Ni irihe tandukaniro riri hagati y'udupira tw'imizingo duto (cylindrical roller bearing) n'udupira tw'imizingo duto (needle roller bearing)?

 

Ibyuma bizunguruka by'uruziga

Ibyuma bizunguruka by'uruzigani iz'ubwikorezi bw'ubuziranenge, kandi ubuyobozi bw'impande z'ubwikorezi bw'inyuma bw'inyuma bugizwe n'akazu, imigozi n'impeta y'umugozi w'ubuyobozi, bishobora gutandukanywa n'indi mpeta y'ubwikorezi kandi bikaba iby'ubwikorezi bushobora gutandukana. Ubwo bwoko bw'ubwikorezi bworoshye gushyiramo no gusenya, cyane cyane iyo impeta z'imbere n'inyuma, imigozi n'aho bifungira bikenewe kugira ngo bihuze n'ingaruka mbi.

 

Izi bearing zikorana ku murongo n'inzira zo gusiganwa. Ubushobozi bwo gutwara ni bunini, kandi ahanini zitwara imizigo ya radial. Ibearing imwe gusa ifite flanges mu mpeta z'imbere n'inyuma zishobora gutwara umutwaro muto uhoraho cyangwa umutwaro munini uhoraho; Ugereranyije n'izindi bearing zikusanya zifite ingano imwe, ubu bwoko bw'ubwikorezi bufite imiterere y'umutwaro mwinshi, urusaku rwo hasi n'umuvuduko mwinshi, kandi uburyaryate hagati y'ikintu gizunguruka n'impeta y'impeta ni buto, kandi bukwiriye kuzunguruka vuba cyane. Ni bwiza gukoreshwa n'ubwoko bwose bw'imashini zitunganya neza n'imashini zicukura imigozi. Ariko, imigozi, ibintu bizunguruka n'ibindi bice bifitanye isano bihuye n'izo bearing bigomba gutegurwa neza.

 

Dukurikije niba impeta ifite flange cyangwa idafite, ishobora kugabanywamo NU, NJ, NUP, N, NF n'izindi berearingi z'imirongo imwe, na NNU, NN n'izindi berearingi z'imirongo ibiri. Imbere ni imiterere ishobora gutandukanywa ifite impeta y'imbere n'inyuma.

 

Ibyuma bizunguruka by'uruzigaUtuzu duto tudafite uduce duto mu mpeta z'imbere cyangwa iz'inyuma dushobora kwimurwa mu buryo bw'umurongo kandi dushobora gukoreshwa nk'uduce tw'inyuma. Utuzu duto tw'inyuma dufite uduce tubiri ku ruhande rumwe rw'impeta z'imbere n'iz'inyuma hamwe n'agace kamwe ku rundi ruhande rw'umuyoboro w'impeta bishobora kwihanganira uburemere runaka bw'umurongo mu cyerekezo kimwe. Muri rusange, hakoreshwa utuzu duto two gusigaho icyuma, cyangwa utuzu duto tw'umuringa twahinduwemo uduce dukomeye. Ariko, hari utuzu duto dukorwa hakoreshejwe polyamide.

 

Ibyuma bifunguye bifite urushinge rw'ingufu

 

Ibyuma bizunguruka by'urushinge

Ibyuma bizunguruka by'inshinge ni ibyuma bizunguruka bifite imigozi y'ubugari, byombi bikaba bito kandi birebire ugereranyije n'umurambararo wabyo. Ibyuma nk'ibyo byitwa imigozi y'inshinge. Nubwo bifite ibice bito, ibyuma bizunguruka bifite ubushobozi bwo gutwara imizigo myinshi, kandi ibyuma bizunguruka by'inshinge bifite imigozi mito n'indende (umurambararo wa miringi D).≤5mm, L/D≥2.5, L ni uburebure bwa roller), bityo imiterere ya radial ni nto, kandi uburebure bwazo bw'imbere n'ubushobozi bwo gutwara ni bimwe n'ubw'ubundi bwoko bwa bearing, hamwe n'uburebure buto bw'inyuma, bukwiriye cyane cyane inyubako zishyigikira zifite ingano ntoya zo gushyiraho radial.

