1. Ukuqiniswa kwangaphambili kokudibanisa intamboNgaphambi kwesenzo somthwalo osebenzayo, i-screw ixhomekeke kwisenzo samandla okuqinisa kwangaphambili.
1. Injongo yokuqinisa kwangaphambili
1) Ukwandisa ukuqina koqhagamshelwano
2) Ukwandisa ukuqina
3) Ukuphucula ukukwazi ukuzigcina ukhululekile
Ukumiselwa kokulayishwa kwangaphambili okushiyekileyo: 1) Akukho tshintsho kumthwalo wokusebenza: FR FR = (0.2 ~ 0.6) 2) Umthwalo osebenzayo utshintsha: FR = (0.6 ~ 1) F3) Kukho iimfuno zokuxinana: Fp FR = (1.5 ~ 1.8)
$ 10-7 Izinto kunye noxinzelelo oluvumelekileyo lweebholiti1.Izinto zeBoltIiBolt zihlelwa ngokomatshini wazo, kwaye umgangatho wesizwe umisela: IiBolts 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8,9.8, 10.9, 12.9Nuts 4, 5, 6, 8, 9, 12
2. Intsingiselo yekhowudi yebakala lokwenziwa kwebholiti:Inombolo engu-e yokuqala: ibonisa umda wamandla e-tensile wesixhobo sebholiti.I-1/100 yaloo nto.σ= idijithi yokuqala x 100Idijithi yesibini: ibonisa umda wesivuno semathiriyeli yebholt.Amatyeli alishumi kumda wamandla σ.Sigma.= Idijithi yokuqala x idijithi yesibini x 10Umzekelo: Udidi 4.6 boltσρ=4×100-400MPa, σ, =4×6×10-240MPa3.Uxinzelelo oluvunyiweyo lonxibelelwano oluthungelweyoJonga incwadi yesikhokelo iTheyibhile 10-6 kunye ne-10-7
2. Imibuzo yokubala
Intsimbi etyhidiweyo yezinyo elithe tye igiya ngesitshixo kunye noqhagamshelo lweshafti yentsimbi, icandelo leshafti ububanzi kwisixhobo d=60mm, ubude behabhu L'=100mm, itorque T=5.5×105N.mm, impembelelo encinci sebenza, zama ukuyila olu xhulumaniso oluphambili.Isisombululo: 1) Ukugqiba izinto eziphathekayo, uhlobo kunye nobukhulu besitshixo ngenxa yokuba i-hub yenziwe ngentsimbi etyhidiweyo, izinto zesitshixo zingakhethwa intsimbi ye-45, kwaye akukho ntshukumo ye-axial phakathi igiya kunye neshafti, ngoko ke kukhethwe isitshixo esisicaba esiqhelekileyo sohlobo lwe-A.Ngokobubanzi be-asi d=60mm, ubude be-hub 100mm, bona iTheyibhile 10-9,Thatha :b=18mm, h=11mm, L=90mm.
