Ma bearings ndi zinthu zofunika kwambiri pazida zamakina. Ntchito yake yayikulu ndikuthandizira makina ozungulira thupi kuti achepetse kugundana kwamphamvu yamakina panthawi yotumizira zida.
Ma bearings amagawidwa kukhala ma radial bearings ndi ma thrust bears motengera mayendedwe osiyanasiyana onyamula katundu kapena ngodya zolumikizirana mwadzina.
Malinga ndi mtundu wa zinthu zogubuduza, zimagawidwa kukhala: mayendedwe a mpira ndi mayendedwe odzigudubuza.
Malingana ndi momwe angagwirizanitsire, amagawidwa kukhala: mayendedwe odzipangira okha ndi osagwirizana (olimba).
Malingana ndi chiwerengero cha mizere ya zinthu zogubuduza, iwo amagawidwa kukhala: mayendedwe a mzere umodzi, mizere iwiri, ndi mizere yambiri.
Malingana ndi ngati zigawozo zikhoza kulekanitsidwa, zimagawidwa kukhala: mayendedwe olekanitsidwa ndi osagwirizana.
Palinso magulu otengera mawonekedwe ndi kukula kwake.
Nkhaniyi imagawana makamaka mawonekedwe, kusiyana ndi kugwiritsiridwa ntchito kofanana kwa 14 mayendedwe wamba.
1 Angular kukhudzana mpira mayendedwe
Pali njira yolumikizirana pakati pa ferrule ndi mpira. Ma angles okhudzana ndi 15 °, 30 ° ndi 40 °. Kukula kolumikizana ndi ngodya, kumapangitsanso kuchuluka kwa axial katundu. Pang'onoting'ono pakona yolumikizana, imathandizira kwambiri kuzungulira kothamanga kwambiri. Mizere ya mzere umodzi imatha Kunyamula katundu wa radial ndi unidirectional axial load. Mwadongosolo, mizere iwiri yolumikizana ndi mizere yolumikizana kumbuyo imagawana mphete yamkati ndi mphete yakunja ndipo imatha kunyamula katundu wa radial ndi bidirectional axial load.
Cholinga chachikulu:
Mzere umodzi: spindle chida cha makina, mota yothamanga kwambiri, turbine yamagetsi, cholekanitsa chapakati, gudumu lakutsogolo lagalimoto yaying'ono, shaft yosiyana.
Mzere wapawiri: mapampu amafuta, zowombera Mizu, ma compressor a mpweya, ma transmission osiyanasiyana, mapampu a jakisoni wamafuta, makina osindikizira.
2 Kulumikizana kwa mpira
Mizere iwiri ya mipira yachitsulo, msewu wakunja wa mphete ndi mtundu wamkati wozungulira, kotero umatha kusintha kusintha kwapakati pa shaft chifukwa cha kupatuka kapena kusakhazikika kwa shaft kapena nyumba. Chovala cha tapered bore chikhoza kukhazikitsidwa mosavuta pa shaft pogwiritsa ntchito zomangira. Makamaka Bear radial load.
Ntchito zazikuluzikulu: makina opangira matabwa, makina opangira nsalu amayendetsa ma shafts, oyima okhala odziyendetsa okha.
3 Zozungulira zozungulira
Mtundu woterewu umakhala ndi zodzigudubuza zozungulira pakati pa mphete yakunja yozungulira yozungulira komanso mphete yamkati yamkati. Malinga ndi mapangidwe amkati osiyanasiyana, amagawidwa m'mitundu inayi: R, RH, RHA ndi SR. Popeza arc pakati pa msewu wakunja wa mphete ndi The bearing center ndi yokhazikika ndipo imakhala yodzigwirizanitsa yokha, kotero imatha kusintha kusintha kwa shaft center chifukwa cha kupotoza kapena kusasunthika kwa shaft kapena nyumba, ndipo imatha kupirira katundu wa radial ndi bidirectional axial katundu.
Ntchito zazikuluzikulu: makina opangira mapepala, magiya ochepetsera, ma axle agalimoto yanjanji, mipando yama giya giya, zogudubuza mphero, ma crushers, zowonera, makina osindikizira, makina opangira matabwa, zochepetsera m'mafakitale osiyanasiyana, zozungulira zozungulira.
