Chii chinonzi Bearing?

Bearings zvinhu zvemuchina zvakagadzirirwa kutsigira mashaft anotenderera, kuderedza kukwenya, uye kutakura mitoro. Nekudzikisa kupokana pakati pezvikamu zvinofamba, mabhengi anogonesa kufamba kwakapfava uye kunoshanda, kunowedzera kushanda uye hupenyu hurefu hwemuchina. Bearings anowanikwa mune zvisingaverengeki maapplication, kubva kumota injini kuenda kumaindasitiri emuchina.

Shoko rokuti “kubereka” rinobva pashoko rechiito rokuti “kubereka,” richireva chinhu chomuchina chinoita kuti chimwe chikamu chitsigire chimwe. Iyo inonyanya kukosha yemhando yemabhengi inosanganisira inobereka nzvimbo dzakaumbwa kana kuisirwa muchikamu, ine nhanho dzakasiyana dzehutsanana maererano nechimiro, saizi, roughness, uye kuiswa kwepasi.

Mabasa eBearings :

Deredza Kukurumbira: Bearings inoderedza kupokana pakati pezvikamu zvinofamba, izvo zvinovandudza kushanda zvakanaka uye hupenyu hurefu hwemakina.

Kutsigira Mutoro: Bearings inotsigira zvose radial (perpendicular to the shaft) uye axial (yakafanana kune shaft) mitoro, kuve nechokwadi chekugadzikana.

Wedzera Kurongeka: Nekudzikisira kutamba uye kuchengetedza kurongeka, mabheji anosimudzira iko chaiko kwemuchina.

Bearing Materials :

Simbi: Iyo inonyanya kufarirwa zvinhu nekuda kwesimba rayo uye kusimba.

Ceramics: Inoshandiswa kune yakakwirira-kumhanya kunyorera uye nharaunda dzine tembiricha yakanyanyisa.

Plastics: Inokodzera kureruka uye inoora nharaunda.

Mujaho Wemukati (Inner Ring)

Mujaho wemukati, unowanzonzi rin'i yemukati, inhengo yeberengi inonamira paburi rinotenderera. Iine groove yakatsetseka, yakanyatsogadzirwa-muchina apo zvinhu zvinokunguruka zvinofamba. Sezvo kubereka kunoshanda, mhete iyi inotenderera pamwe chete neshaft, inobata masimba anoshandiswa panguva yekushandiswa.

Mujaho Wekunze (Outer Ring)

Kune rimwe divi kune nhangemutange yekunze, iyo inowanzogara yakamira mukati meimba kana muchina chikamu. Kufanana nenhangemutange yemukati, inewo mukoto, unozivikanwa semujaho, panogara zvinhu zvinokunguruka. Rudzi rwekunze runobatsira kuendesa mutoro kubva kune zvinotenderera zvinhu kuenda kune imwe yakasara yechimiro.

Rolling Elements

Aya ndiwo mabhora, ma roller, kana tsono dzinogara pakati pemakwikwi emukati nekunze. Chimiro chezvinhu izvi zvinoenderana nemhando yekutakura. Mabhora ebhora anoshandisa mabhora akaita spherical, ukuwo ma roller bearings anoshandisa macylinders kana tapered rollers. Zvinhu izvi ndizvo zvinobatsira kuderedza kupokana uye kubvumira kutenderera kwakatsetseka.

Cage (Retainer)

Iyo keji chikamu chinowanzo tariswa asi chakakosha chikamu chekutakura. Inobatsira kuchengetedza zvinhu zvinotenderedza zvakaenzana pazvinofamba, zvichidzivirira kuti dzisabatana pamwe nekuchengetedza kushanda zvakanaka. Makeji anogadzirwa kubva kune zvinhu zvakaita sesimbi kana epurasitiki, zvichienderana nerudzi rwekutakura uye kushandiswa kwayo.

Zvisimbiso uye Nhoo

Izvi zvinhu zvinodzivirira. Zvisimbiso zvakagadzirirwa kuchengetedza zvinosvibisa zvakaita setsvina uye hunyoro kubva pakutakura, uchichengeta lubrication mukati. Nhovo dzinoita basa rakafanana asi dzinobvumira rusununguko rushoma rwekufamba. Zvisimbiso zvinowanzo shandiswa munzvimbo dzakaoma, nepo nhovo dzichishandiswa uko kusvibiswa kusinganyanyi kunetseka.

Lubrication

Mabearings anoda lubrication kuti ashande nemazvo. Ingave girisi kana mafuta, lubrication inoderedza kupokana pakati pezvikamu zvinofamba uye zvinobatsira kudzivirira kusakara. Inobatsirawo mukutonhodza kutakura, iyo inogona kuva yakakosha mu-high-speed applications.

Raceway

Mujaho wemujaho ndiwo mukoto mumijaho yemukati nekunze uko zvinhu zvinokunguruka zvinofamba. Nzvimbo iyi inofanirwa kunyatsogadzirwa kuti ive nechokwadi chekufamba kwakatsetseka uye kugovanisa mitoro.
