Chilichonse Chomwe Muyenera Kudziwa Zokhudza Ma Roller Bearings

Ma roller bearing, omwe amagwira ntchito mofanana ndi ma ball bearing ndipo amatchedwanso ma roller-element bearing, ali ndi cholinga chimodzi: kunyamula katundu ndi kupsinjika kochepa. Ma ball bearing ndi ma roller bearing ndi osiyana mu kapangidwe ndi mawonekedwe. Ma cylinders amagwiritsidwa ntchito kumapeto, mosiyana ndi ma sphere mu oyamba, monga mu ma cross roller bearing ndi linear roller bearing.

Mabearing okhala ndi zinthu zozungulira amatha kukhala ndi mizere imodzi kapena iwiri ya ma rollers. Mwachitsanzo, ma bearing a mizere iwiri amawonjezera kwambiri kunyamula katundu wa radial. Kuphatikiza apo, kusinthasintha kwa ma bearing awa m'makonzedwe ndi miyeso yosiyanasiyana kumathandiza kutumiza popanda kukangana kwa katundu wa radial ndi axial.

Ubwino wogwiritsa ntchito ma roller-element bearings ndi awa:

Amachepetsa ndalama zokonzera ndi kukonza

Kapangidwe kolekanitsidwa, zomwe zimapangitsa kuti kuyika ndi kuchotsa kukhale kosavuta

Njira yosinthira: Ogwiritsa ntchito amatha kusintha mphete yamkati

Mabearing angathandize kusintha kwa njira popanda kufunikira kusintha kwaukadaulo.

Imalola kuyenda kwa axial

Mitundu ya Ma Roller Bearings:

1. Mabearings Ozungulira Ozungulira

Zigawo za chozungulira chozungulira zimaphatikizapo mphete yakunja yokhala ndi msewu wozungulira wozungulira, zikwama, zinthu zozungulira zozungulira, ndipo, m'mapangidwe enaake, mphete zapakati. Mphete yamkati ili ndi njira ziwiri zothamangira zomwe zapendekeka pa mzere wozungulira.

Chifukwa cha kusinthasintha kwake komanso kupezeka kwake m'mabowo ozungulira kapena opindika kuyambira 20 mm mpaka 900 mm, ma bearing ozungulira ozungulira amatha kuyikidwa ndi kapena popanda adaputala yamanja. Yang'anani zambiri za bearing:https://www.cwlbearing.com/spherical-roller-bearings/

 

2. Mabearings a Cylindrical Roller

Ngakhale si ma cylinder, ma bearing awa ali ndi ma rollers ofanana ndi cylinder omwe amalumikizana ndi mipikisano. Kuti achepetse kupsinjika, amakhala ndi malekezero oyandama kapena okhala ndi korona m'malo mwake. Amabwera m'mizere imodzi kapena iwiri. Komabe, mosasamala kanthu za zomwe mumakonda, mawonekedwe awo amawapatsa mphamvu yayikulu yonyamula ma radial mu ntchito zothamanga kwambiri. Komabe, amatha kupirira katundu wochepa. Ma bearing ambiri amapangidwa:https://www.cwlbearing.com/cylindrical-roller-bearings/

 

3. Mabearings Ozungulira Opindika

Ma rollers a taper amakhala ndi mizere ya ma cone assemblies osalekanitsidwa okhala ndi mphete yamkati ndi yakunja. Misewu ya conical raceways imathandizira ma rollers a conical tapered, omwe ali ndi mapangidwe ofooka. Ma rollers a tapered amabwera mu kukula kwa mainchesi ndi metric.

Ngakhale kuti amaoneka ngati ma bearing a cylindrical, kusiyana kwakukulu pakati pawo ndikuti ma bearing a cylindrical roller amatha kupirira kupsinjika kwa kukakamiza pang'ono. Ma bearing awo ocheperako amathanso kuthana ndi katundu wolemera wokakamiza. Zambiri, chonde onani tsamba lathu la intaneti:https://www.cwlbearing.com/taper-roller-bearings/

 

4. Mabearing a Singano

 

Ma rollers awa ali ndi ma bearing aatali komanso owonda omwe amakonzedwa mopingasa mkati mwa chipolopolo cha bearing. Akhoza kukhala ndi malekezero a hemispherical kuti ayende mopanda malire kapena malekezero ocheperako kuti asunge bearing pamalo pake. Mtundu wa bearing yozungulira ndi singano.

Mphamvu ya ma needle rollers kugwiritsa ntchito malo olumikizirana ngati msewu wamkati kapena wakunja, kapena zonse ziwiri, ndiye phindu lake lalikulu. Kapangidwe kake kamaperekanso malo akuluakulu osungira mafuta, zomwe zimapangitsa kuti kapangidwe kake kakhale kosavuta. Ma needle rollers amapezeka ndi mphete yamkati kapena yopanda.

5. Kunyamula Roller

Ma thrust bearing ndi mtundu wa thrust bearing yomwe imagwiritsidwa ntchito kunyamula katundu wolemera m'mikhalidwe yovuta. Amatha kukhala ndi zinthu zosiyanasiyana zozungulira, monga singano, zopindika, zozungulira, kapena zozungulira, zomwe zimalekanitsa mphete zogwirira. Ma thrust rollers amagwira ntchito ndi katundu amene amakankhidwa ndikukokedwa motsatira mzere wa shaft. Liwiro lomwe angapite limadalira gawo lozungulira lomwe likugwiritsidwa ntchito.

TheMa roller bearing ndi gawo lofunikira kwambiri pa makina chifukwa amatsimikizira kuti akuyenda bwino komanso amachepetsa kukangana pa ntchito zosiyanasiyana.
