Bearings zvinhu zvakakosha mumichina michina. Basa rayo guru ndere kutsigira mechanical inotenderera muviri kuderedza friction coefficient ye mechanical load panguva yekufambisa nzira yemidziyo.
Mabearings akakamurwa kuita radial mabearings uye thrust bearings zvichienderana neakasiyana kutakura mitoro nzira kana nominal contact angles.
Zvinoenderana nerudzi rwekukunguruka zvinhu, zvakakamurwa kuita: bhora mabheji uye roller mabheji.
Zvinoenderana nekuti vanogona kurongeka, ivo vakakamurwa kuva: kuzvidzora mabheji uye asina-kurongedza mabheji (rigid bearings).
Zvichienderana nehuwandu hwemitsara yezvinhu zvinotenderedza, zvakakamurwa kuita: mutsara mumwe chete, maviri-mutsara mabhengi, uye akawanda-mutsara mabhengi.
Maererano kana zvikamu zvinogona kuparadzaniswa, zvakakamurwa kuva: mabheji akaparadzaniswa uye asina kuparadzaniswa.
Kune zvakare kupatsanurwa kunoenderana nechimiro chechimiro uye saizi.
Ichi chinyorwa chinonyanya kugovera maitiro, misiyano uye mashandisirwo anoenderana e14 akajairwa mabhengi.
8 Kanda bhora
Thrust roller bearings inoshandiswa kune shafts inotakura kunyanya axial mutoro uye yakasanganiswa meridional load, asi meridional load haifaniri kudarika 55% yeaxial load. Kuenzaniswa nemamwe ma thrust roller bearings, rudzi urwu rwekutakura rune yakaderera friction coefficient, yakakwirira kutenderera kumhanya, uye inokwanisa kugadzirisa. Iwo ma rollers e29000 anotakura asymmetric spherical rollers, ayo anogona kuderedza kutsvedza kwehama pakati petsvimbo uye mujaho panguva yekushanda. Ma rollers akareba uye ane dhayamita yakakura. Vane nhamba huru ye rollers uye mutoro mukuru wekutakura. Kazhinji ivo vanozorwa nemafuta. Mafuta ekuzora anogona kushandiswa nekumhanya kwakaderera.
Kushandiswa kukuru: hydraulic generator, crane hooks.
9 Cylindrical Roller Bearings
Iyo rollers ye cylindrical roller bearings inowanzotungamirirwa nembabvu mbiri dzemhete inotakura. Iyo cage roller uye mhete yekutungamira inoumba musangano unogona kupatsanurwa kubva kune imwe mhete inotakura uye inoparadzaniswa.
Rudzi urwu rwekutakura rwuri nyore kuisa uye kupatsanura, kunyanya kana kupindira kwakakodzera pakati pemhete dzemukati nekunze, shaft uye goko rinodiwa. Rudzi urwu rwekutakura runowanzo shandiswa kutakura radial mitoro. Chete-mutsara mabhengi ane mbabvu pane ese emukati uye ekunze zvindori anogona kutakura madiki akatsiga axial mitoro kana yakakura inopindirana axial mitoro.
Mashandisirwo makuru: mahombe mota, muchina maturusi spindles, axle mabhokisi, dizeli injini crankshafts, mota, mabhokisi ekutapurirana ane mabearings, nezvimwe.
10 Mapoinzi mana ekusangana bhora mabearings
Inogona kutakura radial mutoro uye bidirectional axial mutoro. Iro rimwechete rinogona kutsiva iyo angular yekubata bhora inotakura yekumberi musanganiswa kana kumashure musanganiswa. Inokodzera kutakura pure axial load kana synthetic load nehombe axial load component. Mhando yekutakura iyi inogona kumira chero nzira. Imwe yemakona ekusangana inogona kuumbwa kana paine axial mutoro, saka iyo ferrule uye bhora zvinogara zvichisangana nemapoinzi matatu pamativi ese echero mutsara.
Kunyanya kushandiswa: ndege dzejeti injini, turbines gasi.
11 Kanda cylindrical roller bearings
Inosanganisira washer-shaped raceway ring (shaft ring, seat ring) uye cylindrical roller uye cage components. Iyo cylindrical roller inotora convex pamusoro pekugadzirisa, saka dzvinyiriro pakati pe roller uye nzvimbo yemujaho inogovaniswa zvakaenzana, uye inokwanisa kumira-imwe nzira axial mutoro. Iine yakakura axial mutoro simba uye yakasimba axial rigidity.
Kunyanya kushandiswa: oiri yekuchera rigs, iron uye simbi kugadzira michina.
12 Kupinza tsono roller bearing
Mabheji anopatsanurika anoumbwa nemhete dzemujaho, tsono rollers uye macage magungano, uye anogona kusanganiswa nekusarudzika neakadhindwa matete emujaho mhete kana akachekwa-akagadzirwa gobvu remujaho mhete. Mabhengi asinga patsanurwe ndiwo akabatanidzwa mabearings anoumbwa nechaizvo zvakadhindwa chidhindo chemujaho mhete, tsono rollers uye macage assemblies. Vanogona kumira unidirectional axial mitoro. Rudzi urwu rwekutakura runotora nzvimbo shoma uye inokodzera kune compact dhizaini yemuchina. Vazhinji vavo Chete chetsono roller nekeji gungano rinoshandiswa, uye iyo inokwirisa pamusoro peiyo shaft uye imba inoshandiswa seyemujaho wepamusoro.
Kunyanya kushandiswa: kutapurirana zvishandiso zvemotokari, varimi, maturusi emuchina, nezvimwe.
13 Kukanda tapered roller bearings
Rudzi urwu rwekubereka rwakashongedzerwa nema truncated cone-shaped rollers (iyo huru yekupedzisira ndeye spherical). Ma rollers anonyatso kutungamirirwa nembabvu dzemujaho mhete (shaft ring, seat ring). Iyo dhizaini inovimbisa kuti nzvimbo dzemujaho dze shaft mhete uye mhete yechigaro uye inotenderedza pamusoro peiyo rollers Iyo yepamusoro pega yega conical surface inopindirana pane imwe nzvimbo pamutsara wepakati wekubereka. Nzira imwe-yenzira inogona kutakura mitoro yenzira imwe chete, uye nzira mbiri dzinogona kutakura mitoro yenzira mbiri.
Chinangwa chikuru:
Imwe-nzira: Crane hook, mafuta ekuchera rig swivel.
Nzira mbiri: rolling mill roll neck.
14 Isai bhora rakatenderera nechigaro
Iyo yakagara spherical ball bearing inoumbwa nebhora rakatenderedzwa rine zvisimbiso pamativi ese uye cast (kana simbi ndiro yakadhindwa) chigaro chine chigaro. Chimiro chemukati chekunze spherical ball bearing chakafanana neicho cheyakadzika groove ball bearing, asi mhete yemukati yeiyi bheya yakakura kudarika yekunze. Mhete yekunze ine denderedzwa rekunze rekunze, iro rinokwanisa kuenderana neiyo concave spherical pamusoro pechigaro chekutakura.
Mashandisirwo makuru: migodhi, simbi, kurima, indasitiri yemakemikari, machira, kudhinda uye dhayi, michina yekufambisa, nezvimwe.
