Ibiranga ● Umupira wumupira uhuza umupira hamwe ninzira nyabagendwa yimpeta yimbere nimpeta yinyuma irashobora guhuza kumpande yerekeza kumurongo.Iyo ikoreshejwe wenyine, umutwaro wa axial ugarukira ku cyerekezo kimwe, kandi birakwiriye guhuza umutwaro wumutwaro wa axial hamwe nu mutwaro wa radiyo.● Kuberako ibyo bitwara bifite aho bihurira, imbaraga zingirakamaro zikorwa mugihe umutwaro wa radiyo ukora.Kubwibyo, muri rusange ikoreshwa muburyo bwo guhuza cyangwa guhuza kumpande zombi.● Hariho kandi ubwoko bukoresha imipira yubutaka.Inguni yo guhuza Hariho ubwoko bubiri bwo guhuza, 15 ° na 25 °.15 ° ikoreshwa mubikorwa byihuse.25 ° irakwiriye mugihe aho bikenewe gukomera.Akazu kakozwe muri polyamide nkibisanzwe.Nyamuneka koresha akazu ka polyamide munsi ya 120 °.Ibipimo bifatika kandi bizenguruka bihuye na JIS icyiciro cya 5 cyangwa 4. Nyamuneka reba urupapuro rwa 7. Preload ● Shiraho ubwoko 4 bwamafaranga asanzwe.Hitamo preload yifuza ukurikije ibipimo byo guhitamo kumeza iburyo.Reba ku rupapuro rwa 16 kugeza ku cya 18 ku mubare usanzwe wa preload kuri buri cyiciro n'ubunini.

Guteranya Kugirango ukoreshe inteko yinkingi nyinshi, nyamuneka reba urupapuro rwa 12 kugeza 13. Ubwoko bwumupira wumubumbyi Kugirango ugabanye imbaraga za centrifugal yumupira mugihe cyo kuzunguruka byihuse, umupira wubutaka ufite ubucucike buke ugereranije no gutwara ibyuma.● Reba imbonerahamwe ikurikira kumiterere itandukanye yububumbyi hamwe nicyuma.● Ongeraho “SH6-” mu ntangiriro yumubare wikitegererezo wifashishije imipira yubutaka.● Imbere ya preload hamwe na axial gukomera bikubye inshuro 1,2 yubwoko bwumupira wicyuma.Imbere yikimenyetso cyo gutoranya ibipimo E (micro preload) Irinde kunyeganyega kwa mashini no kunoza ukuri L (preload yoroheje) Umuvuduko mwinshi (dmn agaciro ka 500.000) uracyafite gukomera M (preload yo hagati) Igisekuru cyoroshye kurenza umuvuduko usanzwe Rigidity H hamwe na hejuru preload (preload iremereye) itanga ubukana ntarengwa kumuvuduko muke.
