Pali zinthu 6 zofunika kuziganizira posankha mabearing a zida zoziziritsira

 

Mitundu yonse ya mabearing ozungulira ili ndi makhalidwe osiyanasiyana ndipo ndi oyenera kugwiritsidwa ntchito m'makina osiyanasiyana. Nthawi zonse,mabearing oponderezedwa ndi mabearing olumikizana ndi angularamasankhidwa akanyamula katundu wokankhira;

 

Mabeya a mpiranthawi zambiri amagwiritsidwa ntchito poyendetsa mwachangu kwambiri, ndipo ma roller bearing amagwiritsidwa ntchito poyendetsa katundu wolemera wa radial.

 

1. Malo ndi malo a makina omwe ali ndichogwirira

 

Pakupanga makina, kukula kwa shaft nthawi zambiri kumatsimikiziridwa kaye, kenako chogwirira chozungulira chimasankhidwa malinga ndi kukula kwa shaft. Ma bearing a mpira nthawi zambiri amagwiritsidwa ntchito pa ma shaft ang'onoang'ono ndi ma roller bearing a ma shaft akuluakulu. Komabe, pamene chogwiriracho chili ndi malire mu diameter ya makina,mabearing a singano, mipira kapena mabearing a roller a zowonjezera kuwala ndi ultra-light mndandanda amasankhidwa; Pamene malo a axial a bearing mu makina ali oletsedwa, mndandanda wopapatiza kapena wopapatiza kwambiri wa mabearing a mpira kapena ma roller amapezeka.

 

2. Kukula, komwe katundu ali, ndi mtundu wake

 

Katundu ndiye chinthu chofunikira kwambiri pakusankha ma bearing. Ma roller bearing amagwiritsidwa ntchito kupirira katundu wolemera, ma ball bearing amagwiritsidwa ntchito kupirira katundu wopepuka kapena wapakati, ndipo ma bearing opangidwa ndi chitsulo chosungunuka kapena bainite chozimitsidwa amapangidwa kuti apirire katundu wogwedezeka ndi kugwedezeka.

 

Ponena za momwe katunduyo amagwirira ntchito, ponyamula katundu wozungulira wokha, ma bearing a mpira wozama, ma bearing a cylindrical roller kapena ma bearing a singano angasankhidwe. Ponyamula katundu wozungulira wokha, ma bearing a mpira wothira angasankhidwe; Ma bearing a Thrust roller amapezeka pa katundu waukulu wozungulira wokha. Pamene bearing ikukhudzidwa ndi katundu wozungulira wokha komanso wozungulira, ma bearing a angular contact ball kapena ma bearing a tapered roller nthawi zambiri amagwiritsidwa ntchito.

 

3.Kugwira ntchito kodzigwirizanitsa kwa chogwirira

 

Pamene mzere wapakati wa shaft uli wosiyana ndi mzere wapakati wa bearing housing, pamakhala cholakwika cha angular, kapena chifukwa chakuti mtunda pakati pa zothandizira ziwiri za shaft ndi waukulu ndipo kulimba kwa shaft ndi kochepa, n'kosavuta kupindika kapena kupendekeka pansi pa mphamvu, mpira wodzilungamitsa kapena bere lodzilungamitsa lokha lomwe limagwira ntchito bwino komanso bearing yakunja ya mpira ikhoza kusankhidwa. Mabere awa amakhalabe ogwira ntchito bwino ngati shaft yapendekeka pang'ono kapena yopindika.

 

Ubwino wa magwiridwe antchito a bearing self-alignment umagwirizana ndi kusiyana kwa ma axiality komwe kumalola, ndipo phindu la ma axiality osiyanasiyana likakula, magwiridwe antchito a self-alignment amakhala abwino.

