Ni iki gipimo cy'umutwaro udahinduka n'igipimo cy'umutwaro uhinduka w'ingufu?

 

Iyo tubajije ibyerekeyeikirangoicyitegererezo, dukunze kubona amahitamo abiri, Cr na Cor, Cr bivuga umutwaro uhindagurika w’ubwikorezi, Cor bivuga umutwaro uhoraho w’ubwikorezi. None se ni iki gipimo cy’umutwaro uhoraho n’igipimo cy’umutwaro uhoraho w’ubwikorezi? Ni iyihe sano n’itandukaniro biri hagati yabyo byombi?

Ibipimo bitatu by'ibanze bikunze gukoreshwa mu gushushanya imiyoboro yo kuzunguruka ni: umutwaro w'ibanze uhinduka Cr (radial) cyangwa Ca (axial) wujuje ibisabwa mu buzima runaka bwo kunanirwa; Imbaraga z'ibanze zihinduka Cor (radial) cyangwa Coa (axial) zujuje ibisabwa bimwe na bimwe by'imbaraga zihinduka hamwe n'umuvuduko wa nyuma No, ugenzura kwangirika kw'imiyoboro.

 

Ni ikiikirangoIgipimo cy'umutwaro udahinduka?

 

Igipimo cy'ibanze cy'umutwaro uhoraho w'ingufu zizunguruka (radial Cor, axial Coa) kivuga ku mutwaro wiyumvirwa wa radial cyangwa umutwaro uhoraho w'ingufu zo hagati uhwanye n'umutwaro ntarengwa w'ingufu iyo umutwaro runaka w'ingufu uterwa n'umutwaro runaka w'ingufu ku gice cyo hagati cy'ingufu zizunguruka n'umuhanda wo ku rubyiniro.

 

Ku byerekeye imiyoboro ya radial, umutwaro uhoraho ugenwa yerekeza ku mutwaro wa radial, ku byerekeye imiyoboro ya radial (ingular contact ball bearing) yerekeza ku gice cya radial cy'umutwaro ushyira umutwaro mu gice cy'impeta y'umutwaro, naho ku byerekeye imiyoboro ya traction, yerekeza ku mutwaro wo hagati.

 

Ni ukuvuga ko, igipimo cy'umutwaro uhoraho w'ibanze wa radial n'igipimo cy'umutwaro uhoraho w'ibanze wa axial by'ubwikorezi bivuga umutwaro ntarengwa ubwikorezi bushobora kwihanganira iyo buhagaze cyangwa buzunguruka.

 

Ubushobozi bwo gutwara imizigo bw'imizigo y'umupira w'igorofa ryimbitse mu gihe uhagaze cyangwa uzunguruka buhoro (umuvuduko n≤10r/min) ugaragazwa nk'umuzigo uhoraho.

 

Ni ikiikirangoIgipimo cy'umutwaro uhindagurika?

 

Igipimo cy'umutwaro uhindagurika w'ingufu bivuze: ubwikorezi buzunguruka bushobora kwihanganira umutwaro uhoraho wa radial (umutwaro uhoraho w'ingufu), munsi y'igikorwa cy'ubuzima bw'ibanze bwa 100W rpm, umutwaro uhoraho w'ingufu ugaragaza ubushobozi bw'ubwikorezi bwo kurwanya umunaniro uzunguruka. Igipimo cy'umutwaro uhindagurika w'ingufu za radial na thrust bearings kizwi kandi nka radial basic dynamic load rating na axial basic dynamic load rating, bigaragazwa na Cr na Ca.

 

Ubushobozi bwo gutwara imizigo bw'imigozi y'umupira mu gihe cyo kuzenguruka (umuvuduko n> 10r / mim) ni wo mutwaro w'ibanze upima imbaraga.

 

Kuki umutwaro uhinduka w'ingufu uruta umutwaro uhinduka uhinduka?

 

Umutwaro uhindagurika ugenwe yerekeza ku mutwaro uri ku gipimo cy'umuvuduko iyo ubuzima bwacyo ari miliyoni 1 ku muvuduko wa rpm. Umutwaro uhoraho ugenwe yerekeza ku guhuza hagati y'ikintu kizunguruka n'inzira y'urujya n'uruza ari byo biremereye cyane iyo icyuma kizunguruka kiri mu mwanya wacyo, kandi igiteranyo cy'ihindagurika rihoraho ry'ikintu kizunguruka n'inzira y'urujya n'uruza ni 1/10,000 cy'umurambararo w'ikintu kizunguruka.

 

Hari isano runaka hagati y'igihe cy'umurimo w'icyuma gifata ibiremereye n'umutwaro w'icyuma gifata ibiremereye, none se ni mu bihe ki duhitamo icyuma gifata ibiremereye dukurikije umutwaro w'icyuma gifata ibiremereye? Ingingo z'ingenzi ni izi zikurikira:

 

Icyitonderwa: Hari ubwo ingano y'ubwikorezi igomba guhitamo hakurikijwe igipimo cy'umutwaro udahinduka (cyasobanuwe nka Co kugira ngo byorohe gusobanura) aho guhitamo igihe cy'ubwikorezi.

 

1. Mu gihe cy'umutwaro uhoraho cyangwa uhoraho, icyuma gifata imizigo kiba gihagaze.

 

2. Munsi y'umutwaro, bearing ikora gusa verisiyo igenda buhoro cyangwa ihinduka.

 

3. Munsi y'umutwaro, umuvuduko wa bearing ni muto cyane (munsi ya revolutions 10 ku munota) kandi ukeneye igihe gito gusa. By'umwihariko, muri iki gihe, ku mutwaro uhwanye na P, igipimo cy'ibanze cy'umutwaro C gikenewe ni gito cyane hakurikijwe formula y'ubuzima, ku buryo bearing yatoranijwe ishobora kuremererwa cyane mu bikorwa.

 

4. Uretse umutwaro usanzwe wo gukora, igomba no kwihanganira umutwaro uremereye cyane, kandi icyuma gifata imizigo kirimo kuzenguruka.

 

Muri buri kimwe muri ibi bihe, umutwaro ushobora kwihanganira icyuma gitwara imizigo ntuterwa n'umunaniro w'ibikoresho, ahubwo uterwa n'uburyo inzira yo gusimbuka burundu iterwa n'umutwaro.
