Mitundu iwiri ya mabearing omwe amagwiritsidwa ntchito kwambiri m'ma robot amafakitale

Maberani a magawo opyapyala ofanana ndimabearing ozungulira ozunguliraNdi magulu awiri akuluakulu omwe amagwiritsidwa ntchito popanga maloboti a mafakitale. Kuphatikiza apo, pali ma bearing a harmonic reducer, ma bearing a linear, ma bearing olumikizana, ndi zina zotero.

 

Magalimoto a ma robot a mafakitale ndi chimodzi mwa zinthu zofunika kwambiri, zomwe ndizoyenera kwambiri pa ntchito zosiyanasiyana monga ziwalo zolumikizirana kapena ziwalo zozungulira za ma robot a mafakitale, matebulo ozungulira a malo opangira makina, magawo ozungulira a manipulators, matebulo ozungulira molondola, zida zachipatala, zida zoyezera, ndi zida zopangira ma IC.

 

Makhalidwe a ma robot a mafakitale: amatha kupirira katundu wokwanira m'njira zozungulira, zozungulira, zopindika ndi zina; Ma berings opyapyala; Kulondola kwambiri kwa malo odulira. Bearing iliyonse yomwe ikukwaniritsa izi ingagwiritsidwe ntchito m'manja a robot a mafakitale, malo odulira, chassis, ndi zina zambiri.

 

1. Ma bereji ozungulira odutsa

Makhalidwe amabearing ozungulira opingasa: Ma crossed roller bearing ndi ma cylindrical rollers kapena ma tapered rollers pa malo ozungulira a V-shaped groove a madigiri 90 kudzera m'ma blocks odzipatula omwe amakonzedwa molunjika kwa wina ndi mnzake, kotero ma crossed roller bearing amatha kupirira katundu wosiyanasiyana monga radial load, axial load ndi torque load. Kukula kwa mphete zamkati ndi zakunja ndi kochepa, ndipo mawonekedwe ake ndi ochepa kwambiri, ndipo ali ndi kulimba kwakukulu, ndipo kulondola kumatha kufika pa P5, P4, ndi P2 levels. Chifukwa chake, ndi yoyenera magawo olumikizana ndi ozungulira a maloboti amafakitale, matebulo ozungulira m'malo opangira makina, matebulo ozungulira olondola, makina azachipatala, ma calculator, makampani ankhondo, zida zopangira IC, ndi zida zina.

 

1. Kulondola kwabwino kwambiri kwa kasinthasintha:

Kapangidwe ka mkati mwachogwirira chozungulira chozunguliraImagwiritsa ntchito ma rollers okonzedwa molunjika ndikuwoloka wina ndi mnzake pa 90°, ndipo ma rollers ali ndi zosungira zozungulira kapena zolekanitsa, zomwe zingalepheretse kuti ma rollers asakhudze wina ndi mnzake, ndikuletsa bwino kuwonjezeka kwa mphamvu yozungulira. Kuphatikiza apo, sipadzakhala kukhudzana kapena kutseka mbali imodzi ya rollers; Nthawi yomweyo, chifukwa mphete zamkati ndi zakunja zimagawika, malo otseguka amatha kusinthidwa, ndipo kuyenda kozungulira kolondola kwambiri kumatha kupezeka ngakhale mutagwiritsa ntchito prepressure.

 

2. Ntchito yosavuta komanso yoyika:

Mphete yakunja kapena yamkati, yomwe imagawidwa m'magawo awiri, imakhazikika pamodzi ma rollers ndi retainers atalumikizidwa, kotero kuyika kwake ndikosavuta kwambiri.

 

3. Kunyamula katundu waukulu wa axial ndi radial:

Popeza ma rollers amakonzedwa mopingasa ndi zosungira spacer pamalo ozungulira a V-groove pa 90°, kapangidwe kameneka kamalolamabearing ozungulira opingasakupirira katundu mbali zonse, kuphatikizapo katundu waukulu wa radial, axial ndi torque.