 

4. Kulimba kwa chogwirira

 

Kulimba kwa bearing kumatanthauza kuchuluka kwa mphamvu yomwe imafunika kuti bearing ipange kusintha kwa unit. Kusinthika kwa elastic kwa ma rolling bearing ndi kochepa kwambiri, ndipo sikofunikira kuganizira izi mu makina ambiri, koma mu makina ena, monga ma spindles a machine tool, kulimba kwa bearing ndi chinthu chofunikira, ndipo ma bearing a cylindrical ndi tapered roller ayenera kusankhidwa nthawi zambiri. Chifukwa mitundu iwiriyi ya ma bearing imakhudzana ndi raceway pamene ili pansi pa katundu, kulimba kwake kumakhala koipa.

 

Kuphatikiza apo, mitundu yonse ya ma bearing imathanso kuyikidwa pasadakhale kuti ikwaniritse cholinga chowonjezera kulimba kwa chithandizo. Mwachitsanzo,mabearing a mpira wolumikizana ndi angularndi ma tapered roller bearing, pofuna kupewa kugwedezeka kwa shaft ndikuwonjezera kulimba kwa chithandizo, mphamvu inayake ya axial nthawi zambiri imagwiritsidwa ntchito pasadakhale panthawi yoyika kuti zigwirizane. Ndikofunikira kudziwa apa kuti kuchuluka kwa katundu woyambirira sikuyenera kukhala kwakukulu kwambiri. Ikakhala yayikulu kwambiri, kukangana kwa bearing kumawonjezeka, kutentha kumakwera, ndipo moyo wa bearing umakhudzidwa.

 

5. Liwiro lozungulira la chogwirira

 

Mtundu uliwonse wa bearing uli ndi liwiro lake lokhazikika, lomwe limatsimikiziridwa ndi mawonekedwe akuthupi monga kukula, mtundu ndi kapangidwe kake, liwiro lokhazikika limatanthauza liwiro lalikulu logwira ntchito la bearing (nthawi zambiri r/min), kupitirira malire awa kungapangitse kutentha kwa bearing kukwera, mafuta odzola kuuma, komanso kupangitsa bearing kulephera. Liwiro lofunikira pakugwiritsa ntchito limathandiza kudziwa mtundu wa bearing woti ugwiritse ntchito. Opanga ambiri bearing amapereka liwiro lokwanira la zinthu zawo m'makatalogu awo azinthu, ndipo machitidwe awonetsa kuti ndi bwino kugwira ntchito pamalo ochepera 90% ya liwiro lokhazikika.

 

Kawirikawiri, pa ntchito yothamanga kwambiri, ndibwino kusankha ma bearing a mpira wozama kwambiri, ma bearing a angular contact, ndi ma bearing a cylindrical roller; Pa liwiro lotsika, ma bearing a tapered roller ndi osankha. Liwiro lomaliza la ma bearing a tapered roller nthawi zambiri limakhala pafupifupi 65% ya ma bearing a mpira wozama kwambiri, 70% ya ma bearing a cylindrical roller, ndi 60% ya ma bearing a angular contact ball. Ma bearing a mpira wothamanga ali ndi liwiro lotsika ndipo angagwiritsidwe ntchito pa liwiro lotsika.

 

6. Ndi yabwino kukhazikitsa ndi kusokoneza ma bere

 

Posankha mtundu wa bearing, ndikofunikiranso kuganizira ngati bearing ndi yosavuta kuyiyika ndikuyichotsa, makamaka poyika ndi kusokoneza ma bearing akuluakulu ndi akuluakulu kwambiri. Ma bearing a mpira wolumikizana ndi angular, ma bearing a roller opindika, ma bearing a cylindrical roller ndi ma bearing a singano okhala ndi mphete zakunja zolekanitsidwa ndizosavuta kuyiyika ndikuyichotsa, ndipo mphete zawo zamkati ndi zakunja zitha kuyikidwa pa shaft kapena mu housing bore motsatana. Kuphatikiza apo, ma bearing a spherical roller okhala ndi bore yopindika ndi adapter sleeve, ma bearing a cylindrical roller opindika awiri ndi ma bearing a mpira opindika ndi osavuta kuyiyika ndikuyichotsa.
