Makhalidwe otengera mpira

Mipira ya thrust ndi zigawo zofunika pazida zosiyanasiyana zamakina ndipo zimagwira ntchito yofunika kwambiri pothandizira katundu wa axial. Ma fani awa amapangidwa kuti athe kupirira mphamvu za axial m'njira zinazake ndipo amagawidwa molingana ndi momwe angagwirire. Kutengera momwe mphamvu zimakhalira, ma bearing a mpira amatha kugawidwa m'njira imodzi komanso njira ziwiri.

Njira imodzi yolumikizira mpira imatha kupirira mbali imodzi ya axial ndikupereka bata ndi kuthandizira mbali imodzi. Kumbali inayi, ma berections a mpira wa Bidirectional thrust, amapangidwa kuti athe kupirira ma axial axial, omwe amapereka chithandizo mbali zonse ziwiri. Mphete ya shaft ya njira ziwiri zolumikizira mpira imagwirizana ndi shaft kuti zitsimikizire kulumikizana kotetezeka komanso koyenera, pomwe pamwamba pa mphete yapampando imakhala yozungulira. Kukonzekera kumeneku kumapereka ntchito yodzigwirizanitsa, kuchepetsa zotsatira za zolakwika za kukhazikitsa ndi kupititsa patsogolo ntchito yonse ya kubereka.

Chimodzi mwazofunikira za mayendedwe a mpira ndikumatha kunyamula katundu wa axial, koma osati ma radial. Kukhazikika kumeneku kumawapangitsa kukhala abwino kwa ntchito zomwe mphamvu za axial ndizovuta kwambiri, monga ma transmissions amagalimoto, makina owongolera ndi makina opanga mafakitale. Kuonjezera apo, mayendedwe a mpira wa thrust ali ndi liwiro lotsika kwambiri, lomwe ndilofunika kwambiri pamagwiritsidwe ntchito komwe kuwongolera ndi kukhazikika ndikofunikira.

Kapangidwe ndi kamangidwe ka thrustball bearings kumabweretsa mawonekedwe awo apadera komanso magwiridwe antchito. Ma bere awa nthawi zambiri amakhala ndi ma washer awiri okhala ndi mikwingwirima (shaft ndi mtundu) ndi seti ya mayendedwe a mpira pakati pawo. Msewu wothamanga wapangidwa kuti ulimbikitse kuyenda kosalala kwa mpira, potero kumatumiza mphamvu za axial.

Pankhani ya kapangidwe kazinthu, mayendedwe a mpira wa thrust nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri, chomwe chimapereka kulimba komanso mphamvu zolimbana ndi zovuta za ntchito za axial load. Kugwiritsiridwa ntchito kwa zipangizo zapamwamba kumatsimikizira kuti ma berewa amasungabe ntchito zawo pansi pa zovuta, motero zimathandizira kudalirika kwa makina kapena zipangizo zomwe zimayikidwa.

Kuphatikiza apo, mayendedwe a mpira wa thrust adapangidwa kuti aphatikize zinthu zomwe zimawonjezera magwiridwe antchito ndi magwiridwe antchito. Kukwera kwa mphete yapampando kumapangitsa kuti munthu adziyendetse bwino, zomwe zimakhala zopindulitsa kwambiri pamapulogalamu omwe pangakhale zolakwika pang'ono kapena kuyika. Kuthekera kodzigwirizanitsa kumeneku kumachepetsa zotsatira za kusalongosoka, kumathandizira kukulitsa moyo wobereka komanso kuchita bwino.

Chinthu chinanso chofunika kwambiri cha ma bearing a mpira ndi mphamvu zawo zonyamula katundu. Unidirectional thrust ball bearings amapangidwa makamaka kuti azitha kunyamula katundu wa axial mbali imodzi, kupereka kukhazikika ndi kuthandizira pamagwiritsidwe ntchito omwe mphamvu za unidirectional ndizofala. Mbali inayi, ma bearing a mpira a Bidirectional thrust, amapangidwa kuti azinyamula katundu wa axial mbali zonse ziwiri, kupereka kusinthasintha komanso kudalirika pakugwiritsa ntchito ndi mbali zosiyanasiyana zamphamvu.

Kuchita kwa mayendedwe a mpira wothamanga kumakhudzidwanso ndi liwiro la malire, lomwe limatanthawuza kuthamanga kwambiri komwe kunyamula kumatha kugwira ntchito moyenera komanso motetezeka. Kuthamanga kwa malire otsika kwa mayendedwe a mpira kumawapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kuwongolera komanso kukhazikika kuti zitsimikizire kukhazikika ndi kudalirika kwa makina kapena zida.

Mwachidule, mayendedwe a mpira ndi zinthu zofunika kwambiri pamakina osiyanasiyana, zomwe zimapereka chithandizo chofunikira pamakina a axial mbali zina. Makhalidwe awo apadera, kuphatikizapo kupirira katundu wa axial, katundu wodzipangira okha ndi liwiro lotsika kwambiri, amawapangitsa kukhala oyenerera ntchito zomwe mphamvu za axial zimakhala zazikulu. Mapangidwe, kapangidwe kazinthu ndi mawonekedwe a mayendedwe a mpira amathandizira kudalirika kwawo komanso kuchita bwino, kuwapangitsa kukhala ofunikira kwambiri pamafakitale osiyanasiyana ndi magalimoto.
