Nigute ushobora guhitamo igipimo cyo guhimba?

Mugihe igipimo cyo guhimba cyiyongera, imyenge yimbere iragabanuka kandi de-dendrite ya-cast iravunika, bikavamo iterambere ryinshi mumiterere ya maremare maremare kandi ahindagurika. Ariko iyo igipimo cyo kurambura igice kinini kirenze 3-4, mugihe igipimo cyigice cyo guhimba cyiyongera, imiterere ya fibre igaragara irashirwaho, bigatuma igabanuka rikabije ryibipimo bya plastike yimiterere yimashini ihinduranya, biganisha kuri anisotropy yibihimbano. Niba igipimo cyo guhimba ari gito cyane, guhimba ntibishobora kuzuza ibisabwa. Niba ari nini cyane, byongera akazi ko gukora kandi bigatera anisotropy. Kubwibyo, guhitamo igipimo cyo guhimba cyumvikana nikibazo cyingenzi, kandi ikibazo cyo guhindagurika kuringaniza mugihe cyo guhimba nacyo kigomba gusuzumwa.

Ikigereranyo cyo guhimba gikunze gupimwa nurwego rwo guhindura ibintu mugihe kirekire. Yerekeza ku kigereranyo cy'uburebure na diametre y'ibikoresho bigomba gukorwa, cyangwa igipimo cy'ahantu hambukiranya igice cy'ibikoresho fatizo (cyangwa fagitire yabanjirije) mbere yo guhimba ahantu hambukiranya ibicuruzwa byarangiye nyuma yo guhimba. Ingano yikigereranyo cyo guhimba igira ingaruka kumiterere yibyuma hamwe nubwiza bwo kwibagirwa. Kongera igipimo cyo guhimba ni ingirakamaro mugutezimbere microstructure hamwe nimiterere yibyuma, ariko ibipimo byo guhimba bikabije nabyo ntabwo ari ingirakamaro.

Ihame ryo guhitamo ibipimo byo guhimba ni uguhitamo bito bishoboka mugihe wizeye ibisabwa bitandukanye kubibagirwa. Umubare wo guhimba usanzwe ugenwa ukurikije ibihe bikurikira:

1. Iyo ibyuma byujuje ubuziranenge bwa karubone hamwe nibyuma byubatswe byubatswe ku buntu ku nyundo: kubibagirwa ubwoko bwa shaft, bihimbwa biturutse ku byuma, kandi igipimo cyo guhimba kibarwa hashingiwe ku gice nyamukuru kigomba kuba ≥ 3; Ikigereranyo cyo guhimba kibarwa hashingiwe kuri flanges cyangwa ibindi bice bisohoka bigomba kuba 75 1.75; Iyo ukoresheje fagitire y'ibyuma cyangwa ibikoresho bizunguruka, igipimo cyo guhimba kibarwa ukurikije igice nyamukuru ni ≥ 1.5; Ikigereranyo cyo guhimba kibarwa ukurikije flanges cyangwa ibindi bice bisohoka bigomba kuba ≥ 1.3. Kubibagirwa impeta, igipimo cyo guhimba kigomba kuba ≥ 3. Kubibagirwa disiki, bahimbwe biturutse ku byuma, hamwe n’ikigereranyo cyo guhimba kibabaje cya ≥ 3; Mu bindi bihe, igipimo cyo guhimba kibabaje kigomba kuba> 3, ariko inzira yanyuma igomba kuba>.

2.Imyenda mvaruganda yimyenda ya billet ntigomba gukuraho gusa inenge zayo, ahubwo igomba no gukwirakwiza karbide imwe, bityo hagomba gukoreshwa igipimo kinini cyo guhimba. Ikigereranyo cyo guhimba ibyuma bitagira umwanda birashobora gutoranywa nka 4-6, mugihe igipimo cyo guhimba ibyuma byihuta bigomba kuba 5-12.
