Imipira yo guhuza umupira ifite umurongo umwe n'imirongo ibiri

Ibyuma by'umupira w'angolizigizwe n'impeta y'inyuma, impeta y'imbere, umupira w'icyuma, n'akazu. Zishobora gutwara imizigo yombi ya radial na axial, kandi zishobora no gutwara imizigo ya axial, kandi zishobora gukora neza ku muvuduko wo hejuru. Ibyuma by'umupira bya angular contact bearings bishobora kwihanganira imizigo ya axial mu cyerekezo kimwe gusa. Iyo ubwo bwoko bw'impeta bufite imizigo ya radial, kubera ko umurongo w'umutwaro w'ibintu bizunguruka n'umurongo w'umutwaro wa radial bitari mu murongo umwe wa radial, igice cy'imbere cya axial kirakorwa, bityo kigomba gushyirwamo bibiri bibiri.

 

1. Imipira yo guhuza umupira ifite umurongo umwe

Ibyuma by'umupira w'inguni bifite umurongo umwe bifite imiterere ikurikira:

(1) Ibyuma by'umupira w'inguni bishobora gutandukanywa

Uruhande rw'inyuma rw'ubu bwoko bw'ubwirinzi nta mwanya wo gufunga ufite, ushobora gutandukanywa n'impeta y'imbere, ikiraro n'aho umupira uhurira, kugira ngo ubashe gushyirwa ukwawo. Ubu bwoko bw'ubwirinzi buto bufite umurambararo w'imbere uri munsi ya mm 10 bukoreshwa cyane mu byuma bihindura imiterere y'umubiri, moteri nto n'ibindi bikoresho bifite ibisabwa byinshi kugira ngo habeho kuringaniza imikorere y'umubiri, urusaku, guhinda no kudahungabana.

 

(2) Ibyuma bito bishobora gutandukanywa by'umupira w'inguni

Umuyoboro w'impeta w'ubu bwoko bw'impeta ufite umwobo wo gufunga, bityo impeta zombi ntizishobora gutandukana. Hariho ubwoko butatu hakurikijwe inguni yo guhuza:

(1) Inguni yo gukomatanya α = 40°, ikwiriye gutwara umutwaro munini wo mu ruhande;

(2) Inguni yo guhuza α = 25°, ikoreshwa cyane cyane mu gukoresha neza ibyuma bifunga;

(3) Inguni yo guhuza α = 15°, ikoreshwa cyane cyane ku mabereti manini atunganye.

(3) Ibyuma by'umupira w'amakona bitondetse mu buryo bubiri

 

Ibyuma by'umupira w'angoliIbice bibiri bitondetse bikoreshwa mu kwakira imizigo yombi ya radial na axial, ndetse n'imizigo ya radial n'imizigo ya axial mu cyerekezo icyo ari cyo cyose. Ubwo bwoko bw'ubwikorezi butoranywa kandi bugahuzwa n'uwabukoze hakurikijwe ibisabwa mbere yo gupakira, kandi bugahabwa ababukoresha. Iyo ubwikorezi bushyizwe ku mashini kandi bugakomezwa, umwanya uri muri bearing urakurwaho burundu, maze impeta n'umupira biba biri mu rwego rwo gupakira, bityo bikanoza ubukana bw'ubwikorezi bufatanye.

 

Imipira yo guhuza umupira w'angoli itondekanye mu maguru yombi iboneka mu buryo butatu butandukanye:

(1) Imiterere y'inyuma, post-code DB, iyi miterere ifite uburinzi bwiza, imikorere myiza yo kwihanganira igihe cyo guhindagura, kandi bearing ishobora kwihanganira umutwaro w'impande zombi;

 

(2) Imiterere y'imbonankubone, kode y'inyuma ni DF, ubukana bw'iyi miterere n'ubushobozi bwo kwihanganira igihe cyo guhinduka ntabwo ari byiza nk'imiterere ya DB, kandi icyuma gishobora kwihanganira umutwaro w'inzira ebyiri;

