika (taper):

1:30 (Khodi Yothandizira: K30) ...... Yoyenera mndandanda wa 240 ndi 241

1:12 (Khodi Yothandizira: K) ......... Yoyenera mndandanda wina

Mphete yakunja ikhoza kukhazikitsidwa ndi dzenje la mafuta, dzenje la mafuta ndi dzenje loikapo pini (limodzi). Mabowo a mafuta ndi dzenje la mafuta zitha kukhazikitsidwanso pa mphete yamkati.

 

Makhola akuluakulu ogwiritsidwa ntchito: makola odulidwa ndi alloy amkuwa, makola opondaponda mbale zachitsulo, makola a pini, makola opangira utomoni

Ntchito zazikulu: makina opangira mapepala, chipangizo chochepetsera, axle ya galimoto ya sitima, mpando wa gearbox ya mphero yozungulira, tebulo lozungulira mphero yozungulira, chotsukira, chophimba chogwedezeka, makina osindikizira, makina opangira matabwa, zochepetsera zosiyanasiyana zamafakitale, mabearing odziyimira okha okhala ndi mipando
