Bearings chinhu chakakosha chemichina yemazuva ano. Basa rayo guru ndere kutsigira mechanical inotenderera muviri, kuderedza friction coefficient panguva yekufamba kwayo, uye kuve nechokwadi chekutenderera kwayo.
Zvinoenderana neyakasiyana friction properties yezvinofamba zvinhu, mabearings anogona kupatsanurwa muzvikamu zviviri: rolling bearing and sliding bearings.
Inowanzo shandiswa mukutenderedza mabearings akadzika groove bhora mabearings, cylindrical roller mabearings uye thrust ball bearings. Pakati pawo, mabhengi anotenderedzwa akamisikidzwa uye akaiswa serialized, uye anowanzo kuumbwa nezvikamu zvina: mhete yekunze, mhete yemukati, inotenderedza muviri uye keji.
Deep groove ball bearingskunyanya kutakura radial mutoro, uye inogona zvakare kutakura radial mutoro uye axial mutoro panguva imwe chete. Kana ichingoiswa pasi pe radial mutoro, iyo yekubata angle ndeye zero. Kana iyo yakadzika groove bhora inotakura ine yakakura radial clearance, ine kuita kweangular yekubata inotakura uye inogona kutakura yakakura axial mutoro. Iyo friction coefficient yeyakadzika groove bhora inotakura idiki kwazvo uye yekumisikidza kumhanya yakakwira zvakare.
Deep groove ball bearings ndiwo anomiririra kutenderedza mabearings uye anoshandiswa zvakanyanya. Inokodzera kukwirisa uye kunyangwe yakanyanyisa kumhanya mashandiro, uye yakasimba kwazvo pasina kugara ichigadzirisa. Iri rudzi rwekubereka rine diki friction coefficient, yakakwira muganho kumhanya, yakapusa chimiro, yakaderera mutengo wekugadzira uye nyore kuwana yakakwirira yekugadzira chaiyo. Saizi yemhando uye fomu inosiyana, uye anoshandiswa mune chaiyo zviridzwa, yakaderera-ruzha mota, mota, midhudhudhu nemichina yakawanda uye mamwe maindasitiri, uye ndiyo inonyanya kushandiswa mhando yemabhengi muindasitiri yemuchina. Kunyanya takura radial mutoro, asi zvakare takura humwe huwandu hweaxial mutoro.
Cylindrical roller bearings, iyo inotenderedza zvinhu ndeye radial rolling mabearings emacylindrical rollers. Cylindrical rollers uye mijaho mitsetse yekubatanidza mabhengi. Kutakura huwandu, kunyanya kutakura radial mutoro. Iko kukakavara pakati pechinhu chinoputika uye mbabvu yemhete idiki, iyo yakakodzera kutenderera-kumhanya. Zvinoenderana nekuti mhete ine mbabvu here kana kuti kwete, inogona kupatsanurwa kuita mitsara imwechete seNU, NJ, NUP, N, NF, uye mitsetse miviri yakaita seNNU neNN.
Cylindrical roller bearings pasina mbabvu pane yemukati kana yekunze mhete, mukati uye kunze zvindori zvinogona kufamba maererano neaxial direction, saka inogona kushandiswa sekusununguka kwekupedzisira. Cylindrical roller bearings ine mbabvu mbiri kune rumwe rutivi rwemhete yemukati uye yekunze mhete uye imwe mbabvu kune rumwe rutivi rwemhete inogona kumira imwe chiyero cheaxial mutoro mune imwe nzira. Kazhinji, simbi yekutsika keji inoshandiswa, kana simbi yemhangura inoshandura yakasimba keji inoshandiswa. Nekudaro, kune zvakare chikamu chekushandiswa kwepolyamide kugadzira cage.
Mabhora eTrust akagadzirirwa kushingirira mitoro panguva yekumhanya-mhanya, uye anosanganisira washer-kunge maferrules ane mijaho mijaho yekutenderedza bhora. Sezvo ferrule iri muchimiro chechigaro chechigaro, bhora rekusimudzira rakakamurwa kuva mhando mbiri: flat seat cushion type uye self-aligning spherical seat cushion type. Mukuwedzera, iyi kutakura inogona kumira axial mitoro, asi kwete radial mitoro.
Kanda bhoraanoumbwa nezvikamu zvitatu: chigaro washer, shaft washer uye simbi bhora keji musangano. Shaft washer inofananidzwa neshaft uye ring yechigaro ichienderana neimba. Thrust ball bearings akakodzera chete zvikamu zvinotakura axial load kune rimwe divi uye zvine low speed, senge crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft washer, seat washer uye rolling element. yekutakura inoparadzaniswa uye inogona kuunganidzwa uye kuparadzaniswa zvakasiyana.