 

Kubwibyo, imigozi y'urushundura ikoreshwa cyane cyane mu bihe bito, bityo ikoreshwa cyane mu modoka, moto, n'imashini zikora imyenda. Kandi impeta y'imbere y'urushundura ni amahitamo, mu magambo make, niba ubukana n'ubukana bw'urushundura byujuje ibisabwa, ntushobora guhuza impeta y'imbere (umwanya ni muto), ariko niba urwego rw'imikorere y'urushundura ari ruto, cyangwa rworoshye cyane, ugomba guhuza impeta y'imbere nk'inzira yo gusiganwa.

 

Itandukaniro riri hagati yaimiringa y'imiringa izunguruka n'imiringa y'imiringa izungurukani ibi bikurikira:

 

1. Igice cyo kuzingira cy'umuzingo w'uruziga ni umuzingo utose; Igice cyo kuzingira cy'umuzingo w'uruziga ni imizingo ifite ishusho nk'iy'urushinge;

 

2. Imiterere y'udupira tw'imizingo duto duto ni minini kurusha imiterere y'udupira tw'imizingo duto;

 

3. Uretse imbaraga za radial, uruziga ruzunguruka rushobora kwihanganira imbaraga za axial, mu gihe uruziga ruzunguruka rufite imbaraga za radial gusa;

 

4. Imirongo izunguruka ya Cylindrical igabanyijemo imirongo imwe, imirongo ibiri n'imirongo myinshi, ikoreshwa mu bidukikije n'ibihe bitandukanye;

 

5. Umuvuduko w'imikorere y'udupira tw'imizingo duto (cylindrical roller bearing) uri hejuru y'uwo udupira tw'imizingo duto duto dukoreshwa mu gukora;

 

6. Imigozi yo kuzunguruka ikozwe mu cylindrical muri rusange ikozwe mu cyuma cyo hejuru gifite ubwiza n'icyuma cyihariye; Imigozi yo kuzunguruka ifite inkuta nto iterwa n'ibyuma byabugenewe irangijwe mu byuma. 

 

Igihe cyo kuyikoresha

 

Mu miterere ya mekanike, ingano y'umugozi muri rusange ibanza kugenwa, hanyuma umugozi uzunguruka ugatoranywa hakurikijwe ingano y'umugozi. Ariko, iyo umugozi ugabanijwe mu cyerekezo cy'umurambararo w'imashini, hatoranywa imigozi y'urumuri rw'inshinge, imigozi y'umupira cyangwa imigozi y'urumuri rwinshi n'urumuri rwinshi; Iyo aho umugozi uri muri iyo mashini uhagaze, haboneka imigozi y'umupira cyangwa imigozi y'urumuri ifunganye cyangwa ifunganye cyane.

 

Ibice by'umugozi w'urushinge n'ibice by'akazu, ibyuma by'urushinge by'inyuma by'urushinge byashyizweho ikimenyetso, ibyuma by'urushinge by'urushinge bikomeye, ibyuma by'urushinge by'urushinge bikoreshwa cyane muri sisitemu yo kohereza ubutumwa, sisitemu yo kuyobora, moteri ya moto ihuza moteri y'imodoka n'imashini z'ubwubatsi, nibindi, kandi bikwiranye n'ibihe bifite umwanya muto n'ubushobozi bunini bwo gutwara. ibyuma by'urushinge bifite ibyuma bito kandi birebire (uburebure bw'urushinge ni inshuro 3 ~ 10 z'umurambararo, kandi umurambararo muri rusange nturenze 5mm), bityo imiterere y'urushinge ni nto, kandi ingano y'umurambararo w'imbere n'ubushobozi bwo gutwara ni bimwe n'ubw'ubundi bwoko bw'ibyuma, kandi umurambararo w'inyuma ni muto cyane, ibi bikaba bikwiriye cyane ku bisubizo by'inkunga aho ingano y'urushinge rw'urushinge ari nke.
