Kodi kutsamira kwa zimbalangondo ndi chiyani komanso ntchito ya kutsamira kwa zimbalangondo

 

Kukonza ma chamfering ndi mawu omwe amagwiritsidwa ntchito mu uinjiniya wamakina kuchotsa ma burrs omwe amayambitsidwa ndi makina pazigawo ndikuthandizira kusonkhanitsa ziwalo. Ma chamferi amatha kuwoneka kulikonse m'miyoyo yathu, pamafelemu a mafoni am'manja, pazitseko zotenthetsera, pa miphika, ndi zina zotero.

 

Kawirikawiri, ntchito ya chamfering ndi kuchotsa ma burrs ndikuwapanga kukhala okongola. Komabe, pa chamfer yomwe yatchulidwa mwachindunji muzojambula, nthawi zambiri ndi chofunikira pa njira yoyikira, monga chitsogozo choyikira chachogwirira,ndipo ma arc chamfer ena (kapena otchedwa arc transitions) angathandizenso kuchepetsa kupsinjika ndi kulimbitsa mphamvu ya zigawo za shaft. Kuphatikiza apo, zingathandizenso kusonkhana mosavuta, komwe nthawi zambiri kumachitika ntchito isanathe.

 

Pazigawo za makina a zaulimi, makamaka kumapeto kwa zolumikizira zozungulira ndi mabowo ozungulira nthawi zambiri zimakonzedwa kukhala ma chamfers pafupifupi 45°Ma chamfer awa ali ndi ntchito zosiyanasiyana, pokonza zinthu ayenera kuyang'aniridwa mosamala, ndikugwiritsa ntchito mokwanira, apo ayi zimabweretsa mavuto ambiri pakukonza makina a ulimi, komanso kulephera kosayembekezereka. Mwachitsanzo, njira yopangira zinthu zazing'ono monga mabolts isanayambe, chamfer imachitidwanso kuti zinthuzo zilowe mu nkhungu.

 

Kodi chogwirira cha bearing chamfer chimachita chiyani

 

1. Chitsulo cholumikizira chiyenera kukhala ndi chamfering panthawi yokonza zinthu mopanda mphamvu chisanayambe kutenthedwa, kotero kuti chimagwira ntchito yofunika kwambiri pa kutentha kwa zinthuzo, kutulutsa kupsinjika, kugawanso kapangidwe ka mkati, kusowa kwa ming'alu, komanso kuchepetsa kusintha kwa zinthu. Chamfering imatha kuthetsa vuto la kuchuluka kwa kupsinjika.

 

2. Chamfer ndi deburr, kuti chinthucho chisakhale chakuthwa ndipo sichidzadula wogwiritsa ntchito

 

3. Imagwira ntchito yotsogolera ndi kuyika zinthu pamalo ake panthawi yosonkhanitsa.

 

Kawirikawiri, chamfer yakunja ya mphete yakunja ndi chamfer yamkati ya mphete yamkati ya bearing ndi yozungulira, kuwonjezera pa kupewa kupsinjika kwa kukhudzana, chinthu chofunikira kwambiri ndikupangitsa kuti kuyika kukhale kosavuta. Makona ozungulira amalola kuti katundu aziyenda bwino.

 

Makamaka pa ndondomeko yoyendetsera, malo oimikapo shaft ndi shaft bowo lofanana, kutanthauza, phewa la shaft ndi gawo lolumikizira mpando woyendetsera, kukula kwa chamfer kwa gawoli kumakhudza mwachindunji ngati bere lingayikidwe bwino pamalo pake.

 

Bearing imayikidwa pakati pa bokosi la axle ndi shaft, ndipo ngodya yake ya chamfer ndi yayikulu kuposa ya bokosi la bearing ndi phewa la shaft, ndipo chamfer ya bearing iyenera kukhala yayikulu kuposa arc iyi kuti zitsimikizire kuti bearing ikugwirizana ndi malo oimikapo a axial.

 

PamenechogwiriraChamfer ndi yochepa kuposa bokosi lonyamula katundu ndipo chamfer ya phewa, singathe kuyikidwa pamalo ake, zomwe zimapangitsa kuti pakhale mavuto ambiri monga kupsinjika maganizo pa chamfer yonyamula katundu, kupendekera kwa msonkhano, ndi ziwalo zina zofanana sizingagwirizane.
