Maberani a makina a zaulimi

Padziko lonse lapansi, mosasamala kanthu za nyengo kapena kukolola kwa mbewu, kugwiritsa ntchito zinthu zodalirika komanso zolimba ndi chinthu chofunikira kwambiri pakuwonetsetsa kuti makina a ulimi akusamalidwa bwino ndikukololedwa munthawi yake.

 

Maberani a makina a zaulimiNdi zigawo zofunika kwambiri pa makina ndi zida zaulimi, zomwe zimagwiritsidwa ntchito kwambiri m'magalimoto aulimi, mathirakitala, mainjini a dizilo, ma mota amagetsi, ma rake a udzu, ma baler, okolola, zopunthira ndi makina ena aulimi, kulondola kwake, magwiridwe antchito, moyo ndi kudalirika kwake zimagwira ntchito yofunika kwambiri pa kulondola, magwiridwe antchito, moyo ndi kudalirika kwa injini yayikulu.

 

Mabearing ayenera kukhala okhoza kugwira ntchito m'malo ovuta, kuyambira ouma ndi owuma mpaka malo onyowa, owononga, komanso oipitsidwa kwambiri, ndikukwaniritsa zofunikira kuti zikhale zolimba komanso zokhalitsa kuti zikwaniritse zovuta zomwe alimi amakumana nazo kuti achepetse nthawi yogwira ntchito komanso ndalama zosamalira ndikuwonjezera phindu.

 

Makhalidwe amabearing a makina a zaulimi

 

1. Imatha kupirira kugwedezeka kosalekeza komanso katundu wolemera kwambiri;

 

2. Kapangidwe kotseka mosamala komanso kolondola kwambiri kuti kagwire ntchito modalirika pa nyengo zosiyanasiyana;

 

3. Kapangidwe kosamalidwa bwino kapena kosakonzedwa bwino;

 

4. Yosavuta kukhazikitsa, imapereka gawo lofunikira;

 

5. Kapangidwe ka nyumba ndi kosavuta kwambiri;

 

6. Onetsetsani kuti makinawo akugwiritsidwa ntchito bwino;

 

Palinso mitundu yambiri ya zida mu makina a zaulimi, nthawi yogwiritsira ntchito ndi momwe amagwiritsidwira ntchito ndi yosiyana, kotero ma bearing omwe amagwiritsidwa ntchito nawonso ndi osiyana, ma bearing omwe amagwiritsidwa ntchito kwambiri mu makina a zaulimi ndi awa: ma bearing a mpira wa makina a zaulimi (dzenje lozungulira, dzenje lalikulu kapena dzenje la hexagonal, mphete yotseka, dzenje la mafuta lotha kudzozedwanso kapena nozzle yamafuta), bearing ya mpira wolumikizana ndi angular, bearing yozungulira, bearing ya singano, bearing ya roller yopapatiza, ndi zina zotero.

 

Makina olima ndi obzala mbewu

 

Chinyezi chambiri nthawi ya masika ndi nthawi yophukira ndi mayeso enieni a ulimi, ndipo nthaka yolimba imayesa mphamvu zonse za makina, zomwe zimafuna mphamvu yolimba ya ma bearing a makina a ulimi.

 

Maberiya a makina olimanthawi zambiri amaphatikizidwa ndi zitseko zokhala ndi ma flange kuti zikhale zosavuta kusonkhana. Mwachitsanzo, diski ya pulawo imalumikizidwa ndi bearing, yomwe imayikidwa pamwamba pa pulawo ndi ngodya inayake yopendekera, ndipo bearing imafunika kunyamula katundu wa mbali, kutembenuza nthawi ndi katundu wa radial.

 

Gawo lothandizira limaphatikizapo:

 

Ma bearing a mpira wolumikizana ndi mizere iwiri, ochokera ku mndandanda wa magalimoto okhala ndi mawilo - mphamvu yayikulu yonyamula katundu, kuuma kwa ma roll, kutseka mbali ziwiri;

 

Zipinda zosungiramo zinthu zopangidwa ndi makina zotetezedwa ndi dzimbiri;

 

mapini olumikizidwa okhala ndi malo owunikira;

 

Ma washer oletsa kumasula.

 

Zinthu zomwe zimagwiritsidwa ntchito mu makina olima ndi monga ma bearing a mpira ozungulira ndi ma unit okhala, ma bearing a mpira wozama wotsekedwa ndi ma bearing a mpira wolumikizana ndi angular, ma bearing a roller opendekeka, ma bearing a hexagonal ndi square bore, komanso ma unit a idler ndi ma unit a chain drive idler tooth.

 

mathirakitala

 

Ma bere ndi zigawo zina zotumizira

 

Katundu wamkulu wa radial ndi axial, mabearings a cylindrical roller opanda mphete zakunja ndi oyenera makamaka ma gearbox a planetary.

 

Ma tapered roller bearing ndi oyenera ma hydraulic motors, ma hydraulic pumps, ma gearbox bevel shaft bearing ndi ma rear axle drives ophatikizidwa ndi ma gearbox.

 

Mapulogalamu mu chassis

 

Lamba wakunja wogwiritsiridwa ntchito pamalo olumikizirana a masika a axle yakutsogolo ya chassis umangopaka mafuta olumikizirana a dongosolo;

 

Mabeya a kiyi opanda ndodo osungira makina oyendetsera kutsogolo okhala ndi kuyimitsidwa kodziyimira pawokha.

 

Zigawo ndi machitidwe a injini

 

Kusonkhanitsira ma sikelo a singano a zida zoyendetsera lamba, ma tensioner ndi ma jenereta mu injini ya thirakitala kumapitirira ma pulley, ma pump ndi ma fan bearing ndi ndodo zolumikizira.

 

Makina okolola

 

Mu ntchito zauinjiniya waulimi, pali zisindikizo kulikonse komwe kuli ma bearing ozungulira. Chisindikizo chabwino chili ndi ntchito ziwiri zofunika: kusunga mafuta abwino mkati mwa bearing ndikuletsa zodetsa ndi chinyezi kulowa mu bearing. Kutseka bwino kumawonjezera moyo wa bearing komanso kumawonjezera moyo wa makina aulimi.

 

Ma bearing a mpira wozungulira amagwiritsidwa ntchito makamaka pamakina okolola m'munda wa makina a ulimi, ndipo ma bearing a mpira wozungulira ndi nyumba zimakhala zosavuta kuyika ndipo zimatha kubweza kusakhazikika kwa shaft mkati mwa mtunda winawake.