4 Kondani chozungulira chozungulira
Zodzigudubuza zozungulira mumtundu woterewu zimakonzedwa mozungulira. Popeza msewu wothamanga wa mphete ya mpando ndi wozungulira ndipo uli ndi katundu wodzigwirizanitsa, umatha kulola kuti shaft igwedezeke pang'ono. Mphamvu ya axial katundu ndi yaikulu kwambiri. Imatha kunyamula katundu angapo axial nthawi imodzi. Radial load, mafuta opaka mafuta nthawi zambiri amagwiritsidwa ntchito.
Ntchito zazikuluzikulu: ma hydraulic jenereta, ma mota oyimirira, ma propeller shafts a zombo, zochepetsera zomangira mphero, ma crane a nsanja, mphero zamakala, ma extruder, ndi makina opangira.
5 Tapered Roller Bearings
Mtundu woterewu uli ndi ma roller amtundu wa truncated. Odzigudubuza amatsogoleredwa ndi nthiti zazikulu za mphete yamkati. Amapangidwa kuti nsonga za mawonekedwe owoneka bwino amkati mwa mphete yamtundu wamtundu wamtundu wakunja, njira yakunja ya mphete ndi yodzigudubuza imadutsa pakati pa mzere wapakati. Pa mfundo. Mizere ya mzere umodzi imatha kunyamula katundu wa radial ndi njira imodzi ya axial katundu, pamene mizere iwiri ya mizere imatha kunyamula katundu wa radial ndi njira ziwiri za axial katundu, ndipo ndi yoyenera kunyamula katundu wolemera ndi katundu wokhudzidwa.
Ntchito zazikulu: Magalimoto: mawilo akutsogolo, mawilo akumbuyo, ma transmissions, ma pinion shafts. Makina opangira zida zamakina, makina omanga, makina akuluakulu aulimi, zida zochepetsera zida zamagalimoto a njanji, makosi opukutira mphero ndi zida zochepetsera.
6 Mpira wakuya wakuya
Mwamadongosolo, mphete iliyonse ya mpira wakuya wa groove ili ndi msewu wopitilira muyeso wokhala ndi gawo limodzi mwamagawo atatu a circumference ya mpirawo. Mipira yozama kwambiri imagwiritsidwa ntchito makamaka kunyamula katundu wa radial ndipo imathanso kunyamula katundu wina wa axial.
Chilolezo cha radial chikachulukirachulukira, chimakhala ndi mawonekedwe amtundu wolumikizana ndi mpira ndipo chimatha kupirira katundu wosiyanasiyana wa axial mbali ziwiri. Poyerekeza ndi mitundu ina ya mayendedwe a kukula kwake, mtundu uwu wa kunyamula umakhala ndi kagawo kakang'ono kameneka, kuthamanga kwa malire, ndi kulondola kwambiri. Ndilo mtundu wonyamulira wokonda kwa ogwiritsa ntchito posankha.
Ntchito zazikulu: magalimoto, mathirakitala, zida zamakina, ma mota, mapampu amadzi, makina aulimi, makina opangira nsalu, etc.
7 Kuthamanga kwa mpira
Zimapangidwa ndi mphete yojambulira ngati washer yokhala ndi msewu wothamanga komanso msonkhano wa mpira ndi khola. Mphete yothamanga yomwe imafanana ndi shaft imatchedwa mphete ya shaft, ndipo mphete yothamanga yomwe imagwirizana ndi chipolopolo imatchedwa mphete yapampando. Kubereka kwanjira ziwiri kumafanana ndi tsinde lachinsinsi la mphete yapakati. Njira imodzi yokha imatha kunyamula katundu wa axial wa njira imodzi, ndipo njira ziwiri zimatha kunyamula katundu wa axial wanjira ziwiri (ngakhalenso sungathe kunyamula katundu wa radial).
Ntchito zazikulu: zikhomo zowongolera magalimoto, masipilo a zida zamakina.
Zida za Xinfa CNC zili ndi mawonekedwe abwino komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:
