1. Kahor inta aan la adkeynin isku xirka dunta ka hor inta aan la qaadin culeyska shaqada, furaha waxaa lagu dhejiyaa ficilka xoogga hore ee adkeynta.
1. Ujeedada ka hor adkeynta
1) Kordhi adkaanta xidhiidhka
2) Kordhi cidhiidhiga
3) Hagaajinta awoodda dabacsanaanta
Go'aaminta rarka hore ee hadhaaga:1) Wax isbeddel ah kuma iman culayska shaqada:FR FR= (0.2 ~ 0.6)2) Culayska shaqadu wuu is beddelaa:FR= (0.6~1) F3) Waxa jira shuruudo cidhiidhi ah:Fp FR=(1.5~1.8)
$10-7 Agabka iyo culaysyada la ogolyahay ee boolal1.Bolt materialBolts waxa loo kala saaray si waafaqsan sifada farsamaysan, heerka qarankuna wuxu dhigayaa:Bolts 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8,9.8, 6.8, 8.8,9.8, 10.9, 12.9Nuts 4, 5, 6, 8, 9, 10, 10
2. Macnaha koodhka darajada waxqabadka bolt:Lambarka e ugu horreeya: waxa uu tilmaamayaa xadka xoogga xajinta ee alaabta bolt.1/100 ka mid ah.σ= nambarka kowaad x 100labaad: waxay tusinaysaa xadka wax-soo-saarka alaabta bolt.Toban jeer xadka xoogga σ.Sigma.= nambarka koowaad x nambarka labaad x 10Tusaale: Fasalka 4.6 boltσρ=4×100-400MPa, σ, =4×6×10-240MPa3.Cadaadiska la oggol yahay ee isku xirka dunta ka eeg buug-yaraha 10-6 iyo 10-7
2. Su'aalaha xisaabinta
Qalabka birta ah ee tooska ah ee toosan ee cylindrical iyada oo loo marayo furaha iyo isku xirka birta, dhexroorka qaybta usheeda dhexe ee gear d=60mm, dhererka xuddunta L'= 100mm, qulqulka la kala qaado T = 5.5 × 105N.mm, saameyn yar shaqada, isku day in aad naqshadayso xidhiidhkan furaha ah.Xalka: 1) Go'aami walxaha, nooca iyo cabbirka furaha sababtoo ah xuddunta waxay ka samaysan tahay birta shubka ah, walxaha furaha waxaa lagu dooran karaa 45 birta, mana jiraan wax dhaqdhaqaaq ah oo u dhexeeya Qalabka iyo shafka, sidaas darteed furaha caadiga ah ee A-nooca caadiga ah ayaa la doortaa. Sida ku cad dhexroorka axle d=60mm, dhererka xuddunta 100mm, eeg Shaxda 10-9, Qaado: b=18mm, h=11mm, L=90mm.
