Chilichonse Chimene Muyenera Kudziwa Zokhudza Roller Bearings

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.

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

Ma bearings amatha kuwongolera kusintha kwamayendedwe popanda kufunikira kusintha kwaukadaulo.

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.

Chifukwa cha kusinthasintha kwake komanso kupezeka kwake mu makulidwe a cylindrical kapena tapered bore kuyambira 20 mm mpaka 900 mm, zozungulira zozungulira zitha kukhazikitsidwa ndi adapta ya manja kapena popanda.https://www.cwlbearing.com/spherical-roller-bearings/

 

2. Cylindrical Roller Bearings

Ngakhale kuti si masilindala, ma fani awa ali ndi zodzigudubuza zooneka ngati cylindrical zomwe zimalumikizana ndi mipikisano yothamanga. Kuti achepetse kupsinjika, amakhala ndi malekezero oyandama kapena okhala ndi korona. Amabwera m'mizere imodzi kapena iwiri. Komabe, mosasamala kanthu zomwe mumakonda, ma geometry awo amawapatsa mwayi wokweza ma radial pamapulogalamu othamanga kwambiri. Komabe, amatha kupirira mitolo yocheperako.

3. Tapered Roller Bearings

Ma taper rollers amakhala ndi mizere yamagulu osagwirizana ndi ma cone okhala ndi mphete yamkati ndi yakunja. Ma conical raceways amathandizira ma bere odzigudubuza a conical tapered, omwe ali ndi mapangidwe opindika. ma tapered roller bearings amabwera mu inchi ndi kukula kwa metric.

Ngakhale amawoneka ngati ma cylindrical bearings, kusiyana kwakukulu pakati pawo ndikuti ma cylindrical roller bearings amatha kupirira kupsinjika kwakanthawi kochepa. Zofanana zawo za tapered zimathanso kunyamula katundu wamkulu. Zambiri, chonde onani tsamba lathu:https://www.cwlbearing.com/taper-roller-bearings/

 

4. Singano Roller Bearings

 

Zodzigudubuzazi zimakhala ndi zimbalangondo zazitali, zoonda zomwe zimayikidwa mopingasa mkati mwa chipolopolocho. Atha kukhala ndi malekezero a hemispherical akuyenda mopanda malire kapena malekezero opindika kuti chogudubuza chikhalepo. Mtundu wa cylindrical bearing ndi singano.

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.

Themayendedwe odzigudubuza ndi gawo lofunikira pamakina amakina chifukwa amatsimikizira kuyendetsa bwino komanso kuchepetsa mikangano pamagwiritsidwe osiyanasiyana.