 

4. Sungani bwino malo oyika:

Kukula kwa mphete zamkati ndi zakunja za ma cross roller bearings kumachepetsedwa, ndipo makamaka, kapangidwe kake kowonda kwambiri kali pafupi ndi malire, ndipo kali ndi kulimba kwakukulu, kotero ndikoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, monga ziwalo zolumikizirana ndi magawo ozungulira a ma robot a mafakitale, matebulo ozungulira a malo opangira makina, magawo ozungulira a manipulators, matebulo ozungulira molondola, zida zachipatala, zida zoyezera, ndi zida zopangira IC.

 

2. Ma bereji owonda-khoma ofanana

Ma bearing a magawo ofanana opyapyala amapangidwa ndi mndandanda wotseguka asanu ndi awiri ndi mndandanda wotsekedwa asanu. Mndandanda wotseguka umapezeka m'mitundu itatu: mtundu wa radial contact C, mtundu wa angular contact A ndi mtundu wa X wolumikizana ndi mfundo zinayi. Ubwino wa ma bearing a magawo ofanana opyapyala: Ma bearing a magawo ofanana opyapyala amakhala ndi magawo owonda kwambiri, komanso amazindikira kuchepetsedwa kwa zinthu komanso kupepuka. Kusiyanasiyana kwa zinthu kumawonjezera ntchito zawo zosiyanasiyana.

Makhalidwe a zinthu za ma bearing opyapyala okhala ndi makoma ofanana: Kuti mupeze mphamvu yochepa ya friction, kulimba kwambiri komanso kulondola kozungulira kwa bearing, mipira yachitsulo yokhala ndi mainchesi ang'onoang'ono akunja imagwiritsidwa ntchito. Kugwiritsa ntchito ma shafts opanda kanthu kumatsimikizira kulemera kopepuka ndi malo olumikizirana. Ma 6700 ndi 6800 opyapyala okhala ndi makoma ochepa ali ndi mitundu yosiyanasiyana ya fumbi, mitundu yopyapyala, mitundu ya chitsulo chosapanga dzimbiri, mitundu yotakata m'lifupi, ndi zina zotero, yokhala ndi mitundu yonse.

 

Kugwiritsa ntchito kwakukulu kwa ma bearing okhala ndi makoma ochepa komanso ofanana: ma stepper motors, zida zachipatala, zida zaofesi, zida zoyesera, zida zochepetsera liwiro/zosinthasintha, maloboti amafakitale, zida zowunikira/zojambula, zolembera zozungulira.

 

Ma bearing a ma ferrule opyapyala, omwe amadziwikanso kuti ma bearing a ferrule opyapyala, ali ndi kulondola kwakukulu, ndi chete kwambiri ndipo ali ndi mphamvu yonyamula katundu wamphamvu. Ma bearing a ferrule opyapyala amatha kukhalamaberamu a mpira wozama kwambiri, ma bearing a contact-point four-point, ma bearing a angular contact ball, ndi ma cross-sectional cross-sectional a ma bearing-walled walls ndi a square. Mu mndandanda uwu, cross-section imakhalabe yofanana ngakhale ndi ma shaft diameter akuluakulu ndi ma bearing bores. Chifukwa chake ma bearing awa amatchedwa ma equal section. Ndi khalidweli lomwe limasiyanitsa ma thin section ferrule bearing ndi ma bearing achikhalidwe mu standard ISO series. Chifukwa chake, ma cross-section akuluakulu amatha kusankhidwa ndipo ma bearing okhala ndi mphamvu yayikulu yonyamula katundu angagwiritsidwe ntchito popanda kusintha shaft diameter. Ma thin-section ferrule bearing amatha kupangidwa kuti akhale ma bearing opepuka kwambiri omwe amafunikira malo ochepa.