 

(3) Imiterere ya Tandem, post-code DT, iyi miterere ishobora kandi guhuzwa mu buryo bukurikiranye hamwe n'imiyoboro itatu cyangwa irenga ku nkunga imwe, ariko ishobora gutwara umutwaro w'imiyoboro mu cyerekezo kimwe gusa. Ubusanzwe, kugira ngo habeho kuringaniza no kugabanya kwimuka k'umugozi, icyuma gishobora gutwara umutwaro w'imiyoboro mu cyerekezo kindi gishyirwaho ku nkunga yindi.

 

2. Imipira yo guhuza impande ebyiri

Imigozi y'umupira w'inguni ifite umurongo ubiri irangwa n'ubushobozi bwo kwihanganira umutwaro w'imizigo ya radial n'imizigo ya axial icyarimwe, bigabanyiriza inzira impande zombi z'umugozi.

Ugereranyije n'uburyo bwo gukurura umupira w'impande ebyiri, ubwo bwoko bw'uburyo bufite umuvuduko mwinshi, inguni yo gukoraho ya 32°, gukomera neza, kandi bushobora kwihanganira igihe kinini cyo guhindagura, kandi bukoreshwa cyane mu gice cy'imbere cy'imodoka (hari ubwoko bumwe bukoresha ibyuma binini bifite umurongo ubiri bingana).

 

Hari ubwoko bune bw'imiterere y'imigozi y'umupira w'inguni ifite umurongo ubiri:

(1) Igishushanyo mbonera gisanzwe cya bearing zo mu bwoko bwa A zifite umurambararo wo hanze uri munsi ya mm 90 cyangwa ungana na zo. Nta notch y'umupira ihari, bityo ishobora kwihanganira imitwaro ingana y'umurongo mu byerekezo byombi. Akazu koroheje k'ibirahure gashyigikiwe na nylon 66 karakoreshwa, kandi izamuka ry'ubushyuhe bw'ibearing ni rito cyane.

(2) Igishushanyo mbonera gisanzwe cya bearing zo mu bwoko bwa A zifite umurambararo wo hanze urenze mm 90. Hari agace ko gupakira ku ruhande rumwe kandi gafite akazu k'icyuma gafite ikimenyetso cyangwa akazu gakomeye k'umuringa.

(3) Ubwoko bwa E ni imiterere ikomeye, ifite agace k'umupira ku ruhande rumwe, gashobora gufata imipira myinshi y'icyuma, bityo ubushobozi bwo gutwara ibintu bukaba buri hejuru.

 

(4) Ibyuma by'imipira bifite umurongo ibiri bifite umupfundikizo w'umukungugu ku mpande zombi n'igishushanyo cy'impeta yo gufunga ubwoko bwa A n'ubwoko bwa E bishobora gushyirwaho umupfundikizo w'umukungugu (ubwoko butajyanye n'umukungugu) cyangwa impeta yo gufunga (ubwoko bw'umukungugu) ku mpande zombi. Imbere muri ibyo byuma by'imipira byuzuyemo amavuta ya lithium arwanya ingese, kandi ubushyuhe bwo gukora muri rusange ni -30 ~ + 110 ° C. Nta kongera gusigwa amavuta bikenerwa mu gihe cyo kuyikoresha, kandi ntibigomba gushyushwa cyangwa gusukurwa mbere yo kuyishyiraho.

 

Mu gushyiramo imigozi y’umupira w’inguni ifite umurongo ubiri, ugomba kwitonda ko nubwo imigozi ishobora kwihanganira imitwaro y’umurongo ugana ku ruhande rumwe, niba hari agace k’umupira ku ruhande rumwe, ugomba kwitonda kugira ngo umutwaro w’umurongo mukuru udahita mu mwobo uri ku ruhande rucitsemo uduce.
