Mabearing ndi "malumikizidwe" a makina.

 

Mabeyandi "zolumikizira" za makina, zomwe zimagwiritsidwa ntchito pothandizira mipata yozungulira.

 

Amagawidwa m'magulu awiri akuluakulu: ma bearing ozungulira ndi ma bearing otsetsereka.

 

Ma bearing ofananaZili ndi magawo anayi: mphete yakunja, mphete yamkati, zinthu zozungulira, ndi khola.

 

Zinthu zozungulira, monga mipira yaying'ono kapena ma rollers, zimazungulira pakati pa mphete zamkati ndi zakunja, zomwe zimachepetsa kukangana mu makina. Izi zimapangitsa makina kuyenda bwino.

 

Kumvetsetsa bwino kapangidwe kake ndi magulu a ma bearing kungatithandize kusamalira bwino makina athu:

 

1. Zigawo zinayi zazikulu za chogwirira:

Mphete yamkati: Imakwanira bwino pa shaft yozungulira ya makina ndipo imazungulira pamodzi.

 

Mphete yakunja: Yokhazikika m'nyumba yosungiramo bere, yopereka chithandizo.

 

Zinthu zozungulira: Zipindani pakati pa mphete zamkati ndi zakunja. Zimabwera mu mawonekedwe monga ozungulira (mipira) ndi ozungulira (ozungulira kapena ozungulira).

 

Khola: Limalekanitsa zinthu zozungulira, kuti zisakhudzene ndi kugundana.

 

2. Kugawa ndi malangizo a katundu:

Maberiyali ozungulira: Makamaka mphamvu za bear zimangoyang'ana molunjika ku shaft. Mwachitsanzo, maberiyali a mpira wozama.

Maberiya othyola: Makamaka amakhala ndi mphamvu zofanana ndi shaft (mphamvu ya axial). Maberiya othyola: Amatha kupirira mphamvu zoyima komanso zofanana nthawi imodzi.

 

3. Maberiyani otsetsereka poyerekeza ndi maberiyani ozungulira: Maberiyani ozungulira: Kukhudzana ndi chinthu chozungulira, kupsinjika kochepa, kusunga mphamvu, kosavuta kulinganiza ndi kugula. Nthawi ya moyo ikhoza kunenedweratu pogwiritsa ntchito ma formula (monga kuwerengera moyo wa L₁₀). Maberiyani otsetsereka: Kukhudzana pamwamba ndi filimu yamafuta opaka pakati. Kulemera kwakukulu, nthawi yayitali ya moyo, yomwe imagwiritsidwa ntchito kwambiri mumakina olemera.

 

Zinthu zitatu zofunika kwambiri pa khalidwe la bere:

 

Kusankha zinthu: Chitsulo chapamwamba kwambiri chili ndi kuuma kwakukulu komanso kukana kuwonongeka, zomwe zimawonjezera nthawi yogwira ntchito.

 

Kulondola kwa makina: Kutha kwa pamwamba pa mphete zamkati ndi zakunja ndi zinthu zozungulira kumakhudza mwachindunji kusalala kwa ntchito.

 

Kupaka mafuta: Mafuta oyenera amachepetsa kukangana, amachepetsa kutentha kwa ntchito, komanso amawongolera magwiridwe antchito.

 

Zofunikira zazikulu zaukadaulo zamaberiya:

Zofunikira zaukadaulo ndiye maziko a kapangidwe ndi kupanga ma bearing. Makamaka zimaphatikizapo kulekerera kwa miyeso, kulondola kozungulira, kuchotsera, kugwedezeka, ndi phokoso. Magawo awa ayenera kutsimikiziridwa kutengera momwe ntchito ikuyendera. Mwachitsanzo, zida zolondola zimafuna kulondola kozungulira kwambiri, pomwe makina olemera amayang'ana kwambiri mphamvu yonyamula katundu.
