Kodi Ma Roller Bearings Ndi Chiyani Kwenikweni?

Mapiritsi odzigudubuza, omwe amagwira ntchito mofanana ndi mayendedwe a mpira ndipo amatchedwanso ma roller-element bearings, ali ndi cholinga chimodzi: kunyamula katundu ndi mikangano yochepa. Zovala za mpira ndi zodzigudubuza ndizosiyana popanga komanso mawonekedwe. Ma cylinders amagwiritsidwa ntchito pomalizira pake, mosiyana ndi ma spheres akale, monga momwe zimakhalira zodzigudubuza ndi mayendedwe odzigudubuza.

Ma bearings okhala ndi zinthu zodzigudubuza amatha kukhala ndi mizere imodzi kapena iwiri ya odzigudubuza. Mizere yodzigudubuza ya mizere iwiri, mwachitsanzo, imawonjezera kunyamula katundu kwambiri. Kuphatikiza apo, kusinthika kwa ma bere awa mumasinthidwe ndi makulidwe osiyanasiyana kumathandizira kufalikira kosasunthika kwa ma radial ndi axial katundu.

 

Chifukwa Chiyani Ma Roller Bearings Amagwiritsidwa Ntchito?

Ma roller bearings amagwiritsidwa ntchito kwambiri kuti achepetse mikangano pazinthu zomwe zingapezeke. Izi zimapangitsa kuti pakhale kutentha pang'ono pamene zikugwiritsidwa ntchito ndipo zimachepetsa zofunikira zowonongeka. Zotsatirazi ndi zabwino zambiri zogwiritsira ntchito ma roller-element bearings:

Amachepetsa ndalama zogulira ndi kukonza

Mapangidwe olekanitsa, kupanga kukwera ndi kutsika kosavuta

Njira yomwe ingasinthidwe: Ogwiritsa ntchito amatha kusinthana mphete yamkati

Amaloleza kuyenda kwa axial

 

Mitundu ya Roller Bearings

1. Zozungulira zozungulira

Zigawo za chigawo chozungulira zimaphatikizapo mphete yakunja yokhala ndi njira yozungulira yozungulira, makola, zinthu zozungulira, ndipo, mwamapangidwe apadera, mphete zapakati. Mphete yamkati ili ndi mipikisano iwiri yopendekeka pamzere wonyamula.

2. Cylindrical Roller Bearings

Amabwera m'mizere imodzi kapena iwiri. Komabe, mosasamala kanthu za zomwe mumakonda, ma geometry awo amawapatsa mphamvu yonyamula ma radial apamwamba pamapulogalamu othamanga kwambiri. Komabe, amatha kupirira mitolo yocheperako.

3. Tapered Roller Bearings

Lingaliro la ma taper roller ndikuti ma cones azitha kugubuduzana popanda kutsetsereka. Amakhala ndi mizere yamagulu osasiyanitsidwa a cone okhala ndi mphete yamkati ndi yakunja. Ma conical raceways amathandizira ma bere odzigudubuza a conical tapered, omwe ali ndi mapangidwe opindika. Ma roller okhala ndi tapered amatha kupirira kupsinjika kwakukulu kwa ma radial, axial, ndi thrust chifukwa chakulumikizana kwawo kwakukulu; mapulogalamuwa amakhala pa liwiro lapakati.

4. Singano Roller Bearings

Kuthekera kwa zodzigudubuza za singano kugwiritsa ntchito malo okwererako ngati msewu wamkati kapena wakunja, kapena zonse ziwiri, ndiye mwayi wake waukulu. Kumangaku kumaperekanso malo osungiramo mafuta Akuluakulu, omwe amapangitsa kuti mapangidwe apangidwe akhale osavuta. Zodzigudubuza za singano zimapezeka ndi kapena popanda mphete yamkati.

5. Thrust Roller Bearing

Ma thrust bearings ndi mtundu wa mayendedwe opota omwe amagwiritsidwa ntchito kunyamula katundu wolemetsa pakakhala zovuta. Atha kukhala ndi zinthu zogudubuza zosiyanasiyana, monga singano, zopindika, zozungulira, kapena zozungulira, zomwe zimalekanitsa mphete zonyamula. Ma thrust rollers amalimbana ndi katundu omwe amakankhidwa ndikukokedwa motsatira mbali ya shaft. Liwiro lomwe angapite limadalira gawo logudubuza lomwe likugwiritsidwa ntchito.

 

Rmayendedwe a oller ndi gawo lofunikira pamakina amakina chifukwa amatsimikizira kuyendetsa bwino komanso kuchepetsa mikangano pamagwiritsidwe osiyanasiyana. Zofunikira zilizonse, chonde titumizireni ndikuchezera tsamba lathu: www.cwlbearing.com
