Imikorere ya Bear
Ikiraro cyikiraro gikoreshwa mu kwimura imbaraga ziva mubikorwa byububiko, bikemerera ubwoko bukurikira bwimiterere yimiterere: Ibikorwa byubuhinduzi;ni ugusimbuka mubyerekezo bihagaritse kandi bitambitse bitewe nindege cyangwa imbaraga zindege-nkumuyaga nuburemere.Kuzenguruka;impamvu kubera ibihe.Kugeza hagati y'iki kinyejana, imiyoboro yakoreshejwe yari igizwe n'ubwoko bukurikira:
· Pin
Uruhare
· Rocker
· Ibyuma byo kunyerera
Igikoresho cya pin ni ubwoko bwimyenda ihamye yakira kuzenguruka hakoreshejwe ibyuma.Kwimura mubisobanuro ntabwo byemewe.Ipine iri hejuru igizwe hejuru no hepfo igice cyizengurutswe hejuru hamwe na pin ikomeye izenguruka yashyizwe hagati.Mubisanzwe, hariho imipira kumpande zombi za pin kugirango pin itanyerera ku ntebe no kurwanya imitwaro yo hejuru niba bikenewe.Isahani yo hejuru ihujwe nisahani yonyine muguhindura cyangwa gusudira.Isahani yo hepfo yagoramye yicaye ku isahani yububiko.Kuzenguruka biremewe.Kwimuka kuruhande no guhinduranya birabujijwe.
Ubwoko bwa Roller
Kubikorwa byo kwigunga mubikoresho byo kwigunga, roller hamwe no gutwara umupira birakoreshwa.Harimo umuzingo wa silindrike n'imipira.Birahagije kurwanya ibikorwa bya serivise no kugabanuka bitewe nibikoresho byakoreshejwe.
AASHTO isaba ko umuzingo wo kwagura wagira “utubari twinshi two ku ruhande” kandi ukayoborwa n’ibikoresho cyangwa ubundi buryo bwo gukumira urujya n'uruza, kunyerera, no kunyerera (AASHTO 10.29.3).
Ingaruka rusange kuri ubu bwoko bwo gutwara ni uburyo bwo kwegeranya ivumbi n imyanda.Urugendo rurerure ruremewe.Kwimuka kuruhande no kuzunguruka birabujijwe.
Ubwoko bwa Rocker
Igikoresho cya rocker ni ubwoko bwo kwaguka buza muburyo butandukanye.Mubisanzwe bigizwe na pin hejuru yorohereza kuzunguruka, hamwe nubuso bugoramye hepfo yakira ingendo zo guhindura.Ibikoresho bya rocker na pin bikoreshwa cyane cyane mubiraro byibyuma.
Ibikoresho byo kunyerera
Igikoresho cyo kunyerera gikoresha icyuma kimwe cy'indege icyuma kinyerera ku kindi kugira ngo gihuze ibisobanuro.Kunyerera kunyerera bitanga imbaraga zo guteranya zikoreshwa muburyo bwimiterere, imiterere, hamwe nubwikorezi ubwabwo.Kugabanya izo mbaraga zo guterana, PTFE (polytetrafluoroethylene) ikoreshwa nkibikoresho byo kunyerera.PTFE rimwe na rimwe yitwa Teflon, yitiriwe ikirango gikoreshwa cyane na PTFE.Ibikoresho byo kunyerera bikoreshwa byonyine cyangwa bikunze gukoreshwa nkibigize ubundi bwoko bwimyitozo.Kwiyegereza neza birashobora gukoreshwa gusa mugihe kuzunguruka guterwa no gutandukana kumfashanyo ari ntagaciro.Baragarukira rero ku burebure bwa metero 15 cyangwa munsi ya ASHTTO [10.29.1.1]
Sisitemu yo kunyerera hamwe na coefficente yagenwe mbere yo guterana irashobora gutanga akato mugabanya umuvuduko nimbaraga zimurwa.Abanyerera barashobora gutanga imbaraga zo guhangana na serivise, guhinduka no guhatira imbaraga-kunyerera.Ibishushanyo cyangwa shitingi bikunze gukundwa kuruta sisitemu yo kunyerera kubera ingaruka zo kugarura.Flat slide ntabwo itanga imbaraga zo kugarura kandi haribishoboka byo kwimurwa hamwe na nyuma yimitingito.
Knuckle Pinned Bearing
Nuburyo bwihariye bwa Roller Bearing aho pin ya Knuckle itangwa kugirango byoroshye kunyeganyega.Ipine ya knuckle yinjizwa hagati yo hejuru no hepfo.Hejuru ya casting yometse kuri Bridge superstructure, mugihe gukina hasi bishingiye kumurongo wuruziga.Imashini ya pinuckle irashobora kwakira ingendo nini kandi irashobora kwakira kunyerera kimwe no kuzunguruka
Amabati
GUKORA INKOKO bigizwe na silindiri ntoya, cyangwa inkono, kumurongo uhagaritse hamwe na disiki ya neoprene yoroheje gato kuruta silinderi kandi yashyizwe imbere imbere.Piston yicyuma ihuye na silinderi kandi ifite kuri neoprene.Impeta z'umuringa ziringaniye zikoreshwa mu gufunga reberi hagati ya piston n'inkono.Rubber yitwara nkamazi ya viscous itemba nkuko kuzunguruka bishobora kubaho.Kubera ko ubwikorezi butazarwanya ibihe byo kunama, bigomba guhabwa intebe iringaniye.
Ibikoresho bya Elastomeric byo mu kibaya (Reba PPT)
Amashanyarazi ya Elastomeric
Imyenda igizwe nibice bitambitse bya sintetike cyangwa reberi karemano mubice bito bifatanye hagati yicyuma.Iyimikorere irashobora gushyigikira imitwaro ihanamye iremereye hamwe na deformations nto cyane.Ibi byuma byoroshye guhinduka munsi yimizigo.Isahani y'ibyuma irinda reberi guturika.Amashanyarazi ayobora atangwa kugirango yongere ubushobozi bwo kugabanuka nkuko bisanzwe bya elastomeric bidatanga damping ikomeye.Mubisanzwe byoroshye muburyo butambitse kandi bigoye mubyerekezo bihagaritse.
Igizwe na elastomeric yamashanyarazi ifite ibikoresho bya silinderi yo hagati.Igikorwa cya reberi-ibyuma byometseho igice cyo gutwara ni ugutwara uburemere bwimiterere no gutanga ibyoroshye nyuma yumusaruro.Intangiriro yibanze yashizweho kugirango ihindure plastike, bityo itange imbaraga zo kugabanuka.Ibikoresho byo mu bwoko bwa reberi bikoreshwa mu bice bikoresha imitingito kubera imikorere yabyo munsi y’umutingito.
